The Honda S2000 AP2 is already near-perfect from the factory, but these five carefully chosen modifications transform it into a surgical canyon weapon. While most S2000 builds chase power numbers, this $12,000 setup focuses on what the F22C engine and chassis were born to do — carve mountain roads with precision that embarrasses cars costing twice as much.

Suspension That Actually Works

The AP2's double-wishbone suspension is brilliant, but Honda's compromise springs and dampers leave performance on the table. KW V3 coilovers with Hardrace rear lower control arms fix the geometry issues that plague aggressive driving. The KW V3s offer separate compression and rebound adjustment — critical for dialing in the S2000's tendency to lift the inside rear wheel.

Hardrace's rear LCAs address the AP2's rear toe change under load. Stock arms allow excessive toe-out during cornering, creating the loose rear-end feel that scares inexperienced drivers. The $3,500 suspension package transforms the car's balance without sacrificing daily comfort.

F22C Breathing Modifications

The F22C engine responds beautifully to breathing modifications, but the key is supporting the high-rev nature rather than fighting it. The ASM intake manifold flows 15% better than stock and moves peak power up 500rpm — exactly where you want it on a naturally aspirated Honda.

Toda Racing headers are the gold standard for S2000 builds. Equal-length runners and proper collector design maintain the F22C's linear power delivery while adding 15-20 wheel horsepower across the rev range. The KTuner V2 flash brings it all together by moving VTEC engagement from 6000rpm to 5800rpm — more area under the curve where you actually drive.

This $4,000 engine package delivers 240 wheel horsepower of naturally aspirated perfection. The power gain isn't dramatic, but the improved throttle response and mid-range torque make the car feel completely different.

Mugen MF10 Wheel Setup

The Mugen MF10 in 17x7 +42 front, 17x8 +45 rear is the wheel Honda should have used from the factory. This staggered setup maintains the AP2's natural balance while reducing unsprung weight compared to the stock 17x7 square setup. 215/45R17 front, 245/40R17 rear with Yokohama AD09 tires provides the grip needed to exploit the suspension improvements.

The MF10's forged construction saves 3-4 pounds per wheel compared to stock, and the slightly wider rear helps put power down without overwhelming the chassis. At $4,500 for wheels and tires, it's not cheap, but the transformation in feel is immediate. The car rotates more predictably and carries more speed through corners.

$12K Build Cost Breakdown

Here's the realistic cost breakdown for this AP2 canyon build:

• KW V3 coilovers: $2,200
• Hardrace rear LCAs: $1,300
• ASM intake manifold: $1,800
• Toda Racing header: $1,500
• KTuner V2 + tune: $700
• Mugen MF10 wheels: $3,200
• Yokohama AD09 tires: $1,300

Total investment: $12,000 for a transformation that makes the AP2 feel like a completely different car. This isn't about chasing dyno numbers — it's about creating a daily driver that transforms into a canyon weapon when the road gets twisty. For comparison with other naturally aspirated builds, check our Nissan 350Z VQ35DE canyon build guide covering similar philosophy with different execution.

Supporting modifications like the Mishimoto silicone hose kit at $200 help maintain reliability under increased stress. Don't forget quality brake pads like the PosiQuiet premium front brake pads for $55 to match the improved performance.

Canyon Performance Reality

This build creates a car that's comfortable for daily driving but transforms completely when you hit your favorite mountain road. The KW V3s provide civilized street manners with track-capable performance when you dial in the damping. The engine modifications add just enough power to complement the improved chassis without overwhelming the mechanical grip.

The beauty of this setup is the balance. You're not chasing 400+ horsepower like turbo builds — you're optimizing what Honda already got right. The result is a car that flows through corners with surgical precision, rewards smooth inputs, and teaches you to be a better driver. For drivers who understand that horsepower isn't everything, this AP2 build represents the perfect evolution of Honda's masterpiece.
