Title: What to put in my s13?
Post by: gtstCruiser on February 15, 2005, 01:53:47 PM
Hey all

I've picked myself up a s13 (sr20de) the exterior is pretty rugged but that doesn't bother me as im straightening it up and painting it myself.

But i am now starting to think seriously about an engine conversion.

My first thoughts were to get a sr20det as i thought that would be the best option. But researched a bit and flagged it.

CA18DET , RB20DET , RB25DET, VG30DET? , RB26DETT

i'm wanting to spend about 5 grand on the engine (not including the actual conversion) which i'll be saving up for over this year.  

The CA wouldn't cost near that much but i don't know too much about it and just want a bit of feedback.

Most s13 hybrids have rb20's in them. Plus their rev happy?

rb25's im not sure of as i haven't been in one. Maybe the VG30 and RB26 is a bit of overkill. But hey what a sleeper!!

I also mentioned the rb26 cuz i saw one on trademe for that price.


My purpose is just for daily driving (to work n back) but i thought if im spending this amount of money i might as well go all out.

So yea your thoughts and opinions are welcome.

Cheers

Just out of interest why did you flag the SR20DET?

The RB and VG's are a heavy lump of an engine so may mess up the handling with the extra weight over the front axle? Though as you say S13/14 RB20 hybrids are relatively common.

My thoughts would be that if you want the maximum amount of power, and aren't too concerned about cornering, then the RB or VG's would be the way to go. But if you want to keep the lightweight chuckable character of the Silvia then stick with a 4cyl - the CA if you have to or the SR20DET?

I have the RB20DET in mine.  It is aeasier swap than the SR.
CA18DET=  weak to start with but after 5k... might be something to fear )for others, that is)
RB25DEt= difficult swap due to the larger tranny (does not fit well into S13 tunnel.  But the main problem is wiring.  The S13 and R32 RB20DEt share VERY similar wiring architecture.  The R33 wiring is very different.  The R32/S13 has an Engine harness that stands by itself.  The R33 has many other items incorporated into it.  And it connects to the bi=ody harness in a different location than the R32/S13.
VG30DE  we tried this swap once, and almost pulled it off. The wiring architechture was similar (Z32) to the S13 but there were a couple of little things that made us put it on the back burner and we never picked it up again.  Sold the body and pickled the engine (for later).  The engine also had to mount to one side by about 30cm.  Cant remember why...

RB26DETT  same problems as RB25 and have to use RB25 tranny.  Both RB25 and 26 fit better in the S14 body and the wiring is more similar to the S14.

Dunno about the R32 RB26DETT wiring...never looked at one... actually.  Ive never seen an R32 whole.

hey thanks for that!

okay i'll be going with the rb20 then although i can buy a ca18det and manual gearbox cheap (about a grand)

Post by: cwald240sx on February 16, 2005, 02:57:14 PM
With 4 grand you can make a pretty nasty CA18.  but  I have an RB20DET in My S13 and My best mate has a CA18DET.  Both are stock with filter and exhaust.  Mine has a boost controller (set at .8bar)  And mine just crushes his in a race.  His is more fun to fling around and has a better torque curve for traffic.  I have to gun the crap out of mine to make it go...  But when it does :-) :-)

all im going to say is ANYTHING is better than a CA18 YUCK!

I think RB20 would be the best value for money, plus they sound and rev a whole load better than the SR- Just its the sacrifice of low down torque, but considering how light an S13 is an RB20 would go hard

whats so bad about a CA18DET???

There are people that are making some very good power from these engines RELIABLY!!

Heard about some guy not sure if he was in aus or usa that was doing 9's in his ca18 powered s13.

Theres a guy doing 11's with a lada engine as well, dont make it overly great. Any motor will do what you want if you spend the money on it

Oh i realise if im putting in a faster engine the brakes would have to be done im only just trying to set myself a goal to aim at.. makes saving easier.. sorta :P

13B's dont just pulse straight away tho do they, not familiar with them so yea.. what are they like as stock? I would really like one of these cuz its different.. anyone know anybody whose done this?

And with the rb20 while the engine is out, it'd be better to put a bigger throttle body on yea?

