I realise youve got the motor for free but a B18a is not a worthwhile swap...Its got alot of torque but only slightly more hp than a ZC and much less than a B16A...theres a thread on here from 2ndgenIntegra (or sumthing like that) on why its not a good idea to put a VTEC head on a B18a motor.
For all the extra expense of getting the ancillaries and the hassle of putting the motor in, your better off gett a ZC or a B16A
