    Default 1998 Prelude Motor Swap

    Ok I purchased a 98 Prelude Base Shell and have an H23A1 and H23 Tranny ready to go in it. Just need info on which motor mounts to use, and axles. Am I correct in thinking that like the older civic crx swaps i'm used I need to swap the OBD2 dizzy guts into the H23 OBD1 dizzy? Any other wiring changes I need to make? Sorry the last swap I did was atleast 5 years ago when i rebuilt a B20b for my crx.
    Thanks for any info

    You'll need the crank sensor converter harness from Rywire, an obd1 internal coil dizzy and a chipped ecu and a conversion harness for the ecu, if it's an obd1 ecu to an obdII harness.

    This is the h23 vtec, right? or just an H23?