I was reading in some mag that they use a sr20de throttle body in the sr20det engine as its bigger, im assuming same thing would apply for rb20det and rb20de throttle body?

Note: My mechanical info isn't up there so most of what im talkin is crap just all theory :)

Cheers again

i once considered buying a mates s13 and RBing or rotorising it.. And it all comes down to money. Being a Z owner id love to see a VG30 in there, and tehy have been done, with scary results :) And by the way, the engines are quite cheap to buy. but itd be a bit front heavy. RB20 wouldnt be too hard, and from then youve got a strong relibable engine that can be tuned. dont bother with the RB25 or 26 unless youve got money to burn. The CA18 wernt a bad motor, and could happily make about 400hp at the fly with a bit of work, but the SR20det is actually lighter, and much stronger. As for a rotor, space wouldnt be a problem, but youd havta make some custom mounts, and change the wiring to support a carby n stuff..

at a guess (and doing the work yourself)
the VG would take 2-4G fitted (but youd need to upgrade brakes and susp)
RB20det 5gish
rotor.. god.. prob about 6 if your lucky.

gl dude.

Post by: Baffa on February 17, 2005, 03:29:47 PM
im guessing man.. never said it was accurate :)
but id imagine it would cost a couple of grand for the engine, then theres a bit of farting around to get everything else right.

Post by: cwald240sx on February 17, 2005, 04:09:29 PM
There is surprisingly little to buy.  All of the GTS-T piping will fit, as well as the GTS-T intercooler.  Or you can cut the bottoms off of the stock intercooler pipes and turn them.  Then weld them back on and they work great for a front mount IC.  You can install the GTS-T radiator but will need to remove the clutch fan from the RB.  Then buy an electric fan.  You will have to make a downpipe and also buy a pod filter.  Other than that it all bolt righ in.  Oh and you wil have to make a longer throttle cable bracket.  I made one from a $5 aluminum bar.  There really is very little to it

Baffa, i wasn't jumping on you.  Just curious as to your thinking:D

Nah the RB20DE and DET have the same size throttle body, and the AFM's are pretty damn big too compared to an SR one. With the power my car was making i dont think the throttle body was a hindrance, some people actually weld two DET throttle bodys into the intake as another option

Rb20 det + 5 speed.
Probably best bang for buck in a daily driver.
Or ca18.
Sure sr 20 would be cool but would cost more .

how dare you!

haha like I care.
Some guys from the 300zx club did a full non turb VG30 transplant recently cos the old one shat itself, and it cost them 2g all up, thats where the basis was for putting one in a silvia, as youd need different mounts and all that crap.
RB i had no idea, but it would cost you at least 2 grand for the engine, turbo and bits and bobs i would imagine.
i think sr20dets are actually dearer at about 3+ but again thats assumption.
and CA18dets are cheap, eg less than 1 grand if you know where to look but more than likely theyll be high kms and need rebuilds etc.

Id love to know the actual cost of dropping a rotor in there though. Just for a laugh.
would be different thats 4 sure

A guy in our club has an S13 that needs a new heart.  We have been tossing around the idea of butting a three roror 20b into it.  W are just a little scared of rotories.  None of us know anything about working on or modding them.  Not like a 20b in an S13 would need any modding.  That would be sick

A friend of mine in Texas is putting together the bits to drop a 13b turbo in a Miata.  Tell me that won't be nasty!!!

Post by: gtstCruiser on February 18, 2005, 08:36:52 AM
I was looking on trademe and the 13b's are roughly 3-4ish grand and thats with rebuild? so i guess another 2 to drop it in and mounts in stuff? 6 grand seems pretty good..

