1996 - 2000 Honda Civic engines were similar to the previous generation with some minor changes. All these engines had oil dip stick on Oil pump instead of in the center of the manifold just like on older 88-95 models of Honda Civic & Honda CRX. In Japan these engines come from EK grade Honda Civics. This is the 6th gen. Honda Civic engine. In USA engines were different for EX, HX & LX/DX. Honda Civic engine for LX & DX grades were non vtec Sohc motors & HX & EX were sohc vtec motors, that received D16Y8 engine. The non vtec motors were called D16Y7. HX motor vas D16Y5 VTEC-E motors. The SI grade Honda Civic motors were performance grade DOHC VTEC engines with B16A2 motors which are very famous around the world.
Although in Japan these motors were 1.5 ltr as well as 1.6 ltr. Japanese D15B Vtec & Non vtec engines fit American D16Y7 & D16Y8 motors also. The only difference is that some of these engines from Japan have 17 mm crank bolt and some have 19mm crank bolt, whereas US motors had 17 mm crank bolt.
6th gen Honda Civic was also very famous in Latin America and there is a shortage of these Civic Motors in such countries. The best & the most feasible option for these Honda Civic motors is the ones from Japan because Japanese people don't drive more than 5 years and average mileage on these is about 40,000-50,000 miles.
