I've got an FD with a street ported 13B-REW and I plan on putting either a GT35R or a GT40R on it. The goal is to get 450-500rwhp. The car already has full exhaust and a Power FC.
Since the FD will be mainly for street use, I would like fast spool. Is there a big difference between the two mentioned turbo as far as spool goes? What would you recommend for me?
What other supporting upgrades do I need to do for that much power? For example, what fuel upgrades and intercooler do you suggest?
Sorry for asking so many questions, but I know you have tuned hundreds of cars and know what the best route is.
