Yes.

Remember, it's always easier to subtract fuel, than add fuel, as was mentioned earlier in this thread.

Obviously, don't install the new injectors until you get some sort of fuel control.

I found some 680cc I'm going to try to make him a deal with my 550cc. I would like to know how big of a turbo could I use if I wanted to go bigger. I can I get a hybrid

Are the 680's the correct impedance for the engine that you'll be using? You may find that you have to wire in new resistors.

http://www.fc3spro.com/TECH/MODS/FUEL/inj.htm

4 x 550 is just about equal to 2 x 460 and 2 x 680, with the latter outflowing the former just slightly. Up to you if you want to trade for the 680's or just buy another 550 set. If I were you, I'd first check the impedance of the injectors in my motor and make sure it's the correct type. Then I'd get the 680's.

not that big, you're really running about stock fuel. Look to Ted's page for recommendations. I gave you the link above.
