Thoughts on Bike engine swaps?
Not talked about much, But I've been wondering about doing a V8 Swap from fusing 2 Hayasuba motors together. They already did something similar with a BRZ but with Kawasaki engines. Seems like a fun build.
Here's a 2.4L V8 made from 2 Kawasaki motors

Money? Gonna have to piece together this one
Talent? Still learning
Time? More than enough to compensate for the other 2
My fab stills are subpar so I don't expect to be able to throw it all together immediately. Time isn't a issue since I work freelance with decent pay. You can get the engine kit from Hartley Enterprises for 29k or assembled and dynoed for 45k. For a long term goal it lines up perfectly, which is fine because I'm stubborn enough to keep a broken 8 even during this shitshow of a pandemic which probably means I'm also stubborn enough to keep it till I die. That pricetag though is gonna keep alot of people away so there's not much info about doing something like this. I was hoping someone already did something similar.

do you have a link to the "kit"? im curious about the mechanics. your two videos are much different, the brz is front mounted and the fiat is rear like the busa swapped (one engine) smart cars

Here's a link for the Hayasuba V8: https://www.h1v8.com/maxi-v8---specs.html
I don't know if its going to have exactly what you're looking for but there is a fair bit of info on it.
As for the BRZ JUN made a kit for the full swap. There is a kit being sold by AJ Racing that is supposedly made by JUN but it costs 106K USD. Here's a link to that kit: https://www.aj-racing.com/?product=j...ine-conversion JUN's website has some info but not much about their kit: https://www.junauto.co.jp/showroom/86brz/index.en.html

It's not going to be cost effective - you could achieve the same performance for a fraction of the price. For what that engine costs, you could get similar power from a less expensive engine and then redo your entire body in carbon fiber and titanium to make up for the weight difference.
Not to say that you shouldn't do it, because holy **** please do it - the Top Gear segment with the Atom 500 is incredible.

What about saving the money and doing a single engine and turbo kit like many of the sand rail/ rzr builds do. A significant increase in power keeping the weight low and cheaper. Heck the r1 motor is well above 200 hp with no boost. Add boost and keep the 12k plus rev limit and have something real special with very little weight change.

Quaife has some solutions for adding reverse to motorcycle-engined cars.
https://shop.quaife.co.uk/catalogsea...oduct_type=&q=
I could have sworn I've seen something that bolts up to the motorcycle output shaft and gives you a reverse gear and a flanged driveshaft output, but I can't find it now. Most of what they have is for a mid-engine setup with the engine right in front of the drive wheels.

this one didn’t end so well, guess it all depends how big the fire is that’s burning a hole in your pocket:
https://motoiq.com/project-miatabusa...e-we-thinking/
more often than not it will cost way more than most people consider, not that it matters because the people carrying on about it are typically the same who can’t afford it.
Otherwise they’d either just be buying a supercar or building it already rather than gabbing about it. The truth is usually more obvious than people want to admit.

1-rotor Porsche speedster build; unfortunately the 3-Stooges building it are why the rotary is often knocked when it’s not the engine that’s at fault

Cool and unfortunate at the same time. They haven't posted in a while unfortunately. I'd love to see it continued. Sadly I am also a Stooge when it comes to complicated stuff, but hopefully I'll gather enough experience messing with my car while I piece together a build. Right now I'm swapping my RX8 Transmission to manual, but that's not that hard to do and I'm gonna need alot more experience to get good enough for something like a hayasuba swap.

I know this swap sounds like a pain in the ***,
H1:

LS:

The H1 is 5" shorter in length, about an inch narrower, and about a foot shorter in height, not counting the intake stacks. Seems like it'd nestle down in the engine bay nicely.
