R32 gts25

[HarryRFB]

Hey guys, just wondering how many people here have built s0 rb25s, I’m building a fully forged one atm but am interested to see how much power others are making and what parts they have as I’ve heard the r32 rb25 has different intake manifold and wondering if rb20 would work, also anyone put a r34 big box into a r32 before and how much wiggle room is there? Cheers

22 years of this forum would hope so 

use the search function plenty of information.

I have a forged rb25, yes it makes good power, I run the r33 gearbox(in a schassis, its tight), Use stock manifold or a plazmaman plenum.

And because I am in a good mood, read everything.....the reread everything then ask questions. Everything has been answered.

Yes. It's easy. Only with the caveat that you will have to convert to pull clutch (which kinda sucks) and you will have to fabricobble a speedo drive together using one from an early 90s Navara (same big box as R33/4, cable speedo).

Oh, and of course you will need the correct gearbox crossmember (I can't remember if it is A, B or C and it probably depends on whether the car was auto or manual to start with also), and you need to get the front part of an R33 or 4 tailshaft cut and shut onto the R32 tailshaft (the cut and shut happens in front of the centre bearing section - you cannot just use the whol efront section from any other car - nothing is the right length etc).

Or you can just convert the new gtt box back to push with the factory stuff.
