Rb20 To Rb26 Conversion For 92 Gtst

[Courtney]

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.

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...

[R31Nismoid]

agreed, or -7's as its a RWD

[johnbarry88]

or you can go with the trend of a single gt35r up to you but if you want simplicity then the single is the way to go..

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?

[joeleo87]

change the turbos while they are out, its a must!

Ive just had mine let go i got lucky though because it didnt destroy my engine
