Fuel rail won't help. Basically the only things those are good for are pushing huge injectors and for making the engine look more colorful. The stock rail should be good for around 400 HP or more. Get the fuel pump, it should be mandatory. FPR will help you regulate the fuel pressure better, but I've yet to hear ONLY positives about the AEM FPRs and their diaphrams, etc. Larger injectors has been covered before. An Ignition would be okay, but some of us agree that the stock ignition is more than adequate provided your plugs are gapped correctly and some of us have seen cars with aftermarket ignitions where they have had nothing but problems with them.RaceInspired said:How would a performance fuel delivery system (fuel rail, fuel pump, and fuel pressure regulator, larger injectors) help on a JRSC'd application? How about ignition?
exactly...Mugenpwr said:I'm running a Hondata programmable engine management system with 440cc injectors on my ITR. Fuel pressure is set to stock, (52 psi off vaccum) and I'm running 8.5 psi. The rising rate regulators suck and will always run extremely rich on the top end unless you use some sort of fuel control device, i.e., V-AFC etc., plus the stock injectors are being pushed extremely hard with anything over 60 psi. The proper way to do it is to upgrade your injectors so they stay at or below 80% cycle duty for your horsepower application and allow you to run your stock fuel pressure.
I doubt the used NSX injectors will save you anything over the aftermarket ones. I've seen RC 440cc selling for $285 on GB and I heard the lude's were like $125 each so that would mean like $500 for the set! $$$sweet said:i personally don't know of any bigger Honda injectors than the Lude H-series motor, though i'm sure that the NSX V6 ones would flow quite a bit. then again the NSX injectors may be almost the same as the Lude's since there are 6 cylinders stead of 4.
but i wonder if they would be plug and play if you can even get your hands on a used set??
it would be nice to get a hold of bigger Honda injectors than the Lude's. it could save some $$ and may work well.

Not sure of what size the NSX injectors are. We are just told that they are
a Honda injector, no specific one. You should be able to use the NSX from a
3.2L without any mods. Thanks.
