I wouldn't. And I say that not really because of the cast pistons and cast crank, but also because your already at about 9:1 compression with a fast burn chambered head.

Not to say it cant be done, and if I was to do it, I wouldn't exceed 3-4lbs of boost, and I would expect the worst and hope for the best.

In the end, theres lots of ways to ''try'' to make power out of what you have, but sometimes its better to start from scratch and use good solid parts from the ground up.
