Are 4 x 625cc injectors large enough for a 13B PP?
As above. I've built the engine primarily for drag racing although it'll be street driven also and should be making 300 - 320hp. Max rpm will be 10,500. Throttle body is a 50mm TWM item with 4 injector pockets and ECU is an older Haltech fuel only.
I can get 4 x 625cc Siemens injectors but I'm not sure if they'll be large enough for the expected hp and rpm. This is my first injected pp so I'm a little unsure on injector sizing and don't want to go too big if I don't need to.
Can anyone help?
