well i have a few questions for every one. i am looking for around 330 to 350 hp to the wheels and wanted to know what combo if injector cc's would get me close to that goal. its on a T2 street ported engine with a BNR stage 2 turbo will be run by a haltech E6K

and i also plan on installing a cooling mist kit i am undecided at the moment on weather to run jest water or a H2O/meth mix. another question i have is roughly how much power can the stock fuel system take i do plan on upgrading the pump but is there anything els i may need ?

tradiational combo would be something like 4x720's, thats enough to do 350, but its pretty maxed out

in the last few years you can get bigger drop in injectors, so something like 550x1000 or 550x1200 would be good too

stock fuel system is good for like 240ish

my personal preference would be to do just straight water, i dont like the idea of having a plastic tank of fuel in the car with me.... seems like a little water works great

Surge tank.

Bosch 044 Fuel tank.

4X900cc injectors.

Will easily cover 350hp and any future mods up to 400-420hp. But more importantly, its a fuel system, so over kill is the key and with the above at 350hp youll be running 65-70% injector duty cycle.
