Hi guys,
Been working on this 98 RS single turbo conversion and have some trouble getting to the bottom of an injector question. The car came with injectors that appear to be these:

Which if the picture doesn't insert properly is taken from here:

I have since found some of these:

I cannot for the life of me figure out if I can simply swap these out. One of the ones that came in the car is broken so want to replace them all, they seem to fit in the rail and both seem to be 440cc so is that fine? I've been reading up about phases and converting the rail and everything but can't make sense of it sorry.

Any help is appreciated.

Cheers

there is a physical size difference between phase 1 injs and phase 2 injs. They don't fit in each others rails

If both sets of your injectors fit in your current rails and they are both rated at 440ccs then you should be fine to simply swap them out.

I'd replace the O rings and smear them with a little rubber grease before you push them back in

So there are 2 phases of side feed injector. The first picture is the phase 1 style that were pre 98, and the second picture is the phase 2 type 98-00. You need the rail phase to match injector phase. You could probably grab a set of rails from the right phase of a nonturbo/wrx/legacy ect as the rails should be the same (with different cc of injector fitted between models). The only thing you'll wanna be aware of is bolt pattern to the manifolds varies between models.

Ecu wise I'm unsure if they are the exact same CC,or if the ecu sends the same signals between models to fire injector, if they are they are the same they can probably be swapped over with the correct rails to match.

Thanks for that. Will have a go at putting them in then and make sure everything sits snug and connects up. Will put up progress once done.

Cheers!

Both yellows flow the same thankfully. To avoid future mismatches, do not refer to your car as a 98, use chassis codes bro BD or BE, or lie and say it's a 97 or 99 for example.

<Shale>: Blighter doesn't really have an accelerator pedal, it's more just a loudness pedal. You can change volume, but you won't go any faster.

<Reuben>: I feel like when you stomp the throttle in Blighter, it's like you've startled an old man!

Just ended up buying some Phase 1 off TradeMe as the Phase 2 weren't actually fitting (as suggested above). So now just trying to get rid of the Phase 2 ones.

Phase-II are the decap-able ones, and fit in non turbo fuel rails also. Bare that in mind.
