Hey, welcome to the board. To answer your question, if you want to put a b-series head w/ vtec on your motor, you will have to sacrifice some compression in order to run a turbo. this will cut down on your power when you aren't in the turbo's powerband. If you purchased a junkyard turbo, such as one off an eclipse, you'll want to have it inspected and possibly rebuilt. As long as you are willing to pay for a little machine/fabrication work, you should be able to make almost any turbo work...except for the turbos off of the new evo's and SRT-4's. the evo's spins a different direction, making the setup too complex to mess with, and the SRT-4's is just stupid b/c of the design. if you are just going to run low (4-6lbs) boost, a remapped ecu or a plug and play design will do fine. If you are looking for higher boost apps, you'll need programmable and tunable engine management. you'll also need to upgrade a lot of your internals to handle the stress of boost.
