Will be getting Revhard II or Drag III for my 01 GSR in next 2 months. Are bigger injectors necessary to run at stock boost? I plan on getting getting a fuel pump but using stock injectors for now until I start bumpin' up the boost. What do you guys think?

 

Well I have the Rev-hard kit with stock injectors. Im making alot of power but I dont think that my injectors are supporting the horsepower im making at 8psi. So I think it would be a good idea to upgrade the injectors to like 310cc and a 10:1 FMU. Then if you ever go stand alone you can uprade the injectors again to something really big like 440 or 550.

I went ahead and turned down the boost some so I could feel safe with running my stock injectors.

i agree with arturbo.... he said it best

 

Wouldn't it make sense to just buy the 550's now because they are almost the same price? What fuel pump do you guys use?

 

your ecu cant handle 550s without some sort of piggy back system or a stand alone...
i have heard of some people using 440s with a apex afc..... but without a fuel computer of some sort, you should stick to 310s because with anything bigger your car wont idle right or maybe not at all...
btw i run the msd inline pump

 

Newsense, what else do you have in your setup, I"m looking to break into the 12secs eventually but don't know what else I"ll need such as ignition etc. What I"im planning on so far is RevhardII or Drag III, exhaust, fuel pump, Clutchmaster Stage III clutch and maybe flywheel, and prob 330 injectors. What else do you think I should buy to run at like 8lbs now and bump up to 12-15 later on.
Thanks again!!

 

I have a bosch fuel pump because IMO that is probably the only fuel pump that can handle the high fuel pressure that the FMU creates. If you go 330 you still wont be able to use it with the stock ecu. The biggest you can go is 310cc on stock ecu with out some sort of piggy back(Apex SVFAC) or Stand alone. I wouldnt buy a piggy back because after you spend all the money to get it with injectors you would have almost payed for a standalone.

I've heard of ppl using eclipse/talon injectors for applications that needed 450cc injectors. My question is, is there any 270-310cc injectors in any of the cars out there that will fit in a honda and be compatable with the ecu? I guess I am trying to ask is there any other way to get 270-310cc injectors without buying them from a place like RC?

 

Sorry, I'm a tard, I meant 310's not 330's. What boost will I be able to run then w/ my turbo if I"m using 310's? I guess I"m just wondering if I should just buy bigger ones now and some type of standalone system now?
