Hey just wondering if anyone knows if there are any pre-built engines out there that can be purchased for a 97 cavalier. Does GM sell any? thanks alot!
i think Jbodyperformance has them

Im a Xbox 360 fanboy...and damn proud of it!!
2.4 or 2200?? what are you looking for, and what are you looking to spend?
HP Tuners | Garrett T3/T04B | 2.5" Charge Pipes | 2.5" Downpipe | 650 Injectors | HO Manifold | Addco front/rear | Motor Mounts | HKS SSQV | Spec stage 3 | AEM UEGO Wideband | Team Green LSD | FMIC | 2.3 cams | 2.3 oil pump swap | 280WHP | Now ECOTECED
right now i have a 2.2. with 121k . I have always wanted to do a 2.4 swap and figured with the miles getting a little high on the 2.2 i should start looking into my options. I figured if i could find a 2.4 that is already built it would speed the process up. I would be looking to spend between 2-4k on it, depending on the specs.
Check with Pace Performance, Scoggin Dickey or any GM dealer they sell GM remanufactored 2.4 engines for around $2400 + shipping.
2000 Z24 5spd header & catback for now.
