if u are buying a motor and planning to turbo it...the single most inportant piece of advice i got for you is BUILD THE MOTOR BEFORE YOU SWAP.
you have to remember that building an engine is 10 times easier when its on a skid in front of your garage (engine stand is better).
the h22a/1 has FRM lined cylinders, i give your turbo h22 about 10k miles with no sleeves before oil consumption becomes a problem.
SLEEVE BLOCK
RODS/PISTONS
CAM GEARS (solves your VTEC overlap tuning issue)
easy, your done

cam gears can be used to dial out overlap on a dyno
the amount of boost you can run on a "built block" is determined by intercooler capability and fuel setup. if you run big injectors and solid intercooling than you should have no worries about detonation.
this is also very dependent on tuning.
id say the block itself would be safe to over 13 psi. thats a ballpark figure too.
higher boost doesnt necessarily mean danger to the motor, if the motor is built correctly.
again...detonation can destroy any motor, built or not. tuning and fuel management are the 2 important things for safety of the engine.
