s30red240z Posted December 2, 2011 Share Posted December 2, 2011 what kind of injection system do you have?, year, turbo, non turbo? Quote Link to comment Share on other sites More sharing options...
Challenger Posted December 2, 2011 Share Posted December 2, 2011 (edited) With stock electronics the computer wont know that you've increased the injector size and you'll be adding more fuel at every running condition not just where you are trying to make power.

Cannonball89 Posted December 2, 2011 Share Posted December 2, 2011 What have you done to your car to require you to need bigger injectors? If your car is stock then bigger injectors aren't going to get you any power. Quote Link to comment Share on other sites More sharing options...
s30red240z Posted December 3, 2011 Share Posted December 3, 2011 If you have a vg30et twin turbo, and if you feed the AFM with only one turbo you can put double size injectors. example 520cc injectors. i think! Quote Link to comment Share on other sites More sharing options...
billyssp Posted December 3, 2011 Author Share Posted December 3, 2011 It's a 81 turbo with t3/t04e, 3in exhaust, intercooler, 60mm tb and 2mm hks head gasket... The fuel system is 1/2 feed and 3/8 return with an accel dfi pump. I had a haltech f3 and it went bad so i need to run the stock turbo harness and computer. So the mustang 720cc injectors wont work with the stock turbo computer. But i do have mustang 30lb injectors (red tops) that i need to use for now. I dont want to use any hobbs switches on the zx. And i will bring the boost down to 14 to 15 from 20 psi.Thanks Quote Link to comment Share on other sites More sharing options...
Tony D Posted December 3, 2011 Share Posted December 3, 2011 I'd drop it more than that... Quote Link to comment Share on other sites More sharing options...
