Keep saving your money and buy quality parts. If you want to save money, do it with your FMIC kit. Ebay ones are generally fine. But most of those kits aren't going to come with everything you need, you have to setup your oil return lines and whatnot, and ebay kits usually don't satisfy a car that isn't setup for boost already. Plus considering engine managment and tuning, it adds up to be costly if you want to do it right. Take your time and try to find good used parts if your low on money.
