a CRVtec motor with the stock bottom end with a turbo is just asking for it since the B20 motor was never designed for the high revs with the vtec head also it lacks the oil squirters in the vtec block and to add 15lbs of boost into the mix is a accident waiting to happen. if this was my car the vtec head would go just run the B20z with the turbo and have a programable OBD1 ecu and have it dyno tuned.
