That was my concern.i've run these injectors over the years on emu...stock 295cc, mazda 360cc, mazda 460cc and subaru sti 565cc
the stock 295cc and subaru 565cc have been perfect on idle, cruise, and full throttle (boost)..these had several holes at the bottom of each injectors to create fine spray patterns
the mazda 360cc and mazda 460cc have been good on full throttle ,,however they occasionally caused a "jerking/judder" on idle and cruise for some reason...these had "one" hole at the bottom of each injector,,so the spray pattern was not the best
all were cleaned and flow tested before installation
yeah..you will need bigger injectors than 370cc for your goalsThat was my concern.
I have some Toyota 370cc injectors that match the spray pattern of the stock injectors, but they may be a bit too small for 1.4 bar boost.
Do the Subaru ones require different plugs and/or a resistor pack?
Thanks for the info. I will stay away from the Chinese stuffyeah..you will need bigger injectors than 370cc for your goals
the Subaru 565cc injectors were a direct fit to the 4e/5e fuel rail and same impedance (no resistor packs required) ----all you need to do is remove two of the black plastic spacers (one from each side) that are used to secure the injectors to the fuel rail...they come in pink and medium blue...if you go this route, try to get some genuine ones from the subaru forums, those guys are always upgrading and sell them cheap...i'll have to search for the year/model Subaru sti they came from...
be very careful with ebay...they sell a lot of cheap fake Chinese knock offs.
Any other options out there from anyone else?
Been looking at the Bosch injectors. Seem to be pretty good value for brand new injectors that are allegedly direct fit (just need to replace the plugs or buy an adapter).

Thanks
Got some "hopefully" genuine pink Subaru 550cc injectors on the way.i guess you have to do some research on them...the price seems good...you have to make sure spray pattern and atomisation are good too,,as that will be important to the quality of your tune
Hi, I'm having a little bit of trouble getting the car to run right with these injectors. It's ok now I have played around with the lag time to get the fuelling about right. Im struggling now with the revs dropping when coming down to idle, it will often stall.i've run these injectors over the years on emu...stock 295cc, mazda 360cc, mazda 460cc and subaru sti 565cc
