Engine port and polish

port and polish

what goes into it, how much does it cost, what are the pros, cons? anything

do a search

damn u cant tell me no1 here has done it

again.....

more than likely it will cost more than it is worth on a corolla

He has a DIY on it.<br />
Get a dremel tool.<br />

Do it yourself!

isnt there sumthing we can bore or mill or shave or wutever to get some cheap horses

depends on where you get it done. I can get my engine ported and polished for 600 from this guy I know. I know they make the intake and exhaust lobes bigger for optimal combustion. Also the exhaust ports to your headers are increased in size. They use a sysetem where they flow air to the heads and have a little ball floating or different electrical systems determine the percentages of airflow. I'm not sure also but they can have it to where they increase the piston ports so you can get bigger ones in for more displacement. I'm not totally sure if this but porting and polishing is a great way to increase raw horsepower from the engine. Just watch out with the prices from different places.

Depends if your going N/A or forced induction. If you have an F-series head - don't do it, not much to do in there other than some touch-up work on some welds and some leftover flash material. Most people make the intake too smooth - which takes out the &quot;tumble&quot; in the intake charge - actually you'll lose some power. For the price of a P&amp;P - you could have bought a NOS kit.

Wow.... 6 bills? That's not bad.

You might be thinking of shaving down an engine block, increasing compression, thus a few more HP.

i dont know if i trust myself with a dremel......

wut if they fuck up?

even if any of you guys DID get a P&amp;P no one would bother dynoing before/after lol

nething else we can mill, bore, shave or polish or somoething similar 2 gain horses

yeah, go on a diet.

you can take 700 grit sandpaper to your flywheel and sand it to remove weight!!!

It cost me 1200 to get my head ported and polished , new valves and seats

and did you dyno?

96 hp 97tq

sucks..

yes but it is ready for lots of boost right now I am running too lean . once I get that part fixedI should be at 105 area

thank god i have a 4ag with bolt ons that already exceeds that (109.6whp), and is running lean as well

if you've put that much money and have seen that little gain, someone is pulling your leg

lean GIVES you horsepower.... part of tuning is finding how lean you can run without detonation

you lose power through detonation, but other youre only going to lose power running to rich.... a piston engine runs like ass when to rich

actually in my power mechanics class they were talking about how going extra lean causes the engine to heat up more, making the engine less efficient, and losing power......

& i'm retarded..... the ae92 isn't running lean, it's running rich..... probably a bad o2 sensor.....

well then good thing i said "lean" and not "extra lean"
