Hi guys im going to get a custom plenum made from CCP,Ariel has asked whether or not i want the standard 11mm or the 14mm injectors.I know the bigger the injector in CC's the more flow but does the bigger injector have any performance increases to,meaning 14mm over 11mm.

He is talking injector boss for the manifold I am assuming? not sure what injector would fit a 14mm boss? I know you can easily get direct upgrades for ca with stopck manifold. I would stick to stock?

what sorta $$ does it cost to get a custom manifold these days?

$1400

just keep it standard size, you can get adapters these days for the bigger 2000cc injectors. fuel rail height and id size for the injector hole is more important.

Ive heard that the standard injectors can lean out,im aiming for 300 hp,will they cope with that?I dont know why im concerned with it as the auto shop thats doing it would know all this anyway.

300hp on standard injectors.. No way.

I think standard injectors are only 325cc at standard rail pressure.

You can easy get 1000cc injectors that fit on a standard fuel rail if you want to run E85.
I don't know why you would want to move away from standard physical sized injectors, unless the bigger ones are either cheaper or available in higher capacity.

Hi Dattodude so is there anything i should know for getting the custom manifold made.

yeah i meant standard 11mm not cc rating
I have some new 534cc,700cc injector power enterprise/denso. Need them gone will let them go below half price

Hi oda me not being up to date with injectors,will 700cc be enought for 300 hp?not to worried about e85 fuel as i dont think u can get it in Goulburn anyway.Are denso good quality and what sort off price u after.
