Fluid Checks and Changes: The Lifeblood of Your Si
Fluids are the lifeblood of any vehicle. For your 00 Honda Civic Si, staying on top of fluid changes is critical, especially given the high-revving nature of the B16A2 engine.
- Engine Oil: Change your engine oil and filter every 3,000-5,000 miles using a high-quality synthetic or semi-synthetic 5W-30 oil. Check the oil level weekly using the dipstick.
- Transmission Fluid: The manual transmission benefits from fresh Honda MTF (Manual Transmission Fluid) every 30,000 miles. Don’t use standard gear oil; it’s not designed for Honda transmissions.
- Coolant: Flush and replace your coolant every 2-3 years or 30,000 miles with a Honda-specific coolant. This prevents corrosion and ensures proper engine cooling.
- Brake Fluid: Bleed and replace your brake fluid every 2 years. Old brake fluid can absorb moisture, leading to a spongy pedal and reduced braking performance.
- Power Steering Fluid: Check the level and condition. If it looks dark or smells burnt, consider a flush and refill with Honda PSF.
Always use the correct fluid types specified by Honda. This is one of the best practices for 00 Honda Civic Si ownership.
Brake System Inspection: Stopping Power is Critical
Your Si is quick, but it also needs to stop quickly. Regularly inspect your brake system. This includes:
- Brake Pads: Check pad thickness. Replace them when they get low (typically around 3mm).
- Rotors: Look for excessive wear, deep grooves, or warping. Replace or resurface as needed.
- Brake Lines: Inspect for cracks, leaks, or corrosion. Any damage here is a safety hazard.
- Calipers: Ensure they move freely and aren’t seized. A seized caliper can cause uneven pad wear and pulling.
If you notice a soft pedal, grinding noises, or pulling to one side, address it immediately. Your safety depends on it.
Suspension and Steering Components: Keeping It Tight
The Si’s handling is legendary, but worn suspension components can ruin the experience. Periodically inspect:
- Bushings: Check control arm bushings, trailing arm bushings, and sway bar bushings for cracks or excessive play. Polyurethane replacements can offer improved feel and longevity.

- Tie Rod Ends: Check inner and outer tie rod ends for play.
- Shocks/Struts: Look for leaks or excessive bounce. Worn shocks will compromise handling and ride comfort.
Addressing these small issues early will maintain the crisp handling the Si is known for.
Common Problems and Troubleshooting for the 00 Honda Civic Si
Even a reliable car like the 00 Honda Civic Si has its quirks and common issues. Knowing what to look for can help you diagnose problems quickly and avoid costly repairs. Here are some common problems with 00 Honda Civic Si models.
VTEC Solenoid and Oil Pressure Switch Issues
The VTEC system is what gives the B16A2 its distinctive character. If VTEC isn’t engaging, or you get a check engine light for VTEC, it’s often due to a few common culprits:
- Low Oil Level: VTEC relies on oil pressure. Always ensure your oil level is full.
- Clogged VTEC Solenoid Screen: Over time, the small screen inside the VTEC solenoid can get clogged with oil sludge. Clean it carefully.
- Faulty VTEC Solenoid or Oil Pressure Switch: These components can fail. Testing them with a multimeter can help pinpoint the issue.
Always start with the simplest solution: check your oil and clean the screen before replacing parts.
Rust: The Silent Killer
Like many Hondas of its era, the 00 Civic Si is susceptible to rust, especially in regions with harsh winters or coastal environments. Common areas to check include:
- Rear Quarter Panels: Especially around the wheel arches.
- Rocker Panels: The sills along the bottom of the doors.
- Fender Lips: Where road spray collects.
- Subframe and Suspension Mounting Points: Critical structural areas.
Address surface rust early with sanding and rust-converting primer to prevent it from spreading. Serious structural rust requires professional intervention.
Third Gear Grind and Transmission Synchros
A common complaint among B-series transmission owners is a “third gear grind” or difficulty shifting into third, especially at high RPMs. This is usually due to worn third-gear synchros.
While you can replace the synchros, which is a labor-intensive job, sometimes a fresh fill of Honda MTF can alleviate minor issues. Avoid aggressive shifts, especially when the transmission is cold, to prolong synchro life. If the grind is severe, plan for a transmission rebuild or replacement.
Ignition System Woes: Spark Plugs, Wires, and Distributor
Misfires, rough idling, or a general lack of power can often be traced back to the ignition system. For the B16A2, common culprits include:
- Spark Plugs: Replace them every 30,000-60,000 miles with OEM-spec plugs (NGK is generally preferred).
- Spark Plug Wires: Check for cracking or degradation. Old wires can lose conductivity.
- Distributor Cap and Rotor: These wear out over time, leading to poor spark delivery. Inspect for carbon tracking or excessive wear.
- Ignition Coil: Located inside the distributor, the coil can fail, causing intermittent or complete misfires.
Diagnose misfires by checking individual cylinder spark and fuel delivery. A simple tune-up often resolves these issues.
Performance Upgrades and Modding Your 00 Honda Civic Si
The 00 Honda Civic Si is a fantastic platform for modifications. Whether you’re aiming for more power, better handling, or a unique look, there’s a vast aftermarket. However, always prioritize safety and reliability. Here’s how to 00 Honda Civic Si performance upgrades wisely.
Engine Performance: Breathing and Tuning
The B16A2 responds well to “bolt-on” modifications. Start with improving its breathing:
- Intake System: A cold air intake (CAI) or short ram intake (SRI) can improve throttle response and add a few horsepower. Brands like AEM, Injen, and Skunk2 are popular.
- Exhaust System: A quality header, high-flow catalytic converter, and cat-back exhaust system can free up significant power and give your Si a sportier sound. Look for systems from Skunk2, GReddy, or MagnaFlow.
- Engine Management: For more aggressive modifications, a tunable ECU (like Hondata S300 or KPro) and a professional tune are essential to optimize fuel and ignition maps for your specific setup. This is crucial for maximizing gains safely.
Remember, forced induction (turbocharging or supercharging) is a significant undertaking that requires internal engine modifications to be reliable. Always consult with experienced tuners.
Suspension and Handling: Sharpening the Blade
The Si’s double-wishbone suspension is already excellent, but you can make it even better:
- Coilovers or Spring/Shock Combo: Upgrading to adjustable coilovers (e.g., Tein, BC Racing) or a matched spring and shock kit (e.g., Koni Yellows with Eibach springs) will significantly improve handling and allow for ride height adjustment.
- Sway Bars: Larger front and rear sway bars (e.g., from Eibach or Skunk2) reduce body roll and sharpen turn-in.
- Bushings: Replacing old rubber bushings with polyurethane alternatives (Energy Suspension, Hardrace) can eliminate slop and provide a more direct feel.
- Strut Tower Braces: Front and rear strut tower braces can stiffen the chassis slightly, improving steering response.
A proper alignment after any suspension work is non-negotiable to prevent premature tire wear and ensure predictable handling.
Braking System Upgrades: Essential for Performance
If you’re adding power or driving aggressively, upgrading your brakes is a must:
- Performance Pads: Start with higher-performance brake pads (e.g., Hawk HPS, EBC Yellowstuff) and quality rotors.
- Stainless Steel Brake Lines: These reduce hose expansion under pressure, giving a firmer, more consistent pedal feel.
- Big Brake Kits (BBK): For serious track use, a big brake kit from brands like Wilwood or StopTech offers significant improvements in stopping power and fade resistance, but they are a substantial investment.
Always use fresh, high-quality DOT4 brake fluid with any brake upgrade.
