Honda chose to incorporate VTEC into the 1.8-liter engine for the B18C, in contrast to the B18B, on which the manufacturer experimented without using VTEC. A new generation of engines with “motorcycle” characteristics emerged with the introduction of the B18C engine, which could spin at over 9000 rpm and produce more than 100 horsepower per liter of volume.
From 1993 until 2001, the company produced the 1.8-liter Honda B18C gasoline engine, which was installed on charged versions of well-known models like the Integra and Civic. There were numerous variations of the B18C motor, which can be classified as either Type R or conventional.
Internal combustion engines (B16A, B16B, B18B, and B20B) are also part of the B-series.
The engine was mounted on:
- Honda Civic 6 (EJ) in 1995 – 2000;
- Honda Integra 3 (DB) in 1993 – 2001.

Disadvantages of the Honda B18C engine
This unit is extremely dependable in both the forced and normal versions;
Only the water pump and thermostat may malfunction up to 100,000 kilometers in the engine;
If the timing belt breaks after 90,000 kilometers, the valve will bend.
Numerous instances of the cylinder head gasket breaking through at high mileage are described in the forums;
Because there are no hydraulic lifters, valves must be adjusted every 40,000 kilometers.
Honda B18C engine modifications
B18C Type-R, an analog of B18C5 with a compression ratio of 11.1, is a modified B18C. 200 horsepower at 8000 rpm and 186 Nm of torque at 7200 rpm. A 4-1 exhaust manifold was utilized in the B18C 98 Spec R. The Honda Integra Type R was equipped with this engine.
The North American Integra GS-R’sengineis the B18C1. The compression ratio is lowered to 10, making it comparable to the Japanese B18C. The intake manifold shifts at 5800 rpm, while the VTEC shifts at 4400 rpm. The Acura Integra GS-R engine produces 170 horsepower at 6300 rpm and 145 Nm of torque at 4800 rpm.
Australia and New Zealand’s equivalent of B18C1 is B18C2. B18C3, the Asian equivalent of B18C1, was installed on the Integra VTi-R. set up on Integra.
The European equivalent of B18C1 is B18C4. installed on the Prelude and Honda Civic.
For the American Integra Type R, B18C5 is a modified version of B18C1. This engine has new camshafts (effective phase 240/235, lift 11.5/10.5 mm), light connecting rods, new pistons with deeper counterbores for a compression ratio of 10.6, a shifted VTEC switching to 5700 rpm, ported intake and exhaust ports, and lightened intake valves with a slightly thinner stem and lighter head. Additionally, they installed additional candles, a new intake manifold, a more direct exhaust system on a 57 mm pipe, double valve springs, and a throttle valve that was increased to 62 mm (on the B18C1, it was 60 mm). Consequently, torque is now 176 at 7500 rpm and power has increased to 195 horsepower at 8000 rpm. 8400 rpm was the new cutoff.
The B18C Type R, which was installed on the Honda Integra Type R, has a European equivalent called B18C6.
The Australian version of the B18C Type R, which was fitted to the Honda Integra Type R, is called B18C7.
