My RX had a engine swap from NA to TII, I am planning to replace the Pressure plate and the clutch, maybe flywheel.
Here is the problem I went under the car and the Gearbox seems to be the NA, So when is time to order the parts, do I order the pressure plate and Disc set to match the gear box (N/A) or to match the Engine (TII S4)?

If I want to install lightweight flywheel do I buy the Turbo or NA?

I also found a tiny crack on the flywheel its very very small, its right on the area where there is friction with the clutch Ill post pictures as soon as I get home. but anyway would this be a problem?

Just want to double check since the shipping to CR would take like 2 weeks, would not like to get the wrong parts.

According to this it should match the gearbox......................

Can I install the Turbo II transmission into an NA?

Certainly. But you need to also install:
-TII flywheel, clutch, pressure plate
-TII slave cylinder
-TII starter
-TII driveshaft, differential, axels
-Adapt the wiring.

You're right, clutch matches the trans.

 

thanks for confirming, what about the flywheel? do I need to use NA? besides that, do I need to change the counterweight if I go with lighweight flywheel?

Here is the picture of the flywheel, they are very small cracks, should I resurface the flywheel? or do i need to replace it?

thanks

 

The transmission is NA, so both the flywheel and clutch must also be NA. Turbos use a larger diameter flywheel that will not work with the NA transmission.

 

You will want to resurface the flywheel anyway for a proper clutch job. If the scratches are minor after the resurface you will have no problems.

If you do go with a lightweight flywheel you will need to purchase an automatic rear counterweight that matches your series engine to use as your counterweight.
