Everyday Usage of a D Series Turbo Kit
How a D Series Turbo Kit Elevates Your Honda
Adding a turbo kit to your D Series Honda engine—such as the D15, D16, or D18—supercharges your ride by forcing more air into the cylinders. This means more horsepower, crisper throttle response, and a driving experience that’s simply more exhilarating. For many, it’s a gateway to street performance, weekend track events, or simply enjoying spirited, reliable power in a daily driver.
Typical Application Scenarios
- Daily Driving: With the right professional setup, a mild turbo kit can deliver reliable, efficient extra power for day-to-day use.
- Weekend Racing: More aggressive kits provide boost for autocross, drag racing, or time attack events.
- Show Cars: Shiny, high-quality hardware (like billet compressor wheels, polished manifolds) adds style for car meets and shows.
- Project Builds: Turbo kits are a staple upgrade in performance projects or engine swaps for aging Civic, CRX, or Del Sol models.
Benefits of Upgrading to a D Series Turbo Kit
Installing a turbo kit unlocks a range of both performance and practical benefits:
- Significant Horsepower Gains: Depending on the kit, power increases of 100+ hp are possible on stock motors; built engines can exceed 400+ hp.
- Customizable Performance: Adjustable with boost controllers and wastegates—tailor your power to your needs.
- Retain OEM Features: Many turbo kits permit the continued use of air conditioning and power steering for comfort and convenience.
- Complete Solutions: Most kits include all major hardware (turbo, manifold, intercooler, piping, lines, wastegate, blow-off valve) for a comprehensive install.
- Better Cooling and Engine Protection: Inclusion of intercoolers, oil coolers, and (in some kits) turbo timers helps safeguard against heat-related engine wear.
- Cost-Effective Power: For D Series engines, turbocharging often represents the best value-per-horsepower upgrade compared to costly engine swaps or NA builds.
How to Choose the Right D Series Turbo Kit
Selecting the right kit requires understanding your goals, budget, and vehicle specifics. Use this checklist and advice to narrow your choices:
1. Define Your Performance Goals
- Street Only: A mild kit offering 6-8 PSI with a smaller turbo is ideal for daily drivers or cruisers.
- Track/Competition: Larger turbos and supporting mods (built engine internals, fueling, upgraded clutch) required for 300+ HP builds.
2. Check Compatibility
- Identify your exact engine code (D15B, D16Y8, D16Z6, etc.).
- Ensure kit is designed for your chassis and year. Some 88-91 chassis require modification for newer kits.
3. Kit Content
- Look for complete kits that include: turbocharger, manifold, downpipe, intercooler and piping, oil/coolant lines, wastegate, BOV, gaskets/hardware.
- For DIYers: “custom” or universal kits may need extra fabrication or welding.
- Some kits include advanced features: turbo timer, oil cooler, slim cooling fan, or catch can.
4. Turbocharger Specs
- T3T4 Hybrids (commonly in Rev9, Speedyracer, MMIspeedshop kits) balance quick spool with high horsepower ceiling.
- Ceramic Ball Bearing and Billet Wheels (Affordable Turbo Kits S3, high-end kits) offer faster spool, better efficiency, and longevity.
5. Warranty and Support
- Look for kits with included warranty—often requires professional installation.
- Consider the reputation of both kit and retailer for after-sales support.
6. Budgeting for Additional Parts
- Many kits do NOT include engine management, injectors, fuel pump, or upgraded clutch—budget for these essentials.
- Installation can vary from simple (bolt-on) to moderately complex (requires custom fitting or fabrication).
User Tips and Best Practices
1. Professional Installation Strongly Recommended
- Ensures reliability, proper tuning, and validates most warranties.
- Reduces common missteps (leaks, improper oil feeds, misaligned piping).
2. Boost Management
- Run low boost (5-8 PSI) on stock internals.
- Upgrade internals (forged pistons/rods) for safe 15+ PSI and over 300 HP.
3. Proper Tuning is Critical
- Invest in a quality standalone ECU, piggyback, or dyno tune.
- Untuned turbo builds risk engine damage.
4. Upgrade Supporting Systems
- Fuel: Larger injectors, performance fuel pump, adjustable FPR (Fuel Pressure Regulator) common additions.
- Cooling: High-quality intercooler and, for high HP builds, oil coolers and slim fans for thermal management.
- Drivetrain: Consider a performance clutch and, at higher power, better axles.
5. Maintenance and Monitoring
- Change oil more frequently—synthetic is best for turbo longevity.
- Monitor AFR (air-fuel ratio), EGT (exhaust gas temp), and boost pressures.
- Turbo timers help ensure proper cool-down for turbo longevity.
6. Legal and Insurance Considerations
- Many turbo kits are sold “for off-road or competition use only.” Check emissions and local laws.
- Notify your insurer about modifications to avoid issues with coverage.

Practical Tips and Advice
Best Practices for Turbocharging Your D Series Honda
- Start with Healthy Engine: Before turbocharging, ensure your D Series engine is in excellent health—good compression and oil pressure are prerequisites.
- Set Power Expectations: Stock engines typically hold ~220-250 HP at the wheels with proper tuning and conservative boost. For 350+ HP, plan a full engine build.
- Plan Fuel System Upgrades: Boost requires fuel! At minimum, install high-flow injectors and a compatible fuel pump.
- Cooling Counts: For sustained performance and engine longevity, use an efficient front-mount intercooler and, if possible, an oil cooler.
- Don’t Skip the Tune: Engine management is the most critical mod—budget for professional dyno tuning and a management system matched to your build.
- Expect Some Customization: Even “bolt-on” kits may require tweaks (exhaust rerouting, AC/PS line adjustments, fabrication).
- Stimulate Airflow: Upgrade your exhaust system after the turbo—restrictive OEM exhausts can limit gains.
- Monitor Everything: Gauges for boost, oil pressure, and air-fuel ratios catch potential problems early.
- Stay Legal and Safe: Respect local emissions laws—some kits aren’t legal for street use. Always install with safety in mind.
