2012 Mazda RX7?

I know first hand that the transmission on an FD is super light compared to a T56 as I was able to pick mine up easily when I installed a new clutch and my friend has a WS6 for the T56 comparison and that is a beast compared to the FD's. However I know the weight difference between the 13BREW and the LS1 is very minimal as I stated in my post before the rotary uses all iron housings so it weighs more then it should for the size. This is why I believe using aluminum housings will seriously help the motors weight and the the change in the stroke length on the 16X might actually mean a rotary that produces torque for once without having to get 3 rotor or even 4 rotor if you're rich.

I'm currently debating whether to drop in an LS1 or not as I've gone through two sets of turbos on my FD in 5k miles but I'm hoping to just sell it as a roller and move on to a more reliable platform.
