Stock Honda Fuel Pump

[zc vtec]

For any of you who don't know, I'm Sound Streamin's older brother. I too will be running a T3 turbo on my hatch, only I already have done my SOHC VTEC swap, and he's going to be doing his B18 swap in a few months. I'll get to the point.
How strong is the stock fuel pump on a 95 Civic? I know the stock injectors are 240cc, and I'm gonna upgrade to some DSM 390's as well as run a high flow fuel rail and an Apexi VAFC 2 for fuel mapping. I currently make roughly 126 hp at the wheels NA, and according to some calculations I've done I should be hitting around 170 with 8 psi. Can the stock pump handle that kind of power? Just like Streamin, I'll be getting internals for summer 2005 to run some killer boost and obviously I'll upgrade then, but for now, I just need to know if the stock pump is ok. If I need one now, meh, no big deal, I'll buy one. They're 85 bucks which is pocket change for turbo build ups. Any insight would be great.

dsm's are 450's. the pump, if in good condition, will handle the power, provided you dont use a fmu. higher fuel pressure is killer on pumps. if you use a hondata or other electronic fuel metering device, you mess with injector pulses and flow rates instead of fuel pressure. that being said, a higher flow pump certainly wouldnt hurt.

Some DSM injectors are 390cc's. These ones for example:

Most are 450 though.....

yea the autos are 390, but why not go wtih 450's? your also gonna need to modify your fuel rail a bit and you'll need some resistor clips to make them work.

no modification to the fuel rail is needed whatsoever....and get a resistor box from a 91ish crx si, instead of getting individual resistors. also, id get a bosch 255lbh fuel pump, thats what im doing.

i'm going to buy a 255lbh fuel pump as soon as i find a good deal on one. Ebay will probably have a few. It's a good idea to be safe with any forced induction set up, especially when it comes to fuel.