I like the rb20 and figure with the cash it'd cost to buy a good 13b i could prolly get a rb20det and exhaust n gearbox for about the same i think im not sure just assuming.

lexus v8 is worth considering,i remember an ozzy mag claiming that they can handle pumping out quite a lot of power without requiring internal mods.
they are a 4 litre? all alloy? unit.
should be able to pick one up from around nz$1800.oo?  what you save on the initial purchase and not having to mod the engine you will probably spend on gearbox adaption ect ect....
twin turbo would be nice also, probably wouldnt need too larger turbos either if you went turbo.
visibly quite a short engine front to rear, maybe mount turbo behind radiator, seen this done on single turbo v8 conversions, looks strange but hey if you wanna make the power who cares.

plenty of torque for a daily driver, and being ecu controled im sure you could tune some economic running into it at low revs.

rb20det is revvy and lots of fun , and can be economical as a daily driver, in this case you might consider purchasing a gts-t wreck so you can transplant the brakes,master cyl, and do a 5 stud conversion at the same time, hell it might have a good set of wheels still if you get one that has been rear ended, gear box you will have and the front cross member....... makes sense really.
replacement value for blown engine from$0-$1500 plus mods ect

rb26dett very cool but it will cost you alot more in the long run, this engine requires more maintanence .
replacement value for blown engine-5k plus mods reco ect

rb25det   i dunno, bigger turbo more cc's cant hurt.

Post by: smokey hayes on February 20, 2005, 11:05:24 AM
I say if you can afford it get a RB25, they are just as easy to fit as a RB20 and the extra torque makes it a lot of fun. They make good power with minor mods too.

There is a Lexus V8 powered S13 in Chch apparently it goes really well.

The RB25 is harder to fit in the S13 than the RB20.  We have done both.  The RB25 tranny is much larger and hits the tranny tunnel.  Some hammer work fixes that though.  Also the RB25 engine harness is way differnet than the S13 and R32 (whicjh are very similar.  We should be cranking the Rb25 car for th first time, tonight or tomorrow.

I have a 13B Twin turbo in my FD that gets 400km and gets thrashed everywhere.

I have a RB20DET in my cefiro which is my daily / Drifter and I thrash that too..... It gets around 400km a tank too.

So regarding the RB20DET being more economical I think your source is simply mis-informed.

Post by: RotorRian on February 21, 2005, 11:09:45 AM
Also the Rotary has alot more potential to modify than the RB20DET. The RB20 engine can't produce more than 400hp as the Head can't flow any more air to prooduce more power. The Rotary is pretty much unlimited by this as it has no head and you can just modify the ports. a 13B can produce 1000-1200hp. But at the end of the day its your decision but the RB20 is probabaly a cheaper option the RE is probabaly a better option but it will cost twice as much.

At the end of the day what are you using the car for ?

The RB25 fits EXACTLY the same as a RB25. The outside of the engine doesn't know the bore and stroke! :)
Easy fix, is to use a Rb20 trans... the 25 trans takes about 3 bumps with a hammer to get to fit.

Wiring is just as easy also. Hardest part is the temp senders range :D

1300Nm ?????

Is this 2Fast2Furious torque ?

So the RB25 Engine stock makes more Torque at the wheels than a 700hp Super GT Race car does?

I think your figures are wrong or more likely someone doesn't know how to load a dyno ?

Uncorrected torque is meaningless, unless you post the diff ratio, tyre size (if appropriate) and gear ratio.

(i bet i could make an rb20e make that torque stock, if i ran the right diff ratio and in first gear..)

Maybe we should test my Cefiro. Its a Hybrid RB20DET I think a goal of 1300Nm would be easy if we modify the diff settings :P

4th gear (1:1 ratio) std 4.1 rear end
As per any car without a speed cut.
Measured at the hubs


BTW, 600Nm at the engine is piss poor for 515kw..or is the kw figue 'corrected'??
A GTR with filter, exhaust and 1.1bar will make over 550Nm at the engine with 265kw atw.

We all know Dyno Dynamics correction DOESN'T work.
We had the sales rep blubbering for a reason last year as to why the power figure changed close to 20% when a different gear was used even though the unit knew engine rpm and roller rpm and could hence 'calculate' (if you can even use that word) ratios for flywheel correction.
Both pulls done 4 times, each under his supervision and loading...
Doesn't stand too well when they're trying to sell you $200k worth of gear..

Don't quote me on this -

I would believe that torque figure, if it's on a hub dyno.

Rotary, wasn't it a 20B that won Lemans????

I think the R33 didn't finish Lemans because of gearbox
problems, I think it was similar in specs to the 400R.

From what I have read, the R32GTR won the 24 hour at
Nurburgring, said to be - "the beautiest and hardest track
on earth", I think took 25 sec out of the Porsche's lap time,
for I think it was a production car.

