Skyline R32 GTR — Stage 2 ECU Tune
- 55% power increase to 205kW
- 37% torque increase to 333Nm
- Improved boost control management
- Enhanced fuel delivery precision
- Optimized drive-by-wire integration
- Increased boost pressure at 20psi
This 1990 R32 GTR came in running the factory RB26 setup and left making 205 kW at the wheels on E85, up from 132 kW. The calibration was built around a Haltech platform with supporting fuel system work: high-pressure pump, injectors, and proper boost control through upgraded solenoids and wastegate management.
Peak torque sits at 333 Nm, with boost holding 1.38 bar. The file prioritises usable delivery for closed-circuit use, where the cooling and knock resistance of E85 let us lean into timing and fuelling without chasing peak numbers at the expense of reliability.
Stage 2 keeps the factory block and head intact while extracting what the fuel and platform allow. It's a sensible step for weekend track work without tearing into internals.
Why E85 over 98 RON for this build?
E85 offers better knock resistance and cooling, which allows more aggressive timing and boost on the RB26 without requiring race fuel. It's widely available and suits the power target without stressing the factory bottom end.
What's involved in the fuel system upgrade for this setup?
A high-pressure fuel pump and larger injectors were fitted to support the flow demands of E85 at 1.38 bar. Boost solenoids and wastegate control keep delivery stable across the range.
Is 205 kW safe on the standard RB26 block?
At this output, the factory internals are holding fine with proper calibration and fuel quality. It's a conservative Stage 2 target suited to regular circuit use without the cost of forged internals.
