Anyone port there own engine?
Has anyone ported there own intakes and exhaust? I was considering going Street port and doing it myself but I wanted to ask some questions about it first.
1. Can you **** up the housing if you don't grind it down perfectly to the shape and size of the template?
2. Do I need a micrometer to make sure both rotor housings are grinded exactly the same depth?
3. What else do I need to beside what is at this mazdatrix site? http://www.mazdatrix.com/faq/portintk.htm
4. What else do I need to know about porting so I don't **** up my ****?
I also want to do a poll about ports, just to see what you all have. I know there are a million polls about this but I don't care, I want my own poll

1. Yes, you can but as long as you don't touch the inner edge of the port you should be ok.
2. You can't actually measure the extent of porting you do to the runners so it pretty much comes down to experience. Basically you want nice smooth transitions from the outside of the port into the runners.
3. Nothing I can think of.
4. It would be a good idea to get some junk engine plates from somewhere to practise on. Then when you feel confident enough you can attack your good motor. That way you can also work out how far you can port without breaking into the water jacket.

1. As long as you dont touch that inside edge you'll be cool.
2. Nope, it will still run just fine if you dont, port flow will differ though.
3. A template is all you need, and the right tools, then get to cutting.
4. Don't cut too deep, velocity will suck. Oh, and dont even bother trying to port without carbide bits, it's a waste of time.

So I can do the top, bottom, and outside, but NOT the inside; the inside being as if I was going toward that hole where the ecentric shaft passes through, right? I know, sounds stupid, but I got to ask. Oh, and what are the runners, those round and square holes where water goes through?
By the way, thanks for all the info guys.

Hell yeah, if you grind any at all towards the e shaft, its trash!
But this isnt just as easy as just get a dremel and start grinding it dont work that way... The slighest difference changes all the intake timing of the motor. You need to be very careful and know exactly what you are doing unless you got about 3 months and 4 or 5 spare perfectly good motors to ruin...TRUST me ive been there...
