You need to understand racing better to understand that you dont need an exotic custom turbo to be over your head. I would check the rally classified pages as it's infinitely less expensive and easier to buy a pre-built car. You may make the point that it is too easy to do it that way, but i can assure you that you will spend more than enough time fixing problems, messing with setup, and fine tuning the car to your taste. Also if possible talk to local rally participants if you can find some names and numbers online, ask them what a good beginner car is, and ask them if they know of any for sale, the way a car is prepared makes a difference, and they will know which cars are a good investment.
