i posted this in the tech forum too, but figured i might get some different answers here - i have an 85 prelude, 1.8, dual sidedraft, 3bbl - i have great low end power, but want top end power. i lose momentum and lots of power at 4000 rpms (with a red line of 6500, and an unknown rev limiter, if there is one - i can't get the rpm's that high). i don't want to put a lot of money into this car, but want to have the top end power. does anyone know how to get the top end power into this car?
