I have wanted to put a turbo on my non turbo rx7 but i want to know if i should just buy a turbo 7 and just rebuild it. I have 3 grand and i want to put a turbo on my car. Should i get another 7 or should i stick with the one i have. The one i have right now is clean and the engine is in great shape and has 34,000 miles on it. which is the best idea?

 

Unless you are familiar with auxiliary injection then trying to make power out of a turboed N/A will almost certainly result in a blown engine. If you only want the little added horses and don't plan on seriously modding the engine then you could put a turbo on your N/A but it is generally not recommended. If you can afford a TII it is a more reliable and logical choice.
