good to see some results from the new G series turbos getting on the board.

 

Still getrag or gone sequential?

Yeah I’m quite surprised how well they go. Feels just as laggy as my old 84rs.

This was the final numbers with the g42-1200. Turbo has still got more left in it.

1011hp (753kw) @ 37psi e85
923hp (688kw) @ 35psi e85 (high boost)
753hp (561kw) @ 24psi e85 (low boost)
685hp (510kw) @ 20psi on BP98

Engine

Stock internals RB26

 Turbos

Garrett GT2860R-7s, 15.5 psi (currently boost is limited due to 7psi actuators)

Intake

Apexi power intake kit (twin pods)

Twin turbo pipe mod (plate welded into the TT pipe) to separate air to front and rear turbo to promote laminar flow and reduce turbulence

Stock intake pipework with AFMs inactive (O2 controlled by Link Wideband)

Exhaust

HPI stainless dump pipes

HPI stainless equal length front pipes

Apexi N1 3.5 inch stainless cat back

Stock cast exhaust manifolds, metal multilayer gasket, new genuine Nissan studs and nuts

Fuel System

1000cc Bosch Dynamic Flow Matched Injectors

Walbro 460lph Fuel Pump inc wiring upgrade direct to battery

Turbosmart FPR800 Fuel Pressure Regulator

 

Ignition System

Stock Ignitor

Splitfire Coil Packs

BCPR7ES plugs gapped to 0.7

ECU and Sensors

Link G4X ECU

CAN Wideband O2

Link Flex Fuel Sensor

Syltech fuel pressure sensor

Syltech oil temperature and pressure sensor

Syltech coolant temp sensor

Syltech air temp sensor

3 port MAC valve (electronic boost control via the ECU)

Tune

Dyno tuned for full flex

262kW on 98

282kW on E85

Was told by the tuner that I was limited by the small actuators (7psi) meaning they could only get 15.5psi with the boost controller, I have some HKS 14psi actuators incoming and will run it up again on 18-20psi.

Does VCAM work ... why yes, yes it does ....  On vs Off, only tuning the low end, boost on gate.

    • I'll snap up some photos when I'm back home, in the office today meeting my "in the office" quota. Have 2x Teams calls scheduled in, office culture they reckon.   I've never owned a proper off the shelf sub, I've always made or modified broken ones with Jaycar plate amps and/or car subwoofer drivers. The current (and broken) subwoofer has a proper home driver in it, Dayton driver, thos one https://www.daytonaudio.com/product/118/rss265hf-4-10-reference-hf-subwoofer-4-ohm FS of 25Hz, which is low but not low enough. Yeah, I think they were brought out to the market to compete with SVS. I would love a SVS PB-3000 but they're not cheap, especially after their price hike. From reviews online, it does look like the Tonewinner D6000 would destroy and with good amount of money saved too.
    • yeah, that happens too.  I'm really enjoying 4WDing at the moment, seen a few beautiful spots and want to go explore more of this enormous country.  The 370Z got a clutch LSD in it and a track day, great fun.  Getting the back end sorted out really rejuvenated my enthusiasm for driving it hard, the viscous one is poo especially in such a short and wide chassis.  The VLSD unpredictability was more benign in a long and skinny Skyline.
    • With my pre/power I use a remote trigger cable(3.5mm jack each end). I turn tv on, it turns both on via ARC. Or, just the pre with the remote or its streaming software, turns on both. Not that difficult at all. Obviously,  you would also want to actually update/upgrade over other factors in your life(bills, family, other hobbies, etc)
    • Yeah, nightfall was very "meh". And I'm crap at pvp, so feels like everyone has cheats(it's just my lack of skill). Final shape has been pretty good. New raid and dungeon are pretty good. If you want to give it a go, probably wait until it's on sale. But, as usual, most of it feels very familiar. 
    • This morning was Kingswood's Microscopic Wars. It is the album's 10 year anniversary this year and we went to see them play the whole album as a special show a couple of months back. Was pretty spectacular.
