What mods would be required in order to drop down to a 3.4" pulley? all i have right now is a k&n cold air intake

 

180 thermostat, headers or powerlog+downpipe, colder spark plugs, 1.9 modified rockers, a tune. Also a gauge to read Knock Retard so you know if you are safe on that 3.4 pulley.

 

1.9 rockers are needed to drop to 3.4? I am leaning more towards a cam. but I'd have to get new injectors huh? anyway I'd also add u-bend delete to chibi's list.

 

Headers and/or Downpipe remove the u-bend.

If you want to cam, go for it

 

Yea I guess you're right I forgot about that haha with the exception off speed daddy headers :/

 

I've been looking around for headers and I want to get ones that won't require a rediculous amount of labor hours, what headers should I get?

 

04SuperchargeR, they're all gonna take about the same amount of time to install...

SS Supercharged LA, you don't need new injectors until you drop to about a 3.2/3.1 pulley IIRC.

 

i have a 2004 Supercharged SS and i think that i already have a 180 thermostat but is that true? because im not positve

 

Stock is a 195. If your car warms up and sits in the middle of the temperature gauge, you have a 195.

You swap the injectors when you are tuning and the flow-rate is above 90%. If you aren't tuning yourself... I wouldn't really go lower than a 3.4

 

This means you don't have a scan tool. You NEED to pick one up, or you could very well blow that thing up changing pullies, if you don't scan after a pulley change and you have too much KR, you're gonna have a bad time.
