Gtst4 Diff Question

[burnoutnut]

hey fellas

im currently building a drift car

using parts off this car...

now ive run into a little issue the motor and gear box i have is an rb20det gtst and the chassis that its going into is a gtst4...now the drive shaft attachment (on the diff) is different from the gtst to the gtst4

i cant swap with diff coz they are bolted to the cross member different ....

here is what im talking about

ideas?

Have you considered the obvious option of just either changing the input flange from one diff to the other, or using the back half of one tailshaft with the front half of the other? (Obviously the second option would need to be balanced afterwards).

[burnoutnut]

only have the gtst drive shaft....

changing the imput shaft is one option but not that familiar with diffs

[GTSBoy]

Get a rattle gun. Take off the flanges and see what happens.

[burnoutnut]

need to drain the diff oil?

[GTSBoy]

Shouldn't think so.

Centre punch the nut and pinion so you know where they line up, get rattle gun, unrattle, pull off flange and put teh gts-t flange on, rattle back up so the punch mark is only just past the pinion mark and you should be right. That is the cheaters way as you loosen off the bearing preload but for a drift car you should be right
