Engines are more common than the CA18DE as more where sold and the
1.8 litre version the QG18de is the one to go for used in Pulsars
throughout OZ until 2005.
The ignition is the issue but easily solved with megalite jnr kit
There was one on a 120y somewhere but posted on an American site
yet the converted 120y is supposedly in Australia.
Probably the same weight as the ca18 as it has a chain drive but
very compact dimensions.
The americans boost these engines alot.

The issue is pollution gear.
