Turbo 4-stroke 125cc engine
 

For my engineering tech project for school we are going to turbocharge a 125cc mini bike, thought it might be fun. I have seen a few threads on here and have searched through them but i cant seem to find a turbo small enough. Because its for a tech project we have to get the proper seized turbo and justify it with all of the calculations and that bs. I called garret and they said they have nothing and i called turbonetics and they said try a garrett haha. But i remeber a while back see a picture of a couple turbos next to pop cans and they were really small, they looked about the right size for this project, so im just wondering if anyone knows about the pic that i am talking about, and what they are called, so i can then get the compressor maps and figure out which one i need. Dont recommend any car turbos because they are all too big and this need to be done "properly" to get a pass. here is a similar bike that we are going to be working on

yeah try the ihi turbos have seen some really small ones but not sure kkk turbos oh and def post pics this should be a cooll project

Ask Frank to look around in some of the Jap yards or one of the Euro guys since alot of jap and euro small eco cars use tiny engines with tiny turbo's. IHI will probably be what you end up with for the maker of the turbo.

Yeah i have been calling arround, and it seems that the IHI RHB3 is the smallest of them all, the problem is that IHI does not like dealing with aftermarket customers and for that reason i can find a compressor map for the thing. Anyone know where i can find one??? im not sure if if these come stock on any vehicles, but if anyone overseas wants to take a look for me it would be greatly appreciated, i cant see these turbos being in that great demand seeings as they are so small. i think im also gonna have to slap a few hmt stickets on the bike

PM Junkyard racer and Frank could probably find you a testicle sized snail and won't be that expensive either like if you bought one from IHI or any other company and pay retail and miniature turbo's aren't cheap either.

Does anybody know about that pic with the turbos beside a coke can that im talking about???

Re: Turbo 4-stroke 125cc engine
 

I'm not sure the pic you're talking about. But a KKK off a 1.8T volkswagen should be fine the inlet is tiny like the size of a quarter. That motor would spool it easy. B20Accord and I turbo'ed a go kart that has a 8hp four stroke tecumseh roto tiller motor using a Td04 off a wrx and that motor made boost at the top end. That turbo is also bigger than the KKK. That 1.8T turbo should do fine.
