![]() I still have stock 19 lbs. and a stock maf so i figure i should upgrade at the same time. The question is what size injector should i get? I havnt had it on a dyno but i have to be pushing 300 rwhp and i am ordering a systemax or Rpm2 and have future plans of either a supercharger or the new Edelbrock plate system nitrous kit for the RPM 2 intake. The fuel injector calculator on this site says that i should have larger injectors already. Are my injectors holding it back any? It doesnt seem to starve for fuel.
Ford sells 2 sets of injectors, one matched set and one not. Does it make much of a difference? Is so ill go with the matched ones because i get a really good deal on motorsport parts through my work. Thanks for the help

![]() That's good the 19's have gotten you this far. With adding the new intake 24's would do, but your going to need 30's/36's when you add boost/nitrous. Depends on the amount of boost/nitrous really, but I don't want you to under cut the fuel supply. Putting in 36's now with the stock ECM controller might run a little on the rich side, but can be helped with some tuning. However I would go with the matched set of injectors, they will give you better performance. I'd say to decide on either supercharging or nitrous before ordering a MAF meter. If your going to run boost get a Pro-M Blow Thru meter (75-80mm). If nitrous you could get a standard meter.

![]() how much horsepower or what 1/4 times will i be capable with the 30 lbs. Can you go too big as long as the maf sensor is calibrated? I rather not have to buy new injectors again after a power adder.
thanks for the help

![]() If you can send me an email address I can send you a cool little stand alone program that I think will help you out, it's only about 108KB. I've put 36's in cars, you just have to find a happy medium with the fuel pressure, normally yes the MAF being calibrated for the size helps alot.
