I have a s1 Rx7 with a 13b pp with carbon seals looking for more power .
It has standed rotors (weight wise) and with 46mm x 50 inlet port.
Q . how big can u go with the inlet port size with out the seals jumping out the port. and lighting the rotors and weights??

I know some 12a PP race engines use a 2.25'' hole in the housing, with a 2'' I.D. pipe in the port. Since that's on a 12a, you might be able to run a little bigger port on the 13b, not sure if the apex seals would bend in the middle with a bigger port or not.
