^^ Exactly.

Every shop will tell you how great they are & they know what needs to be done to the head.. but how many people or workshops have the runs on the board.

I believe RAMS cylinder heads in windsor have supplied many heads for CRD's big build engines.

But im not sure who paul from Red R racing uses for porting his cylinder heads ?..but its safe to say he has more than enough experience as to exactly whats

required as far as intended horsepower goals or times on the track..and he shares his knowledge which many others are reluctant to do.

head porting is done in house, and yes soon to have cnc porting as well. 1500hp engines need a well sorted head and paul does just that he gives you what you

want and some.

i would cut the middle man out and go straight to the head guy

10%+some profit is alot of money when your taking a 7k head

If the head guy is trying to run a respectable business he would not build/port a head and for an individual and undercut another person trying to run a business!

Assuming 10% gst +10% profit

so to ship a head to a head dude somewhere = $1400

i aint no rocket scientist but i recon i can box up a head ship it to a head dude with 20 + year experience for 50 bux

head dude still charges you the same, he still has the same results on paper

respectable business.... 80% people out there pay the head dude once cnc map their work then pump em out just tiding up the loose ends that the cnc cant reach..and claim the work as their own and charge 50 bux less

A lot of companies outsource work to others, if you're the machine shop, why would you not accept their work? You're just the machinist doing the machine work for a customer, if those customers turn around and say its their own work then good for them, that doesnt mean that going direct to the machinist is wrong.

99% are assemblers and get head work outsourced, you get the head done direct you save alot. Handfuls of big name engine builders all outsource to different head companies.

Head porting is a real art, don't go anywhere that can't show you proven results on a dyno.

The Guys down at Envy are doing a new head cutting method on all there heads. Its called DIGIPORTING. They are running a XR6T with one of their heads and it makes over 1100hp ATW along with a set of Platinum Race Cams and are only running it at 28psi of boost.They also have several other cars with great resaults with the same equipment.

Have a look at this earlier GTR they have done http://www.youtube.com/user/EnvyDyno#p/u/52/-THGNYiouWs

Have a look at the XR6T on this site as well its bull S##t.

Fill free to call Herman at Envy on: (02) 9907 4144 :(

If the machinist accepts the work based it is definitely wrong mate, think about it.

Anyway, what is DIGIPORTING???

Haha, ok, I'm "thinking about it" and as any one coming to a logical conclusion will come to, here's the conclusion;

Unless there's a contract in place for the machinist to not replicate a certain port job, he can do as many of those port jobs as he likes.

Its like I call up a local machine shop and get them to port a head. I can try and call it a steve ported head, but its not. It's someone elses work with a different label.

If one company though, goes and tests a heap of heads, then gets one digitised and agrees with the machine shop that only them are allowed to order that head, then the machinist sells that port job openly, that's of course very wrong.

It is only wrong if they are making a laser cad design of the head then replicating it without paying fees or at least asking that it is wrong. People resell others work all the time eg engine builders often don't disclose what parts they are using, they however didn't cast the pistons etc.

I agree 100% and that was the point I was trying to make :D

ah nice quest, i dont know the answer to that one but it has somthing to do with digitially matching the heads to the block and chambers. What ever it is it looks to work well.

^^^ What ??...

Sounds like magic beans..

A good explanation would be nice...looking at their website all i see is two guys attacking a cylinder head at the same time with die grinders. :whistling:

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.

      Skyline v36 350GT sedan hunting on idle

      By Robot · Posted

      Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣

      After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
