Well how many miles, how are your compression numbers, how well did you and every owner take care of the car, all of those play a big role. You gave us no info to work on and asked a question. And bigger engine? You planning a 6cyl or V8? Hell save your time and money and put it all towards that if you are dead set on something bigger and just deal with the NA KA until that day comes. Otherwise you might not be able to save money because you are having to fix what you broke.
