The 2000 Civic Si Still Deserves Your Attention
A lot of people on forums get fixated on newer Hondas or the later RSX, but the 2000 Civic Si—specifically the EK9-generation model with the B18C5 RedTop—represents something most modern cars have lost. It was the last year Honda bundled that particular engine into a compact FWD platform before shifting to the K-series and the double-wishbone front suspension setup. The B18C5 made 170 horsepower at 7,600 rpm and 130 lb-ft of torque at 5,500 rpm, naturally aspirated, with VTEC kicking in around 5,100 rpm. That power band is narrow by modern standards, but it was deliberate. The engine revs cleanly to the redline, the VTEC transition is a distinct moment of surprise, and the power delivery is linear enough that you always know what the car is going to do. The five-speed manual had close ratios, and the limited-slip differential meant the front wheels actually found traction when you pushed hard out of a corner. I had one when I was twenty-two. Put about forty thousand miles on it over six years. The steering was direct—there was no numbness in the rack, no vague middle position. Turn the wheel and the car responded immediately. Weight distribution sat right around 60/40 front to rear, which is unusual for a front-wheel-drive car and explains a lot about why it rotated so willingly.
Why It Matters Technically
The engineering choices Honda made for that chassis were conservative but purposeful. Independent double-wishbone front suspension with coil springs,MacPherson strut rear with a torsion beam, and a solid anti-roll bar setup front and rear. The subframes were rigidly mounted. Brakes were ventilated discs up front and solid discs in back, with ABS only available on certain trims. What most people miss is how much the engine mounts mattered. The 2000 Si used different mount stiffness compared to the base Civic. Softer mounts reduceNVH for daily driving but allow a tiny bit of engine movement under hard acceleration. Stiffer aftermarket mounts fix that but transmit more vibration into the cabin. I ran OEM-spec rubber mounts for most of the car's life. They were worn by mile forty but the vechicle still felt tight.
Common Problems You Will Face
These cars are nearly thirty years old now. Here is what actually goes wrong: Rust is the first thing. Check the rocker panels, the wheel arches, and the floor pans. Surface rust on the subframe is normal for the age. Structural corrosion is not. Look for patches, welding marks, or any area where the metal feels soft when you press on it. Check for smooth shifting through all five gears. The synchros on these tend to wear on the first and second gears specifically. Grinding when downshifting into first usually means worn blocker rings. Third and fourth are generally fine unless the car has been neglected.
Get the Full Details
Listen for knocking from the bottom end when the engine is cold. A healthy B18C5 has some valve train noise from the hydraulic lash adjusters, but it should quiet down within thirty seconds of startup. Persistent ticking after warmup indicates worn lifters or valvetrain components. Verify the odometer. These cars were driven hard by a lot of people. A realistic reading for a well-maintained example is between eighty and one hundred thirty thousand miles. Under fifty thousand miles on a three-decade-old car is suspicious and usually means the number was rolled back.
Practical Upgrades That Actually Help
Most modifications for this car are incremental rather than transformative. The chassis is already competent. Adding stiffer sway bars reduces body roll without destroying ride quality. A short-shift kit changes nothing meaningful about performance but makes gear changes slightly quicker, which matters in track use. Tires are the single most impactful upgrade. A set of good summer performance tires like the Yokohama ADVAN Sport or Michelin Pilot Sport 4S will make the car feel ten years newer. The stock Dunlop or BFGoodrich tires from the factory are adequate but not inspiring. Brake pads and rotors deserve attention if they are original. The stock pads fade quickly under repeated hard use. Aftermarket metallic compound pads give better initial bite and resist fade better, at the cost of slightly more rotor wear. I prefer semi-metallic pads for track days and softer organic pads for street driving.
What It Cannot Do
This car is not fast by current standards. Zero to sixty sits around seven seconds with a stock exhaust and air filter. Quarter-mile time is roughly fifteen seconds. It will lose a meaningful race to almost any modern compact sedan on a drag strip. The interior materials degrade. Vinyl cracks, cloth seats wear through on the driver's side bolster, and the dash pads develop a permanent shine from sun exposure. Replacements exist but are becoming harder to find and more expensive than the cars themselves. Maintenance costs have risen because the parts supply chain is thinner. Honda still produces some OEM items, but third-party support has contracted compared to the early two-thousands. Expect to pay a premium for NOS (new old stock) components, especially for body panels and trim pieces.
If you want modern reliability and technology, buy a used Mazda3 or a Corolla. The Civic Si from two thousand is a mechanical experience, not a convenience appliance. It demands attention, it rewards drivers who understand how to use it, and it will frustrate you if you treat it like a grocery getter. Most people who buy one knowing what they are getting tend to keep it longer than intended.
