Hey,

Converting my R32 gts-t from RB20 to RB26.

Has anyone here done this before? What difficulties did you come across and is there anything I should know beforehand?

ATM I have the 26, PFC and harness, which is all I need to get started, I hope. :cool:

Thanks ppl!

GTR Sump needs the diff chopped out and welded up to get it in (as you'll notice)

You might need to 'massage' the firewall a little depending on your choice of dump pipes (i had to im my HR31)

RB25 box needs a different crossmember (thats from memory)... as i hope your not using the RB20 one, it wont last long at all.

Thats about it, motor/loom and just power it up and should be fine.

Change the O2's while its out too, and the turbos... (if you can) $$$ job later and costly if they let go and kill the motor

^^^ too true all the import 26's i've got over the years pretty much shit the turbos after as little a month... they really dont like sitting idle. in the scheme of things a set of cheap garret 2860's would be a wise investment...

If there's any other questions i guess you could start anoter thread or PM the guys that have done it before. Id also go to a few workshops and have a chat with them about what you want to do as they may have some info for you, or even a quote so reasonable that its not worth your effort to do it yourself ;)

What are your plans for it? Twin turbo, single? Mega power sort of thing or a daily driver?

      From Japan and back to Europe, my sh*tbox R34 GTT

      By GoHashiriya · Posted

      Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.

      Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?

      I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
