RB30DET in S13.

Lowered 10mm and a mad bonnet, should do it just fine..

Bonnets are overrated . Gotta see your S13 sometime Ben, sounds like it's coming along alright .

wouldnt a laurel x member fit? or cefiro? considering they are based on a silvia chassis and have RBs in them

They're the same as a Skyline ones.

i run an rb20det in my s13. i used all the stock r32 equipment. everything bolted up fine. i added spacers to the hinges on my hood(bonnet) and it shuts. the shifter is a little closer to the radio. the motor does sit a little high and forward. but i'm used to it now. the sr/ka driveshaft will slide right in. just have to swap out the RB speedo cable to the sr/ka electric speedo sensor

Reinstalled my engine in the weekend.

With the engine lowered and the reinforcing removed from the bonnet, it almost closes with the RB30

Only going to need a slight lump.

Sounds good Ben.  What method did you use to lower your engine?

I really want to get mine going in time for the 4 and rotors but I'm not sure if there's enough time to get it done and all certed etc.

Hello GT-R Ben, what's the mods necessary to make the RB26 box fit the Silvia Chassis?  I have a S14 and I assume I still have to make a custom driveshaft, or do I?

[cwald240sx]

Your going to have to fabricate an entire front suspension if you want to make it AWD.  Otherwise just use a 25 tranny.

[GT-R Ben]

We were not talking AWD/4WD Cwald.

I have removed the chain and gears from the transfer case, had a plate welded onto the side.

In the S13 tunnel i needed to make some more room around the starter motor lump, and a small bit down the side. Apart from that if fits great.

I had to have the engine tilded back as far as possible and having the engine lowered 15mm helps. All it took was the heater hoses to be in the way and I couldn't tilt the motor back far enough to get the box on..

I will take some photo's.

I would have just used a 25T box.. but I had a spare RB26 box and it already had a busted transfer case. So it's better than spending $2000 right?

Prolly so:D

Thanks for the quick reply.  

The reason why I asked is because most people here in the U.S. have to purchase the GTR motor/tranny/harness/ecu combination and would require extra $ to purchase a RB25det box (which prices have gone up a lot and is getting harder to find)

Photos would really help, thanks Ben

1. On the RB25det/S14 swap, we needed custom driveshafts.  I'm wondering if you used custom driveshaft or ?

2. Can the Z32, GTR rear subframe bolt on to the S14? We in the U.S. is suffering from having to custom make axles since the stock S13/S14 axles break.  The Z32, GTR rear subframe(diff, axles, etc) is really cheap to obtain, and would handle the torque well.

In our RB25 S14 we had to make a custom drive shaft because the S14 R200 diff takes a smaller yoke end than the RB25 tranny.  The S14 and Z32 non-turbo use the same diff but different subframes.  We also have a Z32 with about 550hp.  It started life as a non turbo car, so it has the smaller R200 diff.  We elected to keep it until it broke because of the better (for us) gear ratio.   That car has a OS Giken twin plate clutch and MT slicks.  It runs 1.65-1.69 60ft times and we have had no problems out of the smaller R200 diff.  They are bulletproof.

The Z32, GTR rear subframe(diff, axles, etc) is really cheap to obtain, and would handle the torque well. What I'm referring to is the Z32 turbo, GTR subframe does it bolt right up(minus the rear hand brake mod) and it's the axles that break, not the R200 diff....

[cwald240sx]

Ahh!  gotcha on the axles.  I think the Z32 and GT-R have a wider track than the S14.  Not sure on that, so I'm going to leave this one alone and let someone else answer.  Bolting that R230 diff into an S14 subframe is going to be interesting if subframes wont swap.

[hybrids14]

Hrhr, that's why I'm asking GT-R Ben since he has the GTR diff..
^^

Yeah, the wider track is perfect for my widebody conversion.  I know a guy that does make a kit for the installation of the R230 diff into a E36 BMW, but I'm not quite sure what setup he's running on the S14.  But I do know that he has the R230 diff and GTR axles.  Can't find him now... so the questions remain....
