How much power increase are we talking about Greg?
There isn't alot of data for a 13B in STL, only Flatout has built one and raced it competitively in majors.
Do you think a port matched 13b is going to make more power or torque than one of the restricted 2.0L engines?
Honestly, i see the rotary as a cost effective engine choice for STL Mazdas. IF this port matching proves too powerful the weight can go back up, or run a FPR like all the other "too powerful" engine choices.
I am heavily leaning towards a rotary powered STL miata. Engine cost is low, power is high, reliability in race conditions is high.
