1.5 Way From R32 Gtr Will Iy Fit In R33 Gtst Housing?

[nistst]

Hey guys does anyone know if a nismo 1.5 way out of an r32 GTR fit in an r33 GTST diff housing?

Cheers guys

Centre will fit, bolts that hold the crown wheel on *I think* are a different size..

Halfshaft splines may be different but I don't think they are.. someone will correct me if I'm wrong anyway

[nistst]

So the bolts that hold the crown wheel on are they massively different or.....? Am i going to be able to use it and will it cost me any money?

bolts are the same. m14x1 axles wont. you need the "nismo" stub axles to suit your driveshafts. as the nismo diff will have 31 spline and you dont have 6 bolt flanges.

You sure the bolts are the same? When I was looking to change gears along with my 2-way, I discovered that 33gtst crown wheel bolts were bigger than 32gtst (m12 I believe), so 32GTR is same as 33gtst?

yes. the gtr and 33 gtst are the bigger ones. usualy the nismo diffs come with sleaves for the small bolts..

My Nismo diff was bought specifically for 32gtst, came with its' own m12 bolts, a pair of new stub axles (standard Nissan items but 2x shorts instead of 1x short 1x long), a gasket and some oil. Ended up using an auto S13 crown wheel and housing (so I didn't have to change pinion gears out) as it was all straight bolt up.

Interesting to know 32gtr and 33gtst are the same though

cool. why didnt you just use your crown wheel?

Changed ratios from 4.3 to 3.9
