I dont' know how to tell, and I've searched and coem up empty handed except for FS and WTB threads. Help guys, how do I tell if these are real prelude injectors? The guy I'm about to byu the from says that RC ENG. told him to check the voltage and he did and it was correct for preludes. I beleive him, but is there something more positive I should do?

cmon ya'll, bump

 

well do the clips plug into an obd1 car? or do they plug into an obdII car? try that!

 

well yeah, I mean, they're derfinitely gonna be obd1 if they plug right in, btu how do I tell if they're from a prelude?

 

as far as i know the obd1 integra injectors dont need a reisistor box and if you measure the ohm resistance they are liek 13 or so... these plug directly into an obd1 so you know they are obd1 as for the ohm resistance they are low i can measure agian but they are like 2-3 i think so they dont belong to integra.. thats why i say they are prelude injectors and the guy that i bought the injectors from also told me they were prelude injectors. RC engineering said to measure the resistance to confirm .... please correct me if im wrong peopel

 

keep in mind there are many differnet prelude motors as well, if your loooking for the h22a 340cc lude injectors, all the ones i've seen have a green tip on it, but I am not sure if thats what marks the size of the injector. the only sure way to find out is to flow test them

 

according to rc engineering all obd1 preludes requires a reisister and i think they flow more than the b series injectors. the only preludes that dont requires a resistor are the obd2 97-2001 prelude but then you have to change the connection to make them work on civics.

 

ok, I'm convinced. payment is being sent bro

 

On the OBD1 prelude peak and hold injectors they have a green tip as well as a small notch in the clip(in between the two metal prongs). A B-series OBD1 injector also has a green tip, but in the clip, they have two notches on each side. Not to mention they are saturated(high resistance) vs. peak and hold(low resistance)for the Prleude. This can be tested with an ohm meter.

In regards to OBD2 injectors, it's hard to tell the difference between B and H series visually. They are both saturated(high-resistance) and will have the same ohm reading and have the same clips. The tips might be different in color. For instance, a 97-01 Type-R has orange-like tips and a B16A(99-2000 Si) has a brown tip.

Here's the rundown on the cc's of Prelude injectors:
92-95 Non-VTEC peak and hold 240cc
92-96 VTEC peak and hold 330cc
97-01 VTEC saturated 280cc

Hopes this helps.

so which car do these injectors belong too. they are different from my gsr injectors.. the ohms are 2-3 low so they are peak and hold and they fit obd1.

its not 97-2001 lude becuase those are saturated injectos

thanks

He his right! I have a set right in front of me(OBD-1 H22 Lude injectors) and they have green ring gasket right below the filter and one notch between the metal contacts where the plug clips on!!!

 

I will gaurentee those are not prelude injectors, prelude injectors for 92-95 have a olive tip

 

ok the prelude injectors have a green ring? ok the picture that is up there might be my other gsr injectors then ill take pics of both. as for prelude injectors have green tips i dont know.. all i know is that they cant be integra injectors because the ohms are to low. i might have my injectors mixedup ill take more pics and post them up

 

can anyone take a picture of a obd1 h22 injector??

 

ok here are the pics of the injectors with green ring

are these the prelude injectors then? i had two sets so wasnt sure which was the integra and prelude

 

uppppppppppp

Yes that looks like my H22 injectors! You just need to clean them now.

 

ok i had the pics of the wrong injectors..

 

can anyone confirm what flow rate these might be..

 

those are still not prelude 345cc injectors, the TIPS will be olive not the o-rings, there probably peak and hold accord/civic injectors.

 

arent all integra /civic 92-95 civiv and 94-2000 integra saturated injectors??? high ohm resistance. as far as i know all obd1 civic and integra injectors are saturate high ohm resistance injectors so i dont think these are integra or civic injectors from obd1.

anyone want to confirm that.. that was the info i got from rc engineering

 

yes but obd1 and obd0 use the same clips, only obd2 use different injector clips

 

ok what year lude is it and is it h22 or h23 or f22 92 ludes with h23 and f22 are a 240 cc obd0 same as an integra and civic si also 88 to 89 teg and they are a un saturated injector meaning they use a resistor box now my info is only on a 92 lude because ive battled with the stupid money hungry pos for over a year but other than the dumb knock censor being the problem i dont want to burn it any more but if im wrong about the saturated part it might be the other way as in unsaturated now the h22 are an obd1 but they also require a resistor box meaning obd0/obd1 preludes are the half breed they are 1/2 obd and 1/2 obd1

sorry if i confused the hell out of ya but maby i helped a little

 

ok i really looked at those injectors and they are h23 injectors or obd 0 same as a 1.6 1.8 integra and same as a b series obd0 or even obd 0 b16 i have an obd 0 b16 injector right in front of me and whala an exact match

 

hi i was wondering if you guys can tell me if these came from a 92-96 prelude h22 vtec??
