Ok my friends N/a tranny is fucked. We have a dead TII but the trans and LSD are good. Are there any write-ups for this? If anyone could explain it to me I would appreciate it.

 

i think all you have to do is use the turbo II flywheel, but the N/A counterbalances.

 

If you had an aftermarket flywheel, you could use the na flywheel with the TII counter weight. Right?

 

Go to mazdatrix..as long as you use the same series parts, all the counterweights are the same regardless of n/a or turbo.

You'd just need a TII flywheel to use the TII trans and rear end.

 

ok one question are the TII and N/a clutches the same?

 

no...the clutches are different cause of the difference in the flywheel. It should be a simple swap. Just do the whole assebly, dont switch parts. Take out the whole NA drive train and put in the whole TII drive train and flywheel. I think you need the counterweight too though to keep the assebly balanced.

I wish i had a dead tii lying around. Im dying to switch out my drivetrain.

 

dont forget to take the anti sway bars too. TII bars are beefier. And might as well take the brake system if you can.

 

It is from a GXL the GXL already has beafy bars and brakes. DOesn't it?

 

TII's bars are still bigger. The brakes might be the same though.

 

How are the TII Flywheels different as opposed to na, besides the counterweight? ie. s4.

 

As for the s4, the TII and GXL share the same size In Sway Bars - Front 24mm Rear 14mm. Front Brakes 4 piston etc.

 

I think the flywheels differ in size. i dont know the exact difference but i know when you buy a clutch the TIIs is a differnet part # than the NA. Usually the 83-88 NA clutches are grouped together and then the TIIs are grouped together.

 

Did my post just get looked over, or am I reading yours wrong..all s4 counterweights are the same.

oh ya i forgot that its the eccentric shaft thats being counterbalenced

 

Yea...overlooked. My wrong. I guess I'm not used to your new avator.

Yes, the counterweights are same. That resolves that. But what are the physical differences within the 2 Flywheels? So It won't work, eh?

I might do a TII swap and want to findout If I can still use my RB Aluminum Flywheel.

 

Back to normal now, ahh..thank God.

If you have a n/a motor..and a TII drivetrain, you need to use the TII flywheel, if the RB flywheel is for a n/a, my assumption is it wont work, you need a flywheel for a TII to work with the TII trans.

 

Changed your avator again? From beauty to beast and now back again?

 

I'm a lover not a fighter...

 

Okay, so let me get this strait then...

I have heard some ppl say that the GXL is the same as an "N/A TII". how true is this?

I have an '86 GXL (last year before the TII was produced) and an '87 TII engine and tranny. I need to know if I am going to have to find a TII drivshaft, differentail, and half shafts for this car or not.

Anyone able to help me out here?

Thanks
Miles

 

The turbo2 uses a completely different tranny (Type-R baby ) Driveshaft, rear end and axles than the GXL. If you are swapping in the T2 engine and tranny, it is advisable to get the T2 driveshaft and rear end(with axles) also. You can use the N/A rear end, but it would require you to get a custom driveshaft made, as the N/A and T2 driveshafts are not the same length, and dont have the same bolting locations on the rear end (meaning the T2 driveshaft will not bolt to the pinion flange of an N/A rear end )

 

TII's have larger diameter flywheels and clutches. Also, the input shaft on the transmission is different. Put simply, Everything from(but not including) the engine to the hubs is different between TII and n/a.

 

...would it be a waiste of time, or even psychotic to have the drive shaft custom made for this project? I realize that the Turbo II rear end is prolly stronger. If so, then that prolly answers my question right there. I believe the ratio is the same, however.

like I said before, I already have the engine and tranny, and I know it's just not that simple (hence my questions)

All information/help is greatly appreciated.

 

I"m doing something similar. I am doing a TII swap and want to keep my 88 GTU rear end. I've herd a NA Auto drive shaft has the correct bolt configuratin but will BARELY fit in. I think it has to be lengthened like 2 inches. I'll find out in a couple weeks.

 

kewl. I saw your other post too. Looks like we should keep intouch, as we both seem to be on the same type of project at the same time. I know everyone likes to help out when they can, but sometimes it just seems like we don't have time to go back into our own archives to help someone reach what we already have, so those guys that just started end up having to fend for themselves anyway. (although, a few ppl on here have been VERY nice about answering my questions from their own expiriences *thanks*)
