You will have 380cc injectors with a grey top (under the plastic plug that is, which may be grey or black).
Depends on the power output your trying to acheive. I won't go into theoritical maximums, but will say that 280-290hp is historically a reasonable limit for the 380s. And that around 350-360 is ideal for 550s, although some have pushed 550s to over 400hp with a little extra fuel pressure.

"They essentially fit, but need some rearrangement of piping and optionally and extra tie strip on one end of one rail. "
Does anyone have pictures of one of these rails fitted to an early phase 1 car...? I think that this is going to be the best (and cost effective) approach...

Hi Paul,
i have just got my hands on some 440cc injectors, walbro fuel pump and a 1:1 fuel reg for my MY95 WRX
you say 290bhp is the max for the 380cc's, do you have any idea what it will be for the 440cc injectors with a raised fuel pressure???
thanks for all your help

Mike,
Sent you a mail. Essentially I have plenty of the smaller adaptor, and need to get some more of hte big ones (as seen in the above pic) made, I've used all of the last lot.
I will keep a few about as I am sure you won't be the only person wanting them

I think someone needs to state on a list/table, injector that are available for phase 1 and phase 2. The cc and the make
This post seems to be firing a lot of good things but it needs someone to sum it up.. Paul...?

halelluah (or however you spel it)
yes they are nippon denso parts. Even when you buy them from Blitz etc, same thing. BUT, you can't normally buy them except through a Mazda dealer, and they are £180 each new inthe Uk from a dealer, some mazda breakers want £100 for used ones.
Thanks for the leads though.

Paul,
If I was to buy injectors from http://www.phase2motortrend.com/fuelsystem.html
Can you supply the adaptors to fit a phase 1 rail?
If so, can you let me know how much £££'s..?

Pavlo, I am having some "issues" to fit 850's on a Phase 1 rail. Mine are idental to:
Well this are the ones i've got and i have Phase 1 rails. The injectors seem to be sourced from AVO. And I have tried fitting them into the fuel rails and they do fit, although they are way shorter than your regular 440cc yellow injector. The problem is that the little hat that goes on top of the injector (are these the retainers ?) doesn't seem to be as close or sealed as in the case of the original yellow injectors.
So should I use an aditional adapter like the one you were offering for the Blitz 550cc for Phase 1 .... or does it just have to look similar to another picture you posted (my injector when installed looks a lot like the injector on the right of the following pic):
and also the plug that comes doesn't connect to the injector and it DOES connect to a OEM injector
thanx,
Carlos H.

Next is an 850 injector, again from the same family, but slightly shorter in overal length, body diameter the same though. This is sold by Blitz, AVO and numerous others.

Okay, I see your problem.
The phase 1 fitment is not so easy with the 850s, but I will be sorting some out in the near future (next week I should hope).
As for the connector, the OEM connector will fit on the injector if you remove the 2 small rails each side of the connecter on the injector. If you look at the 850 and OEM 440 in the pictures you will see they are in different positions. I have removed them on all the injectors I've supplied and there hasn't been a problem.
As for the retainer. I have removed some of the plastic material at the top of the injector to effective reduce the diameter of the plastic flange, this allows the retainer to fit on if you remove the small rubber pad that normally sits inside the retainer. When fitted to the Mazda, there is no rubber bung. To really finish it off, you really want some small plastic spacers about 3mm thick, but I would need to draw a picture (or take a photo). I will have some 850s in on monday, so I will take some pictures so you can see just what i mean.

Thanx for the reply
Well after looking at the injectors carefully I think that I may not have as much problems as I was expecting.
This is the regular 850cc injector that needs to be adapted:
and this is my injector:
it is slightly different.

Yes, that retainer should fit, it's very similar to a MY00 style retainer, but you will probably be left with a small gap under the bolt area as the MY00 rail is recessed.

What I don't like, although it may be ok, is that there is a gap between the retainer and the 850 injector, while on the OEM injector there no gap.
(on the left side is the 850cc injector tried on a "damaged"
phase 1 rail, on the right side a 380cc oem injector)
(hope the gap between the top of the injector and the retainer can be noticed .....)
thanx for the reply Paul.

I think the retainer is still clamping down on the large round surface of the injector, although if the injector floats up an down a little, this isn't a problem.
They look fine to me. What I do to check is pressurise the rail with compressed air and check for leaks.

I got the 740cc (Tomei for SR20DET) from Phase2 the other day. They look virtually identical to the original yellow 440s on the MY99/00, plug may need to go in the other way round, will confirm. I ordered with O rings, not assembled it all yet, will probably wait for new engine.
They have a bit of a backlog as apparently loads of Subaru types have been approaching them

The purple topped 550 injectors are actually OE for a series 5/6 Mazda RX7 twin turbo.
I have purchased approx 60 of these over the past 6 months from various sources, they are now very hard to find for sensible money in the UK.
The Tomei 550 injectors are a drop in replacement for the phase 2 rail. I suspect they can be fitted into phase 1 rails with some extra parts, but I have yet to sort that 100%.
The RX7 style injectors I have fitted to both phase 1 and phase 2 rails, so right now I would say they are the most certain in terms of getting them to fit. But I'm doing the conversion parts for about £60, so you need to add that to the overall price when comparing. Parts to fit phase 2 injectors into phase 1 rails would be just £30 (half the number of parts).
If you have a early phase 1 car, so 91-1st half 96 ver 1&2, you can fit 99-00 phase 2 fuel rails on the manifold with a little work. They essentially fit, but need some rearrangement of piping and optionally and extra tie strip on one end of one rail. You can pick the rails up for £45 from a breakers, so this may be preferrable to people looking for 550s for early cars, i can't be arsed myself.
I am all done with supplying actual injectors, please don't ask me to. Sorting o-ring seals and conversion parts I am doing as that enables people to buy injectors from a far wider source.
Huh? Nothin to do with me, honest guv
Cheers
Paul

Thanks,that,s a quik one Andrew!
Do you also have any idea how much dutycyle they will run then,knowing they run 97% now at aprox.6000+rev's.
And finally,could the 97% the 380cc injectors run now,cause problems in 5th gear running towards topspeed?Mind you,the car ran 255km/hour befóre remap(est.218BHP),and áfter (est.280BHP)it strands at 240km/hour.:confussed:
I mean 280BHP is about the limit of 380cc-ones I understand.
