Precision Low Z 780cc Injectors. Less than 10,000 miles on them. Asking $220 shipped. Also have a resistor box with pigtail I can throw in for an extra $20. If you need injctor pigtails I have brand new ones for $20.

yea i know, just seems a lot of fuel having 550cc injectors at 68psi rail pressure (seems like what you would need if you were pushing like 20 psi of boost)

No specific boost level in mind, looking for around 450WHP uncorrected on pump gas and boost only (another 150 on top of that with the direct port NX kit.) Engine management is done, motor is done, suspension and brakes are done as of this weekend, just need the transmission to stay in one piece (that won't happen) and still need to have the manifold built and the plumbing put together.
For that kind of power, I'll be close to the top of the map for a 0.78 A/R GT3071R twin scroll, so I might move to the 0.86 A/R GT3076 twin scroll instead, which would actually put me over into the ~500WHP arena. Either way, the 550's aren't going to cut it.
Besides, 550's at 68psi is only ~680cc/min. That's just barely enough to hit the 400WHP mark. The 780's should get me to the 450 mark (or at least, almost) and 68psi would put me into the 500WHP-safe arena. Just don't want a rising rate setup, as otherwise I can't jet the nitrous correctly.
