I think they are 24lb/hr, which roughly translates to 250cc.

yea ive heard 240-260, nice thing is with a 2.4 you can use the injectors from the GM supercharger kit they are 310cc, im sure if you search around enough on them you can find the part # for them they are a direct swap, they might dump a little heavy without the juice so you prob need to get an apexi safc to trim some fuel and get it right <br>

I believe the low impedance from 95 to 99 are 24lb and the newer ones are 190lb high impedance. I was using the injectors out of a 2.3 H.O which are 310cc on my 2200 than it was running a little rough than I switched to the 2.3 L.O injectors (210cc) and it runs fine without turning down the pressure.

190 lbs?

I hope that is a typo. The injectors are the same size from 95-99 and 00-02.

Sorry I meant 190 cc and I was pretty sure that when the switched to the high impedance they made them 190cc. Also I can be wrong about this.

what is the lb rating on the 2200 stock injectors?
Re: stock injectors

2200 ohv have 19 lb/hr stock injectors.

yes, shifted. the 2.4 are 24 lb/hr. both engines also have high impedance.

I 'm getting ready to put a set of 2.4 injectors into my 96 2.2 with a S-AFC II controlling them on a custom top feed conversion. We'll see what happens. Should be done by the end of March.

so how would the 24# injectors out of a 97 lt1 act alright in the 99 2200?
Re: stock injectors

if they fit the rail and harness, they would act similar




Re: stock injectors

damnit we need an edit/delete button. i meant they would act like 2.4L injectors. same flow rate. would have to have some fuel trimmed off probly to make it idle right.

Nope, 96-98 are all low impedance, 99 has both, 00 and up are are all high impedance.

yea. i meant to say 00+ are high impedance. just left that part out. thanks

how can you tell the difference between high impedence and low impedence? I have a 99 model engine and trans in my 97 rs.

measure the resistance across the injector plug with an ohm meter/multimeter. high impedance will be around 12-14 ohms.

this may be a stupid question, but i should measure across the terminals on the actual injector?

Yes, as long as you unplug the clip first.

The high impedance (skinny injectors) used in some 99's and all of the 00+ 2.4L's are different flow rates. I had my high impedance injectors sent to RC Engineering for balancing and they were around 190cc if I remember correctly. In fact, they have been even lower. I think the 95-98 were between 240-260 cc.

is there any advantage to putthe 22 or 24 # injectors on a bolt on 2200? I have access to both. Just curious as if it is worth the time. i will be spraying soon also. If at all i will put the bigger injectors in for that.

This is what I believe to be correct as well, the 99+ high impedance injectors don't flow as much as the earlier ones.
