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

Thanks for that, already had it welded with addition of tomei baffle too :cool: forgot! Yea I want to fry my box :D will replace it later

^^^ 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...

After a quick search here are the threads id be reading if in your shoes :/

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?

    • Block bump. $400. As above cyl 6 needs bore or sleeve.
    • I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.
    • I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.
    • From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.
    • They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