If a stock rotary can win a 24 hour race at Nurburgring, that
would be something special.

The 20B was out of the Cosmo.

The 787B (1991 winner) was powered by R26B quad rotor.
There is a really neat video clip of the variable length intake runners in action.. pretty cool for (now) 15 year old technology

I don't wanna turn this into a Rotary Vs. Piston debate cause the truth is I own both and respect both engines for what they are..... Both great engines.

But here are the answers to your questions....

The LeMans Car used a R26B 4 Rotor Engine

654cc x 4 = 700hp + 600+ Nm @ rev limited 8500 rpm

The FD RX-7 won the Bathurst 12 hour production race 5 years in a row. Beating Porsche 911 & 968, Honda NSX, Nissan GTR, EVO & WRX, and Maseratti just to name a few.

Thanks for the opinions its good debatin what to put in the engine bay as your all more clued up then i am.

RE: What im usin it for.. is simply a daily driver, as economical as i can get, which RotorRian has kindly pointed out they eat around as much gas.. all dependin on how u drive obviously.

And i'm wanting to keep this car long term ( ie:yrs )  maybe the rb20det is the better option since it'll last forever?

I had a stocked skyline but i was starting to tire of the power i was gettin.. hence the whole engine swap thing. Maybe i can just mod the rb20det instead?

Now a lexus v8 has been brought into the picture for around the 2k mark, im assuming most engines are 2-3kish?

One thing that i was wondering about, when upgrading the engine specs of a car, do you upgrade the brakes to the same spec as the new engine you put in? or do you just have to have upgraded brakes than your stock ones?

This is a Nissan forum, we can bash rotars all we want. :dfinger:

And why would it be a bad handling FD? that makes no sence..
Title: What to put in my s13?
Post by: RotorRian on February 22, 2005, 03:39:40 PM
It makes perfect sence the 13B-REW is a Front-midship engine which means it sits its engine well behind the front wheels putting the center gravity & Mass to the centre of the vehicle. Like why Toyota used to run MR2 engines before moving to the V8 so the could get the Low Weight Intertia Effect of having a engine as low as posssible and behind the front wheels.

If you put in a heavy 6 cylinder you muck up the handling of the car that is designed around this whole concept as well as using a powerplant frame as a backbone through the whole car. You also have to scrape this as well. A 6 would be to heavy and too tall for the FD sure you could make it fit but it would never handle as well unless you restribute the weight around the car. But the the car get heavier etc etc you can see where it goes from there

This is why the FD RX-7 out handles most cars on a race track because the car suspension setup is as a race cars.

This was a SR20DET in a FD... a 4cyl with an alloy block.. and I also did not mention how it was mounted.
Thanks for the attempted physics lesson though.

I see no reason why a FD with a correctly mounted SR motor would handle any different?

Whats the fastest import in NZ and what does it run?? :dozey:
Title: What to put in my s13?
Post by: RH9 on February 22, 2005, 04:09:09 PM
SR20 is very light, a complete one can be lifted easily by 2 persons.  I have also had the displeasure of lifting a complete 13B - not much of a difference, prob a little heavier than the rotary.

Sure an RB is going to add some understeer tendancy to an FD but Sr would be fine. No real advantage though - the alloy block SR20 is going to struggle to make more power than a 13B anyway.

I rate them 3rd in strength behind the 3SGTE and 4G63T - both have cast iron blocks :)
Title: What to put in my s13?
Post by: RotorRian on February 22, 2005, 04:09:48 PM
Will a SR is an okay engine to use. Still heavier than the RE and still can't produce the power that the 13B-REW can produce but a SR wouldn't be too bad providing it was mounted far back but the RE actually sits 1/2 in the firewall.

Also the SR would sit higher but the SR wouldn't be too bad.

Whats NZ's fastest Import a 8 second SR coupe powered by a SR20DET.

Its two seconds off the pace from the Pro-Imports in Aussie Powered by Rotary Engines :p

An old Datto with an SR20, a bit unfortunate they went to all that effort with that combination - imagine if they did that work to something like an RX3 with a 13B? Or even a 20B :eek:    

I wouldn't be surprised if that car is one of the fastest SR20DET powered things in the world, if not THE fastest... so I wouldn't really compare it considering the amount of rotaries in the 7s, and even 6s.

