1.8 litre Turbo engine
Here is a little history on how the Nissan CA18 evolved in our Cortina.
..................................................................................................

The Story
Originally we fitted a non turbo CA18 engine to the car, but soon wanted more power. A year or after in went a standard turbo engine. With this engine we were able to run 8.2 second eighth mile times, which is about 12.9 second quarter mile time. We were pretty pleased with this. We then decided to go for even more power. Never ends, you always want more power :) Read on to find out more.

With aiming for more power we had to rethink all aspects of the engines operation. Looking at all components inside and out.

The engine was built by Geoff S. (Shirley Engines) Internals with exception of a couple of Japanese sourced parts were all made here in Australia. Car is still a regularly driven street car.
