800

[MR2Jedi]

800cc SARD injectors. The plug and play Supra injectors are 550cc.


What other Mods are you planning to do to reach your 400hp goal?..

Sounds good.
What turbo are you gonna use and how are you gonna control A/F ratio, ignition timing?
What fuel system mods are you planning on doing to support the upgraded turbo?

[90celicaGT2]

for the A/F ratio.. I have Greddy E-Management and as far as the fuel system I want do a full system upgrade and go with an walbro fuel pump, just and know what size I should get..???( any ideas...) I also have an upgraded fuel pressure regulator, and hi-flow gas filter.
