yea with the intake pipe i did lose a little bit of torque. mainly down low. but i think the benifits of the sound is worth it. the power curve is very smooth. you will see that when it gets approved.

i knew my torque wouldnt be that good as with the larger exhuast. it would have been even worse with out the extractors.
um i was hoping for somewhere between 90 and 100kw. but because my car is a single cam i spose its not too bad. i was hoping to eventually get simialr results to screaming.

haha thanks, yea that makes me feel a little bit better. for the $1000-1500 i ended up spending on the motor i guess i didnt do to bad

haha yea N/A.. so much $$ for so much little power. i guess the next way to gain some good power is to remove the aircon?

i didnt buy my car to make it super fast. just to cruze round it.. so i think its done its job and lived up to its number plate (BADR33) cus those power figues sound bad in such a huge car  :laugh:

Removal of a/c will give a little extra power, and so would getting rid of the fan on front of your engine and installing an electric one, advancing the timing would also give a few extra kw. At a guess I'd think if the above mods were done it might give another 8-10kw?
I have a R33 engine manual (covering all engines in the R33 series), if you want info on how to advance the timing, send me a PM with your email address and I'll send the info.

yeah that is tru. i think i will keep my air con even though i never use it.. always handy in the summer time.

hmm yea i would like to remove that fan.. stupid squeely fan belt. but what do you do for the tempature senser for the fan?

yeah im keen to find out how to advance the timing. so i will pm you after this. it will probly all get changed back when the car gets its cam belt done in 9000ks or so.

should i plan any other work for when that happens?

if it was 8-10kw that would be a lot better and i would be happyer. i was gona do a ram air intake but i couldnt be bothred seting up the air pipe for it. lol. i woulda had the pod sitting above the dizy

im starting to seriously consider turboing this motor.. i just like it being NA.. i need money anyway.. diff is next on the list :)

That I'm not too sure of, the electric fan is one thing that I haven't really researched as yet, and only recently started looking into the subject, but from what little I do know about the subject is that a manual off/on switch controlling the fan is installed into the cabin giving the driver control over the fan.
Talk to screamin skyline, he has an electric fan installed into his car, he would be able to answer your questions on that subject much better than me ;)
8-10kw is a guess, alot would depend on how much advance you can safely run.

Mmm, yeah, I got an electric fan. Didn't notice any real power increase from doing it. The standard visco fan has a clutch mechanism in it so it doesn't drag bugger all power from the motor anyway, unless it's stuffed and locked in.

sweet as dude, where did you put the senser for the electric fan? i know of a few people who have been considering it on there skylines. i just want that fan belt gone!! haha. i dont think my fan is stuffed but i will have a look next time.

is it worth gettting a larger throttle body? or will i lose power? will it work with the factory computer?

screaming what do you think of my results? any idea on how to improve it? im just so shamed. haha

My fan is just on a switch. I've got a thermastat for it but they can be a little tricky to set right. I'm just in the process of hooking up an aftermarket temp gauge so I can keep a good eye on it.

I think Skyla might have done some research into the throttle bodies.

The standard throttle body for the N/A RB20DE and RB25DE engine is 60mm, you can get the factory throttle body enlarged to 64mm at a cost of about $200-$250. I'm not really sure of what sort of gains can be made but think I can remember someone saying 4-5kw, but I haven't seen any dyno reading of before and after to prove those figures.
The ford XF falcon throttle body (64mm), can be modified and fitted to a RB motor.
If you want to get your throttle body enlarged, or get a XF T/B modified to suit a RB engine contact RIPS here on the forums.
Another option is the Q45 throttle body (80mm) found on the Nissan V8 engine. This is not a direct bolt on to your factory intake, you will need a custom front facing intake to take this big puppy, Unless you have got a highly modified N/A engine, this T/B would be an over kill and bottom end torque will suffer.
Here's a pic of the 3 T/B I have mentioned, the RB T/B is in the centre, the XF T/B on the left, and the very large Q45 on the right.

Clean R33 if i was you id be either staying as is and thinking economy economy economy or id be dumping a turbo or RB25DE in my car. Your spending good money on a very basic engine that was never intended for performance, and it will take a helluva lot of money to get it where you want it.
If you save up and get a RB25DE you can stay non turb, and do the exhaust, air filter, extractors, under drive pulley, advance timing, biggr throttle body, and if you wanna go nutty, oversize vavles, head flowed, ported and polished, cams reground, rev limit raised.... NOW your talking.
more power!!

haha yeah i know. what i should do is sell my car and buy a rb25det r33 4dr. probly have to convert it to manual but that would be sweet.

what i will probly end up doing is saving up and waiting for the mechanical waranty on my car to die. i will either put in a rb20det cus its cheep. or save up for ages and do the 25de or 25det conversion

they did have a factory rb20et so thats a turbo single cam. i know its not gona knock my socks off or pull huge power figures but its the best way to get more power for like 1k or so. even thought id onlybe running say 6psi. im not doing all this to make my car go fast or have huge dyno figures. i just want to be different.

i could always do what they guy did on the aussy skylines forums and drop a 4ltr v8 in then super charge it. he is making about 330+hp at the wheels is what he has at the moment from memory

all that i really care about is that i have a skyline and it gets me from a to b.. unlike my last car similar to DKZs car witch i spend like 4-5k just getting it running right cus the motor was shot and i got muckd round by my old garage doing expencive work with out asking

sorry if i sound like im ranting but iv had a fully sh*t day

Nah its all good mate.

Realistically you need to think about what you want from your car.

Imho your best saving your pennies while you still have a warranty (which by the way may be voided if you do certain mods) and save up for a new engine/frontcut. the RB20DET is cheap yes but in the end after every little drama its not gonna save that much money over say a RB25DE or RB25DET and with a smaller engine the heavier R33 will suffer.

I say do it once and do it right, youd be gutted if you spend 3 k from start to finish installing an RB20DET and getting pissed on by a stocker R32 GTST.
Spend a bit extra, even if it is 2.5 non turb and get a good all rounder.

If your in auckland i may one day drop in to a SDU meet and take you for a ride in my 3l V6 non turbo Z, and show you how much fun a good size mildly modded non turbo engine can be :P
