1st Gen/RX8 motor/trans install

I guess what I'm thinking is this - I've seen wrecked rx8's for around 6k,low mileage, undamaged drivetrain. Mazdatrix sells a ported 13b w/12a ends (drop in 1st gen) for about the same money. More work to part out the rx8 but you get a 6 speed too. How much HP is intrinsic to the rx8 motor and how much comes from the engine mgmt. sys.? Would a sidedraft setup diminish output that much?
