Diff Ratios For A R33

[WHITER33GTS-T]

Im after a different diff ratio for my R33 GTS-T. I currently have a 4.1 ratio 2 way diff. I want something with a taller ratio like a 3.7. I have a C4 box and it revs a bit high on the highway so want something else for the street.

What other ratios can you get for a 33??? Or what can I use to have a diff made??

just go to a diff joint man and ask them to change the internals in your diff.... i dont understand why you would wanna change to 3.7s in the ass... your car will go nowhere till about 80k then youll be setting land speed records. lol.

I have a strong 25/30 and 3800 stall. I will keep the 4.1 for the drags but want something better for the street so its not reving its ass off on long drives.

If anyone can add to this list, either if its ratio or cars that we can find the diffs in.

Are any of these diff gears compatible with a R33 GTST non abs diff?

S13 SR20DET Auto, S14 SR20DET Auto, S15 SR20DET Auto, A31 Cerfiro RB20E. 5 & 6 bolt

Do any of these diffs have the same diff hsg as the R33 GTST diff? ( R200 i think)

Cheers,

provided the car isnt a factory manual

r33s come with 4.11 in manual and 4.3 in the autos as they are need the diff to compensate for more gears in the manual.
