I would go ahead and get the 65# injectors.....they are only a few bucks more, and pay off in the end. what fuel pump do you have? I would upgrade automaticlly to a walboro, or Racetronix..... what cam do you have? what are your goals?
there are a lot of questions that need to be asked before picking the right turbo for you. I'd call Garret, Turbonetics, or Bullseye to get the proper MAP for your current configuration. they would be able to tell you which turbo would be optimum for you. all these universal kits....all do the same. give you a baseline bolt on.
