Get a performance shop to do it for you, for how difficult it is, $150-$350 is actually pretty cheap labor for how difficult it is if you don't know how to do it, plus you could mess somthing up bad. Total cost will probably be around $500 with installation, but it will feel like you dropped a new motor into your car! One of the most worthwhile mods imo.
