Injector CC to large?

[megamarine]

Alright guys and gals, since I'm aiming to add more power to my NA-T SC300, and allow better distribution, I started looking up some new injectors and stumbled across some Supra 750cc Injectors 2JZGE NA-T High Impedance setup. Now, is that to much to utilize, or should I drop to 500cc instead(I can't even find any that size!)? Any help would be great here, because I don;t want to drop money for something I cant use.

-Thanks

You can't find any 500cc probably because the size is 550cc..550cc injectors are what come in the US Spec 2JZGTE Supra set up...

750cc will be fine, they're good for up to about 700rwhp. Also, what engine management are you running, if a piggyback then the 750cc will be too much for the piggyback to control. I think the most a piggyback set up can control is about 680cc or so.

Ah, I see. At the moment it's running a AEM Digital Wideband Controller and stock ECU. Surprising isn't it?

nothing for fuel managment?, i would just go with 550cc injectors from a 89-91 turbo rx7, purple top injectors. they are direct drop in and are good for pump gas.

Map ECU sounds good. been meaning to do it too. The turbo is a T70 by the way.

I'm running 750s. The Emanage Ult. can control them just fine, but I wouldn't want to push too far beyond that with it though....
