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?

    • It only looks tidy, as most of the stuff that was on the whole back wall, is now in the trailer to go to the tip, or has been shoved in my 2.2x2.4m "Spare parts room", and now I can't get to anything in there Ha ha ha I could definitely do with a bit more space, but I'd just end up with your problems I'm going to enclose the car port beside the garage, and move a lot of stuff into it I think. OR... It will be setup as a fabrication area, and the main garage will have parts storage in it. I'm not sure yet... Need some pictures of that big shed you've got with the bikes and Skyline in
    • No. I think it's gone. 😭 I think you can get body coloured ones on eBay so I think I'll get one of those... Or just hang a red ribbon from the hole and whack a TOW sticker next to it.
    • Can't say I've had a bad experience with one on my car, then again it only gets washed once or twice a year... The wheels on the other hand, get a good spray often due to my shitty dusty pads.
    • @MBS206 thats pretty neat and tidy to me!  I'll get a photo of mine when I'm out there next. It might require multiple photos to understand the scale of the atrocities though... In total I have 4 sheds of varying sizes and layouts. Main shed is 14x8, second shed is 3x8, third shed is 11x2.5, fourth shed is around 6x4.  All are pretty much full.   The main goal of my cleaning tsunami is to make the main shed predominantly car and motorbikes only. Second shed is my metal fab room (2 x bench grinders, drill press, bench belt sander, metal band saw, scrap metal storage and some of my garden tools.  3rd shed is more bigger garden stuff, storage for engine crane, jack stands, concrete grinder, concrete mixer, air compressor lives there, and it now has two 2mx2m pallet racking shelves with itemised boxes holding building stuff, electrical stuff, plumbing stuff, etc, etc.  The 4th shed is Ryobi electric ride on mower, mini boom sprayer, ancient Kubota tractor, more garden stuff!  I have got a lot of shit....  Then there's the pool house (8mx4m) and the pool pump shed (4mx4m).  I built all of the sheds over the 11 years we've been here.  The main shed was a Ranbuild kit, the rest are all custom made to fit the areas available. Building the main shed taught me a LOT as I had no idea about building anything prior to that!  I've still got one more in me. It will be my man cave which I poured the extra concrete for way back when I poured the concrete for the main shed. The idea is the Skyline will be a centre piece of the main cave once (if...) it's finished.  I told my now 14 year old son yesterday that I will 100% drive him to his year 10 formal in 2 years. Still a long way off but at least I now have a date to work towards! 🤣
