I'm looking for a semi-modern low impedance fuel injector, with a Bosch style plug, that flows around 25lbs/hr at 43.5 psi. Preferably at least a four pintle design, and preferably something common enough to be able find at a junkyard. Any ideas?

In case you're wondering, I'm looking for a plug and play injector for my '84 944. It has the old single pintle style injectors, and they leak ever so slightly.

Are mustangs low or high impedance? Also I want to say some 5cyl volvos are low impedance maybe the early na ones. Double check what I say its been a while

GTR injectors? As in R32-R34 Skyline ones. They are a cheap "budget build" buy like DSM injectors.

GTR injectors I believe flow 40lb/hr and are low impedance.

I don't know the major details about them. I haven't bought them because I can't use low impedance however they are very popular to use.

Should be common enough on Ebay and Nissan forums.

Only thing I came up with that was close is the ford 2.3L Turbo lima motor out of the Turbo Coupe T-Bird and the SVO mustang but those are 36LB. The modern ford stuff is all high Imp.

Static Flow Rate: 380cc/min at 43.5 PSI/3 Bar, 410 cc/min at 50 PSI/3.5 BAR Coil Resistance: 2.5 Ohms Voltage: 8-15 Volts, Nominal 13.5 Volts Amperage: 1.0 Amps Latency (dead time): 0.255 ms at 14 volts - Complete latency table sent with each set of injectors. Minimum pulse width: 1.4 ms Excellent atomization for medium compression, single- and multi-valve engines. Injector Dimensions: Overall length: 3 in./77 mm O-ring to o-ring: 2.6 in./66 mm Diameter: .95 in./24 mm

Will not require more than 1% trim Pressure: Min. 36 PSI (2.5 bar), Max. 101 PSI (7 bar)

Also 4cyl turbo volvos use 300cc (29lb?) Low impedance @3bar. while not the exact size you want its closer than everyone elses suggestions but is pintel style like the 2.3 ford turbo injectors and not the newer disk style like you prefer

If you don't mind sifting through spreadsheets you can get data on many different injectors on these sites.

Judging by those sites, nearly all 4-hole Bosch EV6 injectors are high impedance. The only low impedance ones I found are these 69lb/min monsters that you aren't going to find in the scrap yard. Part number B-280-431-130.

For the earlier EV1 pintle design, these Volvo turbo 2.3L 28-30lb/min injectors might work for you. Part number 0-280-150-357

Before you install, TEST THEM! I bent a conrod in my Alfa 164 after installing some Volvo S60 injectors that I did not thoroughly test beforehand. That was a very expensive lesson learned...

Toyota 22rte? 290cc low-z EV1 plug but only single pintle.

Thanks! I checked through the first site pretty thoroughly before posting and the closest I could find was a '95-ish dodge 318, but they were around 23#. I'll scour the rest of the links when I get time.
