5th gen injector options including VQ35s
Don't bother asking for Maxima injectors, since they're listed as 350Z injectors.
Prices I've found searching the net and available sizes:
RC Engineering(~$650) - 370cc, 440cc, 550cc
Power Enterprise(~$800-$950) - 380cc, 510cc
Details:
RC Engineerings' - require splicing on injector pigtails and are somewhat different sized/shaped then OEM, so be prepared for somewhat a struggle forcing them into the rail and manifold.
Power Enterprises' - are a "drop-in" OEM replacement, ie NO splicing or tough fit. Plus, the 380s have 10-12 holes and the 510s have 8 holes for superior atomization supposedly.
Now, you VQ35s have advantages/disadvantages over the VQ30 5th gens.. First, your guys fuel pressure is a constant 51psi at idle and WOT. This means if you chose a 380cc injector, it's really operating at ~410cc. This is good at WOT, however at idle this can be an issue. If you chose, 400+cc injectors, you'd better have eManage or similar. Second, your returnless fuel system will require an external aux fuel pump and a Aeromotive DECU(~$400) to ramp up additional fuel pressure. No option to run a cheap FMU like the VQ30s can run. However, you could also easily have Techno Square make a custom program for your injectors. They at least offer one for FI 350Z guys running PE 380s that I've read about.
Tired of waiting...hoping to help convince some FI guys to buy now and quit being so cautious.

Just curious, who would be interested in PE injectors?
I have a friend heading to Japan in a couple weeks for about a 5wk. stay. He's going to see what kind of price he can get over there, IF he can even find them. However, I suspect with the sh!tty dollar/yen exchange rate, it won't be too much cheaper. Probably just save a little plus shipping costs.
If the price is better then what I've found from the US importers ~$900, I'll pick up a set or two of each size. It will probably be a one-shot deal, but he does go back every couple months. As long as he doesn't mind being a pack mule and it's reasonably cheaper, I'll front the money for a few sets.
This is just a feeler...it may never happen. Just sick of seeing $160-$180/injector.
