Post them up, I would love to see them. Did you give any consideration on keeping the twin turbo setup and upgrade the turbos? What size turbo are you going to be runing on the rb26, gt42r?

 

i had thought about keeping the twins, but to be honest, the amount of work and plumbing required to keep them is just too much time and money

-2 downpipes
-1 "merge" downpipe
-2 hot pipes
-2 inlet pipes
-2 oil feed lines/drain lines/coolant lines

its just so much and so over complicated for the twins that it makes so much more sense to go to a divided twin scroll t4 inlet, single 4" downpipe/exh, single charge pipe, single inlet pipe, single air filter, etc

My car is designed to run the GT4088R and the GT42102R. Ill be trying both turbos out and use the one that i like the most. Im thinking it will be the 4088R as i can make just shy of 800whp on it and have instant spool/response

 

Post pics asap when finish.

 

A cheaper/more unique option may be an RB30DET build.

People use the bottom end of an RB30 combined with either an RB26 or 25 head and get awesome results.

The RB30 only came out in the old R31 Skylines as well as an Australian car known as the Holden Commodore between '86-'88 (give or take) and this was known as the VL model. It's just a 3L inline six and only came out with a SOHC 12 valve head afaik.

Yeah they're old engines but you're rebuilding the engine anyway. And you could buy a good RB30 for like $100.

One guy bought an RB30, rebuilt it to factory specs, used a completely stock cylinder head from an RB25DE (DE = non-turbo) and cranked 500WHP through it and compaigned it successfully for a couple of years. www.rips.co.nz

Another guy did the same thing using a cheap RB30 He found at pick-a-part for $50. His was only making 460-ish HP in a tube frame car but it ran I think high 9's or maybe 10's. He's since rebuilt it running a T51R.

With this you also have the option of using the RB26 Head, or using a cheap-as-chips RB25 head that'll probably work just as well. Although, RB26 is designed more for high-RPM abuse.

Just remember, you'll also need the box from an RB25DET. These were 2WD and are stronger than the GT-R boxes.

 

Good luck..

 

sorry for no updates, ive been super super busy with the shop. im going to be working on the car all week and weekend starting tomororw so i will be sure to post some pics when they are worth looking at

 

I've always wanted to throw a Skyline engine into a 240Sx converted into an S15 or S14. Kina a deam of mine. A S13 with a rb26dett would be cool too. good luck to ya.

 

RB26 into S15's have been done before. Would be very cool I'd imagine.

Tein suspension has a track-spec S15 with an RB26 but I've never seen it in action.

 

is that the one where the motor is moved back into the firewall? ive wanted to do that using a g35 or 350z firewall, it would be a cool RWD project

 

for 4 grand you should be able to pick up a used rb26 with transmission. My buddy did... 3800 for rb26dett w/ trans, 64k on it.

 

also you could be different and swap a 2j in it =] easier to wire and parts are easier to get =] just an idear

 

Thats what i was gonna suggest. Theres a guy here in GA that has an S13 hatch with a 2J. Hes making 600 hp on a turbo upgrade, fuel upgrade, and AEM standalone. Its a pretty sick car! My next project when i move is going to either be a 240 with a 2J or an SC300 with a 1J. I love the Evo, but i miss my 240 w/SR and i miss drifting...

 

actually that is a much more difficult swap to wire. also there would be no AWD, and illegal for all forms of racing (no cross MFG motors/chassis allowed)

 

you should learn how to turn the FWD off when you want it... then go drift

 

Geoff I would love to see more pics when you have a chance!
