Complete ( exhaustive! ) car history, with hundreds of photos, is available on my
Website, documenting original build as well as the twin engine conversion.
This is one of the few wide body twin-engined cars around and is based on a '99 SEi wide chassis.
Considerable time and effort has been spent on this car improving it's performance, handling, and reliability
over and above the "standard" Z-Cars spec.
Car is currently setup for fast road/track day use, and is fully road legal.
