splitter stays in the final product looks good and i cant see any problems with defects its alot better then having a turbo reaching for the sky and saying ill take a red one officer. on my set up i had no problems with boost control after my MBC was removed i was using a small gate to 35mm. the 44mm will have no problems controlling things. i think the external gate on the manifold will help the mani flow so much more then without. iv had 260kw though a 38 pipe a 44 could flow over 300+ im guessing

yeah i know il correct myself 200 depending on turbo. it comes down to personal preferance i like it on the manifold as i can put a diferent turbo on if i blow one with the housing your restricted to what turbo can be used. im going to be putting a gt3040 on one of these manifolds and there is no way im welding to one of those housings

External gate is VERY hard to keep hidden. Even custom jobs that I have seen where the intention was to hide the gate, it's still easily spotted if the cops are looking around. if you're worried about cops at all, I wouldn't be going external gate.

I'm not worried about them at all hanaldo I'm just trying to keep it away from first thing to be seen if you know what I mean

And keeping it easy for turbo change if need be for pits

That's it alot of the time if something catches there eye they will defect you most if the time they don't get there heads in the engine bay just look for something sticking out they are like crows shining things get there attention

I was trying for stealth too with my setup, thats why I avoided external gate for a while, but the boost control is awesome it sounds great.

I have heard both good and bad stories about welding on the manifold, but as of yet I have never heard any issues with welding on the housing of the turbo - provided it is in the correct spot for flow, there is a diagram somewhere about it.

I got mine heat sprayed aswell for stealth+ cooling ( for cooling it was a waste of time, cant remember all up but I think was about 400 for manifold and turbo housing and had to send it away for a week ) but I think the matt balck does help instead of a bright colour.

Decided to make a aluminium heatshield aswell to cover the external gate - which 1. worked way better for hiding things 2. actually functioned as a great heat barrier.

Maybe you could do something like that? Sure, a cop if they were keen could see something, but with the intake pipe ontop and other crap its very hard to tell and just looks like a heat shield... if they are that keen they will get you either way.....

This was while I was finishing drilling the holes for it:

Quoted from the Turbosmart installation manual:

- DO NOT wrap the body of the wastegate with exhaust wrap

- DO NOT Mount the wastegate so that the top diaphragm housing is less than 100mm from a heat source

- Allow for adequate cool airflow around the top diaphragm housing

In nsw the cops are lazy. My mate with a 33 god defected for the STD bov then he had to get a blueslip to pass so no matter what you do they will pick anything they can shiny or not. I got done for having a gear knob with no patten go figures. Thanks Simon32 yeah the cast seems to break in the perfect spot everytime then the cleaning part sucks. You could have the wastegate mounted under the turbo but boost spikes would be a issue

    • I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!
    • I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
    • The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.
    • No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
    • Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.
