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??

 

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.

 

Thanks for the info, i will invest in a new fuel pump. i will get a walbro 255.

 

make sure to get the hp version

 

I didnt realise ther were any differant versions but i then again i havent researched them yet, i will make sure to buy the HP version thought, thanks again. ste
