Maximum Boost

[RacerBoi]

I know this question has probably been answered before but so has about 75% of the questions being asked... So no telling me to search or flames would be appreciated. I would just like to know what would be the maximum boost I could run with stock injectors on a KA with an intercooler. Thanks again.

You can run a little over 4 psi on stock injectors without doing anything.  And depending on how risky you wanna be, you can get way up there.  The highest I know of is someone running 9 psi on an RRFPR and walbro fuel pump.  I wouldn't do this, but that guy is happy with his setup.

hey jeff what have you done fuel wise, i see that you have the tial wastegate that is set at 6.5 psi, and dont see a boost controller on the list so are you running that on stock fuel?

Uhh those 3 things have nothing in common. He uses a spring set at 6.5 psi. Boost controller lets u run more than a spring, but u can never run less than that. And iirc he is running it on stock injectors and searching for sr 370cc ones.

Woot! &nbsp;He looked at my page!
Yea. &nbsp;I moved like 200 miles from home, have no job, live by myself, and am generally poor. &nbsp;So I haven't done anything fuel-wise. &nbsp;
Then I have a crunched front end that needs to be fixed, an auto tranny that needs to be put out of it's misery, and am a boostaholic. &nbsp;So I'm working on it.
But my system (untill summer) will either be:
a) afc and 370cc injectors, or
b) ecu reprogram (enjuku if I ever get around to calling them) and 370cc injectors.
