iirc stock injectors max out round 14psi

well, the amount of fuel being pushed out of the injectors will increase regardless of the boost right?

I think I know what you're saying but, the injectors will give the fuel according to how much the MAFS reads is going in and up until it can't give anymore. Just remember two different turbos at 14psi will be flowing two different amounts of air. Too much air and not enough fuel then makes a blown engine.

Well 370cc injectors will max out round 14, only way u can push abit more is with a nismo fuel regulator. Not that it would really matter much since T25/T28 maxes out round 16 psi.

You have a big 28? NO MORE THAN 8PSI!! That turbo flows a significantly higher volume of air at the same pressure as your stock t25.

You will be flowing a little bit more than stock due to the upgraded turbo freeing up some exhaust flow, but at stock 7psi you should be fine.

injector flow isn't dependent on boost. Just horsepower.

250hp is about max on the stock injectors with stock fuel pressure.

yeah, thats why i was wondering if this setup could max the stock injectors on stock boost
