    Hi I'm new to this forum thing. I don't know much about it, let alone how to use it.
    I just want to know if a D15B7 motor will fit in a 1991 honda civic si (hb)?
    I think my head gasket blew and I was given a motor, but I don't know if it'll fit.
    I know it came out of a Civic ( about a '94) . I hope it does fit cause I'm tight on money before school starts.

    Anything?

    Well thanks for the response.
    What I'm tryin' to do is go the cheapest route. With the least amount of work I should say. without havin' to put a new computer, drive axle,Etc.

    So, no changing out the motor mounts? and everything will hook right up? I'll probly be doing all this on my own, so I'm tryin' to get as much info as I can.

    Ok so no one has said this yet I thought that I would let you know. The d15b7 is a obd1 motor so if you want to use that you will have to get a conversion harness to go from obd-0 to obd-1 if you would like to stick with obd-0 then you would have to get a obd-0 dizzy out of a d16 that is from a obd-0 car.

    he can use the intake manifold and distributor from his car.

    if you've blown your head gasket, why not sell the D15 and replace your head gasket and timing belt? you will end up with a much better engine and learn more about working on engines that way.

    helms manuals are availiable for download free or pick up even a chilton's manual for $20 it just involves some reading and carefully following instructions.

    anyway good luck, and dont forget to have fun.

    I would try to do all this on my own, but I'm on a cramped with time right now before school starts. I'm takin my family on vacation. Otherwise I am the type of person to try to dismantle and rebuild. Besides, the "SI" I have has a salvage title. So i don't want to dump money into it if I have to sale it one day, and nobodys interested because of the title.

    About an hour? I might try that. But don't you have to do the timing when you pull the head?

    yup. but if you can handle doing the head gasket by following a manual, you can do a timing belt just as easy;)

    +/- one weekend, depending on how mechanically inclined you are.

    In all seriousness, it's pretty straightforward. Get an accurate, quality torque wrench and a service manual (along with a standard socket set) and you should be golden.
