motor and tranny, 2000
new clutch, maybe a new flywheel, 600
get a new fuel filter, too.
get someone who knows what they're doin to wire the vtec solenoid, pressure, knock sensor and IAB. if you're brave enough, get an accord and prelude helms and do it yourself.
cost of motor and tranny may vary; probably end up being 300 more than my estimate.
difficulty is pretty low. no custom mounts, it'll fit the stock accord mounts.
good freaking luck.
