How much boost can you run on a B16A2 with stock internals. The fuel set up is a 255cc hi-flow pump with modified 450cc DSM injectors. Using the V-AFC hack for fuel management.

 

35 psi should be good.

Ok, but seriously it all depends on how well it is tuned. I would say with a butt dyno 10-12 psi is more than safe. Any more than that would require a good tune with a dyno and a wideband.

How exactly are the injectors modified?

there DSM injectors modified to be used in a honda civic. The DSM injecotrs are saturated injectors but my civic uses peak hold. I wired a 10 ohm, 10 watt resistor inline to convert them.

 

What kind of injectors? I thought all DSM injectors were peak and hold?

all dsm injectors ARE peak and hold, and unless your civic is obd0, than your injectors are saturated. i think you just had it backwards
