john, scrap the mafs idea… it’s a waste… go AEM w/ MAP and have it tuned by Dan or Sasha. if you arlready have the PFC go to D-jet.
Z32 MAFS is sooo 2005.
also, buying used injectors is slightly silly as well. I beleive theo got rooked doing that. you cant tell what the flow rate is and you cannot diagnose problems with them by eye in many cases. It’s like buying a used Garret BB turbo. spend a couple hundred bucks extra and get peice of mind and a warranty.
