He said its an 01 cougar? Not focus, is his focus named "cougar" I'm confused, an 01 cougar curbweighr is 3200-3500 3200 for i4 3500 for v6. But again i could be wrong and he said cougar for no reason. Thanks

[ner_das_uc_k]

Its a 2001 cougar with a 2.0 zetec and n my door jam the curb weight is 2800 and even online it says 2800 Idk where everyone is coming up with 3500

[StephenElsbree1986]

Its 2892 lol basically 2900 idk but i was stuck on the v6

ah whoops i missed the cougar part. when you go to buy any parts for this build you need to make absolutely sure that they will work with your car. i am not sure what all will interchange between the focus and cougar.

[ner_das_uc_k]

Most of them do its pretty crazy I always cross part numbers before I buy.

For porting the head this is how i understand it. Clean it up is the keep for a basic P&P. The exhauset side you could polish to a mirror for all anyone cars. The Intake should have basically be left to the grinding grit, but knock down the sharp edges and smooth it out so the surface flows constantly. I've seen guy dimple the intake ports to tumble the air, they claim it works.

For N/A Its Go big or go home is basically the option you have, of course this wouldn't stop anyone from doing a mild build of just port matching and be done with it.

For turbo, Enlarge, but be reasonable. You don't want areas to thin to create hot spots.

So If you actually serious, thats some knowlage.

P.S. Don't you dare use a dremel, air tool is the only way to go for this job.

or you could just take all the guess work out of it and buy a ford racing head for about $800. they still show up for sale from time to time and they are the biggest bang for your buck as far as heads go.

As far as polishing your intake ports goes, google why a golf ball has dimples all over it. The same principle applies to your intake ports.

The dimple idea is horsesh-t, you screw up flow patterns based on the dimple pattern itself. I've seen dimpling done but it has to be precise and much aforethought given to it. True dimpling is not a low hole, rather a low next to a high, made by dinging soft aluminum at 45 degree angle with a rounded small point punch. The HIGHS then become the flow modifying force.

What's the difference between golf balls and head surface, the ball spins rapidly, your head does not (or maybe ONE of them does, anyway). When head does not move the pattern will take on significance..........

Don't use dremel, you gotta be crazy. I use dremel, a set of 35000 rpm big tool and die grinders, drill, files, whatever it takes to get part of the job done. Airtools suck, the hose is always in the way. I use rocks, carbide cutters, cartridge rolls and flapper wheels to do it. And lots of WD40 to keep cutters clean.

The most rewarding work is always in the first one inch of valve pocket even if rest of head is untouched, these seem to be pretty clean as compared to earlier American engines and probably not so much to gain there as 1turbofocus has mentioned here before.

I have seen more novice ported heads of all brands than I can count yet the ones that I thought might work better than stock I could count on one hand. The bad ones were proven out at the strip to be dogs. If you have no idea of portflowing then the odds are highly in favor of the fact that you will be screwing your head up if you touch it.
