An angle seat piston valve is a pneumatically-controlled valve with a piston actuator providing linear actuation to lift a seal off its seat. The seat is set at an angle to provide the maximum possible flow when unseated. Angle seat piston valves are particularly suited to applications where high temperatures and large flow rates are required ...
This newer '20V' engine, along with the SR20VET, were the only SR20 engines to get restyled valve covers. It also came with an upgraded intake manifold, which has longer runners and a larger 70 mm (2.8 in) throttle body (earlier SR20VE has 60 mm).

Mazda's MZI version [citation needed] adds variable valve timing, as does Jaguar's AJ30. Note that the MZI name is also used in Europe on Mazda's version of the Ford Sigma I4 . The 3.0 L (2,967 cc), 220.71 hp (165 kW) V6 used in the Mondeo ST220 is called Duratec ST . 3.0 L (2,967 cc) 204 hp (152 kW) V6 in the Mondeo Titanium is called Duratec ...
The Nissan L series of automobile engines was produced from 1966 through 1986 in both inline-four and inline-six configurations ranging from 1.3 L to 2.8 L. It is a two-valves per cylinder SOHC non-crossflow engine, with an iron block and an aluminium head.
The preliminary version of the 1.8 L (1,798 cc) engine was first seen in the Concept-cX test car introduced in 2007. The larger 2.3 L (2,268 cc) was first exhibited in the Concept-ZT test car introduced in the same year and later used in the Concept-RA test car introduced in 2008. [5] [6] [7] [8]
The 24-valve DOHC 1G-GTE added two CT-12 turbochargers to the versatile motor. There were 3 generations of this engine both air-to-air and air-to-water intercoolers were used, pushing output from 185 to 210 PS (136 to 154 kW; 182 to 207 hp) at 6200 rpm and 234 to 275 N⋅m (173 to 203 lb⋅ft) at 3800 rpm using the air-to-air over the air-to-water.
