World's first rear mounted Honda Goldwing flat six engine swap.

First drive of my Imp with custom built Honda engine and Subaru transmission. This engine and transmission build had many experimental aspects to it and I was not going to know if they worked until I drove it. Very happy to find out that it all seems ok. It was a very wet drive and the engine is not yet tuned properly so I had to restrain myself.

There are some teething issues I'll have to sort out and I'll be writing about those in my next build thread update that you can read here...

Basic details of this engine build are as follows....

After stripping it right down I chopped the casing down in height, removing everything below the crank. I then proceeded to remake the engine to suit its location and bolt up to a subaru Leone transaxle.

Custom parts I've made in our workshop include..

Crank case lower and easily removable sump cover to suit.
Oil pump system remade completely starting with original Goldwing pump, turned 180 degrees, driven by custom sprockets and a sturdy bmx chain off a custom crank hub. New oilways and oil filter moved to the side of the block on a custom pedestal.

Custom flywheel with subaru ring gear.
Custom bellhousing to suit Subaru Transaxle.
Subaru clutch disc, Honda prelude clutch cover.
Honda civic starter and alternator (goldwing engines rotate anti clockwise)
Custom inlet with welded on injector bosses. Custom brazed steel sidefeed fuel rail to suit Nissan Micra injectors.
Custom inlet plenum where originally there sat two carburetors. Honda integra throttle body.
Custom stainless steel headers, matched length. Custom front plate with engine mount points.
