History of the Honda Integra Type R

The Honda Integra Type R, produced from 1995 to 2001 (with some variations depending on the market), was designed as the pinnacle of Honda’s performance-oriented vehicles. The car quickly gained recognition for its nimble handling, lightweight chassis, and, of course, its impressive engine performance. The DC2 (Japan) and DB8 (US) models are most often associated with the Integra Type R, both of which were equipped with Honda’s B18C and B18C5 engines.

The B18C was a series of 1.8L four-cylinder engines that became widely known for their high-revving nature, producing power outputs that far exceeded expectations for naturally aspirated engines. The B18C5, which was an enhanced version of the B18C, was used exclusively in the Integra Type R. This engine is lauded for its refinement, precision, and engineering excellence.

B18C Engine Overview

The B18C engine was part of Honda’s B-series family of engines, known for their versatile design and durability. It was used in several Honda models, but the highest-performing version found its way into the Integra Type R.

Key Specifications of the B18C Engine

• Displacement: 1.8 liters
• Cylinder Configuration: Inline-4
• Bore x Stroke: 81.0 mm x 89.0 mm
• Compression Ratio: 10.0:1
• Power Output: Around 170 hp (127 kW) at 7,800 rpm
• Torque: 130 lb-ft (176 Nm) at 6,200 rpm
• Valvetrain: DOHC (Double Overhead Cam), 16 valves
• Fuel System: Multi-point fuel injection
• Induction: Naturally aspirated

The B18C engine offered excellent throttle response and a smooth, high-revving experience. Its power delivery made the Integra Type R feel incredibly agile, especially when paired with a lightweight chassis and excellent suspension tuning.

B18C5 Engine Overview

The B18C5 engine is an upgraded version of the B18C, and it was the engine used in the Japanese-market DC2 and the U.S.-market DB8 Integra Type R. The B18C5 is widely regarded as one of Honda’s finest naturally aspirated engines and is a major reason why the Integra Type R remains a beloved car among performance enthusiasts.

Key Specifications of the B18C5 Engine

• Displacement: 1.8 liters
• Cylinder Configuration: Inline-4
• Bore x Stroke: 81.0 mm x 89.0 mm
• Compression Ratio: 10.8:1
• Power Output: 195 hp (145 kW) at 8,200 rpm
• Torque: 130 lb-ft (176 Nm) at 7,000 rpm
• Valvetrain: DOHC, 16 valves with VTEC (Variable Valve Timing and Lift Electronic Control)
• Fuel System: Multi-point fuel injection
• Induction: Naturally aspirated

The B18C5 engine came with a higher compression ratio and better components compared to the standard B18C, resulting in an increase in horsepower. The integration of VTEC allowed for variable camshaft timing, further improving both high-rpm power and low-end torque. It was specifically designed for track enthusiasts, offering the perfect balance between power, reliability, and efficiency.

Performance and Driving Experience

Both the B18C and B18C5 engines provided exhilarating driving experiences, but the B18C5, as seen in the Integra Type R, was the more focused performance engine. The higher redline (8,400 rpm) and greater horsepower output meant that the Integra Type R could accelerate quickly and hold its own on the track.

The light weight of the vehicle, coupled with the responsive engine, made for a dynamic driving experience. Whether on a twisty road or at the race track, the Integra Type R with the B18C5 engine handled with precision and offered a driving feel that was highly praised by automotive journalists.

Engine Components and Modifications

Both B18C and B18C5 engines are known for their durability and tunability. Many performance enthusiasts have chosen to modify and upgrade these engines, often looking for ways to increase horsepower or further optimize engine performance.

Common modifications include:

• Cold Air Intakes for better airflow
• Upgraded camshafts for enhanced performance at higher revs
• Performance exhaust systems for better exhaust flow
• ECU tuning or engine management systems to fine-tune the engine’s output
• Forged pistons and rods for high-performance builds
• Turbocharging or supercharging for boosted applications (though this would move the engine out of its original design)

Because these engines are highly regarded in the aftermarket community, parts and upgrades are relatively abundant, making the B18C and B18C5 engines an excellent choice for those looking to build a track-ready or street-performance vehicle.

Frequently Asked Questions (FAQ)

Q1: What is the difference between the B18C and B18C5 engines?

The B18C5 is an upgraded version of the B18C. The main differences are the higher compression ratio (10.8:1 compared to 10.0:1), the increased horsepower (195 hp for the B18C5 vs. 170 hp for the B18C), and the addition of VTEC technology in the B18C5. The B18C5 is designed for higher performance and is found in the Integra Type R.

Q2: Can I swap a B18C engine into a non-Type R Integra?

Yes, the B18C can be swapped into non-Type R Integras with proper modifications. However, the B18C5 (Type R version) is a more specialized engine that may require additional tuning and adjustments for the best performance.

Q3: How much power can I expect from a modified B18C or B18C5 engine?

With the right modifications, a B18C or B18C5 engine can easily exceed 200 horsepower. Many aftermarket parts like upgraded camshafts, intakes, and exhausts can push the engine well beyond its stock power output. Turbocharging or supercharging can push it to even higher levels, with some builds reaching upwards of 300-400 horsepower.

Q4: Is the B18C or B18C5 reliable?

Yes, both engines are well-regarded for their reliability, especially when properly maintained. The B18C5, in particular, was designed to withstand high-rpm driving and track use, making it a durable and dependable engine. Regular maintenance, such as oil changes and timing belt replacements, is crucial for longevity.

Q5: How does the B18C5 compare to other Honda performance engines like the K20?

The B18C5 is considered one of the best naturally aspirated engines Honda has ever produced. However, the K20 series (such as the K20A) offers more advanced features like better fuel economy, improved emissions, and more overall power potential. That said, the B18C5 remains a favorite among enthusiasts for its simplicity and high-revving nature.
