Head Porting
 

ok... im offering this service as a side project. IM not a mechanic im not a machinest. but i do a damn good job. basically its a stage 1 port and polish job
all ports are port matched, all ports are smoothed out, intake port is sanded to a finish, exhaust port is polished untill its smooth to the touch, and combustion chamber and valves are cleaned and polished. then the head is cleaned and painted and shipped the next day once completed. I am oferring this for the low down ghetto price of 100$ or willing to trade for performance parts.
you pay all shipping costs. I can work something out if you are interested email me trajic1@hotmail.com

Re:Head Porting
 

got any pics of how it looks when ur done? id love to see a before and after Brian

Re:Head Porting
 

Do you even take the valves out and clean the bowl area?

Re:Head Porting
 

sound like a shady P&P job to me

Re:Head Porting
 

do i even take the valves out and clean that area.... come on.. im not cletis the slacked jawed yokel here... everything gets cleaned and polished. from there up

Re:Head Porting
 

Like i said im not a pro... im a do it yourselfer... found out i could do this.. did it to my car... its hauled more ass... i was happy so i wanted to offer it to more people.... cause i know how much those damn machine shops charge...

Re:Head Porting
 

You clean up the bowls but dont do a valve grind? Do you atleast lap the valves? If you are doing ANY kind of work near the bowls and slightly nick the valve seat its pretty much worthless and wont seal correctly. we do "Shady P&P's" but a valve grind is always neccasry afterwards.

Yeah what he said!

Re:Head Porting
 

Yeah i go through it very carefully.... pretty much just removing the carbon thats been caked on their... I dont use stone abrasives in that area.. because they tend to remove too much base material... as you mentioned 1 little ---- up and its bye bye valve seat, but i do remove the valve and give them a thourough clean up... nothing drastic... but still i would recomend a 3 angle valve job to everyone after i do this as to gaurantee its affectiveness

Re:Head Porting
 

fine.... 80$ its gonna be christmas soon... i feel generous.... ps.... i will be doing one sometime next week... i will take pics of the proccess... if i can get this gay ass web cam to work....

Re:Head Porting
 

right, having worked as a mechanic AND a machineist (was actually trained in all aspects of engineering.. welding and fab, sheet metal work, electrical, machining etc) in the past i would never trust some "mmm shiny" gimp to touch anything of mine,

RUNNING A FLAP WHEEL DOWN THE PORTS AND PAINTING IT DOESNT GIVE POWER

brain cell >:(


do it right first time, machine shops charge because they have massive overheads and have to pay the wages of skilled and experienced workers



on another note.

inlet ports should be slightly rough, and NEVER polished as the uber smooth surface causes fuel droplets to cling to the port walls and drop out of suspension, whereas a slightly rough finish gives turbulance which both keeps a "buffer" of air between the mixture and the port walls and enables the mixture to mix better in the port runners

Re:Head Porting
 

"mmm shiny" gimp...???? that better not be me your talking about.... dude you act like you think i dont know what the ---- is up..... I wouldnt be doing this ---- if i didnt know what i was doing.... I told you i wasnt a pro or anything.... just a god damn do it yourselfer.... now if you dont like that for any reason whatsoever... well all i can tell you is have a coke and a smile and shut the ---- up...

Re:Head Porting
 

He is right about the intake ports... On my intake ports I used a 50 grit whipitie. to give it some good turbulence. I polished the ---- out of my exhaust ports though.. It was like a damn mirror.

I am by no means a professional cylinder head porter. I just did the same thing as Punk_E_booster did.. just clean up the ports etc etc. Their is a huge science in head porting, especially on NA cars. but since most of us are working with FI cars, any type of cylinder porting cannot really hurt performance.

Re:Head Porting
 

That dude just pissed me off... sorry if I went on a rant... But he acts like i dont know what im doing... I mean I bought a Standard Abrasives Porting Kit and the video becuase i wanted this ---- done to my car. and I was quoted 350$ at this one machine shop. I baught the parts and the video for less than 100. I watched the video.. and did it just the way it said.. came out good... hasnt given me ---- since... I mean I did this just to gain a few extra horses... but this guy probably thinks were fixn em run em in NASCAR or NIRA or something... ----... if people are interested fine... If not well take it to a machine shop and spend more money.... im not gonna lie to you.... they will probably do a way better job than I can (im man enough to admit that) but theyre gonna charge you an arm and a leg... But thats if your dead fuckn seriouse about performance... if your looking for a cheap horsepower gain... well than hit me up.

Re:Head Porting
 

sorry if i sounded bitchy, but ive seen so many terrible "diy" jobs that i felt i needed to emphasise my point

Re:Head Porting
 

It's understandable... there are many people who do half assed jobs... just to make a profit and dont give a ---- what people say about their work as long as they get paid... I do this as a hobby... its something I like doing... working on things... taking something thats broken and fixing it.. or taking something thats normal and making it better.... its what i love to do... If i had the time and the resources i would probably do it for free... but i dont so I cant... but I think that 80$ is a resonable price. People spend around 200 bucks on headers, when their engine can only pump out so much exhaust???

Re:Head Porting
 

theres nothing wrong with what you are doing, its just a thorough de-coke of the head, i just think its a bit misleading to call it a port job...

now if i were to offer this service (which i wont, ive had enough of working on cars for other people bar my friends.. in which case i work for free) i would take the head into work, skim it recut the valve seats and lap in the valves.. probably waist the valve stems a little and smooth the back of the valve face.
then tidy up the ports (btw, knife edgeing the join of the intake ports is a BAD idea, as a slight radius is actually better for air flow) fit new collets and vsos, balance the ports up using a burette (good way to lower CR if low comp pistons are out of your price range) then paint it and give it back...

to go any further into head mods you really have to know engine specs, intended use etc etc... (which is why off-the-shelf ported heads are gay)

Re:Head Porting
 

oh well... only like 2 people emailed me.... but no one was really serious.... so i just say ----. it.. i aint doing this ---- no more...

Re:Head Porting
 

hi
im from the UK and am in the process of taking the cylinder head out of my engine to port and polish also. Do you have any tips? or are there any websites with step by step guides. I am like yourself a keen DIY'er just need a push in the right direction then no doubt second time round will be easier
thanks
Nick

This is the site that got me interested in porting my own head. I bought the video and the tools from them. It was a good investment

Re:Head Porting
 

tbh i'd say dont do anything apart from taking it apart, take it to a machine shop to have them check it for cracks,warpage and vavle guide wear.. if it gets the ok then feel free to tidy up the ports with emery cloth (amateurs+die grinders=hole in water jacket!), lap in the valves and put it back on

Re:Head Porting
 

i took a few head porting classes last year, and i am a machinist student. I got about 10 hp out of my d16a6 by porting it. gaining flow from the single cam is really easy. i have some really nice valve job equiptment too if anyone is interested i can make a deal with ya.
