R33 2 Way Issue

[Ethan33]

hi, recently bought a new diff centre for my skyline (s2 33 gtst) the guy said its out of a 33, it was out of a s14 i assume, the issue is that the diff i bought and have put in doesnt have the abs sensor hole so my abs light is on, i like things to be right and i dont want the light on so is it possible to swap the 2way center out of the s chassis housing, and put it into my stock housing ? the second issue is the new diff has 4;3 and clearly my stock is 4;1 so i would need to change the crown wheel gear over onto the 2way centre right ?

so my theory was, un bolt the 2 way out the s14 housing, mark the 33 crown wheel gear, take the 33 centre out, swap the gear onto the 2 way and bolt it back in, will this work ? providing i get the gear exactly back in the same spot to avoid getting weird wear on the gears.

btw its a nismo 2 way. any help would be much appreciated!!

Don't do it yourself. Moving crownwheel and pinion fronm one centre to another and putting into different housing (from the new centre) means that it needs to be set up properly. Probably end up needing new seals as well.

I did exactly what you're planning to do. Helical centre + other CW&P into my original housing. Cost about $400 at local diff/trans specialist, including them supplying seals and shims and so on. Sucks to have to spend more $$ on top of whatever you have bought, but that's life.

cost me $600 for the diff. just annoys the crap out of me i need to spend even more money to get it right. bearings are a little noisey, may aswell get them done too.
