Hello all,

I'm working on replacing my clutch in my car. My car is an 86 GX with a TII swap in it. I ordered an 86-91 Turbo clutch, but it doesnt fit. I talked to RX7Store.net (where I ordered my new clutch from) and they say that the correct part was shipped. So, I'm thinking that perhaps whoever built my car mislead me into thinking that I have a TII tranny, when really it's an NA tranny? Is this even possible?

Here are the dimensions of the parts:

Old Pressure Plate: 10.5"
Old Disk: 8.8"

New Pressure Plate: 11.5"
New Disk: 9.3"

Is it possible to determine the transmission from these dimensions?
I really want to know if I ordered the wrong part, or if I was sent the wrong part.

Thanks for any input,

Dan

 

Sorry dude, you have an NA tranny and clutch.

TII flywheel is bigger than the NA

 

You should be able to determine the type of transmission simply by looking at the body of the trans. The Turbo tranny looks different than a N/A trans. Do a search for threads with pictures and you will see the differences.

 

pics of na tranny are here

Well thanks for the input...

I guess that means that a NA tranny mounts up to a TII engine no problem then, right?

Anyone near Ontario or Manitoba that has a TII tranny for sale??

 

Are you sure you don't have some sort of NA conversion into Turbo? Your problem sounds really weird, unless you have an NA block and NA tranny...

 

Well to be honest, I'm not sure about anything anymore. I was told that I had a TII motor, with a TII tranny. The tranny part is clearly wrong now, maybe the motor is too. Would there be any way of determining this for sure?

If I were to pick up a TII Tranny, would it bolt right on? Would I need other parts (Im assuming a TII Flywheel, and others...)

Or... am I just effed over, and I have to buy an NA clutch and just go from there?

 

Dude, check out RPM, I just bought one and its awesome, the service is great too. Deal with confidence. They sell it for 200$ plus shipping.

EDIT: But you'll need to buy the flywheel, pressure plate and clutch for a Tii...The starter too.

let's go back a couple of steps...how does the turbo clutch not fit? Is it too big for the bellhousing of the tranny or does the spline of the NA tranny not fit (too loose) on the disk?
I'm pretty sure the engines, clutches and trannies (NA vs. TII) don't mate with each other...but then again, turboing an NA is quite involved. Take some pics of the turbo, intercooler, engine, tranny *driveshaft* *rear diff flange where driveshaft mates* so we can see your setup.

 

Alright, I will do that, but it may take me a day or so. Working long days out here at a fishing lodge...

 

Alright, I took some pictures, but the computer out here is so old, I cannot connect my camera to it. But, I think I have some information that may determine whether my motor/tranny are in fact NA, TII, or some odd half-breed.

I placed the new disk on my tranny, and the number of splines match, but the new disk is too big. There is maybe... 1/16 of an inch play? Maybe less. Enough so that you can spin the disk without turning the shaft.

If this is in fact an NA motor converted to turbo... This guy is going to be PISSED. Because he (me) was told (and paid for) that he had a TII motor and tranny put in.

But I digress.... First things first. Is it an NA or TII?

 

NA flywheels are smaller and have a raised ridge that runs just around the outside of the friction surface. Turbo flywheels are larger and don't have that ridge.

If you have a turbo engine and an NA flywheel - you have an NA drivetrain from the flywheel back.

 

So it's possible to have a TII engine, with an NA flywheel, then NA drive train?

 

Is there any way to look at a motor and be able to say "That's an NA converted to turbo, with an NA drivetrain" and "Thats a TII engine, must have an NA drivetrain some how."??

 

Yes, this is possible.
