EVERYBODY knows that a turbo B16 will stomp a turbo D16.
However, a D16 is a dime a dozen. Blowing a D16 is less heartbreaking than a B16. For the $, I'd rather have a SOHC turbo + extras, but that's just me. This debate is getting old as ****. It's like the Domestic vs Import debate. Do what you like and I do what I like; I'll just see you at the track where it matters.
I'll put it as my friend put it so well: "I'd hate to spend the money on a swap and then get stomped by a SOHC. That'd be embarrassing."
