Upgrade advise on stock 560cc Injectors...

Hi Guys,
im planning to upgrade my stock 560cc injectors to either 750cc or 800cc injectors.

1) But before i purchase the new larger injectors, how do i know is it plug and play direct replacement to my stock injectors?

2) Which is better (Low or High Impedence) and what is the different of the both???

3) What type (Top or Bottom fed) is our Evo injectors?

4) Lastly, will putting in a larger CC injectors can increase hp and reduce turbo lag?

Thanks and im looking at 350~380whp...

I can only help with no 4)

On their own injectors wont reduce lag or increase power unless your current injectors are maxxed out. If you have a big turbo and cant increase the boost because your injectors are too small, then they will increase hp (with a remap).

I'm not sure you need largers injectors to achieve your goals.

As said above, you'll need to upgrade them if the stock ones are maxed out when remapping.

EDIT : my mistake, I've read "hp" instead of "whp"

750cc should see 380WHP
The impedance is the resistance of the injector solenoid windings. Evos have low impedance or "Peak and Hold" as there known.

Hi Guys,
im planning to upgrade my stock 560cc injectors to either 750cc or 800cc injectors.

1) But before i purchase the new larger injectors, how do i know is it plug and play direct replacement to my stock injectors?

- I recommend Sard injectors. I Purchased Sard 800cc ones for my EVo6 when I installed Evo9 turbo. Check there website as it has part numbers for Evo's think its part number : 63518 (Low imp)

2) Which is better (Low or High Impedence) and what is the different of the both???
Evo's are generally Low

3) What type (Top or Bottom fed) is our Evo injectors?
-Top feed

4) Lastly, will putting in a larger CC injectors can increase hp and reduce turbo lag?
Nope.Will help if you maxing injector cycle.

I make 245kw atw on my TME with Evo 9 80 series turbo,Apexi power fc,sard 800cc, hks272, 3" apexi nur spec from turbo cat back exh, and 1.5bar boost and apexi sus filter if that helps

Thanks and im looking at 350~380whp

Top feed and low imped is the type you need.Stock would be maxed out at about 360bhp ish and yes could manage but at limit i went over kill and had 800cc running at 70% duty on just under 400bhp at wheels.
