Well guys i went to the track yesterday and ran the supra a lot. After i got home i pulled into the garage and let it idle and listened to the motor. I noticed a slight knock. I had a fresh rebuild a year ago maybe with close to 10k miles on it because i dont drive the supra that often. So anyways what im tryin to get at is if the problem is rod knock should i rebuild the motor agian or get a low mile jdm motor and build it. I want to build a motor that will withstand some horsepower with out haveing to worry about breakin anything internally. Let me know what u guys think thanks.
