But are you looking into a Turbo or N/A set up? If you are going down the Turbo path, I don't see the value of stroking it as well (As nice as it would be :D ) The gain from the Turbo set up alone, even if you keep it conservative would be substantial. Increasing displacement would be a very costly exercise but perhaps wouldn't give the power gain to justify the price. Just my 2c :)
