i need some help does anyone know if the cobalt ss supercharger will bolt up to an ecotec motor.and would you need to do any other modificationsnull
it will fit, but you need to make a modified plate to connect the throtle body, because the colbalt one its not the same as the cavaliers

I did a little searching for you........you need to thank airtonics since he was the first to do it as far as I know. Yours might be different since his is an 02.......we got the weird year for the ecotec.
