SmItZ Posted September 29, 2013 Share Posted September 29, 2013 I'm looking at putting 3.7 ratio gears from an R34 GTR diff into a R32 GTR diff. Just wondering if this will fit?

GTSBoy Posted September 29, 2013 Share Posted September 29, 2013 They should do. They're both just R200s. You have to do the front too.

GTRsean Posted September 29, 2013 Share Posted September 29, 2013 Diff ratio is 3.55:1 for 34GTR, and as said above swap em in, might have to use the non vspec rear crown and pinion gears only though...

KiwiRS4T Posted September 29, 2013 Share Posted September 29, 2013 Somebody does make an aftermarket 3.7 diff for the R34 but whether 3.7 or 3.545 I would be interested to hear of a successful conversion as its on my to do list as well.

Ahhh yes, my bad it is 3.5! Thanks Somebody does make an aftermarket 3.7 diff for the R34 but whether 3.7 or 3.545 I would be interested to hear of a successful conversion as its on my to do list as well. I'll probably do the conversion soon as it sounds like it fits. Will post on here once I do.

s13gtr Posted June 6, 2017 Share Posted June 6, 2017 and dont be fooled that you can use r33 de auto diff gears as it is very close but different at 3.583 Link to comment https://www.sau.com.au/forums/topic/432526-will-r34-gtr-diff-gears-fit-into-r32-gtr-diff/#findComment-7833339 Share on other sites More sharing options...
