Crx Type R B18: Achieving a 9-Second Quarter Mile
The Honda CRX Type R, with its lightweight chassis and rev-happy B16A engine, is a legend in the import car scene. But pushing it to a blistering 9-second quarter-mile time requires a significant upgrade, often involving a swap to a more powerful engine, like the B18C. Let's explore what it takes to achieve this impressive feat.
This isn't about bolt-on modifications; a 9-second quarter-mile in a CRX demands a comprehensive build, focusing on power, weight reduction, and optimized traction. This level of performance is achieved through serious commitment and significant investment.
What Engine Swaps Are Commonly Used for a 9-Second CRX?
The B18C is a popular choice for its relatively readily available power potential. However, even the B18C requires extensive modifications to reach 9-second quarter-mile territory. Many enthusiasts opt for higher-displacement or forced induction setups within the B-series family, or even consider alternative engine swaps, depending on budget and desired level of modification. The key is to substantially increase horsepower and torque beyond what a stock B16A or even a mildly modified B18C can deliver.
How Much Horsepower Is Needed for a 9-Second Quarter Mile in a CRX?
There's no magic number, as factors like weight, traction, and gearing significantly impact the final ET. However, expect to need well over 500 wheel horsepower (WHP). Reaching this level of power usually requires forced induction (turbocharging or supercharging) and extensive engine modifications, including forged internals, high-flow heads, upgraded fuel system, and a meticulously tuned ECU.
What Modifications Beyond the Engine Are Crucial for a 9-Second CRX?
Achieving a 9-second quarter-mile isn't solely about horsepower. Other crucial modifications include:
-
Weight Reduction: Stripping the interior, using lightweight body panels (fiberglass, carbon fiber), and removing unnecessary components are essential to improve the power-to-weight ratio. Every pound saved contributes to a faster time.
-
Drivetrain Upgrades: The stock drivetrain won't withstand the stresses of this level of power. Upgrades like a stronger transmission, axles, and limited-slip differential (LSD) are mandatory.
-
Suspension and Tires: A properly setup suspension ensures optimal traction, crucial for launching effectively and maintaining control during acceleration. High-performance, drag-radial tires are a must for maximum grip.
-
Safety Equipment: Given the extreme power levels, comprehensive safety equipment, including a roll cage, racing harnesses, and a fire suppression system, is absolutely paramount. Safety should always be the top priority in high-performance builds.
What Are the Costs Involved in Building a 9-Second CRX?
Building a CRX capable of a 9-second quarter-mile is an expensive undertaking. The costs can easily exceed $20,000, potentially much more depending on the extent of modifications and the quality of parts used. This includes the engine swap itself, fabrication work, tuning, and safety equipment.
Is It Possible to Achieve a 9-Second Quarter Mile with a Naturally Aspirated B-Series Engine?
While incredibly challenging, it’s theoretically possible with an extremely highly modified, large displacement, naturally aspirated B-series engine. However, it would require an exceptionally well-built engine with very high compression, along with extensive porting, and would necessitate pushing the limits of the engine's design. Forced induction (turbocharging or supercharging) is significantly more practical and efficient for this level of performance.
Building a 9-second CRX is a significant undertaking requiring expertise, specialized tools, and substantial financial resources. It’s a testament to the dedication and passion of car enthusiasts who strive for extreme performance. Remember, safety should always be the top priority in such projects.
