Port and Polish

[sodakevo]

I have a completely stock 03 Evo VIII. The question I have is about getting it ported and polished. I am good friends with a guy who has a race engine shop and he says he can give me a p&p for cheap (since we're friends). The only question is what will i have to do in terms of pistons and that stuff. I will be honest, I have no idea what i would have to do if i get it bored out. The other question i have about my new Evo is about Cams. Everyone says they do a lot for performance but i was just wondering about what it actually gives for power? Also if it downs gas mileage? Thanks guys.

If someone is talking about a port and polish, it usually involves the head; cleaning up the air passages on the intake and exhaust sides and the bowl area. It will flow more air more easily. If that indeed what he's talking about then it has nothing to do with the pistons or boring the block. Since you have a completely stock Evo, then maybe try some easier upgades first; exhaust, fuel upgades, boost control, and tuning. Try the bolt on stuff and see if you like the increased power before you go removing the head.
Cams are usually done after the mentioned bolt on stuff and they all make power by flowing more air though the motor.
More air + more fuel = more power, but less fuel milage. We can't have it both ways.

I hope you don't mind, but I moved your thread to the General forum. It will be seen a little more and you'll get more answers to your questions.

Well I just got my fully ported and polished head in last week and now it's on my car at Carz Performance and it is performing great. The more you can get it ported the better. The more air flow and gas= more HP. but like the other guy said get the other stuff done first cause taking the head off is alot of $$$$. So you mine as well get cams and head studs and you can do it all at once.

Keep in mind, bigger isn't always better when it comes to porting.
