The 1NZ (and 1ZZ and 2ZZ for that matter) have far to big of a stroke.... you need a more square bore and stroke.
destroke the 1NZ with custom rods and pistons and offset grind on the crank and shave a bit of the top of the block off ;) Then you can make some serious power but you'll also lose a bit of displacement. But well worth it for the performance gain. But not worth it in the wallet.

I still know this guy, and we still talk about doing it. Went shooting with him last week. Maybe one day?
