I just swapped a JDM low mileage B16A into my Integra, so that I can complete my LS/VTEC build. I had problems with it not engaging at first, but that is fixed now. I had the wrong wire running to the solenoid. But now, I get a check engine light 20 when I take it past 8000 and Vtec disengages.

When Vtec engages though, it's very quiet and can hardly notice it. I wanted to know if this was the way it was since I've never run a B16 before. My friends tell me it should be more noticeable.

Any ideas or remarks?

I know a stock airbox/exhaust can take away from the sound.

Unless you have other engine problems or its just not a strong motor.

I have intake and cat back. Not loud at all. Really need to pay attention to notice it engages. I guess I rode in a GSR that was that way too.

I think the motor is pretty good. Runs great and low miles. Plus it JDM and has never been disassembled.

you should be able to hear a noticeable change on the JDM b16 around 5700rpm. its actaully pretty loud

jizno

it should be louder than what you are probably hearing, mine is ear piercing on dynos

That's what I was thinking. I don't know why it doesn't engage hard. I can hardly tell that it's there. Don't know.

how's the oil?

DAguyLS

yes, vtec will not engage if your oil level is low

what ecu are you running?

its not suppose to be a harsh thing, unless you're a dumbass and set your vtec point way out of range. Its SUPPOSE to be smooth.

Did u put a JDM B16A longblock or complete swap...? If it was just a longblock it could've been an automatic B16A which had weaker cams...

DarkTeg94

I'm running a socketed P28 w/Skunk2 chip. Oil level is good and I double checked the wiring.

I didn't know about the automatic thing though. Good possibility that it could've bee auto since it's just the longblock. Any way to check that?

Where would an auto B16 come from?


And my impression was a smooth crossover indicates a healthy motor and the perfect engagement point.

jdm civics and del sols?

Yea forgot about Japan!!!! Still like I said before, I think its ok that it doesnt "crack" vtec but crosses smoothly. I think your better off.

When u installed the tranny, did u have to install a five speed flywheel, or did it already have one...?

DarkTeg94

When I bought it, it had no flywheel. I had to swap all that over. More than likely a auto then?

I have owned numerous JDM hondas with B-series engines and they were all dead of themsleves when the first arrived in my country...some took a few days to liven up, others took a few weeks. The engine has been laying for god knows how long and it basically needs to be run in again, so give it time, it should come round after a short break in period

2 years ago when i sat in a Sir eg sedan (I live in New Zealand, its was my friends car), yeap with just an airfilter and straight through exhaust with no cat, at 5700 you could hear it scream. it redlined at 8.3 or sumthin up there.

BoostinEJ1

only reason i asked is because this kid in my town has a jdm b16 in his car and said stock cross over was at 4900

vtec crossover depends on ecu...should be 5200rpms if its stock, but you said a skunk chip so who knows...but a B16s vtec crossover should be very well heard. like others said it could be an auto

5,500 RPM if stock....thats just my kirked out ECU that makes it hit at 5,200

i have a 94 civic coupe ex/si with jdm b16a swap with full dc headers and exhaust too the back and a cold air intake and a socketed/chipped p28 ecu powering it and my vtec kicks in at 4200 rpm and it is loud and powerful very noticable if your is quiet check oil pressure and vtec sylenoid also try first throw 1 bottle of octane boost and a bottle of vavoline injector cleaner this fixed a prob i had
