More power only counts when the engine, fuel system, tune, and drivetrain can repeat it. The roadmap separates what the car is today from what later hardware may support.
Stock F23A7 rods, K20A3 cast pistons, GT35, 91 octane, and approximately 5 PSI.
Forged I-beam rods, titanium retainers, upgraded valve springs, and careful tuning while still respecting the cast piston and 91-octane limits.
A serious future configuration with forged pistons, stronger fuel, known injectors, head sealing, and drivetrain upgrades.
The current engine is 10.37:1 estimated compression, turbocharged, on 91 octane, with stock rods and cast pistons. That makes verification and conservative tuning the priority.
Verify at idle and at RPM once oil is fully warm.
Confirm base and 1:1 rising-rate behavior under boost.
Sync actual crank timing to commanded eCtune timing.
Confirm calibration and sensor placement before relying on AFR data.
Prove the engine before using the 3-port controller aggressively.
AFR, MAP, RPM, coolant, IAT, battery voltage, and ignition timing.
Look for heat, timing, and fuel issues after early pulls.
Inspect every leak path, keep timing conservative on 91, and document each milestone.
For a full-interior FWD roll car, the next chapters should document boost-by-speed or boost-by-gear strategy, charge temperature, gearing, tire behavior, and repeatable high-speed acceleration—not just peak dyno power.
Any competition or high-speed testing should be conducted only at legal, controlled venues.
