JoeAlex!
I got it modded to use that S54B32 motor that is included in the engine pack for 2.2.1...
It scripts properly, loads the engine with the car in the catalog. I also used the old E46 M3 pack's rims for the CSL, and BigBadassMotherfuckerBoss93's 3D tyres. It works perfectly in BB93's game. Can I send it to you, and maybe get it up?
Shot, awesome work my man!
