I am just finishing building a Boosted B16a2 build, i want to run around 15psi of boost on my set up-

*JE forged pistons 8.5 compression and eagle rods
*ARP bolts all round
*OEM 0.4 headgasket
*T04e (.57 trim and .63 a/r)
*2.5" charge piping
*3" downpipe
*RC 440 injectors
*Mapped with crome

Will i need more to run this amount of boost, like bigger fuel pump, bigger injectors, and a 3 bar map sensor?

You will need larger injectors (at least 550's, probably more), a larger fuel pump (Walbro 255lph should suffice), and a 3 bar MAP.

Everything i expected then, damn!

So out of interest, untill i get those parts whats the most boost i can run??

Provocateur

Depending on how much fuel pressure and duty cycle you are running, you can run up to ~12 psi on the stock MAP sensor, but I wouldn't run that much without at least upgrading the fuel pump.

Ok thanks for the info.

do you have a fpr if not only run 7-8 ish until u get a new pump, ur stocker will die if turned up to much.
