I have an LQ4 with a TSP 228R cam and the plan is to run the FAST LSXRT intake and 102mm TB in an older muscle car.I will have 1 3/4 long tube headers.In searching I see the stock injectors are likely to small to be efficient.Harness ends not critical as I have not bought a harness yet. What is the flow rate that would be required for 400-450 hp.Is there a truck style injector that will work or would swapping to a set of different fuel rails allow me to run a passenger car injector such as an LS3.New to EFI so bare with me please.

 

Ls2 injectors fit in with no mods, you will just need uscar plugs. We have them in all sizes to 95lb.

The best deal is the short ls1 injectors for 239 a set
