I have a forged Nissan redtop sr20 det , with Tomei poncams . It has a garrett g25-550 turbo, and makes 400bhp at the flywheel about 18psi . Im interested to know if I could fit a bentcam head with vct , would this be worth any gain in the mid range,or would I be better to fit a better redtop camshafts, with the valvetrain to suit.
