Injector Capacity?
I'm upgrading my nitrous shot. I've got my new FP and FPR. From what I've read, the next week point is my injectors.
259CC stock, right? How do we know when they are beyond recommended operating range?

huh
I'd love to know the answer to this also. If the vg30 and the 6g72 in my VR4 are comperably efficient, I wouldn't run those stock injectors past 315 hp at the crank. I'd keep it under 300 to be safe.
Real experience is clearly better than theory, but if nobody else replies, I guess you can measure or estimate your crank hp & just go from there. I certainly wouldn't have put an 100 shot on a max with stock injectors.
If you replace them though you'll need some sort of electronic fuel controler. An alternative would be to take them out and send them to RC for port & balancing. It'll cost $124 for all six injectors, and they were able to get an extra 20 cc/min out of stock VR4 injectors (not to mention balance them all to within 0.1 cc/min of each other). They're still stock though - so no ecu problems.
