Hello. Wondering if anyone would know if a VG33E (normally aspirated - N/A) engine block will operate properly with supercharger? My son rolled his 2003 xterra auto (low kms and still runs well) that has a VG33E. The body is a write off. I found 2003 xterra auto, supercharged and perfect body that needs an engine. I was thinking of removing the VG33E long block out of the totaled vehicle and put it into the supercharged vehicle (VG33ER). I've read on other forums information about the two different types having different compression and that there are different pistons in the VG33ER block. Would I have to replace the pistons or is the compression thing not that critical?
