YOU HAVE to upgrade the fuel system. Let me guess an Ebay turbo kit for like $1,000. Look people when are you going to realize you get what you pay for? Now you need to find the missing link for your MAP sensor, a boost timing master to retard your timing according to the boost, larger injectors, a fuel injector driver or a fuel controller, upgraded fuel pump, and someone to program the fuel system. Now that you have spent another $3,000 wouldnt it have been cheaper just to get a kit like Greddy, or Turbonetics?
