so I just bought this '87 turbo 4runner. it's got an automatic (as far as I can tell...they all do).

I'm starting to look at upgrade parts, gearsets, lockers, etc.

what I'm wondering, is if I would get parts for a 4- or 6-cyl.

obviously it's a 4-cyl, but I had heard that the turbos had the same rear end as the V6. is this true? how about the tcase?

Try these links: mucho info

 

Check out my website for those parts you are talking about and let me know if I can help you out with something.

 

The quick answers:
The turbo4 rear diff is the same as the V6 rear diff. 4 pinion gears in the diff carrier, giant pinion shaft bearings, heavier housing.
Easy way to tell: 4 ribs on the outside of the turbo/v6 rear diffs. Only 3 on the 4 cyl diffs.

So yes, talk to wabbit for your gear/ locker parts for your turbo/V6 rear diff. The front is the same as all the other 7.5 IFS fronts.

The T-case is integrated with the automatic transmission. Not much you can do there except get another cooler and keep the fluid clean.

 

thanks for the links. I haven't seen a couple of those before....

but I figured someone could just tell me.

and I'll keep you in mind, wabbit. I like what I see!
