Few questions to ask, wondering if anyone could help me out. My buddy has an 03 cavalier 2.2 ls 5speed with: k&n cold air intake, pace setter header, borla cat-back exhaust, throttle body spacer, b&m short throw shifter, eibach 2" drop spring kit. Was wondering if anyone could give a good estimate on horsepower it might have right now and an estimate on what it would have if he put the gm performance supercharger on it. I know the only way to really know is a dyno but there is not one located near me so was wondering on a good rough estimate. Much appreciated the help
around 170-175, he basically has an intake and full exhaust and i dont think the spacer really does much at all i have heard.lowering springs and shifter do nothing bu yea i would say 170-175 good estimate because stock it comes 160, pacesetter header estimates 4-8 hp and intake exhaust maybe 5.
a friend of mine put the GM s/c kit on his 03 LS 5sp and got 220 hp to the wheels on the dyno.. thats with no other mods other then the kit.

Sorry alex but it doesn't work like that.
Each modification effects each modification. A modification can hurt you and help you depending on what you do. It's not like a counting game of Intake is 5 HP and Exhaust system is 10 HP and now you have 15 HP.
The only real way to tell how much power your friend is making is to tell him to take his car to the dyno.
By the way, the throttle body spacer he has on his car does squat on his car. It's more useful for carbeurated (sp?) engines.

2003 cavalier 2.2 ls 5speed has 160 hp before the mods? im tryiing to see if im reading it right. I tought cavaliers with ecotec had 140-145 hp?

They are 140 HP stock. I can't remember if it's 150 or 155 lbs of torque. This is what they are rated in the j-bodies, in the cobalts/ions/hhrs they say 145 HP.

I wasn't trying to diss you or put you down in any way. I was just correcting your statement.

its all good man, i just kind of came off that way
When chevy 86'd the cavy they did a big over haul for a replacement and came up with the cobalt along with they made the engine better quailty thus beefed up the ecu and other engine parts to give the ecotec a whopping 145hp 150Lbs torque. they wanted a engine that would out run the civic and toyata corolla. they knew that these cars where moving forward and needed to match or exceed there performance. with the cavy's engine power they could of not done this so they beefed it up. the cavilier had less horsepower. i know this because i blow cavy's off the road withmy cobalt(some had intake and exhaust) i have only intake. Now dont get me wrong the cavy engine rules and has alot of potential but cobalts engine is more pwerful.
ya know technically they are almost the same, i have a 02 cavalier ls with the 2.2l ecotec. but it also depends on which style cavalier you are talking about because there is the 2.2l and 2.4 so ya know. of course the cobalt has more horsepower though if it is the ss model with a supercharger. but just about your statement it depends on what cavalier you raced.i have raced a cobalt before with intake and exhaust and was head and head with it till about 80 and i started pullin a little bit. but hey there are both nice cars and i like them very much. if i got a cobalt i would have to do some definite mods to it though personally if it wasnt the ss. i think the regular cobalt looks to family like. so ya know either way i would take it.

Alex summed it up basically.

yes your right..i have plans to add mods because i didnt have my mommy to buy me my ss cobalt...but hey kudos to those that have one. Yes cavy and cobalts are nice cars both with a great engine thats why this site is called ecotecpower.com. so those of us out there with cobalts or cavy's lets unite and help each other out. thanks
