The following specifications summarize the B16A2 engine that powered the car.

• Engine code: B16A2


• Displacement: 1.6 L (approximately 1595–1597 cc)

• Torque: ~111 lb-ft at around 6,000–7,000 rpm


• Redline: roughly 8,000 rpm


• Transmission: 5-speed manual (standard on the Si)

These characteristics gave the Civic Si a high-revving, engaging character typical of B-series engines and contributed to its reputation for sporty handling.

Family and context

The B16A2 is part of Honda's B-series family, a lineup of performance-oriented, naturally aspirated four-cylinders used in various Civic, Integra, and Prelude models during the 1990s and early 2000s. In the Civic Si, the B16A2 served as a bridge between the earlier D-series powerplants and the later K-series lineup, offering significantly higher peak power with a lightweight, compact design.

VTEC technology in the B16A2

The B16A2 employs Honda's VTEC system to optimize valve timing for high-rev performance while maintaining usable low-end torque. This arrangement contributed to the Si's characteristic willingness to rev toward its redline.

Why it matters for enthusiasts

For many enthusiasts, the 2000 Civic Si's 1.6-liter VTEC engine is remembered for its expressive sound, rapid throttle response, and the way it encouraged a spirited driving style without sacrificing everyday practicality. It also helped anchor a generation of modding culture around B-series powerplants.

Summary

The 2000 Honda Civic Si used the B16A2 1.6-liter DOHC VTEC inline-four, delivering roughly 160 hp and 111 lb-ft of torque, paired with a 5-speed manual. This engine made the Si a standout in its year, known for its rev-happy nature and sporty character within a compact, affordable package.

Is the D16Z6 a VTEC engine?

SOHC 4-Cylinder VTEC
The 1.6-liter SOHC 4-cylinder engine in the Civic Si and EX (D16Z6) use VTEC to alter the timing and lift of just the intake valves. The exhaust valves use a fixed profile.

Does the K20Z3 have VTEC?

I find the K24Z7 a good balance between the peaky, high-revving engines and the torque-y turbo engines. It offers good low to mid-range torque while still offering a rev-happy driving experience with great induction noise. To answer the question, yes. 8th gen (K20Z3) is DOHC and has VTEC on both cams.

Does Civic Si have K24?

Now I am super excited to be driving this Civic SI because because it has had a K24 swapped into it normally these cars come with the K20. Which is a 2 L inline 4 and it makes about 200 horsepower.
