How much horsepower does the turbochargers at Cavalierconnection.com give out? I was planning on getting one soon for my car? Does anyone know where to get an 2002-2003 Ecotec motor from and would it fit in my 2001 Cavalier?

the turbo kit from there at 6-7psi would give you 40-50% of you're original h/p. 2.2L ecotecs are hard to come by b/c they're prety new. check junk yards for the best buy, and yea it would fit w/ some modification (i.e. motor mounts, ecotec transmission, ecu, etc...).
