Rb26 Turbo Upgrade, All Dyno Results

[hattori hanzo]

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.

 

Final Result with some more boost - 718rwhp @28psi (Dyno reads boost high)

 

 

Short nose RB26, stock bottom end. 

G35-1050 .86 rear vband

VCAM and 264 exhaust cam

Standard head, rebuilt , metal HG and ARP studs.

E85

Link G4X plugin
