    Yes, the 88-91 Si transmission will work. The ecu and distributor depend...easiest thing for you to do would be to convert to OBD1 and use a P28 ECU and OBD1/newer D-series VTEC distributor. If you get a complete Y8 swap you can use that distributor with an OBD1 ecu. Whichever distributor you go with, you'll have to wire it into your stock harness. You will be able to keep your stock starter/alternator. The only other thing you might run into would be your injectors, and your best bet is to keep your stock injectors (if it's already a multi-point civic). All D-series injectors are the same size, and it will save you wiring to just keep your stock OBD0 injectors. You'll use your OBD0 mounts for the swap, and you'll have to keep the driver's side motor mount bracket that bolts onto the block from your stock OBD0 d-series.

    only if you use the crankshaft pulley from the 91 - the Y8 crank pulley is for a 4-rib alternator belt and the 91 alternator uses a 3-rib belt

    watch out usin p28 on y8, engine will run fine, but ignition timing will be off no matter what you do, y8 cam gear is indexed differently than z6 cam gear.
