Well I haven't found a single discussion for people modifying or upgradeing their sunfires, so I' figured I start one. I currently just have an AEM Cold Intake, but eventually I want to put a magnaflow exhaust on it, new headers, a Bomex body kit, mess around with the suspension, and then get the GM supercharger when it comes out. Any suggestoins or what others have done to there sunfires would be appreciated.

the block is stock bore, but with keith black forged pistons, $30 apiece. i guess the most expensive part on my car is the intake, which i bought from mantapart.com. it does away with the stock one piece unit-intake+throttle body-and allows you to replace the throttle body with a bigger one like mine. its off an '01 Z28. the intake is $250, or maybe a little more, but worth it! with a 2.5 inch exaust, and no cat, im pushing a dyno proven 205 hp, at 8psi. of course, the car is having some problems which are unrelated to these mods-i hope! i drove it for over a year with these mods and never had a problem! it runs a little lean, but other than that its fine. i also have accell coil packs, an msd im, accell wires and ngk iridium plugs, so it helps out. if i can fix the problems its having, i plan on finding a good set of fuel injectors and trading the stock PCM for a megasquirt unit which is fully programmable. im trying for 250 hp with less than $8000 invested. i know im pushing it! it may be possibe, and it helps that i did alot of the work myself! the only thing i didn't do was the head and exaust!
I am new to the forum and just thought I would say hey to everyone. I have a gold 2005 sunfire. It is slightly modified with 17" rims, 4 subwoofers with alpine deck and alpine 6x9's in the back, green led's under the dash and hood, green neons under the front and rear bumpers, rear tinted windows and a custom intake.

It is inappropriate and downright foolish to try to hop up a car with over 100,000 miles on it, that has an automatic transmission. This automatic was not designed to last much longer than 100,000 miles to begin with, let along to be used in racing; so as soon as you start putting more power through (or even often driving it aggressively); you'll blow the transmission.
If you can't afford to have a major unplanned expense wreck your life and educational plans; wake up and stop dreaming. Leave this car alone, or it will soon turn into a pile of abused junk. I speak from experience; after having destroyed every vehicle I owned when I was a youth; by hopping it up and driving it hard. Only after I got into a situation where I really had to have a car that I could depend on every day; did I learn to become mature and responsible enough to quit destroying the vehicles I owned by playing with them. I eventually realized that I was not rich enough to buy all the parts and make the constant repairs which are part of the everyday life of a hot rodder; so I then got into economy tuning. That finally was a place where I could modify my engines without damaging them (as long as I didn't set the mxture too lean; which is a constant temptation for inexperienced people who try economy tuning). So I then burned the valves out of some of my first cars in that era before I learned that lesson.
There are some unfortunate people on this site who feel the need to lie about the power and performance they have added to their cars. Be warned not to take all the claims seriously about gobs of horsepower which you read here.
