The Nissan CA18DET is a turbocharged 1.8
liter (1,809 cc, 110.39 cubic inches) straight-4, four-stroke cycle
gasoline engine from Nissan CA-family. The motor was produced
from 1985 through 1994.
The Nissan CA1D8ET turbo engine has DOHC (dual overhead camshaft) design with
four valves per cylinder, cast-iron block, and an aluminum cylinder
head. The engine is equipped with Multiport Fuel Injection system and
single Garrett T25 turbocharger. The engine was available in two
versions: with intercooler and without it. This engine is similar to the
natural aspirated variant - CA18DE. The CA18DET motor has an 83.0 mm
