Port and Polish

**mag_pbg** · 05-14-2004, 08:02 AM

Would it be worth it to take a head off of another 3geez and have it port and polished at a machine shop, and how much would it cost to have it done¿

it would be better in the sense that you dont have much downtime with your car while its being done. The only downtime will be when you change out the heads.

as for how much it will cost, you'll just have to shop around and see who's lowest.

Talk to sean about it. He's been putting alot of time into my head and has managed some unbeliveable flow number from it. The head will break 200hp no problems with a cam and stock interals.

What does porting and polishing involve completely?

i got my head P&P and bored out with the bigger valve setup, 3angle valve job, and intake P&P and port matched to my head all for $800

Was your engine already taken apart or did they pull the parts for you?

**86LXItooFAST4me** · 05-14-2004, 10:53 AM

pulled them myself

quick question from the moron:
is it practical to P&P if you're turbocharging, or is there no point?

P&P on a turbo car is extremely practical. The easier the air flow, the better.

oops, next post

**86LXItooFAST4me** · 05-14-2004, 12:48 PM

hell yeah port it! P&P just makes you air intake ports larger and smoother, meaning you have more air and also it will be less friction

just checkin'
don't know i thought it might not be... (slaps self in face)

Or you can try it yourself. I have done it before on a few heads. All I did was a basic P&P to clean up the factory casting with a Dremel. You won't get anything promising like what Sean offers but it will help and it is really cheap.

Justin86, I think I would rather do it myself, so any info on how to do it would most appriciated.

**HondaBoy** · 05-15-2004, 03:54 PM

well, this brings up my point of what you first stated. would it be better to take a head off of another 3gee? well i think yes, thats a great idea. i'm going to do that hopefully in the summer. i wanted to get a local performance machine shop to work on my engine, but they want the parts taken off by me. because my 3gee is my daily driver, i want it off its feet as little as possible. so i wont be tuning the original head first. i'll get one from a junked 3gee, but i'll also make sure its in good condition before buying it. my local shop has built some of the race engines for local car teams. i'f you have never taken a head off an engine, you might want to read up in a service manual first so you dont end up warping it by taking the bolts off incorrectly.

I have a ported and polished head. All i gotta say its DO IT. i mean u well tell one big ass difference i tell u that much. U get more air and which = more tq and hp. Once i had that done i got my piping to 2.5 and a highflow muffler. Just plain in simple Get it done. U well love it

**mag_pbg** · 05-16-2004, 06:29 AM

Allright you al have me convinced lol, but does anyone have a step by step guide to port and polishing at home¿

**HondaBoy** · 05-16-2004, 10:25 AM

personally i'd be afraid to port and polish myself. although, that would save some money. i'd hope someone here can help you out with some instructions.

**Justin86** · 05-16-2004, 10:42 AM

What you need is a basic cutting kit which will have your cutting stones and a polish kit. Use the different stones to clean up the factory inperfections. The polish kit will have a sanding wheel with fine sand paper, then you will use the stone finish wheel it has, third use a wire wheel (this will give you the polish look), and last use the buffing cloth wheel and the polish compound they supply to get the finished product.

The IMPORTANT thing you need to know is becareful around the bowl area (where the valve seats). There will be a steel insert (aka. valve seat) and you don't want to take too much off here, just a very little bit to clean it up with fine sand paper! If you take off to much the valve won't seat proper. I suggest doing a google search, you can find a lot of help ful tips online and bits to use.
