Well, I just got back from General Rapists....I mean Motors...

Seems my supercharger coupler is in fact kaput...not a big deal. But of course GM doesn't sell the parts seperately. So where do I get a new coupler (and smaller pulley )? On top of that, is the procedure for changing the coupler posted somewhere? How big of a job is it? Is the pulley press fit onto the coupler or just bolted on?

Second, I am intending to replace my O2 sensor...except GM wants $111.38 for one. Of course, the service manager informed me I should "Stick with a GM one, everything else is ****." Please tell me there are some REASONABLY priced alternatives (as I'm sure there are, as GM seems apt to screw me).

Thanks in advance guys.

i think that both of your questions are answered in Techinfo

Coupler from www.zzperformance.com
O2 sensor from www.gmpartsdirect.com for half that price, and the dealer is correct. Everything else is ****, with the POSSIBLE exception of NGK.

Wow, kudos to the dealer, first time they haven't tried to pull crap on me.

Thanks guys.

They pulled a crappy price on you
Get the coupler and the other goodies in the sticky at the top of the Forced Induction forum, and we'll walk you through the work when you get it. It'* fun, fairly easy, and can be done in a day. You'll actually enjoy it, I think.

Oh I have fun doing pretty much anything mechanical...used to be an aircraft mechanic so anything mechanical makes me happy...lol

Off topic, but what aircraft? CH53-E and RF-4B for me.

ok on the topic of pulleys? exhaust ad intake and (thats about it for me) what should i look for on ZZP to get for a pulley?

2.5 should be good, you have a 2.8 on there now

They're our preferred Series 1 pulley source.
