Not something that I'm looking to do and a search here came up with nothing, but its just something that I'm curious about. Is it possible to swap in a K10 turbo or even a g13b like in a Cappuccino? Even here in Japan, the AZ-1/Cara still demand a premium so I'm not buying one any time soon (but would love to have one) but seeing the $4000-$6000 bore up kits for the 660cc engine is ridiculous.
I don't think a lot remains of the standard AZ-1 in there, however.
It would be relatively simple to swap a k6a/t or f6b/t as they were both fitted to altos that used the f6a/t.
G13b? My rough measurements say its about 5-10cm too wide with its gearbox attached to fit without some cutting + fabrication. I'd be happy to be proven wrong however!
Not sure about the k10a/t. Anyone with length measurements inc gearbox?
The alto's K10b 3 cyl may fit, but it has less power than an f6a/t.
As for other options, Kawasaki 1400 or Hayabusa + quaife gearbox may be possible, I guess even an old 10 or 12a rotary could fit if you could find a fwd gearbox that suited.
In my minds eye a BMW K1600 engine would be perfect as it's 22 inches wide + 100kg with gearbox. Shaft drive means you could use a normal diff. I haven't had a chance to measure things up properly yet, although I'm sure you'd have to reposition the fuel tank. That bike has only been around for a short time, so I'm still waiting for one to show up at a wrecker

Honda B16a is roughly 150kg with transmission/intake manifold/exhaust manifold/ect attached.
Rough dimensions (assuming youd mount it longitudually): 850mm/33.5in Long 600mm/23.6in Wide 550mm/21.6in High
Length is from crank pulley to end of gearbox. Width is from exhaust heatshield to back of gearbox. Height is from bottom of sump to top of rocker cover.
Unfortuantely to use the B16a gearbox would mean the engine has to be mounted transverse which wouldnt really work. Youd be best to get a transxle gearbox and mate it to the b16.
To make it all fit, youd have to put pretty much everything you could into the front of the car (all cooling bits like rad/resevoir/ect and battery)
That would probably end up being back a the 150kg mark, but i can attest to the honda being able to do 180hp at the crank with a new intake/exhaust/retune. If you open up the block/head you can quite realistically squeeze over 220hp at the crank from the 1.6
Add a turbo and things take a turn for the strange, have seen them push over 300hp with atleast 150hp from roughly 4000rpm and peak of said 300hp at ~8500rpm without changing much inside.
Realistically, better/easier to put the b16 in a cappo though lol.
I don't think a lot remains of the standard AZ-1 in there, however.

I would hope that you're wrong too. The G13b seems like the perfect swap if the K10a/t 4cyl wouldn't work.
Not sure about the k10a/t. Anyone with length measurements inc gearbox?

Wouldn't that be stupid expensive? Or, is FF/MR a cheaper (better?) setup for a motorcycle engine (over say a FR Cappuccino) due to the gearbox/diff being right next to the engine as one unit?

EBAY has one right now for $5700USD Yeah, gonna have to wait a few years for this engine to be more common at salvage yards. Other BMW engines exist now for far less, but not 1600cc and 150hp+.

Chernobyl,
I love the thought of an NA b16 in an AZ-1, sadly it's wider that the g13b by about another 50mm if mounted transversely like the az-1 engine. The width between the Az-1's strut towers is only about 680mm, and about 730mm-ish between the frame rails although that does widen slightly toward the firewall. Longitudinally is not really an option tbh.
ishigakisensei,
"Wouldn't that be stupid expensive?" Sorry - I meant quaife cd diff unit, not gearbox. http://www.autotech.com/quaife/Motorcycle/cycle.htm?main=cyclecars.htm But yes, combined with the engine purchase, things would get pricey quickly. I wasn't really thinking on a budget, just what could be possible (within reason).
Why I like the BMW power unit is that being a 1.6 it has car-like torque, (129 lb/ft) and a 50amp alternator. It is already used in the Campagna T-Rex 16S http://www.youtube.com/watch?v=z-7JEF9o8mc
That one on ebay is missing a lot of its ancillaries and electricals so unfortunately you'd have to source them too. Best to find a written off but whole bike. Anyhow, I have to measure the damn thing properly to make sure it'd fit first

If price were no object then, could you imagine a Hayabusa engine (if it would fit) in there?!?!? Talk about a total sleeper to pounce on the unsuspecting.

A hayabusa engine could certainly fit in a similar manner to how they install them in Smart Fourtwos. Yep it would probably surprise a few people. Even an ecu & boosted f6a cappo or az-1 catches many unaware up to the speed limits.

I was considering the V6 from an MX3, it would go in with a few minor mods to the suspension towers and some serious changes to the rear bulkhead and parcel shelf to allow space for the front bank of cylinders - it's a lot of work for less bhp and more weight than I've got now. I think finding a clutch that will last more than 3000 miles is a better option for me.
Another engine option could be the boxer 6 from a Goldwing, not sure on the power but they do give out decent torque

even with one of these? Sure the end of the gearbox might hang out the back, but the axles should be rouglhy in the right place!

LoL!
At least changing a cambelt would be easily done, it'd be sitting on the drivers shoulder
Could always have that transaxle mid mounted with the b16 in rear / outboard configuration

118hp / 123 lb/ft. I think you'd have to turbo it to make it worthwhile.

I am curious if the Hayabusa engine would fit without having to cut the chassis, just having to build custom mount for it. The hayabusa is a perfect swap for this car, light weight I think wet it weight about 180 lb, can be pushed pass 200 hp without turbo charging it, some people have even been able to push 500hp (turbocharge) with good tuning and for all out drag racing they been able to get 700hp (turbocharge) out of them. Two drawback come to mind. -no reverse -chain drive, so custom work is required to get it mated with the car drive train

That's exactly what ZCars are doing to mine right now, just a modified rear subframe. Not enough height in the engine bay for their standard turbo manifold but NA will do fine for now. They have a reversing drive box that attaches direct to the output shaft of the bussa engine so no chain and reverse.

Hey do you have any photos of it that you can post and if you don't mine me asking how much did it cost you? I my self am going to be swapping the engine out on a cappuccino, I first have to get the car (usa 25 year old car law is making that hard for me) but it will be coming, it will not be a road car just a show and track car, the only road it will touch is going in and out the trailer.

Once I get some pics from ZCars I'll post them. Have a look at their rear engine 'bussa kit for the mini which is basically what they are modifying to fit in the back of an AZ-1. Total cost should be around £13.5K (I know it will rise when I start thinking about stuff like paddle shift ect.) but £7.5K of that is for a late 'busa engine and the drive box.

So 5.5k of custom work, I am surprised of the price of the Hayabusa engine where you live in the states they are can be found for 2000 usa dollar. By the way the paddle shift are worth it, they will make the supercar experience complete
