3.25 pully?

hey guys,
i've looked a previous posts but they didn't really help me much cause i found conflicting info. i was wondering if given my mods below i could step down to a 3.25 pulley and if not what you would do to make it possible besides headers (don't have that kind of money). i don't know what my current knock level is...would the gm dealership or better yet some place cheaper like pep boys have a scanner that would work with my car?
thanx in advance!
da rev

nope.....you would need rockers or cam and headers or 3in down pipe and aftermarket PCM

Well, there's a guy in Calif. that has a couple more mods that you have, he says he runs one. Then there is a guy in St.louis that says he tried and couldn't.
I run a 3.4" on my GTX and I have more then the guy Calif. Everything I read says no you can't. The 3.25 will give you too many KR's.
I don't think you can, but you will hear from the rest of the "group" and hear all kind of things.
Good luck

thanks guys, u2 always know whats up!

It is very possible you COULD drop to a 3.25/3.2 and not have any KR if you get a good 3" downpipe ~$80 and a ported front manifold ~$80.

For a little more(but still less than headers) it is very possible you COULD drop to a 3.25/3.2 and not have any KR with the SS IC from www.zzperformance.com

The www.ls1m.com is a good cheap scanner.

thanks jeff i'll look into those...you've got me thinkin about an intercooler...probably be a while though...

You could always go w/ water injection instead of the intercooler.

I was supposed to install it on my car last night but my buddies SS IC install didnt go as smooth as I'd hoped.

I ran a 3.25 w/ just a tb spacer/cai/catback/xover wrapped/autolite104's. It pulled 7 Deg of KR but with race gas was good enough for 13.8's

If your going to start modding more and dropping pulley sizes then its really worth it to buy a scanner.

Autotap or LS1M are the 2 that I would suggest.
