As a long-time Honda Accord Coupe owner and racing enthusiast, I’m always exploring ways to enhance my vehicle’s speed and handling. While the Accord Coupe offers a sporty drive right off the dealer lot, a few aftermarket modifications can transform it into a true high performance machine.
In this comprehensive guide, I’ll share all the methods I’ve used to make my V6 Accord Coupe faster, whether it’s reducing 0-60 times or achieving higher top speeds. We’ll cover beginner mods like intakes and exhausts up to advanced options like engine supercharging.

4 Easy Upgrades to Boost Accord Coupe Performance
Table of Content
Here are a few straightforward DIY mods to unlock some extra muscle from your stock Honda powerplant:
⚙️ Install Cold Air Intake
Replacing the factory airbox with an aftermarket cold air intake is a popular first mod on the Accord Coupe. Opening up the air intake path reduces restriction, allowing more oxygen into the engine for combustion. A larger mass air flow sensor calibration may be needed.
Benefit: 📈 5+ horsepower gain
💨 Add Cat-Back Exhaust
Reduce back pressure and improve airflow out of the engine with a full cat-back exhaust system (headers back). High-flow mufflers like Magnaflow open up the stock restrictive exhaust path significantly.
Benefit: ⚡️ 7-15 horsepower gain
⚡️ Upgrade Ignition System
Optimize the engine’s spark with premium spark plugs, performance ignition coils, and maybe a tuned PCM. I run NGK Iridium plugs with MSD Blaster coils for maximized combustion.
Benefit: 🔥 Improved ignition for better combustion
🛞 Adjust Clutch Engagement
If running a manual transmission, consider adjusting your clutch engagement point to launch harder from a standstill. Be careful not to prematurely wear the clutch facing material.
Benefit: 🚦 Quicker launch times
Those four upgrades alone can cut your 0-60 acceleration times by a few tenths and raise trap speeds – all from easy bolt-on parts! Now let’s look at more advanced mods.
Major Power Adders to Give Your Accord Coupe 200+ HP
Want to seriously boost output from your Accord Coupe’s factory 200 horsepower engine? Here are two options that will have you blowing the doors off unsuspecting challengers:
🚀 Add a Supercharger
Supercharging involves adding a belt-driven air compressor to force feed the engine up to 15 PSI of pressurized air. Kits are available to boost the J-series V6 up to 400 horsepower to the wheels! Proper supporting fuel mods are mandatory.
Benefit: 📈60-150+ horsepower gains
🌪 Install a Turbocharger
Turbocharger kits mount exhaust-driven air compressors to increase intake pressure, similar to superchargers. Expect big top-end horsepower gains from a properly tuned turbo Accord Coupe. A robust fuel and ignition system is key.
Benefit: 📈100-250+ horsepower potential
Forced induction mods like these enable your Accord Coupe to embarrass AMG drivers while still retaining the Honda’s reliability. They do get pricey though, often running $5,000+. Now let’s shift gears to handling upgrades.
Optimize Chassis and Suspension for Track Performance
Below I cover suspension and chassis modifications to transform your Accord into a grippy, stiffly sprung canyon carver:
↔️ Widen Track Width
Installing wider wheels/tires pushes the tire contact patches outboard, lowering center of gravity for vastly improved cornering. Wider fenders or pulls may be needed to prevent rubbing at full lock.
Benefit: 🚗 Flatter cornering
🪚 Lower Vehicle Height
Dropping ride height via quality aftermarket springs and dampers quickens steering response and reduces body roll through tight turns. Expect a firmer ride. Watch for rubbing issues over large bumps.
Benefit: ⚖️ Increased handling balance
➕ Add Sway Bars
Bolt-on thicker anti-roll bars keep the chassis flat through swift transitions by limiting body roll. Tuned properly, sway bars make the Coupe far more nimble without sacrificing too much ride quality.
Benefit: ♿ Increased high-speed stability
Plus further advanced mods like upgraded control arms, strut bars, chassis bracing, etc to maximize lateral grip when pushing the limits.
Final Thoughts
With the right combination of carefully selected mods above, your 9th gen Honda Accord Coupe can be utterly transformed from mild-mannered daily to track-storming turbo beast.
Just be smart and avoid overloading the drivetrain or chassis with too much power at once. And ALWAYS verify your car insurance coverage before modding – some companies may deny claims if unauthorized upgrades are made.
As you venture into modifying your Accord Coupe for higher performance, drop me a line with any tuning questions that come up! I’m always happy to share knowledge from my years of Honda/Acura racing experience. VTEC just kicked in yo! 😎💨
Frequently Asked Questions
How Much Horsepower Can I Add To My Stock Accord Coupe?
With straightforward bolt-on mods focused on the intake, exhaust, etc – expect ~15-30 HP gains. With advanced forced induction from turbos/superchargers, 200+ horsepower can be added to reach 400+ at the crank, depending on supporting mods and tuning.
What Is The Fastest Possible Accord Coupe?
Using the 278hp J35Y6 motor from the TLX Type S combined with a Well Engineered turbo kit, custom cams, and E85 fueling, 700+ WHP Accord Coupes have been created. Quarter miles in the 8s have been achieved!
Will Performance Mods Void My Honda Factory Warranty?
Unfortunately Honda can deny warranty claims if aftermarket parts caused the failure in question. Unless mods are installed by a dealer (ex. Hondata tune), assume your warranty coverage is compromised. Always good to buy an extended plan!
Is The V6 Or I4 Accord Coupe Better For Tuning?
The J-series V6 engines take very well to forced induction with their iron blocks and readily available upgrade parts. The turbo K-series I4 motors still offer great potential though. Ultimately depending on your budget and power goals!
