Just wanted to introduce myself. I own a '02 Cavalier 2.2 and a '00 Sonoma 2.2. The Cavalier is my daily driver and as of right now I dump most of my money into the Sonoma. I never really thought about doing any mods to the Cavalier, but I know they can look nice when done right. I never knew they made a supercharger for the Cavalier into a few days ago. So if I dont do any mods, ill be on here for maintenance stuff.

yes there are two 2.2L engines that came in j-bodys there was the
ln2 to start with that looks like this

and then also there is an ecotec or l61 wich looks like this

this should help you find out what engine you have

yeah ... which engine do you have in your 02... is it the same as the sonoma engine.... if so... there isn't a super charger for your motor... if its the ecotec, then there is

More info needed !
