should just bolt right up exactly the way your n/a did.

a t2 trans is not the same as an NA. youll need to modify the driveshaft to make it fit. you need a new clutch and flywheel too.

what do u mean u have to modify the drive shaft...do u mean shorting it

Look at my sig... you'll notice I've DONE this swap.

What you will need:

TII transmission
TII flywheel
TII clutch
TII pressure plate
TII clutch slave cylinder
TII starter
Some wires and some butt splices for those wires, to extend the wires on the tranny for the backup light, gear sensor, etc.

What you have to decide:

Do you want to keep the NA differential and modify the driveshaft to fit, or do you want to swap the differential to the TII unit and use the TII driveshaft. The TII driveshaft has a larger yoke because the transmission output shaft is bigger and is splined differently.

You can either have a custom driveshaft made, or you can use the TII driveshaft and TII differential and halfshafts, brakes, etc. If you have a 5-lug car the brakes are the same. You MIGHT also be able to get the TII driveshaft modified to fit the bolt pattern of the flange on the NA differential, but I suspect that would be difficult to do. Compare the driveshafts side-by-side and you will see the obvious differences.

One point worth noting: It's easier to swap the ENTIRE rear subframe assembly than to change just the differential and halfshafts. If you need details on how to do that (I did it) I'll be happy to help.

The driveshaft from an Auto will mate with the TII tranny and the NA differential.

You sure about this???

And Ragtop, can you give me some pointers on swapping the rear subframe? BudddyRX7 and I are going to be attempting this one soon.

Mazdatrix says it will work.My factory workshop manual says the auto driveshaft is almost an inch shorter than the TII one.I called and mentioned this one time and they still said it will work so I don't know I may try it oneday.

I was also told this by Mazdatrix. Haven't tried it, just rebuilt my tranny instead.
