Yes, you have to remove the whole rear and take it apart.

hehe i figured that: ( im just to tired to realize it, when i get a new clutch and actually have a day off, rofl, no one else reply casue the man has spoken and answered it, nah just kidding does anyone make a shorter gear,say a 4.10 perhaps?

:unsure:

4.10 is stock on all 5 speeds except 88 convertibles and the GTUs.

ok than a gearing thats lets you accelerate faster than a 4.30 end,i really going to sleep after one more post? :unsure:

The higher the ratio the better the acceleration.

i thought it was the lower the ratio the faster, but when i thought about it after like 5 minutes i was like im a fing moron, say you put the 4.30 ratio in a 88 5 speed n/a, its a really big difference?i know it would also depend on which model it was but i dont really know a whole lot about gear ratios,just havnt read up on them.thanks









i woke up :P

Yeah, you should notice better acceleration with 4.3.

Hmmm. So these 4.30 gears.... will they fit in the rear end of an '88 TII? Any difference between the gears for an N/A and a Turbo? I imagine pulling the diff out and opening it up and replacing the gears is a bit of a bear... Anybody here done this?

The NA gears are different. Racing Beat sells 4.375 for TII's. I've never swapped gears, but the differential is pretty easy to take apart.

That's coming from some one that can do an engine swap in a hour or two. https://www.nopistons.com/forums/pub...1047683785.gif

A GOOD engine swap will take longer than that. https://www.nopistons.com/forums/pub...DIR#>/wink.png

Its critical that you have it lined up properly, usually people dont do thier own gears, they have a shop that specializes in it do it for them. Clearences to check and what not. Its not a matter of just 'slapping in' a new ring and pinion, thats why there are shops that do it.

Losing teeth on a ring gear sucks period, losing a ring gear @ high speed may cause many other things to become broken which really sucks. These swaps need to be done by the pro's

The setup-up of the ring n pinion needs to be done by pros, The pumpkin installation is definately DIY!!
