Injector questions

[Morrison]

tinkerputzer, the part numbers I found for the 1999 Mercury Cougar injector are the following:

MOTORCRAFT# CM4885
FORD# XS2Z-9F593-AA
ENG# XS2E-9G593-A5C
BOSCH# 0-280-156-041

They should mount right in to the manifold and rail the same way, but I just noticed that the electrical connector is different. These have what I believe is referred to as the EV6 style connector.

I don't think it would be hard to snag a set of connectors and solder them onto your harness though.

Or you could use these adapters: http://www.americanmuscle.com/mustan...apter-kit.html

are the 17lb injectors plug and play? or do i need an entire conversion kit and stuff?

[Evan12]

better control? the 14.5# are widely known to be barely big enough to run the stock M20.

i have heard this aswell. that was why i was asking.

[tinkerputzer]

You can also get 17 lb Bosch design III (plastic bodied) injectors from a 1999 Mercury Cougar V6 I've recently found out.

Do you know the bosch part number on these?

[tinkerputzer]

Do you have dyno data before and after?

Or at least 0-60 or 1/4 mile times?

No and no. I think if you tried them though you wouldn't complain. They match the engine quite well. I have been running them for almost a year with no issues.

yes, 19# low impedance

i knew they were low impedance, but i didnt know they are 19lb. cool.

do you know a reason why? .2L surely cant be the reason.

[Evan12]

well i thinking of going to 17# because im going to do a maf conversion. and i also heard running track on 14.5# injectors isnt that great because your running them at their max almost the entire time.

^ jlevie dropping the knowledge again.

etas are 19#

really? :o

Unless you've done something to significantly increase the mass flow through the engine, larger injectors aren't needed for an M20B25. If the fuel system is working correctly and the injectors are clean and flow at their design rate the engine can be tuned for a A/F ratio of 12.8:1, which is as rich as you'd want to go.

[nando]

all 6 cylinder e30s are 14.5lb injectors.

etas are 19#, B25s are 14.5#. don't know about setas.

[Evan12]

all 6 cylinder e30s are 14.5lb injectors.

do whatever you can afford. but make sure you take care of maintenance before go spending $600 on a maf+chip conversion.

when was the last time your timing belt was done?

recently. as well as all my hoses etc. this wont be for a while, i am just doinf some research before i spend the money.

[Evan12]

Im going 19lb as soon as my injector rebuild kit comes in the mail. Ill let you know as soon as I get em in. I also have a Maf kit, intake and tune.

thank you thatd be great.

I installed a set of 0-280-150-415 (from an M50) on my otherwise stock engine with factory chip and you can tell there is a bit of a difference.

Do you have dyno data before and after?

Or at least 0-60 or 1/4 mile times?
