Default Injectors

What injectors are you running on your F/I lt1. Also how much boost are you running and what are your hp #'s.

I guess more to the point, what are you planning on doing. All applications have diff requirements, hp level is a factor as well.

I would direct you toward a calculator.

I maxed 42# injectors on a stock motor with 10psi and the Walbro 255 in-tank pump. Car was S.C.'d though, so the bsfc was lower than a turbo motor would be at. So, I think you'd be pushing it going that route.

Get the Mototron 60# injectors (biggest high z available) so you have room to grow when needed. They still idle pretty nicely in that size as well. Mototron 60's would be taxing a single 255lph pump when they get around 75% duty cycle though. A racetronix twin in-tank setup should solve that problem.
