Tell me if I get what you are saying. You are saying that if a car didn't come with the option of a turbo straight from the manufacturer, that's die-hard proof that the engine can't take a turbo? I have a feeling Mr. Shelby and Mr. Lingenfelter might disagree with you there.

Go talk to the guys on there. Many of them have been running forced induction on D and B series motors for years. They'll reassure you that it's OK to run boost on a honda.
Honda didn't offer forced induction on their motors because 1) it would drive up the cost and 2) it would drive down the gas mileage. They built their reputation on building relatively inexpensive, reliable as hell cars that sipped gas. Boost would violate that formula. Arguing that you can't do it just because the manufacturer never offered it is circular. By that argument, I can't put a performance suspension on a mustang because they never came from the factory with that suspension. I can't use a K&N filter on just about any car because they don't come from the factory that way. No synthetic oil either. Oh, and you can't EVER run nitrous because there aren't any cars that come from the factory with it.
Point is, just because they didn't offer it doesn't mean it can't be done.
Might wanna ask your honda gurus if they're avoiding boost just because they think it will grenade the engine (it won't IF they're not stupid about it) or because it would disqualify them from the class they're racing in. They ARE racing, right?
