Right Injector Sizes

[Markie]

Just wondering what size injectors would be right for me.

I dont use the car daily, more weekends, but I do want it to be able to drive normally ie idle correctly..

 

But I also want the injecotrs big enough to cope with future single turbo upgrades..

 

However I want HKS injectors to go with my HKS rail and they only do top feed injectors of size 680 or 1000cc..

 

Intending to run a GReddy e-manage first off, then possibly AEM stad-alone in the future..

 

680 stretching the limits / 1000 cc injectors too much and just for drag cars?

 

Any info will be welcomed,

 

Thanks..

With your current spec, on stock turbos, definitely 680cc max. These should also support a reasonably sized single turbo (eg. BL T67) I suspect the e-manage wouldn't cope with mcuh over this either. You'd only need the 1000cc if going for a BIG single.

Very very roughly...the 6x 680cc injectors on a 3L engine will support 680BHP...will you really be going for more power than that?

 

EDIT - and the bigger you go injector wise the harder they are to control...match the injector to your power requirements.
