I sitll think you are better off purchasing a H23 VTEC motor that is OEM and unopened. Drop it in, and part out your h22 motor.

you can sell the block for $200 the Head for $300-400, etc.

A used motor, burning oil, that had nitrous on it, its not simply easy to rebuild. If the Bore is out of round (because it probably will be) YOU CANNOT REBUILD IT, the motor will always smoke unless you decide to resleeve it ($1000+)
