Yeah it took me two days to completely paint the calipers. From when the car was used to the time I was able to use it again. Just make sure you get them to bare metal and use brake cleaner to get 100% of the dust and grease off.
If it's got headers, check what pulley is has on the supercharger. Sometimes people unsafely mod the 3.8 and you wouldn't want to have excessive kr.
I've got the N/A 3.8, It had plenty of power for me at first, but I'm now realizing the high end power is kind of lacking. It's plenty fast off the line though. I'm sure the S/C 3.8's are just fine at higher rpms, especially with headers. Who knows, maybe that will be my next car, I love my Grand Prix in every other way so far.
