R34 auto box into r33?

[Gts25t Bruh33]

Hey there lads,

Ive looked around a little bit and have come up empty handed. Is it possible to run an r34 gtt auto gearbox in an auto r33 gts25t? Have you heard of this being done before? If its possible what do i need to do it? Im sure a lot of you are thinking why on earth don't I just go with a manual but any help is well appreciated. Cheers

R34 auto's TCU is in the ECU.  The likelihood of being able to run it (given that it's got tiptronic functions) with the R33 separate TCU is pretty slim.  Might be doable, but not likely with a satisfying result.

Using the R34 ECU to tun the R33 engine and transmission should actually be easier.  You'd have to put a Nistune into it, so you can rub out all the error codes that will pop up from not having the traction control and boost sensor and such.  And you'd have to do a little re-wiring of the odd sensor here and there.  And the air-con might give you a bit of extra work (or it might not).

Basically, it is not simple.  It's a full on project in its own right.

Or put the whole engine/trans/ecu package in...best option if budget allows.

Cheers for all the advice. Lots of helpful info, with my current budget and knowledge of skylines i think im just gonna manual convert for now. Maybe just pick up an r34 later down the track. Cheers once again
