    Hardest part is probably wiring.

    With the correct axles(go with 90-93 integra axles and midshaft), quality mounts/shift linkage(hasport.com), it's a simple bolt in process.

    Even the wiring can be as easy as 'plug and play', but your going to pay for it. Rywire.com and Boomslang.us carry conversion harness' that make life so much easier.
    You only need to wire in VTEC, 2nd o2 sensor, Knock sensor and IAT for the swap.
    (its only 8 wires, which are all prewired to the ECU conversion harness and color coded/instructions provided for easy installation, so don't be scared...)

    Just make sure when your engine is out to pound out the wall where the alternator is going to be, or you'll have the problem like i had where i had to pound out the wall while the engine was sitting in my bay.. =/

    Send Rywire your stock harness and the GSR harness and he'll merge the two into one, and it will all be plug and play. It's about $300, but if you are scared of the wiring, do that.

    Otherwise, just get the ECU conversion harness, and do it yourself. All the instructions are provided with Rywire. Then pick up a P72 ECU.
