You could, but if your upgraded turbo doesn't have the same dimensions then you may need to get a modified pipe, a front-mounted intercooler may require an upgraded radiator, and if the intercooler adds a significant amount of power then the engine may run lean without the fuel and ECU upgrades.

Venom sucks. Use a reliable brand such as Denso, RC Engineering, Siemens, or Bosch.

I've heard they're just re-branded Denso's

Good to know! Thanks for the heads up. So what's the difference between low and high impedance injectors? Which do I need? And any of the companies you listed should be okay to buy?

I know the minimum injector size needed is 720cc but could I go to 750cc if need be? Just to open a few more options as I'm having a hard time finding 720cc injectors

Rotary Resurrection home of the budget rebuild.

Yes, as long as the fuel injectors have the correct dimensions, plug type, and impedance. If you want to make sure that you don't screw it up, just contact one of the vendors on this forum because they know what fits your engine.

Yes, you can use 750cc fuel injectors. Actually, a fuel injector that is rated at 750cc/min @ 43.5psi has just about the same theoretical output as a fuel injector that is rated at 720cc/min @ 40psi if your fuel rail pressure is 40psi in both cases.

I noticed boost creep not mentioned at all in this thread yet, Might be worth a notation. This is becoming the most civil upgrade thread I have seen in ages.

Yeah, everyone's been more than helpful

I know a little bit about boost creep, but what are you saying? You think I might get some with the setup people are suggesting? What could I do to combat it? Bigger wastegate? More free flowing exhaust? I have Racing Beat's TII turbo back exhaust and could take off the pre-silencer if need be
