Honda S2000 Parts

The Honda S2000 is a legendary Japanese sports car. It is defined by its incredible chassis and the high-revving F20C and F22C engines. Achieving a specific output of over 120 horsepower per liter, this naturally-aspirated (NA) engine is a masterpiece of Japanese engineering.

But for race enthusiasts who track their car or simply push it to the 8,200 RPM redline consistently, there are a few key Honda S2000 parts you will need to upgrade or maintain to ensure the engine remains reliable for years. These upgrades? They focus less on dramatic power increases and more on eliminating known stress points to guarantee that the engine's factory performance potential is maximized safely. Let's delve into the most crucial component you'll need for your Honda S2000 to achieve high-RPM performance and long-term engine health.

The AP2 Valve Spring Retainer Conversion

One of the most frequently discussed topics in the Honda S2000 community is the risk of valve spring retainer failure, especially on the early AP1 (F20C) models. Designed to be lightweight for an incredible 9,000 RPM redline, the original retainer's design can be prone to cracking under repeated high-stress operation. This can lead to a dropped valve and terrible engine failure.

Replacing the thinner AP1 retainers with the thicker, more durable AP2 valve spring retainers is a mandatory preventative measure for anyone planning heavy track use or sustained high-RPM driving. This simple valvetrain upgrade is a cheap insurance policy that gives the driver immense peace of mind.

Upgraded Timing Chain Tensioner (TCT)

One of the most common issues that can affect the long-term reliability of the F20C and F22C engines is the factory Timing Chain Tensioner (TCT). This part is responsible for maintaining the correct tightness of the timing chain, which synchronizes the entire engine. Under aggressive driving, the stock unit tends to wear out, leading to a noticeable rattling sound upon startup. In worst case scenarios, drivers may even experience catastrophic engine failure.

Replacing the original unit with a robust, high-quality aftermarket TCT is crucial and inexpensive, giving race enthusiasts peace of mind when exploring the upper reaches of the tachometer.

Cooling System Upgrades (Radiator and Vents)

During track days or spirited driving, sustained high-RPM use puts immense thermal pressure on the engine. This makes cooling critical for long-term reliability. Upgrading your Honda S2000's cooling system is a vital process that supports reliable power.

Replace the factory radiator with a larger, higher-capacity aluminum model, like those from Koyo or CSF, to significantly improve heat dissipation. Plus, installing functional S2000 hood vents will also help extract high-pressure, hot air from the engine bay, increasing airflow through the radiator and improving both cooling efficiency and front-end downforce.

FAQs

Is Honda bringing back the S2000?

It's not official and Honda hasn't confirmed it, but there are rumors suggesting a potential revival for the 2026 model year. Speculations say that it's going to be a modern roadster with a turbocharged engine and possibly hybrid-assisted, aiming to capture the high-performance spirit of the original Honda S2000.

Is Honda making a new S2000?

As of now, the next-generation S2000 remains highly anticipated but unannounced by Honda.

Is the Honda S2000 RWD?

Yes, the original Honda S2000 (both AP1 and AP2 chassis) features a classic front-mid engine, Rear-Wheel Drive (RWD) layout.

Do all AP1 S2000s need valve spring retainer upgrades?

Not all AP1 engines will fail, but the risk increases with frequent high-RPM or track driving. Upgrading to AP2 retainers is widely considered best practice for preventative maintenance.
