What Diff Can I Use In My S15?

[toy515]

hey guys im done a rb26 conversion in my s15 and i want to change my diff and my ratios im not worried about abs sensors or speedo sensors as im going to run my speedo of my gearbox. id rather not change my rear sub frame? if i change my half shafts to gtr will i have to change my subframe? whats the best diff to use without much modification?

thanks

If the S15 has a R200 diff, then just swap the gears (C/W and pinion) from a Skyline onto the S15 centre.

A Stagea set will give you 4.083:1

A GT-R (R32. 33) set will give you 4.111:1

A (R32) GTS4 set will give you 4.375:1

i have a set of 4.11 gears out of a 33 diff which will suit ,also have 4.36 from r32 both r200 diffs

I also have a 4.11 centre and shafts from an R33 and I'm looking for an S15 3.692 centre. Are you interested in swapping? Hoping we can work something out!

Does anyone know whether the half shafts need to be swapped with the centres? Mine's from a 25t.
