Hey im here.... You just cant go and fit a supercharger to a 18rg/18rgeu. You need to rebuild the engine for the supercharger so it gives the best compression for the supercharger. Ive got a 1GGZE a 2 litre superchager going in my beast, and A/C brakets is the way to go. But its still geting rebuilt, befor i work out how to fit the thing
