what does it take to port your own engine? I saw a pic on here of a guy doing it with what looked like a dremel style tool.

 

no that is a compressed air powered dye grinder (i think). it isnt recommended if you dont have experience with it. dont just go grinding away

If you decide to, buy some templates.

Dremels work pretty good too! I did my exhausts with air powered metal-eaters, then did the clean-up work and all of the intake ports with sanding rolls in my Dremel. Strangely enough the sanding rolls removed metal better than the carbide burrs I'd bought... go figure!

 

the pic you saw was probly me. with the rotor shirt. I can't tell you it is easy I have ported heads for along time. So I have my feet wet just remember just blend and use templetes and don't inlarge the port it is already pretty big just blind and polish the port. I was doing the work on that motor because my friend went through the waterjasket so don't go wild.

 

I am biulding a site on my explaination of porting to give an idea of what to do and what not to do. I will post it when I am finished.

 

Ah.. just go look up porting somewhere on here youll find some pics, with measurements... or maybe i found it on some other sight... Anyhow what i did was measure it with a jiffy marker, and follow your outline... its easy as pie....

 

There are too types of "die grinders".&nbsp One is the air compressor one - the other is the electrical one.&nbsp I prefer the air one, cause it's lighter and cooler to use.&nbsp The electrical one is rather heavy and cumbersome (unless you get the flex extension for it).&nbsp The air die grinder is hella cheaper too - under $20, but you do need an air compressor to run it.&nbsp Electrical die grinders are easily over $100-$150.&nbsp These are all 1/4" collet types which take the industrial standard 1/4" shank carbide bits and grind stones.

Dremels are good for the first time user.&nbsp Although the bits are rather expensive, the small size keeps you from causing too much damage from screw-ups.&nbsp I guarantee you the bit is going to pop out of the hole and skip all over the side housing...
