I can turbocharge ANYTHING!
Probably drive it around the neighborhood a bit, I have an older Honda VT600 (VLX, Shadow, that sort of thing) Cruiser that I ride around most of the time. At least the turbo will end up on SOMETHING.. hehe..
If its fast and stable enough to ride for real, I'd certainly ride it all the time.

I found (and purchased) an even smaller turbocharger.
One of these two turbos is likely going to be used on the project, the other might end up as a conversation piece on my desk (or another mini-project)
Small enough for you?

Good luck on your project and business.
There is a guy here locally that successfully turboed his sons dragster engine. The HP went from 17 to 25. It is still the smallest turbo I have seen. Its an IHI turbo originally designed for a 2cylinder diesel bilge pump for a barge. A nickel will not pass into compressor inlet.
Its really hard to tell in pictures whos turbo is smaller. Comparing compressor and turbine wheel size would be far more fruitful. If you have the time to measure them that would be great.
From the looks of that build theres a few flaws in the design. My guess he had other trouble building boost properly.
However this particular turbo is about the same size as the one in the photo, its hard to tell though they do look very similar.
Anyway, it turns out that bloushturbo had done something similar on a pocket bike with a 100cc or so engine, they did have trouble building enough boost, but this setup is a similar turbo, and an engine nearly 2x the size, so it should do somewhat better..
The big problem with doing something that isn't commonly done is the fact that you are dealing with a huge amount of unknowns, but that is what makes it fun.
I'm starting with a cool looking bobber kit, and at the least doubling its displacement with an aftermarket engine. I'm adding another gear and improving its gear ratio which will give it some more top-end. If the turbo doesn't work out, at least I've gotten that much out of it.
Regardless the entire point of this is to build something that has a bit of "Conversation factor" when people see it, they'll ask questions, and that is what you want ultimately.
This is actually the smallest turbo I've seen, and according to some of the data I had, it was designed for a very small displacement motor. (I think it was an OE turbo on a diahatsu 3 cylinder engine or something like that.) And the challenge of figuring it all out is way more important than whether or not it ultimately works exactly as planned.

I agree with you on the monkeyrun project. Although I think he did a really good job at fabricating he could have made a small mistake somewhere that hindrered it all coming together. While it is cool to embark on these projects with the idea that if it doen't work that great than so what? its still a good coversation piece. I am following such projects because I have always wanted to turbo something small. But I want it to actually work well.
Looking at the monkey run turbo. Thats a TD02. There are three smaller than that. TD15, TD13, and TD10.
Here is a mind bending idea of how many different turbos there are. This is just a mitsu catalog.

Now those are small. Who makes those and where can I get one?

Once I get all the data on it (when it shows up) I'll be able to post more info. I have a compressor map for it, but its not very useful to me as I don't know the characteristics of the motor I'm using all that well yet.
Both turbos are very small, its hard to tell if the other one is much larger or roughly the same size.
Ya know the hardest part of the entire thing is the oiling system. As far as I can tell the small displacement Lifan engines don't have any sort of pressurized oiling system, so I'd have to devise a small pump, and circulation system for it.
It does look like the inlet actually has the same exact dimensions of my 30mm carburetor that I will be using which actually removes a bit of fabrication.
Right now I have the engine showing up monday, the turbos at the end of the week, misc parts coming around the same time, and the lead time for the bike kit itself is 2 weeks so I should get that shortly. Until I have the bike on my bench, I can't do any sort of measurements or whatnot. Most of my stuff was based on "Gut feel" and some rough dimensions provided to me through taking a measurement of known objects in the pictures and putting it in scale accordingly.
IIRC the JDM market had what was termed "Kei" class cars <700 cc and turbocharged, ~100 hp but not sure what size turbos. The above ones look too small for that tho.
Can these be used on 2 cycle engines without risking the crankcase ? Or blowing out the seals LOL

how much does a small turbo cost? I have a 25hp two cylinder diesel 
tractor and I live at 7200ft so it's quite a bit down on power. I'd love to slap a small turbo on it and just get the lost hp back (which seems reasonable from a fuel and reliability standpoint).

im subscribed!!!
very cool. im always into different things, yea om that guy that still feels a good place for a turbo busa motor is between the fenders of a mango body corrola!!!!
well good luck and i think efi would deff. help for all the obvious reasons

First, the engine I'm using is a 4 stroke, in fact almost all of the pocket bike engines are 4 strokes now.
From all the research I had done, the IHI Turbo (in the first group of photos) was a turbo used on a small car, a 3 cylinder very small displacement, like a daihatsu or smart. I also think some very small diesel generators used this turbo.
The second turbo is way too small, it probably was used on a small displacement generator engine also, It also looks very very similar to the turbo used on the old Honda CX500T (either of them could be the unit used on that bike) (http://users.monash.edu.au/~jhovel/cx500.shtml)
