180SX Blown Diff - GTR Upgrade Questions

1.5J 180's Photo 1.5J 180 05 Jul 2017

Hey,

So yeah the diff let go in the 180SX last track day. Thought it was an axle which got me looking into upgrades, and led to a GTR conversion for a reliable rear end.

Have done some research about bolting the GTR components into the existing subframe etc. as a 'bolt in' job but can't find some clear answers I'd like answered or some help.

I understand I will need the GTR diff and centre, driveshafts and hubs as the components, using the existing diff rear cover to bolt into the subframe, plus input flange to the tailshaft. Correct? The 180SX is already five stud with skyline rear brakes.



Questions about how 'bolt in' this all is?

1. Are the GTR axles the same length as the 180SX 5 bolt axles, will everything bolt up okay with suspension components etc?

2. Tailshaft length using the existing tail shaft (aftermarket and cut for the R154) and 180SX input flange. Will the 180SX input flange bolt into the GTR diff and will the driveshaft length need modified?

3. Are the 32 and 33 GTR diffs the same in term of dimensions and compatibility etc? Or which one do I need

Anything else I'm missing there.. Any experience or input would be great.

Cheers

swap rear housing for 4 bolt R200 rear
change the imput flange on diff for silvia 4 bolt one ( rattle gun and all done)
swap hubs for GT-R ones
half shafts arent exact length but as long as not running drop knuckle should e be and isues

Thanks mate, appreciate the info.

Should be standard knuckle so no dramas there.

Believe the 32/33 GTR diffs are the same for bolt in purposes, just not V-SPEC which have a hydraulic pump correct?

Do you know if the tailshaft needs to be shortened i'm guessing?
