Which starter must I use? S4, S5 TII, N/A
Hi,
I have a 1991 Convertible. It had a bad motor in it. I bought a 1988 N/A motor to install.
I pulled the motor out of the car and found someone did a TII swap originally on the car. The car came with N/A intakes, but had a TII transmission and a TII core motor block.
After putting it all back together with the S5 Clutch and S4 flywheel/Pressure plate, the starter just spins. I am pretty certain that the solenoid is working and pushing the gear out to engage because the starter would not spin if it didn't due to the safety interlock, right??. I pulled the starter off and on the bench it works just fine. With power to the terminal, the only time the motor spins is when the solenoid engages the starter gear.
I used the 1988 N/A flywheel to match with the engine internals.
Basically I went from an S5 TII to an S4 N/A swap. I still retain the S5 TII tranny.
What do I need to do for a starter? I originally thought they were all the same and interchangeable. Are they or are they not?
All help is appreciated.
Thanks,
Tim

OK,
I just took a nosecone off of a bad starter and installed it into the mount and the flywheel gear is nowhere near the starter gear. What is the quickest and cheapest solution to this problem. Do I need to install an S4 TII flywheel? Are they the same weight and balance for the N/A and TII internals? I assume the pressure plates are different also, so do I need an S4 TII pressure plate or can I just use the S5 TII pressure plate?
Thanks

Thanks for the confirmation. This was what I was thinking after checking the starter nose cone with the transmission and flywheel.
Does anyone know how much an S4 and S5 flywheel weighs. I thought one was 19# and the other 23#, but not sure. I want to weigh the S5(?) TII flywheel that I currently have to confirm it is the wrong one.
Thanks,
Tim
