Yeah i know... i only get 3 port engines unless my track decides to start an outlaw class... but they do allow turbo plugs... so i might pick up a turbo head... at this point though... i just wanna get a modded engine... i cant decide if i wanna get something like this or get a jp mod... theres a local guy at my track that can get a JP moded RS12S3 for like 240-250... which is less than murnan sells his RS12S3 for... and they do alot of stuff... (and i really like the black crank case...) so what do you guys think? is it worth the extra money for an engine that doesnt have the extra stuff done to it like a jp mod?
