I've been reading up about doing a port n polish on my baby. Good gains are expected and its not very costly. ANyone know if this is a myth? and how much should i expect to spend and where can this be done?

I wouldn't mind doing both. for starters, the intake manifold if all goes well then the head as well. I haven't got any benchmarks on recent upgrades yet AEM cai, Ti-c exhaust but i'm hopeing to see more with a pnp!

I turn to this because theres no race header for R18 :redface:

i'm not too keen on the disassembly of my engine so i'm curious if any race shops might do this and if theres much performance gain to be forced out of this engine. lol

Do more research, you DON'T want to do it yourself, and a good pnp job will cost you well over $1200, +engine disassembly.

Some people are really dumb and think "Oh I'll just do it myself and smooth out the rough edges", not realizing its much more involved than that, and you can really screw up the flow of your engine, as can a basic cheap port job.

Yeah Port and Polish head work is more for more built N/A or F/I engine. You wont benefit from this on a stock set up with just bolt ons. Port and polish is to help increase air flow. But if nothing more is there to help move the air then the work is useless. Port work usually comes with cams and some form to up compression in the cylinder. So unless you are doing cams at the same time PnP is not needed.At the same time no tuning is available to do this mod anyways yet. But PnP responds well in F/I since this needs flow. I would say save your money. the $1200 for the PnP plus the engine tear down is a total of a couple grand which would be a nice down payment for a F/I system which would net more power then the PnP job.

thats for a full head work

if you only want to improve the flow its not too expensive

you can check some prices here

also i agree.... this is not a DIY...
it requires years of experience and it NEED to be tested on a flow bech... at least...

Yeah, like a 3 angle job, which is considered entry level, 5 angle runs upwards of 2K. You would only want to do this if putting in new cams and doing something with your TB as well.

^^ true but still have to take the head off and send it to the shop. Not worth the money when the money can be spent else were for more results. PnP is mostly done after all other mods are done and a person want to improve what he has. The K20 head flows so well PnP isn't needed unless a guy is going full race.
