P n P job vs. re-sleeving
ok ....so maybe i labeled the last post wrong......and got a lot of gay feedback....lets try it again. I have an 01 EX and want to do some motor work to it. If anyone responding to this wont talk sh*t back and actually give me advice besides talking to someone else, i just wanna know if sleeving or a pnp job would create more power for my car and how i would go about re-sleeving, like if its possible and a site where i could purchase different sleeves.....if thats the better option power wise

Rep Power: 0 Why did you title this post "Port and Polish" if all you're asking about is boring cylinders and new sleeves? Those are two different things. Anyways, I would suggest PMing Catalyst with these questions, but only after you get the terminology correct. He seems to know a good amount of stuff about internal work.

Rep Power: 424 Wow... I'm just gonna say this. Leave your engine alone.
If you don't know what processes are called, then don't touch it. Your cousin may be a certified mechanic, but it takes quite a bit more than being a corner mechanic to be able to rip apart an engine, redesign the specs and successfully get it to run again. I suggest you get some books, read up, and consult with a couple engine builders before you start messing with anything.

Rep Power: 0 You're a wanna be who thinks generic ebay intakes outperform the well known quality namebrands. You're talking all sorts of **** and you dont even have pics of your ride posted. You supposedly live in a rich neighborhood, wheres your digital camera, dork?

Rep Power: 424 P&P is a step that you do with A LOT of other things in order to get power. You port and polish the runners along with getting a valve job, bigger valves, a higher lift/longer duration cam, new IM, bigger TB, all so that the head flows more air.
Sleeves aren't a power upgrade, they're a re-inforcement upgrade if the engine needs to be strengthened because it is making power or being subjected to heat and stresses beyond what it is intended to handle. That takes quite a bit, and just minor upgrades aren't going to get to that point.
But like I and everyone else said. If you don't know what you're doing, don't mess with it. You'll do far more damage than good trying to build an engine yourself. Its best left up to people who know what they're doing and get paid to do it on a daily basis. Engine building requires a lot of expensive special tools and a very clean controlled environment for it to come out right... Especially with an engine that has as tight tolerances as these do... its not like building a small block Chevy... everything is a lot tighter... what fits at one temperature may not fit at a few degrees on either side of it, and you don't want to find out the hard way.

Rep Power: 0 Adding onto what Boilermaker said, a home PnP job can do more damage than good. It's part art and part engineering. Just hogging out material doesn't necessarily increase flow. It take flow bench and experience to do it well. It's also easy to trash a head by holing a water jacket.
As for the sleeves, you ought to have a plan for the whole package. Just slapping in sleeves does nothing. It's an insurance policy for higher engine output.
