Hybrid Racing Clutch Master Cylinder for 00-09 Honda S2000

Nissin S2000 Clutch Master Cylinder - OE Upgrade for 92-00 Civic & 94-01 Integra

This is the OE clutch master cylinder from the 2000-2009 Honda S2000, built by Nissin. OEM Honda clutch master and slave cylinders have proven to be the most reliable parts you can run in a hydraulic clutch system, and after years of testing and swapping through the alternatives, Nissin is the only brand we trust for this job. On an S2000 it's a straight OE replacement. On a 92-00 Civic or 94-01 Integra it's one of the most popular clutch upgrades you can do, and for a good reason.

Why the S2000 Master Cylinder Is the One to Run

What sets this master cylinder apart is the integrated reservoir. Instead of a remote-mounted fluid reservoir feeding the cylinder through a separate line, the reservoir bolts directly to the aluminum housing. That matters more than it sounds. The factory setup on the EG/EK/DC2 cars uses a remotely mounted reservoir, and over the years that reservoir and the line connecting it fade, crack, and eventually leak. When that line lets go you get brake-and-clutch fluid, which is corrosive, spilling in the engine bay, and a car that won't move because the clutch has no pressure. The S2000 cylinder removes that failure point entirely. You clean up the engine bay, drop a known weak spot, and get a firmer, better-feeling clutch pedal in the process.

Direct Fit on the S2000

If you're installing this in a 2000-2009 Honda S2000, there's nothing to figure out. It's a direct OE replacement part, no modifications, no extra hardware. Bolt it in, bleed the system, and you're done.

Fitting It to the EG, EK, and DC2

On the 92-00 Civic and 94-01 Integra this is a "semi-universal" part. It fits those cars and works well, but it isn't a no-thought bolt-in, and knowing that up front keeps you from getting stuck halfway through the job.

Two things are involved. First, you need a different clutch line. The S2000 master cylinder uses a different fitting than the factory EG/EK/DC2 line, so the stock line will not connect. This is required, not a maybe. Second, in most cases you'll need a spacer. Mounting the S2000 cylinder on these chassis leaves a mismatch in the push-rod and clevis length, and running it without correcting that will give you a bad pedal and poor engagement. Our Hybrid Racing S2000 Clutch Master Cylinder Spacer corrects that rod and clevis length, and it comes with a foam seal that keeps water and debris from working their way into the cabin through the firewall. It's been tested in race cars for months and is the piece we built specifically to make this swap right.

Before You Order

Make sure you have the correct application before you install. On an S2000 it's plug-and-play. On anything else, plan on an aftermarket clutch line and, in most cases, the spacer. We're not responsible for incorrect fitment caused by using it on the wrong application, so line up the supporting parts before the cylinder goes on the car.
