Just wanted to know if I just get the long block(h22a) can I just use all my other parts for the accord engine(94 accord ex) to make the swaps complete or do I need everything from the h22a. I have the p13 ECU already.

 

real quick.... You could still use your stock Accord tranny. Though keep in mind that the Accord gears are spaced out considerably more than the Preludes. As for an all motor application you would want to get an H22 tranny. If your planning forced induction keep your tranny for sure, perfect for a turbocharger/supercharger.
