What Diff Do I Have?

[clip14]

can anyone tell me what diff i have from just these details?

1991

coupe

auto

gts25

hicas

its been converted to manual but i think it still has the auto diff as the gears are really tall...

[GTS4WD]

Open diff.

NA's have open diffs

cheers for the reply, was hoping to see if by the car specs someone could say whether it has a r180 type diff or r200 etc. just so i know what i can swap in. and also a recommendation as to what sort of ratio i should use.

the engine is a 2.5L and will stay n/a for now, so a short ratio would be good to make the most of the lower power of a n/a engine.

anyone? I can post a pic if that would help, but it was tough to get a good view without jacking the car up (its raining outside!)

but i heard somewhere that skylines which were optioned from factory with hicas had r200 diffs (which mean i can swap in a shorter ratio lsd diff from a gtst).

The ones ive seen are R200's and 5 bolt shafts so same as gtst but not lsd and 3.5:1 ratio

I think you might be right there

the plate in the engine bay reads

RE5R01A RC35

does that mean i can swap in a gtst diff?

r32 or r33?

do i need to get an abs diff or will it not matter?

cheers for the reply

R32

If your car is abs you will need a abs diff. A gtst diff should go straight in but it would still pay to check yours to make sure before getting one.

here are some pics

seems to be a 5x1 r200 with abs.

can someone please confirm?

cheers

yep looks exactly like a 5x1 r200 with abs diff. You can use a r33 diff to if a abs r32 diff is hard to find, you just have to swap the alloy backing plate so it bolts in.
