'87 turbo 4runner drivetrain questions

Numbchux · 11-28-2006, 11:04 PM

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?

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.
