pjecthatch, 1st off WELCOME ABOARD!!! In regards to your question, I'm in southern cali (LBC) to be exact. Just to hone your 4 banger shouldn't cost more than $70. It usually runs around $15 a cylinder depending on the competition of the shops. If you're planning to go turbo, I'd suggest you have your blueprint ready before starting, otherwise you're gonna have to do everything twice depending on how much you want to boost. See if you can pick an engine and what set up you want to run, then everyone would probably be able to assist you better. Good luck!
