Don't use ANYTHING on the rotors unless you're planning on replacing your needle bearings. Anything you spray in there will eat away at the grease in the needle bearings.
Okay thank you but I have a 1995 Supercharger on mine and not the 1993. I have the 1993 pulley on it aswell. Is there really a big difference in 1993 to a 1995 pulley?

That's all very interesting. How are you managing the fact that your PCM has no idea what to do with the MAF sensor signal? Are you running an AFC controller? Something else? This isn't a 'bolt-on' swap by any stretch. Have you even scanned it to see how much is wrong?

I'm really not sure, the dealership is the one that has it all hooked up for me, it seems to run fine. I just wanted to change the intake gasket on but it did ran good.

seems odd for a dealer to make that type of mistake.....can we get a pic, just confirm

If they used the 93 TB, it would be ok-ish. I'd like to know what is going on with KR and fueling, though.

I will get some pics but I still dont know how to do that. Not sure if I'm doing it right but I've tried putting pics on here but I seem to have troubles and yes it is using the 1993 TB. just the supercharger itself is the 1995.

How can you be using a Gen2 TB on a Gen3 SC? The Gen2 TB is much smaller.... I am very perplexed... :?

I dont know, the Dealership is the one that did this and not sure how they did it but it looks the same to me.

Same bolt pattern. The coolant ports will be misaligned, and the diameter step is kinda severe causing turbulance.

Do you think maybe the dealership just took the parts off the 1995 and put into my 1993 case, like the front nose and rotors?
