i just built a a b20vtec combo.for drag racing

it will run with gt40r
bulit bottom end /stock poliched crank,cp pistons,crower rods,9,5:1cr/
built head/spring,retainers,valves,porting/


what is the optimum rev limit for it?

 

i think so also,but i dont think that 9500 or higher power can be safe...

 

crower springs/retainers,ferrera valves,valve guides,skunk turbo2 cams,or ctr,
