HR31COUPE Posted November 9, 2004 Share Posted November 9, 2004 I'm wondering if anyone knows whethera R34 Tiptronic Auto box is the same physical size as a R33 Auto box. The reason for this is I am looking into buying a RB25DET NEO & Tiptronic Auto to go into my HR31 Skyline. I know for a fact that the R33 Auto boxes fit but I am unsure on the R34 type. I have also read that the Tiptronic box needs the standard ECU to communicate with to operate properly, any truth to this? not that it matters too much as I'll have the ecu anyway. Any info would be greatly appreciated. And yes, I have done a search on this topic but could not find the appropriate answers.

NJR 34GTT Posted November 9, 2004 Share Posted November 9, 2004 Standard ECU is required. Nearly all aftermarked ECUs wont work with the tiptronic box. There are a few options but none of the usual options like Power FC. No idea on size wise sorry.

Abo Bob Posted November 9, 2004 Share Posted November 9, 2004 There's about 18 connecting wires going between the 2 ECU's. Link to comment https://www.sau.com.au/forums/topic/55497-r34-tiptronic-auto-boxes/#findComment-1082490 Share on other sites More sharing options...
