Tranny Swap, Turbo Vs NA

Featured Replies

I want to put an 86'GL Wagon, NA, 5sp, DR, 4x4 tranny into my 86'GL-10 Turbo, 5sp Wagon. Is this possible? Do the axles and such match up?

 

Thanks

yes it is possible, I do not know if the axles match up (it would not be hard to swap them), but you will also have to swap the rear diff as the turbo's has a 3.7:1 ratio, and the 5-speed D/R tranny has a 3.9:1 ratio

 

BTW - check to see if you have a rear LSD (limited slip differential) they are a nice luxury, and can be converted from a 3.7:1 to 3.9:1 ratio

Also the turbo transmission has 25 tooth spline on the inner axle joint (DOJ) as opposed to 23 for all the other transmissions.

Just grab a couple of N/A axles and a 3.9 rear diff, your in business.

I did this swap on a '86 turbo 5mt (baccarudas car now) and it is a direct bolt in, the harness even plugs in for back up lights.

Awesome! Thanks! I'm gonna do it. If I don't have an LSD, I'll go find one.

 

This stuff will go along nicely with the 3/2 lift, 14 wheels and freshened motor I'm prepping for. I'm trying to build a universal kind of subie. I want a utility vehicle to make weekly trips to San Diego, a Pre-runner styled car for the high desert dirt roads and finally a crawler for the snowy mountain roads and trails.

 

Have Fun!