Anyway, all this talk of rotaries is depressing me - I'm starting to regret my "sensible" R33 purchase and just gone for the real performance car.

I talked to the owners of that datto on why they chose the SR20. They said they wanted a Nissan motor to go with the Nissan frame.
They were considering a rotary.. but the owner went NO WAY! :laugh:

whoa gone off the topic a bit here boyz

At the end of the day im sick of my 1.8 under my bonnet.. and only considered the rotary as a different option to take. Don't we all do something to our cars to be different from others? Besides no one where i live has even heard of a rotary so i could just imagine pulling into town with everyone lookin at me thinkin wtf is that in there. But even then, i wouldn't give two stuff's if people were to give the 'why'd he do that' look.

This is my car, and i paid for it, so i want it the way i want, and i don't want others to have it! Pure selfishness here.

I've already straightened one side of my car and its half primered ( the one side ) still figuring out if i should roll the guards and how to hehe

Colours im painting it is a two tone metallic ford blue with honda metallic blue on the smooth lines (ie: top corners of the brake lights by the boot, top left and right guards, maybe the bottom of the factory skirts.)

And also a Jet Metallic Black/Clear Pearl (boot, roof, bonnet) colour i somehow made up hehe.. with about 10 clearcoats on top of that.

if only i knew how to pull my engine out and know what everythin did hehe.. might still do that!

If only i wasn't going on holiday to aussie for a week in 2 weeks, and she'd be done by now, instead im driving around with a half primered car thats very dusty! lol

Well the best swap is always going to be an SR20DET into a S13.. makes for a powerful car with great balance and the motor drops right in.. and this is going to be a lot cheaper if your not doing it yourself.

You can go and be different like me.. but it's a big headache and cost a lot more coin :(
Title: What to put in my s13?
Post by: Baffa on February 23, 2005, 02:01:22 PM
The SR is actually lighter than the Ca18, so it will equal great handling if done right. and they are actually mounted quite far back in the bay. you get rid of the radiator ran shroud and you can practically stand in the engine bay of some silvias. you could probably mount it further back if you dumped some of the lesser items and massaged the firewall but whats the point? yes the Rx7 is a great handler, and a good looking car, noone doubts that. But unless your under 5'9 dont bother buying one. yes it handles a bit like a race car but its got about as much space as one. silvias are great for every day use, practical, and i dare say more economical than a rotor, as well as being more reliable, excellent handlers, and as we no, great ability to push the envelope (read: drift :)

The RB will affect the handling slightly, but if you uprate the suspension it wont really matter as a daily driver. hell if you ripped out air con abs put the battery in the boot and so forth, youd prob be not far off the factory front rear balance.
your call dude. make it RB or SR though methinks.

sr20dets are really expensive tho. best bet i think would be 20det or 25det. I might have to do a bit more reading in the silvia forums.

gtstCruiser; forget the FWD SR's they are way too hard to fit in a RWD chassis.
I still say go RB25 the wide torque spread makes it much more tractable than a RB20 and that means its easy to drive, just the thing for a daily.

If the rb20 was so great then why did it need improving? which is why they developed the rb25.

Save some more money and go for the 25 and then make sure you have about $1000 a month put aside for tires :) :) :)

Post by: Baffa on February 24, 2005, 06:39:59 PM
RB25det is a better block but theres nothing wrong with a 20. its lighter and for general use its a great match to a silvia. As for the GTiR sr20 vs the silvia, originally nissan tuned the intake and chip and maybe the exhause to give it extra power for the little rally car. it was pulling about 220 stock, which made it one of nissans fastest factory cars. But if its too much of a @#$& to match to rwd then theres no point i suppose.

It met the same fate as the RB26DETT, can the same be said about that??  RB20DET ended production for different reasons.

R33s weren't mentioned anywhere - what relevance does this have?  It would also blow the doors off any R32.

