I want to modificate my RX7. What can I do for this?



I want to do it 600-650hp



Which parts do I need?

well, if its a non-turbo, swap in a turbo motor, then get a stand alone and a big ass turbo with all the plumbing and fuel system stuff to go with it, port the hell out of the motor and you could see that much,... of course then you'll probably break everey other drive train part in the car,.. so upgrade thoose too.
