i just bought a 2003 bonneville ssei and was wondering what would be the best mods i could do to it. what size pulley is the best to put on there. what i wanted to do was get a cold air intake, 180 stat, smaller pulley but im not sure what size to get, and a performance chip but im not sure where to get one of what to get. when i do get a pulley, do i need to get a different belt or what and how do i know what one to get. any help would be appreciated. this is the first supercharged car i have had so i dont know much about it.

3.4 pulley, 180* stat, CAI....Free up the exaust flow a bit, and DHP 1.0 PCM.

Should be a pretty bad ***'d combo right there. Depends on how hardcore you wanna do. I think 3.4 is the smallest you can run with out cam, rockers, and IC.

Intense and DHP both offer PCM'* for your car.

Check the Techinfo link at the top of the page, as well as LINKS.

PCM'* are great for controling KR. I think they make the high speed fan kick on @ 185*.

Not to be a total newbie, but what exactly is KR? I've read about it in a coupla forums, but I don't know what it is....
