Teaser video of my car running again:

Mate was driving and was too nervous to drive it hard, so when I can drive again I'll get some better footage.

Can't watch the video brah

That's an impressive result, Stao. Really holds on up top now. Defo worth the effort of dual actuators IMO.

It made barely any difference Aaron, the dyno result was from two different AR rear housings if I read it right.

Stao, were they 20psi actuators?

We are talking about 1.2psi gain, not a mojor but there is a difference, notice the shape of the curve too. The 20psi actuator still had 3psi drop. this sheet was taken when using the same turbine housing

compare to:

The SS1PU probably had the most boost drop internally gated, this actuator setup should work well with that.

Do you bore out the wastegate hole Stao?

Maybe you could look at the EFR turbos and borrow some ideas from them to come up with a better rear housing design?

The SS1PU due to the higher pressure in the exhaust manifold, too much pressure here would cause heat issues though, you need an exhaust temp sensor in the manifold imo Stao.

Have you incorperated the longer actuator arm for more leverage also?

Ahh crap, I missed that the bottom graph was the two different rears.

Please refer to post 6125. They are identical turbochargers, both with .82 type B rear housings just different actuator setup.

Talk about great service!

I ordered my turbo on Monday, it was built and is already in the post. Stao has still been answering my queries and testing products in between, now that's what I call great service :)

Different arm to mine but looks to be similar length so should have same leverage

Stao mine has the longer arm and I lose 2psi up top. Is it worth loosening the screws and extending it out to the edge of have you tried that and made little difference?

Speaking of restrictions...both my cams look a couple degrees retarded. Might have to grab an adjustable gear for exhaust cam. Obviously need to put a dial gauge on and check for sure but if I see cheap cam gears in Japan next week ill be all over em

    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car

    • I believe @Duncan has given it a crack at Mt Buller before (in actual race conditions)
    • All my Polish car culture insight comes from watching Nightride. So I half expect this to get 1UZ swapped eventually?! Are you going to drive it in winter? I'm always curious how ATTESA would hold up in the snow. There isn't that much opportunity to try it in Australia.  
    • My steering lock unit on my Infiniti G37 has failed. The car is a local 2012 Infiniti G37 (Q60 ) I need to replace the unit My local mechanic said i need to buy a complete steering wheel assembly. Does anybody no any mechanics in Gold Coast or Brisbane who can fix this issue or where i can buy just the Steering lock control unit. Thanks
