Has anyone ported the AU i6 heads?

[trick_xd]

Yer I remember doing your bro's cyl head. that was at least 12 mths ago.
as you know I could have went more with your head but then you get into more machining costs and some times its worth it if your chasing out right power and your going to keep the car a long time to get the benefit from the cost involved ... some times its not if your going to get rid of the car in 1 or 2 years .... Your head was the good middle part.... not over the top but good value for money in power.

you should go into business trick_XD. Sounds like you have some great referrals and you know what your talking about. I may talk to you about giving the AU head of mine a clean up in future. ;)

My old man has a AU spare head he bought as a full recon, he had it on the car for about 1000km and took it off when his bottom end died for some unknown reason. I might buy it. Its nearly new. It might be a option to send you that head for some treatment when the time comes rather than rip the head off mine.

As a Hobby you can afford to do it cheaper then everyone else , all these shops in business need to make money and doing cyl heads will not get you a lot of money, it takes a lot of time and is a dirty job.
I am lucky that I have all the machines to do the job . and when I don't have my kids on the weekends then I don't mind doing cyl heads.


Hibbz ... PM sent

Thats fair mate. In fact I retract my previous statement. lol. It would be better for us members to pay you cash on the side if its as cut throat as you say.

[trick_xd]

LoL
Not a lot of people have access to just about everything they need .
and I am just lucky that I have .

Is head work the way to go ...... I think yes .... Is it expensive ... I think not really .. with the amount of other mods you would need to do just to match would exceed the 1K mark.
If I had my old hard drive I could post up pics of lots of different cylinder heads and different stages in work just so you can see how much work goes into just 1 head..

I use to do cyl heads for speedway cars and I have even done a motorbike head before .

What people really need to do before they just say "I want head work " is work out really want they want to do ... stay N/A or go Boosted .... mild ..... wild ...... petrol .... gas .... Everything you have ether now OR want to do later down the track will decide on what gets done to the cylinder head .. Next after that is price ..... Doing up a cylinder head is not cheap , at a shop you have to pay for there 50$ ph thats why a good cyl head compleat will set you back over 1K

I don't think I have ever herd of 1 person saying that there car was worse after getting head word done .

I have heard of a few people who have gone backwards from headwork.As me and Soxx have mentioned elsewhere.It is a tediuos ,dirty and time consuming job.For the work its not expensive but for a proper head rework /port you have to charge accordingly.

[blueoval]

yeah thats fair enough. you also pay for what u get too.

doing research also helps when choosing someone to do your work.

I'd love to see your work trick_xd.

[trick_xd]

There is pics on here some where of some of my work .

Joe will have a few as he wanted pics of his head

There is before and after pics of ports with a set of verniers measuring the port sizes

[stiddy]

I think there are huge huge gains to be had with head cam and tune, its just hard to find someone that knows what they are doing with the I6 head, many people claim they do, but often you will find a drop in power.
Dont get me wrong, there are people out there that really know what they are doing, it just comes down to $$$$.

[jonbays]

I'll back Stiddy on this. I had the head done but didn't get any noticeable or measurable gain at all. I made the mistake of getting it done whilst i didn't need the car on a business trip O/S. You need to carefully pick the guy to do the work and supervise it. A std reco head with an extra shave for more compression won't do zip. Asking for throating and detail work to be done with pictures etc didnt work for me because I didn't supervise the job. You need knowledge and patience both things you must pay for or you will waste your dough like I did.

the Kostecki heads are wonderful if you can afford to pay that much otherwise be careful. Anyone can do it its not hard to do just hard to get right. I used to do rotary engine bridgeporting to a pattern after I bought some bloody expensive housings from the US but you need to find someone who understands heads, flow and cams and can match them. Lot's of people will tell you they know how to do mit few can and those that can will charge and good on them.

[JoesAu]

i have lost all the detailed pics you gave me, im sure i have a couple on my old comp, will check tonight and post up whatever i have.

Kostecki is for sure they way to go and definately the way I will be heading when its time. Jonbays, you'd be the only person that I know of that aggrees with me about kostecki. Best heads on the market, garenteed gains and an over all powerhouse of a 6cylinder. Ive seen one of his head,cam and tuned motors produce 212rwkw with my own eyes.
Having been a rotor head, building 2 of my own (13b turbo ext mild port and 13b J-port) and helping many others, I know where your coming from. Its easy to work a head, anyone can do it. Its just hard, very hard to do it right.

[JoesAu]

does this kostecki supply cams?

[stiddy]

They do, but at $1100. More lift than a big block lol.

[Stav]

Ive seen kosteci claims but I am yet to see their results whatsoever.In giving benefit of the doubt..Stiddy where did you see this dyno run and has it been backed up with a timeslip maybe?

lol righto, i have the pics uploading

[JoesAu]

Ok after a headache from my old comp heres what i could find not much but trick xd might shed some light on the work?

[stiddy]

Stav, the car is an EF Falcon, Pro Automotive put the car together, Kostecki head, kostecki cam, complete fuel system, full ehxaust and intake, aftermarket engine managment with custom tune, other odds and ends. Standard box and diff, complete street trim on pump fuel pulled 212rwkw and also ran a 13.4 and 13.6 at WSID. Cant remember mph from memory but it was up around 105 I think.

For a car that weighs 1550kgs on ghia form I can see he has a 180kg advantage over the wagon and around 100kgs on a au or xr sedan. Sounds a bit arrogant to me.Maybe well just have to beat him with 141 rwkws

[trick_xd]

But Stav
its the way you get that 141kw to the ground that counts

How did someone getting there head ported end up in them loosing power.
What was done , what sort of head was it , what mods done to the motor?

[stiddy]

There was one of the guys on here, showed less power but more torque, and resulted in a slower ET over the 1/4.
There has been 2 I remember reading about on here that have lost power and run slower over the 1/4. Ive also helped a guy on here bolt on his new ported polished and worked head his car sounded totally different but no real noticeable improvements.

[Stav]

Car was an i6 au . Went in and got headwork from a proffessional workshop with a different cam and pulled 129 rwkws once completed. The same car pulled 144 rwkws on the same dyno before headwork.

The owner then got a dev 5 cam into it himself and gained around 11 rwkws back to around 141 rwkws in auto form.Original cam was a dev 3hl.

So for the bigger cam you would think that the headwork should have shown some improvement. I am mates with the owner and I was just as dissapointed as he was.I felt for the bloke...:(

I wont say who it was so it stays dead n buried that way and it doesn't bite me on the butt.
Stiddy ...sometimes a tune to tie in that guys mods may have woken up the power gains..but who knows?

[JoesAu]

the headwork made a noticable difference to my car, lot better torque, it revs heaps harder and the note of the car is mad. Key factors that i believe are holding me back are my extractors and the factory cam will go alot better when there sorted.

Its strange how hes power went down, sounds like they just hacked at the head and didnt know what they were doing

[stiddy]

Stav I know who your talking about thats why I havnt mentioned any names either.

Like I said before, anyone can work a head, but finding someone that knows what they are doing is the challenge.
