Does the buick riviera have the same m-90 supercharger than an ssei? say like a 1998 model? i was wondering because my friend is parting out his buick and i my just buy the charger if it is an m-90!

Thanks!
Bret

Yes, as long as they are both a series 2 M90.

where could i check that on it?

If they are both 98 then they are both series 2

if your car has a cover on it it will say 3800 series II

This is a series 2.
