TII trans

NoDOHC · 09-30-2009, 06:04 PM

Out of curiousity, what is your reason for wanting to upgrade? If you want an NA transmission, go to eBay and buy one for around $75.00 any day you want one.

The turbo transmission will require a custom driveshaft to connect to the NA diff (different splines). Plus it will require a lot of electrical work (the wires for the reverse lights, 5th gear switch and neutral switch will not reach). The NA trans will take NA power just fine (if it starts out in good shape).

I have killed two of them, but both were old to start with and I am making 160 Wlb-ft of torque (200 Lb-ft at the flywheel).

My buddy's just went out and i have a spare tii trans and i was just gunna let him buy it off of me. but since it would be easier and chaeper for him to just buy an n/a one he'll just do that.

You can get such a driveshaft from Mazdatrix and all I had to do for wiring was to extend 4 wires and change a connector, not really what I'd call "a lot of electrical work".

Yes it has the right connections for the TII trans and NA diff, but it's really too short to be a decent solution. You can probably find a driveshaft shop in your area that can extend it for you though to make it a proper solution.

How much longer? 10-20mm or longer?
thanks

It was more like 1 foot, but then I had some slack left at the end.
