Al, thanks for the info (only noticed your post today). I did read something a little while ago about someone doing the hiflow with VG30 exh housing and getting good results. I'll look into it as well - and yes, it's also added to my confusion :)

porschephile, definately post up the dyno chart from your friends car if you can - i'd be very interested to have a look. I assume that your friend has the GT2835 with the .87 turbine housing?

Also, just having another look at the Nengun website. They have the 2835's on special for $2,560 delivered to Sydney ;)

One question though, they have 2 versions of the GT2835 with A/R 0.87...one with Strong Actuator attached 80mm diameter and the other with 100mm diametre.

Pardon my ignorance, but what exactly does the actuator do and which choice would be better for my application?

The wastegate actuator controls the amount of boost that is pushed through the turbo by pushing excess exhaust gases through the wastegate. The harder the spring is the harder it will be to open the wastegate thus controlling boost.

Not sure which actuator is better, as i am note that technically minded, i usually ask the turbo experts that type of question and allow them to make the decision for me :).

About my combo and your decision, if you could hold off for about 3 weeks i should most definately have a dyno graph to post up. Head has already been sent to be ported, turbo sent to be upgraded, ecu out to be upgraded, cams have arrived, it's all moving quite nicely :D

      Cleaning my wheels 😍

      By Milkmun · Posted

      Can't say I've had a bad experience with one on my car, then again it only gets washed once or twice a year... The wheels on the other hand, get a good spray often due to my shitty dusty pads.

      @MBS206 thats pretty neat and tidy to me!  I'll get a photo of mine when I'm out there next. It might require multiple photos to understand the scale of the atrocities though... In total I have 4 sheds of varying sizes and layouts. Main shed is 14x8, second shed is 3x8, third shed is 11x2.5, fourth shed is around 6x4.  All are pretty much full.   The main goal of my cleaning tsunami is to make the main shed predominantly car and motorbikes only. Second shed is my metal fab room (2 x bench grinders, drill press, bench belt sander, metal band saw, scrap metal storage and some of my garden tools.  3rd shed is more bigger garden stuff, storage for engine crane, jack stands, concrete grinder, concrete mixer, air compressor lives there, and it now has two 2mx2m pallet racking shelves with itemised boxes holding building stuff, electrical stuff, plumbing stuff, etc, etc.  The 4th shed is Ryobi electric ride on mower, mini boom sprayer, ancient Kubota tractor, more garden stuff!  I have got a lot of shit....  Then there's the pool house (8mx4m) and the pool pump shed (4mx4m).  I built all of the sheds over the 11 years we've been here.  The main shed was a Ranbuild kit, the rest are all custom made to fit the areas available. Building the main shed taught me a LOT as I had no idea about building anything prior to that!  I've still got one more in me. It will be my man cave which I poured the extra concrete for way back when I poured the concrete for the main shed. The idea is the Skyline will be a centre piece of the main cave once (if...) it's finished.  I told my now 14 year old son yesterday that I will 100% drive him to his year 10 formal in 2 years. Still a long way off but at least I now have a date to work towards! 🤣

      Modern oils are amazing. Add tyres to that as well.

      Probably a smart choice to buy one vs build, purely for the motivation part as you said! Imagine the metal dust everywhere from grinding all the steel to build one. Ha ha ha!   Also, post a photo of your garage.   Mine is below, this is where I've been cleaning and have already half filled a caged 6*4 trailer. And this is after my cleaning expedition mentioned previously... The middle normally has a car in it, but I'm dumping things in the middle as I sort through them. And poor skyline was dusty and has had the lightest few drops of rain and now it looks atrocious and needs to be dragged back out and washed thoroughly! And yes to the right is technically another bay, you really can only see 2 bays out of 3 in this picture.

      It's more like on average the things I see a lot of things going wrong. Yes, usually the people who reach out are the ones who are having problems but on average it feels like mechanics and tuners here aren't really competent. I swing between thinking my standards are just way too high and wondering whether people really are just this dumb. I just had the strangest 10+ reply argument on a Facebook group over someone insisting that the factory R34 GTT boost control solenoid reduces boost pressure to 5 psi when it's on and raises boost pressure to 7 psi when it's off despite showing the exact plumbing in the factory service manual and the solenoid behavior detailed in the FSM.
