My motor sans turbo, downpipe and muffler weighs under 120. The transaxle is 70lbs tops. I figure 225 complete and full of coolant.

The whole car weighs in around 1400lbs

And the Goldwing is replacing your motor with one that produces a lot more HP.

The last dyno I saw of a Goldwing was almost identical to that of a Miata.

How about a Rocket engine in a Triumph Spitfire? Triumph on Triumph goodness there

In reply to FlightService:

That was the first thing I was thinking with the Rocket III. I was a bit bummed that I couldn't do it in Street Mod under the umbrella of Triumph Car, Triumph Engine. Turns out they specify a car engine

Would've been awesome, though. Sequential gearbox, 140 hp, 150 ft-lb torque (at 2500 RPM!) stock. That'd move a Spitfire right along. And then there are the forced induction kits... I do wonder how tall that engine is, though. And what it weighs...

How many other like-brand motorcycle engine/car body swaps could there be? Hayabusa-powered Swift under the Suzuki banner? Blackbird-powered Honda N600?

Yamaha R1 powered SHO?

Ultra complicated way to make the same power as stock, I love it!

Revived on purpose.

For $100 you could go down this path.

Engines from BMW K-1200LTs have reverse in the transmission, where early GWs used the starter motor spinning backward. Weird but VERY helpful when you drop the nose off the edge of the parking lot. I think both have about the same low center of gravity.

Have you looked on ebay?

Also poke around Naked Gold Wings (NGW). They're a lot like us only with Wings.

Goldwing inside.

10 years after this thread an absolute legend in New Zealand has gone full Allan Milyard and is undertaking this idea in the best way possible including deleting the goldwing transmission and associated gears and shafts from the flat 6, machining the case down and mating to a transmission in the back of a Hilman imp.
