The EK1/EK2/EK3/EK4/EK5/EK8/EK9/EJ6/EJ7/EJ8/EM1 Honda Civic is the 6th generation

All EK and EJ chassis Civics run a 4x100 bolt pattern with a 56.1mm hub bore. That's the same pattern Honda used on the prior EG and the following EP chassis, so wheel compatibility across 90s and early 2000s Civics is wide open.

Both are sixth-generation Civics (1996-2000). The EK codes cover hatches and some coupes, while EJ codes cover sedans and certain coupe trims. The EK9 is the JDM Civic Type R hatchback with the B16B. The EM1 is the USDM Si coupe with the B16A2. Mechanically they share the same platform, subframes, and suspension geometry. The distinction matters most when you're sourcing body panels or trim-specific parts.

The spread is wide. Base models got the D16Y7 (106 hp, single cam, no VTEC). The EX and HX trims ran D16Y8 and D16Y5 variants with VTEC. The EM1 Si came with the B16A2 (160 hp, dual cam VTEC). JDM EK9 Type R owners got the B16B (185 hp), which remains one of the highest specific-output naturally aspirated 1.6L engines Honda ever built. The D-series is bulletproof and boring. The B-series is where the fun starts.

For B-series, the EK is one of the easiest Hondas to swap. The EM1 already has B-series mounts, so dropping a B18C1 or B18C5 into any EK hatch or coupe is well-documented. Mounts, axles, shift linkage, and ECU harness kits exist from multiple aftermarket sources. K-series swaps are more involved. You need swap mounts, a custom or adapter harness, modified shifter setup, and usually a K-series compatible ECU. Both swaps are proven and thousands of builds deep at this point.
