The EJ20X and EJ20Y are open deck engines whereby the cylinder walls were supported at the three and nine o’clock positions. It came with an aluminium alloy block with 92 mm (3.62 in) bores – with cast iron cylinder liners – and a 75 mm (2.95 in) stroke for a capacity of 498.6 cc (30.43 cu in) per cylinder, with thicker cylinder walls than EJ25. The crankcase for the EJ20X and EJ20Y engines had five main bearings and the flywheel housing was cast with the crankcase for increased rigidity. The EJ20X engine is understood to have a forged crankshaft and connecting rods, but cast aluminium pistons with forged crowns. The EJ20X and EJ20Y engines had an aluminium alloy cylinder head with cross-flow cooling, double overhead camshafts (DOHC) per cylinder bank and four valves per cylinder that were actuated by roller rocker arms.
The EJ20X and EJ20Y engines were equipped with Subaru’s ‘Dual Active Valve Control System’ (‘Dual AVCS’) which provided variable intake and exhaust valve timing. The Legacy GT, the EJ20X engine was fitted with a twin-scroll IHI VF38 turbocharger; the EJ20Y engine, however, had a larger twin-scroll Mitsubishi TD04 HLA 19T turbocharger. For the revised BL.II Legacy GT, both the EJ20X and EJ20Y had an IHI VF44 turbocharger for the initial 2006 model year, replaced the following year with the IHI VF45.
Both came with a 9.5:1 compression and a fast spooling turbo yields a torque filled performance. 265–280 bhp (198–209 kW; 269–284 PS)
