The Honda CRX Type R, a lightweight and nimble hatchback, is a popular choice for enthusiasts looking to build a powerful and fast track car. Achieving a 9-second quarter-mile time in a CRX Type R with a B18 engine requires a significant investment in modifications and a meticulous approach to tuning. This isn't a casual weekend project; it's a serious undertaking for experienced car builders. Let's delve into the specifics.
What Makes a 9-Second CRX Type R Possible?
A 9-second quarter-mile time translates to an incredibly fast car. To achieve this in a CRX Type R with a B18, you need to maximize power output while minimizing weight. This necessitates extensive modifications across multiple systems.
Engine Modifications: The Heart of the Beast
The B18 engine, while a strong foundation, needs substantial upgrades to produce the necessary horsepower for a 9-second pass. This typically involves:
- Forced Induction: Turbocharging or supercharging is essential. High-boost setups are necessary to reach the required power levels. Expect significant modifications to the engine internals to handle the increased stress.
- Internal Upgrades: Forged internals (pistons, connecting rods, crankshaft) are crucial to withstand the immense pressure of high boost. A high-performance head gasket is also a must.
- Fuel System: A high-flow fuel pump, larger injectors, and a boosted fuel management system (e.g., standalone ECU) are needed to deliver the fuel required for high horsepower.
- Exhaust System: A free-flowing exhaust system, including a high-flow header and exhaust manifold, is necessary to maximize engine breathing.
Drivetrain and Suspension: Handling the Power
Simply making horsepower isn't enough; the car needs to handle it effectively:
- Transmission: A reinforced transmission is necessary to handle the increased torque. A closer-ratio transmission might also be beneficial for improved acceleration.
- Differential: A limited-slip differential (LSD) is crucial for optimal traction and power transfer to the wheels.
- Suspension: A fully adjustable coilover suspension is needed to dial in the car's handling for optimal launch and acceleration. Lightweight wheels and sticky tires are also essential.
Weight Reduction: Every Pound Counts
Reducing weight is crucial for maximizing acceleration. This can involve:
- Lightweight Components: Replacing heavy components with lighter alternatives (e.g., carbon fiber body panels, lightweight seats, aluminum wheels) makes a significant difference.
- Stripping Interior: Removing unnecessary interior components further reduces weight.
Frequently Asked Questions (FAQ)
Here we address common questions surrounding a 9-second CRX Type R B18 build:
What kind of horsepower is needed for a 9-second quarter mile in a CRX Type R?
Achieving a 9-second quarter-mile typically requires at least 600-700 horsepower at the wheels, depending on the vehicle's weight, traction, and other factors. This is a significant increase from the stock B18's power output.
What is the cost of building a 9-second CRX Type R?
The cost can range from $20,000 to well over $50,000, depending on the parts used, the level of customization, and the labor involved. This is a substantial investment.
What are the potential risks of building such a powerful CRX Type R?
Building a car capable of a 9-second quarter-mile involves significant risks, including engine failure, transmission failure, and accidents due to the high speeds and power involved. Professional assistance and meticulous attention to detail are crucial.
What safety measures are essential for a 9-second CRX Type R?
Safety is paramount. A roll cage is crucial, as are racing harnesses, a fire suppression system, and a professional driver with track experience.
Is it street legal to drive a 9-second CRX Type R?
The legality of driving a highly modified CRX Type R on public roads varies significantly by location. Most likely, it wouldn't meet emissions standards and safety regulations. Track use is recommended.
Building a 9-second CRX Type R B18 is a challenging and expensive undertaking, requiring significant mechanical knowledge, skill, and resources. It's not a project for beginners. This level of performance necessitates a deep understanding of engine tuning, drivetrain dynamics, and safety considerations. Remember, safety should always be the top priority.
