It's alive finally!!!!
Well after a long stress month my 7 is back alive. I had problem after problem with this setup but it is finally up and driveable. It pulls very strong at 10lbs but is going way rich. Do to I am running a Supra fuel pump with 720cc secondary injectors with no way to adjust fuel pressure down so I have to get a FPR and turn the fuewl pressure down and hit the dyno. It should put out some nice numbers. For you of those that don't know what setup I am running. I have went with a T4 manifold with a T4 t04b garret turbo. well I will update you guys or let you know when I plan on hitting the dyno and let you know what it put out but I am hoping around 350-400 rwhp.

Gonzz it is no thanks to you that my car is up and running. I had to spend another 600 dollars on a brand new turbo and wastegate. Cuz you wouldn't answer your pms on the blown turbo and bad wastgate that you sold me thats all it is good for is a paper weight.

Sounds more like Rtek territory to me. ?. Standalone more so with that turbo. Unless I am barking up the wrong tree.

I have talked with several people befor purchasing these injectors and they said I should be fine with fuel. I have even talked with a professional AEM tuner that tunes rx7's and he said as long as I tune it right he sees no reason why I shouldn't hit those numbers. But I guess it will tell when I hit the dyno. I am not to sure myself this is my first high power rx7 I have built and I am going step by step. I will keep you guys updated when I hit the dyno and let you know what I put down.

spending too much money..

ok but just as a word of advice. Most people running the stage 2 and stage 3 bnr hybrid turbos pushing around 300-350 are using 720x4 and 550x890cc injectors and most of them have haltechs etc... Unless I and everyone else is totally wrong then I don't think you will have enough fuel but here is a fuel calculator to show you what injectors support how much hp.
http://rx7.com/cgi-local/2ndgencalc.cgi
there you can see that the stock 550cc injectors at 80% duty cycle only supports 253fwhp and if you put 720cc injectors in it only goes up to 292.8fwhp at 80% duty cycle. Now people putting 720x4 or 550x720cc injectors in, they will support 332fwhp at 80% duty cycle. Now I'm not sure about you but most people that are getting stand alones will usually opt for the biggest injectors they can find for secondaries and will go with like 890cc primaries because the standalone can tune any injector combo you can through at it and with that much fuel it will support just about anything.
edit: I know the calculator isn't the holy grail of calculators but it gives a pretty damn good idea of what those injectors will support.

All tuning will be done with a wide band and a dyno. The tuning that we do is very procise. If I only hit around 350 I will be happy till I get a stand alone and bigger injectors I just don't have the funds for that right now.
