Look in the section of this forum marked FAQ. Then, find the section of it that says injector spreadsheet. Second post down

Hope this helps.

And keep in mind, that these numbers reflect 100% duty cycle on the injector, which isn't advised. You want about 80%, so calculate accordingly.

no . their only good for like 240hp's, and for ur hp's u also need a z32 maf.

With a new fuel pump and adjustable FPR you can crank the base fuel pressure to 50-55 lbs and that will give you another 20 or so hp worth of injector.

plenty of available sizes between 370 and 700. If 300whp is your goal 550cc injectors should work...

Or, 370's and alcohol injection.

I know of a set of 740cc Deatschwerks for 250 bucks on another 'unmentionable' site. I'll see what the deal is with them. I was going to get them for the heck of it, but if you need them, I'll give you dibs.

Nothing special about Nismo injectors except the extra high price for the name. Not saying they arnt nice, but an injector is a really simple thing that no company really has much of an edge on the other.

deastchwerks FTW! Awesome injectors and some great prices. Plus they give discounts for NICO members.

Main difference between injector brands and sizes is their "void time" which is the amount of time durring the pulswidth that the injector is opening and not yet sprayng fuel...it pertains mostly to idle opperation on larger injectors...but some brands have a longer void than others....doesnt make a huge difference but sometimes requires a little more adjustment for smoother idle.
