The Honda CRX VTEC 1.6 i-VT

In September 1989, Honda added the 1.6-litre 16-valve DOHC VTEC 4-cylinder B16A engine to the lineup outside of North America. The VTEC (variable valve timing and lift electronic control) engine provided increased power at high RPMs while still allowing low fuel consumption and better idling at low RPMs. The B16A produced 150 PS (110 kW; 148 hp) in the European 1.6i-VT model (where the engine bore the designation B16A1) and 160 PS (118 kW; 158 hp) in the JDM SiR model. The CR-X was the second car to receive a DOHC VTEC engine, shortly after the Honda Integra XSi.

The CR-X equipped with the 1.6-litre DOHC 4-cylinder engine or the 1.6-litre DOHC VTEC 4-cylinder engine came with a different bonnet since the twin-cam engines were taller and required additional bonnet clearances in comparison to the SOHC engines. The 1.6-litre DOHC engine was only slightly taller than the 1.6-litre SOHC engine and required a different bonnet with a bump on one side which offered the additional necessary clearance to clear the cam gear cover. Cars equipped with a 1.6-litre DOHC VTEC 4-cylinder engine came with a bonnet that was raised across most of the engine bay to offer additional overall clearance for the taller engine.

In some LHD European markets, there was also the option of the D14A1 engine with automatic gearbox which featured twin carbs and no PGMFI.
