A heavily modified Daihatsu reaching roughly 100 horsepower may not sound extraordinary on paper, but the build makes its modest target feel meaningful by showing how many small mechanical decisions are required to get there safely. The finale combines cosmetic cleanup, fuel-system work, ECU upgrades, road tuning and dyno testing before returning the finished car to the driveway where the creators say their earliest projects began. That mixture of practical modification and personal history gives the project more weight than a simple power-number chase.
The final preparation work is strongest when it stays focused on the car. Upgrading to larger injectors, installing the newer Haltech Nexus T1 and transferring the existing map provide a useful look at how programmable engine management can simplify later modifications. The explanation of sequential injection, injector compatibility and changing flow-rate settings is accessible without becoming excessively technical, while the immediate startup after the ECU swap makes the upgrade feel tangible rather than theoretical.
Some of the lighter material is considerably less convincing. The avocado-and-urine headlight restoration routine is played largely for comedy, and although explanations involving abrasion, oils and chemical compounds are offered, the segment ultimately acknowledges that a proper restoration kit would likely produce a better result. That self-correction helps, but the amount of time spent on the gag exceeds its practical value and temporarily distracts from the much more informative mechanical work surrounding it.
The road-tuning section effectively communicates why a project should be checked under ordinary driving before being pushed harder on a dyno. Coolant temperature, oil pressure and air-fuel ratio are monitored while ignition timing is adjusted, and the discussion makes clear that the goal is to identify obvious problems before paying for dyno time. The harsh coilovers, small tires, backfires and smoke also prevent the completed car from being presented as unrealistically perfect. Even the moment when the crew suspects something may be burning emphasizes that an inexpensive modified car can still have rough edges.
Dyno testing provides the technical centerpiece. Rather than immediately chasing a headline number, the tuner works through steady-state calibration, conservative boost, fueling, intake temperatures and engine protection settings before increasing output. Discovering that the wastegate plumbing appears to be reversed is particularly useful because it shows the kind of simple installation mistake that can undermine otherwise sound hardware. The discussion of torque delivery is also unusually worthwhile: the presenters explicitly note that a larger peak dyno figure does not automatically make a car better or faster on the street.
Reaching 75 kilowatts, presented as 100.8 horsepower, supplies a satisfying payoff without turning the result into something grander than it is. More importantly, the car appears to achieve that figure with a smooth-looking power curve and a deliberate emphasis on drivability and mechanical caution. The closing return to the original driveway then shifts the focus from performance to philosophy, framing the inexpensive Daihatsu as a reminder that modifying cars is less about prestige than improving whatever is available. The sentiment runs long in places, but because the location and model are directly connected to the creators' history, the farewell feels earned rather than artificially imposed.
Pros
- ECU, injector and tuning work is explained clearly enough to be informative without overwhelming casual viewers.
- Road testing realistically highlights heat, fueling, suspension harshness, smoke and other imperfections instead of treating the build as flawless.
- Dyno tuning emphasizes engine protection, drivability and diagnostic work rather than focusing exclusively on maximum power.
- The reversed wastegate plumbing provides a useful example of troubleshooting an apparently minor but important setup problem.
- Returning the finished Daihatsu to the original driveway gives the finale genuine thematic closure.
Cons
- The avocado-and-urine headlight segment spends too much time on a joke that the presenters themselves ultimately concede is inferior to a proper restoration kit.
- Promotional material for insurance, tuning hardware and the commemorative poster occasionally interrupts the project's momentum.
- The extended farewell repeats several similar reflections about the driveway, the channel's origins and the significance of inexpensive cars.
- The road portion is entertaining but sometimes drifts into unrelated personal stories when additional mechanical observation would have been more useful.
What makes the finale work is not the modest 100-horsepower milestone by itself, but the careful process of turning an overlooked little hatchback into something genuinely enjoyable and mechanically considered. The technical sections provide useful tuning insight, while the return to the original driveway gives the project an unusually personal sense of completion despite a few overlong comedic and sentimental detours.
