Fuel System setup for 4agte

[cri_ag]

toyota 3SGTE has 550CC injectors (iirc).. probably aroudn $130-150 each?

$160 for a new injector is not obscene... considering the importance of the part in the performance (and life!) of your engine

umm arnt 3sgte side feeds? i think he is using a 16v head so they are usless.

i use rx7 550cc injectors, bosch 910 pump, bigger fuel lines, stock reg. enough for the 4a to make 306hp at the wheels

ST215 caldina's use 525cc high impedance topfeeds, they look just like sard 550's

I've used them in a turbocharged 1zzfe.

Would go the in tank Walbro if I was to go again.

4AGTE, factory pressure reg (100kw reg so higher base pressure than bigport/gze motors), new 8mm feed lines, 1/4" factory return line, 165rwkw on 13PSI, 440cc 7mgte injectors, R33 GTR pump shoehorned into EFI AE86 tank. No surge on the track but never run less than 1/4 tank.

this. they are the skinny format too..

plus they are split spray rather than single shot (rx7 are single shot no?)

[cri_ag]

yep rx7 are single shot, well mine are anyway.

[dangdang]

Twin shot sounds the goods, one each straight down on top of each inlet valve

Sorry to revive an old thread, but I am curious to know if a high flow pump like the Supra twin turbo, will over power the stock pressure regulator. I am currently getting 55psi line pressure with 550's and Supra pump. Going to swap out another pressure regulator, but if the pressure is still this high at the rail then I am forced to get an afpr. Curious to know if anyone has experienced this.

Thanks,
Ron
