with my dremmel tool, sevral bits, and some time.... looks pretty good to me.

yes?

what do you mean?

 

take off too much material he means.

Hard to tell a good port job from a bad port job with pictures.

to you tho

 

ehh its my first attempt, i dont think i could F it up too much. just smoothed out the ports to touch. Didnt like that rough casting too much.

 

It's always not a good idea to get rid of all the casting marks, its there for a reason... mostly to help atomize the fuel and air.

 

Reputable head porters don't polish the ports until they're completely smooth.

I got my head back from Alaniz a couple weeks ago and you be suprised what it looks like.

It's pretty easy to mess up a head by going overboard with the polishing or removing too much material. There's always the chance that you might loose horsepower.

I gotta give you props on doing it yourself, though.

 

Did you trace the gasket boundaries on the surface of the head before doing anything? Did you just touch it up or did you actually grind material off?

 

i dont think i would have the ***** to port my head with a dremel... lol but for you.. looks good .. hope it works well

 

props to you man . ive got a couple extra heads lying around that i plan on trying some diy porting on. how long did the whole thing take?

 

you got ***** man for doing it so i hope it works well and get us some after information on how it works now better or worse? OKAYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

 

try and find a place that will help out with flow numbers so each port is equal or very close....then go from there to see how much work needs to be done after the numbers are found out

 

when Doing a DIY porting. you dont want the intake ports like glass smoothe. You need a lil rough surface to help mix the fuel and air together. but the exhaust ports should be like glass. for your effort. now get it flowbenched and see how you did

Oh that probably wasn't a good idea. From what I was told the ruff texture is there to keep gas from condensing and forming droplets. Should probably rough it up again.

 

Its too smooth, its suppose to have a ruff texture to help atomize the fuel. You can check out for help on how to port a head.

 

thanks for the comments guys

got a lot of ppl asking how i did this with my dremmel.... so how about a small write up.

I went out and bought a 12v dremmel with 4 speeds. 7000 rpm, 10,000 rpm. 12,000 rpm, and 14,000 rpms. I saw what bits it came with, and put them to work. The first bit was pretty much a sand stone. It ground off all the rough casting, i got rid of the marks on the side and generally just smoothed it out. I had sevral sand stones, one was cone shaped, one was round and one was a cylindar. I kept the rpm speed up at 14,000 to get the cast flaws off quick. the little bits kept braking off, so i went from the cone, to the round, to the cylindar... and the cylindar is the only one left that survived. I know you're suppose to keep it on real low RPM's but... **** it, im lazy.

After i ground down the casting so it was fairly smooth, i got the sand paper bit out and secured it in. I set the RPM's down to about 10,000. I smoothed it all over agian so it was smoother to touch.

Next was the wire brush bit. Its a spinning wire disc (be careful, a couple of the wires wound up in me and my GF's feet. i recommend NOT doing this in your appartment). I used the circular wire bit to smooth out the rest of the ports, this gave it a pretty nice shine.

Last I took the polishing bit... kinda like a ball of cotton. and went over the rest.


Yes, this is a very half ***'d P&P job, but it looks pretty good to me, i think im gunna go ahead and take you're advise and rough up the ports a bit. Use my sanding bit to do it.

thats where i got the idea to do it myself... didnt read the whole page, just skimmed though it... figure i cant F it up too hard, so why not? Im going to be replacing the valve guides as well, i chizzeled away at them a bit while trying to get into the small areas

 

every port job that i have seen on the intake side look like someone bead blasted the inside.. Its all smooth but has that texture to help atomize your intake charge ( air and fuel ).

 

you do know that you'd make more power for a GOOD valve job and a little bowl work, correct?

port work is usually a waste of time for mild/stock engines.....

just so ya know

Exactly, good effort though.

possibly like this ?







-ninja edit- lol its my engine btw.

 

You guys are on crack.

How could you possibly relate porting a D series head (worth maybe 50-200$) and bravery?
