black_rude_lude

Im new to the fi method of tuning and want to do it properly. I own a jdm vtec 4 gen lude. Im looking to buy a spare engine a build it to run a reasonable amount of boost. I plan to buy pistons, rods and sleeves and then have someone build the engine for me. How much would this usually cost and would it be worth doint anything else at the same time??
Thanks in advance
