Injector questions

[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.

[Kershaw]

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.

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

[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.

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?

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

[Evan12]

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

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.
