Default Injectors

Would 345cc injectors suffice for 1.4 (D14A4) engine turboed to 8psi? In case stock fuel pressure is too low, would raising pressure (staticly) help that hey would be enough?
The reason why I ask is than Honda Prelude VTEC 92-96 year has those injectors, and I belive they would be easier to come by in Europe - so boefore buying anything just want to make shure.
I plan to use Apexi S-AFC II with those.

d14!?!? are u turboing a moped?

u can use the 345cc's and just keep the afc at less correction...


-30% instead of -40%

345-30% = 241.5cc (thats for idle) u want richer when in boost.

You can't always use that formula. Apply that same line of thinking to 450cc injectors, and you'll have to lean out your injectors to -46%, which anyone who runs 450cc injectors with an AFC "hack" will tell you, is too lean.

Plus, it's not an issue of settings, it's an issue of providing enough fuel, before saturation of the injector, during boost. Will a 345cc injector give enough fuel at 8psi? That will depend on cfm of the turbo..

Which turbo are you using?

Hehehe... not really a moped.. but...
Anyhow, it's originally 90HP, hoping I could reach 140, maybe 150HP with 8psi.

So far - none.. hopin to find KKK K03, or maybe an IHI (from Fiat Uno Turbo). Still searching for those.

I don' tknow the specs on the KKK, but the IHI should work OK with those injectors.
