Turbos are your cheapest, best way to add more horsepower. Everything else is just additional. On a first gen I'd worry about the tranny output shaft before the lower end of the engine ... however DR500's maxed out on stage III heads will probably only hold 15-16psi to redline ... and should make close to 550-600 at the crank. Just look at matt's [email protected] ... stage III heads.92vr4ny said:DR500's
Stage 2 or Stage 3 Heads
... lets say 18 PSI?
Well I be maxing out the turbos? Can a stock, cast crank even hold this, if it is a 1st gen? If that is maxing it out, would the next option only be bigger turbos, or is there better ways to add HP at that point, like a CFDS?