Anyway - as for a motor for an S13, depends on your budget really.  If I was  on a tight budget, I'd probably go with an RB20DET.  If I had money to burn, and it were for drifting - a worked VQ35DE ;)

It was more a comparison why saying they stopped making the RB20 is irrelavant, and yes they stopped making the RB20 for 'daily' driver reasons, but considering the RB20 has a race history vs the RB25's 0 race history, i dont really think you can be putting it down for the boring 'it has no torque' excuse RB25 owners always whinge about.

The 33 mention is because most 25's are obviously in R33's, and they are not typically very quick out in the real world.

I was wondering how long before this R32 vs R33 war started.

I never said there is anything wrong with a rb20 but compared with a 25 it fails to compare.

And to keep the war going......Whats the quickest skyline in the world ....................................... R33

WTF man?  I have suggested the RB20 for the S13 (which was on topic) so I can't regard it too poorly.  

Maybe it would make this difference between an RB20 and an RB25 clearer if I got a print out of your old R32s highest ever power plot which was done on over 12psi, with a front mount, chip, road tuned S-AFC, full exhaust system, and larger turbo overlapped with my car with intake, catback exhaust and 11psi with a tuned S-AFC...   what you like to refer to as the "boring old torque excuse" will actually be presented a lot clearer as  what I see as "RB20DETs  have substantially less power, everywhere - even with more mods and more boost."  

In the real world, this means more acceleration at any given moment - with better response if you go with an RB25.  Redtop RB20DETs have a race history, they were before RB26DETTs...  the RB26DETT was around when RB25s came out - so fair enough... the RB25 doesn't such a race history, but imagine if the old GTS-R had an RB25DET in it??  

Oh yeah, the only RWD Skyline I've seen do a faster lap time around Manfield than Dave Duncan was an R33 GTS25t with relatively mild engine mods.

Dont you guys think this is just a little pointless?
The rb20 loyalists will point out its race history etc, and the rb25 supporters will adopt the thick headed theres no substitute for cubic inches attitude (enter Tim Taylor) lol
screw you guys, the RB26 is the better block haha :)

im not interested in debating and the competing with the 20 and 25, merely peoples opinions for what to put in my car.

And i wasn't talkin about buildin the fastest car in the world.

Thanks alot gtsr those pics are sick.

 I'll save up for a rb25det but realistically i think i'll choose the 20det as their alot cheaper, and also parts, oh and i want ur ecu still Gareth lol.

Although i was tired of the lag from my skyline, but i also think my turbo was going so that contributed to it. I think also with the money difference in the 25 and 20, i'd be able to sort that lag out with a few mods?

And since my silvia is lighter than the skyline it will be an advantage.

And lastly i wouldn't wanna jump forums as sdu has helped me out heaps here!

Hopefully my assumptions make sence when it comes time to part with my money.

:confused: Huh?Torque is what makes your car go faster not hp/kw or to use an old addage "Torque wins races Horsepower sells cars":)

Just quicker than most 32s:D Oh and what about r34 gtts dont they use the 25 in that car to?If the 25 wasnt a better engine than its 2 litre brother why did they stick with it in the 34s?they could have gone back to the more superior 2 litre:dozey: but they didnt.hmmm you think nissan know what they are doing??:laugh:
Really if you want to compare apples with apples your old 32 vs my 33 basicly same mods e.g step one turbo upgrade,fuel system,intercooler etc etc not sure if you had an ecu?I got 254rwkws but more importantly close on 1800 NM of torque now what do you think has more potential?Really this could go back and forth for ever the facts sometimes dont want to be seen.I think SMOKEY HAYES needs to take you out for ablast in his car gtstCruiser.From what I here its quite an experiance .:king: Though you are right in saying that the rb20 will be more cost effective with parts and to buy etc etc but somtimes when you want/need somthing better you got to pay a lil bit more.:p

An RB20DET will be good in an S13, as 2litres is pretty reasonable for a light car - so its still going to be able to provide pretty reasonable acceleration.    I know of RB20DET powered S13s, with both R32 and R33 turbos on them and they go pretty nuts.  

Sorry about going off the topic a bit with RB20 vs RB25, I reckon the RB20 would be fine for that application - I just don't like the risk of dumb comments being taken seriously.

I also think the rb20 will be good in the silvia.But if you want somthing more/better than the rb25 is it.I dont think any one has said the rb20 is rubbish ?far from it.:)
