Quick answer on injectors needed
Need a definitive answer to this quickly, as I've just been offered some injectors.
My car is a v2 STi 555, and I've just bought a turbo upgrade and to my horror have discovered I only have 380cc injectors and not the yellow 440cc that I thought I had. Anyhow, I've just been offered a freshly removed set of yellow 440's and plan to fit a Fuel Pressure regulator with them for my VF22.
My question is this, as my car is a Phase 1, will these yellow injectors be a direct fit or will I need a Carl Davey adapter set to use them?
Alternatively, these injectors are coming complete with a fuel rail from a facelift car (Phase 1.5 or 2), will this fuel rail and injectors be a direct swap for the phase 1 setup on the phase 1 Inlet Manifold?
Sorry for all the questions, but need to quickly get my head round this so I can source exactly what I need.
Many thanks .

If the 440cc are long nosed Ph. 1.5, then they are direct swapover (same pattern as Ph.1) - no fitting kit.
Ph.1/1.5 style:-
If they are short nosed phase 2, the the CD kit is needed.
Ph.2 style:-
Not sure on rails compatibilty - I think both 1.5 and 2 rails are a direct swap for Ph.1 rails, but don't quote me. If they are, then happy days, as obviously the injectors won't need to come out of their native rails for fitting.

Pics added to my post above.
But they're here, on CD's info on the injectors, etc:-

But I agree with 53 - you'll be maxing out the 440s (c.325-340bhp) before maxing the VF22, and long before a Bug TM's airflow.

Yep, think I need to try find some phase 1/1.5 550cc injectors, or will they be rare as hen's teeth. I'm guessing that I'll more than likely be limited to getting some phase 2 500's and a CD Conversion?
Cheers for your input guys, saving me squandering cash on the wrong items.

Well, it depends on the ECU choice. For example, Simtek (Alcatek) and Syvecs allegedly have great control - so why not 910? Future proofed to the hilt then.
Not sure how well ESL (or maybe Apexi PFC) - no doubt, the ECU choice the OP will opt for? - will work large injectors though. So yes, in that case, 550s would prob be wiser.
Not sure if LP offer differing flow rate options - proabably!

Thanks for the advice guys. I've bought some very cheap Phase2 440's that I'll get flowed to around 700, so plenty of headroom and future expansion too. And a set of CD's adapters too.
Oh, and I've also found out that the fuel rails only fit on the corresponding phase's inlet manifold.
