    In searching for an engine to replace my Y7, it seems that there are really only D15's left. But the list here in the reference area doesn't show an OBD2 D15 engine. I don't get it. I want to stay OBD2 for ease of swap. Are there OBD2 D15's? My supplier has them in stock 10 miles from my house and I want to start my swap this weekend.
    Thanks for any replies.

    Because I want to make sure I know exactly what I'm buying. When a seller says he has OBD2 D15's and I see no OBD2 D15's in the engine list here I start asking questions. Wouldn't you?

    i believe the only usdm d15 that's obd2 that you'll find in the states is the 3 stage vtec d15b. it would be a hassle to wire up and all for a slow ass super economy motor. If you can't find a y7 then convert to obd1 and find yourself a nice d15b7. should be able to get a p28 and ecu jumper for about $100 if youre a savvy interwebz user

    The 3-stage D15B VTEC is not USDM. IIRC, it was only available in Asia.

    It's really seeming smarter to just rebuild my Y7 rather than try to make a D15 work in my car since it's just a commuter for me and not a car I'm trying to race with. Thoughts?

    just buy a new y7 instead of rebuilding it?

    thats seems easiest to me.

    What exactly are you looking to do? Just a simple engine replacement, better economy, etc(in other words, why do you want to swap the Y7 out)?

    The car has 260K on the clock and burns a quart of oil every 150 miles. Other than that, it runs perfect. It's my commuter car and gotta stay smog compliant for Cal. I was hoping to do a swap to a Y8, and even snagged an ECU for a Y8, but Y8's are rare now or high mileage. I'm doing searches here and at Dseries.org and shopping engines like crazy. I wish my car was OBD1 as those engines are plentiful. It's been fun trying to compress a couple years of engine swapping knowledge in to a week. lol

    I guess my big problem here is, the engine market is loaded with OBD2 D15B's for 96-00 Civic's, these are VTEC engines. The closest motor in the engine list would be the 1991-1999 Civic VTi (EG4). Is this what the sellers on ebay and the engine shops are selling? Is this a good swap engine for my car? Just get the ECU for that car and wire VTEC?

    The VTi engine should be closer to the D16Z6; which is more common than the 3-stage VTEC engine.

    The 3-stage VTEC D15B is a good engine(gets good gas mileage and yet still has some power), but I'm not sure if the ECU would throw a check engine light(hopefully someone can chime in).

    Does your motor have a knock sensor? If not, it may be possible to swap in an older non-VTEC motor and get away with using the Y7 ECU for inspection. The main thing I would be concerned is, if you can't tell, is inspection(especially strict states like California).

    I don't know if my car has a knock sensor. It's a 97 LX. I looked in the ECU list and couldn't find one for the VTi. So I have no idea which ECU would work best.

    Y7's do not have knock sensors.

    Talked to my local dealer and ended up bringing home a D16A, non VTEC. Looks exactly like my Y7. Fun weekend ahead.:D

    lol good luck passing smog in Cali with a D16A. From what I've heard about Cali is that you can put a newer motor into an older car but not vice versa.

    I searched the intake manifold part number P2F and the gasket for it relates to 96'-00' Civics and Del Sols. I'm pretty sure it's a JDM Y7, which means it's almost gotta be OBD2. So far the only difference I can see is the exhaust manifold has no cat hanging from it and only one O2 sensor on it, which doesn't matter because I have to swap my two sensor exh manifold over for it all to bolt up.
