the 19 will be perfect for any 4.0 up to 200 HP

for a reg 4.0 yes... but not the HO right? cause everyone else is saying the 4.0 HO runs a high injector...

What you have:
4.0L
'96-'98 #53030778 23.2lb/hr @ 49psi
'99-'04 #4854181 22.5lb/hr @ 49psi

2.4L
'96-'02 #53030778 23.2lb/hr @ 49psi

'96-'98, ........53030778, ...Grey, .........49psi, .................23.2lb/hr
'99-'04, .........4854181, ...Blue tip, .....49psi, .................22.5lb/hr

Replacement:
Ford Motorsport 19.0lb/hr @ 39psi (Part no. FMS-M9593-C302)
Ford Motorsport 24.0lb/hr @ 39psi (Part no. FMS-M9593-A302)
Ford Motorsport 30.0lb/hr @ 39psi (Part no. FMS-M9593-B302)

Pre 96 the fuel pressure is lower at 39 PSI.

'91-'93 #33007127 21.0lb/hr @ 39psi
'91-'93, ........33007127, ...Brown, .......39psi, .................21.0lb/hr

The Ford injectors are rated at the same pressure, so yes, you can do this as well..... By using:
Ford Motorsport 24.0lb/hr @ 39psi (Part no. FMS-M9593-A302)

'86-'90, ........53003956, ...Black, ........39psi, .................18.6lb/hr

These would be your direct swap ins...
Ford Motorsport 19.0lb/hr @ 39psi (Part no. FMS-M9593-C302)

I believe they can be found in any newer Mustang with the 4.6L

little math for ya.
Injector size (lb/hr) = (horsepower x 0.5)/(no.of cylinders x 0.8 )
So say you have a 250 horse I6...
100/4.8=21lb/hr injector

So for a 30 lb/hr injector, you would need about a 290 horse motor to utilize them.

i have 65lb injectors in my cobalt.... and they are tuned to the max.. lol

So those of us with the Renix want the FMS-M9593-C302 injectors?

huntingman2706217

i think thats right... and then with the HO you would need the 24's... Part no. FMS-M9593-A302... wait... what color are these? blue right? the 19's are pinkish?

There are better alternative for the right injectors, Renix should use the same flow injectors as the HO, the stock injectors for Renix flow 240cc, HO flow 248cc (up to 95) and 234cc (96- up). BUT, the Renix and OBDI flow at 39PSI and the later 4.0L flow at 49.

Injectors flow is always measured at 3 Bar, 43.5PSI. This is a reference point and from this you can calculate the flow to your system working pressure.

So, why not Ford Bosch 0280155710? because of the above, flow about 210cc, and doesn't have a clip nut for holding the injectors leveled.

Why not FMS A302 255cc? too much flow for any stock 4.0L and old design, not as efficient as the newer EV6 Bosch injectors.

The better alternatives are in house injectors, Neon 2.4L 95-96 have 238cc injectors in it, 0280155703, these are EV6 4 holes injectors with clip nut. Better fuel economy, better throttle response, better power.
The disadvantage is that you'll need to take these out of two cars..

Another alternative are the LS1 injectors 0280155890, flow a bit less than the Neon injectors at 3 bar but will do just fine in any 4.0L. Some refers to these as 26.6lb/hr injectors but this is the flow at 4bar, at 39PSI/2.7bar will flow 21lb/hr

So why replacing 248cc/min injectors 238cc/min? the EV6 injectors are capable of better atomization of the fuel hence less fuel is needed each stroke for the right A/F mixture.

If there is a need for more flow one can use the 96-97 Taurus/Sable V6 injectors, 0280155715, these are EV6 without clip nut and flow exactly the same at the FMS A302. Or LS1 0280155931 which flow a bit less but does have clip nut. Both will out perform the older EV1.3 A302 injectors.

Last, don't use lb/hr for rating injectors flow, as it always calculated from cc/min since injectors flow is Always measured using cc measuring tube. Some use 10.5 for calculating lb/hr, some use 10.4 and neither is correct.

mike37

for a 89 stock motor the ford 19# work better that stock
you can use the 24# if you want
newer jeep not sure the exact year but around 95-96 you need the 24#
because of changes to the system

mike37

you know your sh!!!!!!t good post
thanks this needs to go in the tech write up section

You guys have me confused as hell, with all of these numbers, pressures, colors.

Just tell me a simple color, part number and make of injector that would be an "UPGRADE" from the stock injectors in my 91 4.0 HO motor. Just my application, no others. Please.

coas

Stock Neon 2.4L injectors, 0280155703.






Forgot to mention that these are all with jetronic connector, as in the above picture. For later model the injectors are already EV6 but if there is a need for more flow then the 1999 only Taurus/Sable injectors, 0280155849 will flow 265cc/min @ 43.5 PSI, same as the A302 but with USCAR connector.

offroadnut36

umm yeah im so confused with lb/hr and psi's and colors and makes and clip nuts(BTW what are clip nuts??)

for a 90' renix 4.0 what color and part number should I get? and what cars did they come in?

coas

This is an injector without clip nut, compare to the above picture:
