I was wondering if anyone could tell me where to get a supercharger rebuild kit. It'* making the clanking/rattling noise and I don't know where to find a legit kit to make it better. I have a 97 SSEi with 170000 miles on it. I have a 3.5 inch pulley with a zzp pcm. K/N air intake system. I'm slowly working on the mods and I was wondering if anyone could tell me if I can get a downpipe for the stock exhaust manifold. And if it would help with throttle response. I have a good catalytic converter on there now but I'd like to upgrade that in one go as well. Any input is greatly appreciated... Thanks

Here are the needed parts for the M90 rebuid.

They also have downpipes too.

From what your saying it sounds like you have a bad coupler.

Dan, isn't the sound of marbles in a can the symptom of bearings going?

Nope. That'* a bad coupler.

Duly noted, thanks Roy.

Best way to tell is remove the belt and twist the pulley back and forth. You should feel the slop. But every time I hear the marbles in a box sound, it'* the coupler.

Ahhh, gotchya! So the marble sound is the coupler play then.

Do bad bearings have any indications?

More of a grinding sound.

Thanks for all the input guys. I really appreciate it.
