hi hope someone can help i am doing a custom supercharger conversion for me celica and have some 630cc mrw injectors which i think are going to be to big. The car should be running between 200 and 240 at the wheels by the time the conversion is done, once the engine has been rebuilt i will be aiming for more. My question is will it be ok to put the 630cc injectors in for now i have been told by several people i will lose driveability is this true if so i will order some more from monkey wrench racing till i have the engine rebuilt
cheers
chris

its true once you get to large injectors idle quality and emission can suffer but im talking once over 1000cc

them ones will be fine as long as its mapped right
