D16 block with B7 head?

I currently have a D16A6. well the head is warped and I can not find one anywhere. My friend has a perfectly good used B7 head with around 60k miles on it. Will I need to do anything special to do this swap? Anything need to be rewired or will the distributor bolt right up and connect in? I just need my daily back. Gas is killing me.

    im pretty sure it will bolt right up. the only difference is the injection system and stroke between those motors

    so will the vehicle run if the only thing I swap is the heads? like a straight swap complete head for complete head. nothing else. all original parts like distributor, intake manifold, exhaust manifold, timing belt?

    You might need to swap your complete D16A6 intake onto the B7 head. What's the B7 from again? Is it a 92-95 Civic head (MPFI) or an 88-91 head (DPFI)?

    this is what u need to do

    remove the A6 head, install the B7 head
    use the intake manifold from your D16A6 on the D15B7 head
    put the D16A6 cam shaft into the D15B7 head (this is because D15 cams are indexed different than D16 cams. if you use the B7 cam you will either be half a tooth advanced or retarded depending how u install the belt. BUT!!! if ur D16A6 is from an 88, you can go ahead and use the B7 cam if you want as 88 A6's were indexed the same as D15s.)

    bolt it all up and off you go!

    the B7 and A6 heads share the exact same casting. so swap the cam and ur good to go.

    dont forget if you are still obd0 u may have to use the dizzy from the a6 if you go that route. the obd1 b7 dizzy may work, but im not sure if they have a diff. plug or not. hopefully that helps a little. definately use the a6 intake manifold as stated above, good luck!

    I just did this same swap. had to use obd1 dizzy and no matter how many times I reset the timing its always off after a couple rotations. Is there a different timing belt I should use. Or easier to swap the entire camshaft?

    Maybe an adjustable cam gear?

    what cam are you trying to use and on what block?

    93 b7 head on a6 block.

    use a d16a6 cam and a stock cam gear, or use the d15b7 cam plus a 96-00 SOHC cam gear.



    the d15 and d16 cams are indexed differently to compensate for the 5mm deck height difference between the d15 and d16 blocks.
