Injector sizing
I recently wrapped up a head (CNC ported GM 243) and cam (228/232-112lsa) swap on a 2004 LQ4 that I've swapped into my 70 GMC and have been looking at swapping injectors. I've used several of the online calculators for sizing, but haven't come across any concrete information. I'm estimating my hp at the crank between 450-500. The direct swap route would be to swap in the 8.1L injectors that flow 36 lbs at 58psi. I could also swap the marine 8.1L injectors that flow 42 lbs at 58 psi. I've also been told I can swap injectors from an LS2 with new lower O-rings and different connectors. I'm still using the truck intake and fuel rails for now also. What are others using in similar situations? I'm open to any suggestions. Thanks!
