Just purchased a 2004 cavalier w/ the 2.2 ecotec and need the run down on available parts for the engine if someone would be so kind. I'm new to this engine and need some direction. Thanks.

You're in luck, the ECOTEC has lots of factory support and a better overall design than the LD9 and can support more horsepower with more stock parts than the LD9.

There's what they have to offer so far, and should be plenty to make a 300+HP streetable engine (with some forced induction, of course)

i have the ecotec too strong little 4 cylinder bolt on stuff i think is the way to go check out rksport.com rswerks.com rsmracing.com highrevmotorsports.com pfyc.com all bolt on mod`s and not that costly either
