Smallest turbo that is readily available used?
 

I am needing a very small turbo, what is the smallest that can be semi-readily found used and what vehicle(s), and/or engine(s) does it come from? Maximum mass flow rates needed for the power goals will be around 17 to 18 lbm/min.

1.8t VW's there tiny

depends on how small. the TT 3000gt's have pretty small turbos

It's going on a 500cc engine that will turn up to 11K rpm. The GT12 and GT15 garrets would be fine but I'd rather spend a bit less. 17 to 18 lbm/min is a very small mass flow rate. What type of turbos are the stock 3000gt units so I can find compressor map and check if they will fit this application.

I think you need to give us some more info. What kind of powerband/peak torque are you looking for? How much does this vehicle weigh? Etc...

they are a tdo5.

I had a VW Bug turbo that was pretty damn tiny, not really worth putting on the car.

I could be wrong, but I was under the impression that the 3k/stealth came with TDO5-9b turbos???

Heres a good site with a few MHI and garrett compressor maps and other stuff that we should know but few care about.

it may be but on the compressor housing it just says TDO5

Weight should be around 250 lbf, power goal is 125 max at the crank.
