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.

i've got a 96 2.2, and i've done more than a little work. its all budget, so don't laugh. i installed a stock turbo from a 98 gsx eclipse, and a hks boost controller, all of which cost me around $350. i welded the header myself , and its got about $60 worth of 1.5" exoust tbe, and a piece of 1/4" thick plate steel for the flanges. i had my haed built with .190 valves, and ported and polished for $300. The block has eagle rods and wrist pins, which set me back $250, and a mantapart.com cam which was a little over $200. 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! |

hey what up just picked up a 99 coupe,, havent done anything on it yet, its an 2.2L automatic with 95000 miles on it. im planning on doing several mods to it,,, my inquiry was, has anyone actually done any upgrades or modifications the the internal engine and /or transmission. the only thing in scared of is adding all of these modifications and having the engine or tranny die out on me... what i was going to staro off with was a borla exhaust system along w/a hi flow cat and performance headers, AEM CAI, rims, suspension. evemtually i want add a turbo and intercooler.. let me know what u guy's think please!!

Hello, 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. |
