I have a JDM ZC Vtec engine in my 93 hatch and im going to start buying parts for a turbo buildup but im on a bit of a tight budget. Im only looking to make about 10psi max. What is a decent turbo to buy??? should i buy one from a wrecking yard or is that a bad idea??? also what size?? this is my first turbo buildup so i'll need all the help i can get!!
