I got a couple of different answers from different tuners. I did a search and didnt find much. Anyone? Thanks in advance....

I have gsc s1 cams, head studs, IC, exhaust, MBC...

 

you will be running your stockers hard to hard, any smart tuner will tell you get injectors. you dont want to take chance on a turbocharged car under boost, always have enough fuel and you will save your motor

i would get some 880's even 1000cc, why because you will want to do better things down the road it never fails,you will have need for more power once you get usto the FPgreen

 

Yes, you need injectors. You don't want to max out your stock ones. If you plan on just running pump gas, 750cc's are good enough. If you plan on running E85, you can just go with 1000cc's minimum. Idles fine on pump gas and plenty of fuel for E85.

 

i got some 1000cc with the green on e85 .. it was recomended by my tunner if that helps

 

Simply put, for safety, yes you do need injectors.. Depending on the mods.. 750's/780's minimum to 880's (pump gas) or 1000's for e85..

Just some added question to yield added advice...

On the 1000 CC injectors, are there any that are flow tested, and matched out of the box?...or balanced...? I am not sure of the term here, but getting them flow tested so they are all within the same specs and flow the same...balanced I would have to say. I know this is personal oppinion, but that is why I asked if any manufacturer flow tests and balances them, so they are ready to go out of the box.

Thanks in advance

 

RC engineering send a flowsheet and are matched within 1 or 2 % of eachother.

 

Thank you, exactly the info I was looking for. Any others that do the same, and has any one tested the spec sheet that comes with the RC's. Flow tested them after recieving them to see if they get the same results as the manufacturer?

 

I never tested them , but I'm the trusting type of person. I still have faith in people. I'm sure my tuner would have noticed a cylynder running rich or lean, like I said I have faith in people.

Thank you, that helps with the tuner seeing the same specs from a tune perspective.

Well for the original poster of the thread, should give you some good specs to go off of, and ideas for manufacturer's.

I have come across injectors that are off by a more than a few percent. I asked these question to get a feel for added info for the person buying injectors needed for the upgrade, and just some added advice for said injectors and choosing them based on actual numbers.
Even if one cylinder leans out, the motor still goes boom!
