2.0L (G4NA)

[edit]

The Nu 2.0 L (1,999 cc) version of this engine features the same 81 mm (3.19 in) bore but with a longer stroke of 97 mm (3.8 in). First revision of the G4NA engine makes 166 PS (122 kW; 164 hp) at 6,500 rpm and 20.5 kg⋅m (148 lb⋅ft; 201 N⋅m) at 4,800 rpm while later revisions produce 152–156 PS (112–115 kW; 150–154 hp) at 6,200 rpm and 19.6–19.9 kg⋅m (142–144 lb⋅ft; 192–195 N⋅m) at 4,500 rpm.

Applications

2.0L CVVL (G4ND)

[edit]

Primary change is adding the CVVL, the engine produces 172 PS (127 kW; 170 hp) at 6,700 rpm and 20.5 kg⋅m (148 lb⋅ft; 201 N⋅m) at 4,800 rpm.

Applications
