Alright guys i got a question for everyone/anyone. I did use the search and i found some stuff but i still didnt have a concrete answer. A friend of mine has a 1997 ek coupe with a 2000 B16B CTR motor in it. He did an ecu changeover to obd1, now the question is what alternator does he need? He's tried an OBDII Si alternator and hes still having trouble with high idle, gauges don't work, no v-tec engagement, so if you have any help with what alternator or what exactly is wrong i'd appreciate it. Thank You

 

99-00 si or 96-01 teg?

 

ya he tried a 00 SI and hes still having problems, but i just talked to him and he has the PCT ecu he didnt change it over, so that means its OBD2 so in theory a 99-00 SI or 96-01 teg should work..correct? do you have any idea what could cause the car to run like i said

 

Sounds like the ECU is fucked up (or the harness isn't grounding right).

Check grounds.

A 99/00 Si will definitely work because the blocks for the CTR and Si motors are the same

 

possibly in the wireing somewhere on the jumper harness from obd2-obd1...the wires might be switched around or plugged in the wrong place...i rmember when i did a obd2-obd1, a few of my wires were mixed up on the jumper harness

 

ya syndacate ill tell him to check that out, but since its not converted over from OBD2-OBD1 thats really the only thing that makes sense, but all CTR motors are OBD2 correct? and would it make a difference from OBD2A to OBD2B i really dont know much about the motor cause its not mine, im just trying to help the kid out

 

I've got a B16B in my 96 Cx. it idles high until all loads are turned off. like the blower fan, headlights, amps. it idles down a few seconds after.

 

ya he starts the car and it idles high, then after a while the spedo and the rpm gauge doesnt work, then the lights pulse, but im just making sure that a 99-00 SI alternator would work with a 2000CTR motor hooked up to a PCT ecu.? i feel like i am repeating myself but i just want to get this figured out

 

The alternator has nothing to do with it. I have a B16B motor & alternator and have no idling problems what so ever. It's your engine wiring or faulty ECU.

 

oh i know that, i was just asking if anyone was using the 99-00 SI alternator with a PCT ecu, and whether it was working fine, im gonna have him check the ecu and wiring

 

You will definitately be good to go with a 96-01 integra alternator or 99-00 Si and even the 96-97 DOHC del sol alternator will work, that is if the ecu and wiring from obdII to obd1 is correct.

And as for you 'Syndacate' don't spread misinformation if you don't know what you are talking about. The b16b (CTR) block is actually the same block casting as the b18c5 (ITR) block, but just destroked to a 1.6 liters. Do the research before misinforming fellow HT'ers.

EXACTLY what I was thinking.

Correction..the blocks are not the same. The B16b shares the same block with a B18c...the b16a has a block of its own...

To the OP:

I dont think its the alternator, i think the guys on here have it right when they are telling you its a wiring or faulty ECU problem...

 

alright guys thanks for all the help, when i get this mess sorted out maybe ill post something up for the future

 

i had the same problem. my car would do all of what u said ur friends car does. to make a long story short, i ended up getting my factory jdm alt rebuilt by honda, but they used gsr voltage regulator, and it wasnt producing enough current for the car to keep running. so i bought an ITR alternator and problem solved.

that was just my opinion ur friends stuation could be different. and i guess it doesnt answer ur question if the si will work. but at least u know the itr alternator works

and i really dont think the si will work.

 

Ah ****, my bad. I thought I read it somewhere as a B16a being the same as a CTR motor and I just re-consulted the source and it turns out it was indeed an ITR that was the same. I'm not sure where I got B16 from - my mistake. I apologize.

 

smoothCTR i appreciate it, thats what i kinda figured all along, and he just ordered one up yesterday well see if that solves the problem! we all hope so, i want to see that thing run again

 

no problem man . just let us know how it turns out

 

well as it turns out, the alternator was **** but the 99-00SI alternator does work in there, so props to people who told me that, but the main source of the problem was a corroded ecu connection becuase he has a water leak, so just to let everyone know how it worked out but its back up a working again, and thanks to everyone that helped out
