As much as I'd like to go with the norm, flow force are priced out (almost above getting id1000's locally) due to import tax etc.
I've been taking a look around and found the following flow matched sets of EV14 bosch, at 550cc. (they can also provide loom for USCAR > Denso conversion)

Assuming the flow matching is decent, are these alternative to the flow force injectors? I can't justify spending on ID1050x or gambling with yellow top rx8's.

I realise they say they are "professionally modified" which makes me a bit nervous, but if they have been flow benched and matched, I assume this is ok.


Car: Stock JDM eunos (NA) 1.8L, currently has MS3X (Trubokitty method), upgrading injectors and tuning while waiting for kraken TD04 manifold+exhaust is delivered (~1 month hopefully)

 

Are the smaller capacity ID injectors any cheaper or roughly the same price?

Unfortunately most (not all, but most) of these EV14 injectors sold as flow-matched sets aren't that great. Might match under moderate to high load, but can be junk in low load areas.
Lots of these companies just give you bullshit dead-time data which is essentially ripped straight from ID data or or done under shitty conditions, giving shitty results.

If I were in your shoes I'd pay the premium for either the Flow Force or the ID1000's as they have been proven to work with reliable and accurate data.
Skimp out on other things but I'd spend money on injectors.

too much assuming going on in post 1.
Assuming the product is good, assuming it will work right, assuming.....we pay money for facts and data, not assumptions and guesses.
