If you are planning a swap and turbo setup, i wouldn't recomend the crvtec, I would either drop in a B16a or a B18c1. I am not sure if anyone makes a turbo kit for the crvtec, but any bseries turbo setup might work, but not sure. Check out this website, and maybe give them a call or drop them an email, I am sure that they can help with your crvtec, if that is your route.
