ceecookie SG the increase is based on the type of turbo...if u use those small/normal turbo u at at most 25-75 horses increase...while if u use a large Garrett T28 turbo i think it can get u about 100+ horses...
Sigmaprojects SG on hi performance motors most well built turbo kits will net you 60~100hp. And the way rotory motors are you can boost the hell out of them, just watch out for the oil, rotory motors eat oil.
boi86 SG the rx8 is power by 2 rotary engines, each of 654cc, thereby getting 1308cc. the jdm generates 250bhp, considering the sleek n executive looks it got, it's damn nice. price abt this car, i'm not sure abt tat.
