I called RacingBeatMazdatrix, RotaryPower and non of them have the template to do a MILD PORT. Only the Big Streetport. Well lucky me bacause the previous owner of my car did a MILDPORT in the old motor and when i took it apart i told myself that i can trace the port to a piece of aluminum sheet and do a port job myself to my new housings. I will trace the size and just use my judgement for the shape.

BTW i have a TurboII..im not sure about the N/A.

thanks if u could scan the actual size of the mild port template then post the pic on this reply would be great thanks

Atkins rotary might be able to help you out.

Buy the tempmlate! It will save you from having a pu--y motor.
The position of the port is as important as the port shape itself
remember NO sharp edges ANYWHERE make all you transitions smooth. Again buy the template once you are done you can sell it.
Please spend the few extra dollars and you WILL have a stronger motor. People take Rotary porting much to lightly, If you want real facts talk to an engine builder not the Forum. Take all info from forums with a grain of salt, there are alot of BS posted as fact. Talk to the builders- www.mazdatrix.com www.racingbeat.com www.pineappleracing.com Atkins.
Good luck...
