The 1999 Honda Civic EX uses a 1.6-liter inline-four with Honda’s VTEC system, commonly identified by the engine code D16Y8, producing about 127 horsepower.
In the United States’ sixth‑generation Civic lineup, the EX trim sits a notch above the base DX and LX, pairing the 1.6L VTEC powerplant with features that emphasized a sportier driving character and stronger performance for the era.

The following overview summarizes the core specifications and characteristics of the 1.6-liter engine powering the 1999 Civic EX.

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.
