would 660cc injectors make a bigger difference than 550cc? also does anyone have the greddy kit installed and are there any numbers? I know www.hopupracing.com is already selling it.

 

U will probly get some idleing problems with 660's

 

Your best bet would to talk to PR_Racing. They sell the kit as well as a tuning/injecter package, like Hopupracing does. They should be able to lead you in the right direction.

so do you think 550cc is fine?

 

What are your goals? How much HP?

 

maybe 350 to 400

 

I dont that you'll be able to run that safely on stock block for a while. You have plans to build your engine?

550cc injectors will the greddy kit will be fine for that turbos potential.

 

Search is your buddy.

Turbonetics are using 60 lb injectors (630cc)
and the Greddy kit is tuned w/ emanage for 440cc injectors.

The stock fuel pump @ 8psi of boost provides enough fuel pressure in the turbonetics kit, so 440cc injectors there will be no problem.

On the other hand, @ 12 psi you should get a new fuel pump for the turbonetics kit to provide enough fuel for the 630cc injectors.
I am not positive, but running a 5-8 psi with 660cc injectors should be okay..... but I doubt you would need such large injectors to begin with.

I personally think 440 is fine for the tC and I was suprised when I heard how large the turbonetics injectors were.
