If I were you I would start with a very well and heavily built 6 bolt engine, and as much as you don’t like it, you are going to have to get new springs, valves, cams; well lets just say you will need a heavily built head as well. Also as the members were saying, you are going to need a big big turbo, big injectors, big money, some type of crazy fuel setup, DSMlink(or your choice of management),clutch, flywheel, stiff ass suspention, and some other things I am forgetting. Then when you get the whole thing set up in you car and the engine and clutch is all broken in, you will probably launch it, then find out you need new axles, built transmition, and some big ass tires(with 600hp, even all wheel drive spin out), getting to 600hp is allot of work, time, education, and most of all money, and if you are looking to get 600hp, you might as well buy a car with 600hp. You will probably end up spending less money that way. Either way, good luck to you in you adventure to 600hp.
