I am going to build a head for my b18b and am compiling a list of things I'll need. I plan on using crower 403's w/ full valve train of course, a mild PnP, and am going to use a blox intake manifold, and tuning w/ hondata or chrome. Question is will my stock injectors handle these mods or would I benifit from larger injectors, and if so what size would be best. Also already have all the basic bolt ons.

 

hey ur injectors are fine with that setup but in the near future get some bigger injectors when you can afford them

 

I have an LS with almost identical mods, stock injectors are more than adequate.

 

Stock injectors are 240 CC's I believe so how much HP can these support.

 

180 whp without difficulty.

 

Is there any to increase fuel delivery from stock fuel injectors with just a custom prom basemap or is tuning needed to increase fuel delivery. Cause right now all i have is a chipped ecu with custom prom from phearable (mtber) until i can get a tune, but my car is running lean. Adjustable FPR is at 55 psi.

Are you using a wideband?

 

Would I need an adjustable FPR for tuning or to make things work correctly or is that not neccissary.

 

No, just an aftermarket faze a/f ratio gauge. But before cams and skunk2 intake manifold install, gauge was at ideal, at the halfway mark on the top of the gauge, now after mods, guage marks just a little under lean about 1/4 way up on the gauge.

Not necessary with Crome or Hondata, not with your setup. If your injectors were not enough for the amount of power that you were making, dialing up the fuel pressure would be a band-aid to temporarily 'fix' the problem.

If that gauge is using the stock O2 sensor, it's not a reliable indicator of your A/F.

 

Also, before cams were installed, spark plugs were brownish red, now after cams and i/m install brand new plugs are coated white. Timing was advanced 1 degree, is that too much?

 

The simple answer to your problem is to get the thing to a dyno and tune it. Crome is free.
