i was wonderign if i could do a street port on a NA and still keep all 6 ports, i want about 180+ hp to the wheels. i dynoed at 142 hp with the 6 port stuck open and the vdi kicking in late, i kno wif i fix those, which i am in proccess of righ tnow, i will then get about 155+.
anyway, does anyone have templetes on how to do a mild streeet port to get the power levels i am looking for? i still wanna have all 6 port! and dont wanna go with the 4 port side housings...also wanna keep the stock fuel injection system.. and this being a daily driver i dont really want it to be too loud...

 

Get the mazdatrix 6-port streetport templates, they are tried and true, I'm unsure of the power gains, but I think they will get you to your goal, while being streetable.

Mazdatrix says to go with the TII rotor housings because you can port the exhaust easier, while it's easier, it's not required, you can drill the pins out on the exhaust diffuser and pull it out and port the exhaust and the put it back in with new pins. Check out mazdatrix's website, they go into major detail.
