Installation notes

Yes — the B16A2 engine and transmission from a 1999-2000 Civic Si (EM1) fits a 1992-1995 Civic (EG) with B-series engine mounts, B-series swap axles, a B-series shift linkage and an ECU/harness that matches the chassis. Hasport states its EGSTK mount kit works with the B16A2 and B16A3 (2-bolt left-hand bracket, hydraulic transmission) in the 92-95 Civic. The B16A2 is a 1.6 L DOHC VTEC rated at 160 hp in the US Civic Si. Axle and linkage parts are B-series specific because the transmission uses an intermediate shaft that the D-series EG did not have.

Required modifications

Engine mounts: the B16A2 uses a 2-bolt left-hand (timing side) block bracket and a hydraulic-clutch transmission; Hasport lists its EGSTK kit for B16A2/B16A3 engines with that bracket in the EG (cars with a 3-bolt bracket use DCSTK instead). Axles: B-series swap axles that work with the hydraulic B-series intermediate shaft (Hasport EGBAX is one listed option). Shifter: a B-series shift linkage (Hasport EGBLINK is listed for 92-00 Civic B-swaps). Wiring/ECU: the 1999-2000 Civic Si is an OBD2 car and the EG is OBD1, so the engine harness, ECU and sensor connectors have to be reconciled. Clutch: manual EG Civics already have a hydraulic clutch; an EG that was originally an automatic needs a clutch pedal assembly, master cylinder and line.

Caution

Important caveats

  • Check whether your B16A2 has the 2-bolt or 3-bolt left-hand block bracket before buying mounts; Hasport sells different kits for each.
  • The EM1 Civic Si is OBD2 and the EG is OBD1, so plan the ECU and wiring adapters before the swap.
  • Hasport lists its B-series axles for street use only and requires the hydraulic intermediate shaft.
  • The Hasport B-series shift linkage is not listed for the 1993-1997 Civic del Sol.
