I bought an 88 parts car with a running motor to swap into my 86.

Sure, they will mate up, but I want to know what all needs to be done so everything is copacetic, I noticed when pulling the motor out that I had two EGI boxes on the passenger floorboard, N326 and N327 I believe, while I only have N326.

This is the one from my car:

What all needs to be done as far as wiring, because I know it will mount up.

 

Search says this is a TII transmission?

Correct?

The motor however is NOT a turbo.

So, 88 NA motor with TII transmission, receipts say there is a Turbo Excedy clutch, what wiring is different.

 

It is a TII transmission. From the FAQ:

Someone else will have to chime in with what wiring is different as I never have done the swap, I only remembered about having the entire drivetrain from a TII or a custom shaft made to mate up with the N/A differential.

 

to be more specific it is an S4 turbo transmission.

If you're going to use the turbo tranny i believe you will need the turbo clutch slave as well.

 

Will I also need the turbo driveshaft and differential?

I was told by a friend that the spindles on the NA driveshaft don't match the Turbo transmission.

 

Like stated above, you will need a Turbo to NA Driveshaft, like the ones offered on Mazdatrix if you want to use your current rear end, else yes you will need the turbo drive shaft, Turbo Diff, and Turbo Axles.

 

the only wiring that is different is the S4 uses spade connectors. S5 uses bullet style connectors. but i don't believe any wiring changes between TII and NA.

 

yes, there is a difference with wiring. for the reverse lockout and reverse lights.
the t2 wiring for the tranny is about a foot longer, vs the na. easily correctable with a bit of wiring, solder, and heat shrink.
or, just dont bother, i never cared if my reverse lights came on when i was backing up

Would I run into any problems swapping out the splines on the driveshaft? replacing the U joint on my NA and taking the endpiece from the TII driveshaft and mating it with my NA? I can visually see the difference in size on the end of the transmission, but I can't really see any visual difference on the size of the U joint.

 

the driveshaft length is also different between NA and T2 iirc. either pick up a turbo to na driveshaft (or have one made) or buy a t2 rear diff and t2 halfshafts to complete the drivetrain swap (so if in the future you want to go turbo you will already be set). You will need to use the turbo starter/flywheel(240mm)/clutch(240mm)/clutch slave, these parts (including a trans) can typically run about 500 or so used (just picked up a drivetrain for my own project). OR you can 'trade' someone the turbo transmission for a good NA trans + cash and not have to change a thing (except getting a clutch of you already dont have one.)

Was there anything wrong with the transmission that came with your car? if not just reuse it with the 88 motor, also you will want to reuse all the electronics off your car on the 'new' to you engine (this means the wiring harness and injectors, the rest of the 88 parts are the same aside from the injector impedances).

Also, to add to the driveshaft debacle: The STOCK driveshafts are unservicable. You have to physically cut them apart to remove the U-joints.

 

The transmission is fine, it came with an Excedy clutch, and looked to be in good condition. The differential from the parts car however, is welded/locked, therefore not ideal for daily driving. I'll see what I can do.
