Another large injector option (1100cc)
So long story short I had been maxing out the 550cc RX-7 injectors on my 1999 even with the Walbro 255HP pump. This is with a GT2871 running up to 18 psi. I decided it was time to get larger injectors and started reading up.
The hot ticket right now for large injectors seems to be the relatively new Bosch EV14 injectors. The biggest ones Bosch makes are about 600cc IIRC, but lots of companies are starting with the base injector and modifying them for increased flow. They also add tophat pieces to adapt them to the fuel rail ports for whatever vehicle. This, from what I can tell, is how companies like Injector Dynamics produce their big injectors.
So I started surfing around and found good reports about injectors from Fuel Injector Clinic http://www.fuelinjectorclinic.com/. They offer an 1100cc option which is just about what I was looking for in case I try E85 later on. So I bought a set of the EVO 1100cc (modified Bosch EV14) for about $475 shipped with plug adapters. Like any of the modified Bosch EV14 injectors they are not cheap.
But so far I am really happy with them. The car is running great. And, though I am still tuning the idle, believe it or not, they are idling fine at 14:1 AFR. I daresay they idle possibly a bit better than the 550cc RX7 injectors were (which were cleaned and flow tested). This is important to me since the car is a DD so I want good idling and cruising behavior. So far so good.
It is hard to believe an injector this big can have good idle and cruise behavior but there it is. More later after I get to the dyno.

I am using these
http://cgi.ebay.com/ebaymotors/4-DEN...Q5fCarQ5fParts
The fuel they provide is enough for 450hp. I idle at 14-14.2 perfectly no misfires.
Also the ride quality is even better than the stock ones.
EDIT: I didn't read the whole thread. Good pick.

I looked for an ebay option before getting these but did not do it for two reasons. One, I could not find a Bosch EV14 1100cc with the proper length and feed port diameter. Two, I wanted to be sure I was getting them from a trustworthy source and FIC has a good reputation from what I have read/been told. The injectors came with flow test data (matched) and the dead time versus voltage data.

No direct link on their web site. You have to call them up and talk to them. FWIW the part number on my invoice for the injectors is IS126-1100H and the part number for the electrical adapter plugs is PADPJtoD4.
