i have a 03 cavalier and it would be helpful to know how i can get a lot of horsepower with out boost? if i got a supercharger and intercooler would my engine be able to handle it? or would i have to get some internal stuff?
an s/c is boost, sorry to burst your bubble, haha. if you want alot of power, i'd suggest either getting nos (and i'd suggest some engine work for that) or going n/a with alot of internal work. but no matter what, you're going to have to do extensive internal engine work if you want alot of horsepower.
Blown.
No matter SC or turbo an eco can reliably hold 250WHP stock. Keep in mind that's with a good tune. The life of a motor depends on how well it's tuned, for the most part, and not exceeding what the stock setup is capable of. GM says our rods snap at 278hp, but it was never clarifed if that's crank or wheel hp.

that was on nitrous, and there is 4 or 5 people with more whp then that now on boost.. and for a while I think its higher

eh you can get plenty of power without boost... but it's going to be with nitrous. not n/a. sorry.
I was a retard, and now I'm permanently banned.
^^^thanks spotabee. figured i'd take a shot at it. but i know that n/a cars can get good power, hopefully i'm not wrong in saying that.
Blown.
its certainly possible

richard, how much experience do you have with cars and auto upgrades in general? i'm not trying to be an a$$, so i hope i don't come off that way. i'm just curious.
and if you're serious about modding your car, read the Full Ecotec Build Guide in the performance forum. adam (aka NJHK Sexual Chocolate) wrote it and it has alot of things in there to help you get started. also, ask, SEARCH, and research as much info as you can before you touch your car (and thats if you're a newb or a veteran).
Blown.
go with boost you wont be dissapointed..... just do your homework and spend more money than you think you need to on fuel and and air/fuel ratio reading setup and you'll be cool.....

the engine from another dimension
Also, I sure wouldn't want to bore an Ecotec .040" over for the heck of it...

Now, I'm curious, why would you put this in the BOOST forum?
