I'm thinking about the oil filter support.
Starting with things I already have at home, I can work it out from some scrap aluminum bar slice I have (where I worked until last year we do thousands of parts of 105mm diameter, and unfortunately -for the factory, but fortunately for me- every standard bar left about 30mm of scrap, that I collect instead of throwing it away).
I also have a piece of M16x1.5 threaded steel bar.
I can use it for the filter, but that means I can use only one type of filter in the market, used on the old Citroën 2cv or some other small petrol engines.
I can't find informations about the filtration capability of those filters in micron.
In your opinion, it can be good enough for my project?
If not I can even work another threaded part on the lathe at work, but is more simple for me to use the M16x1.5.

Temperature controller for EGT arrived in 10days from Ontario with standard post! Next time I want to do a trip I have to consider the possibility of being shipped in a box 🤣  |

Any proper engine oil filter should be ok for a turbo oil supply.
You can often buy "filter relocator kit"s very cheaply, which have a filter mount and some AN fittings, and usually use the most common 3/4" threaded filters.
Many engines also have the filter mount as a bolt on part, which makes it easy to modify for our purposes.

Thank you, I'll go for the 2Cv filter! |

Watching on eBay for rebuilding kits for my K26 turbo (it is functional, but it have over 250'000km on it, and the compressor wheel have some damage), I came across a NOS unit, with original caps on the ends and in perfect conditions.
I bought it, for 100€.
It seems a good catch to me.
If it is not the right choice for the job I can even sell it.

Fast like a...turbo, the turbocharger arrived today! It is simply new, even if it have 32 years, it have all the outlet and inlet closed with plastic caps and it is oiled. After a few measurements I see that it have a 43mm compressor inducer and a 55mm turbine exducer. It is a 40% smaller area, can it be a good candidate? I hope yes, but I read that John says that a 20% is the right number. For sure it doesn't have surge problems 😂 It have all the features I need, a flange outlet so useful to attach on it the jet-pipe and later the freepower casing.     |

Hello Davide It Will run very hot i Think with such big turbine. /Stephan This can be a big issue. Maybe it is possibile to do the flame tube with bigger diluition holes and maybe a little bit longer than expected to reduce the problem? I don't need to build the most powerful turbine, just something able to run a small freepower turbine with few hp output. But...maybe the compressor can have a big efficiency? Just asking. This turbo, on the engine from it comes, a 2.5DI diesel, give 1bar boost, and sometime it is tuned to give up to 1.2 bar without issues. I know it because it is the turbo of a veichle I know, the Fiat Ducato 2.5TD. I was surprised measuring only 43mm inducer diameter, knowing how much air that engine sucks! |

Maybe to fill out incoming air from compressor with water/methanol injection

I don't know, maybe it is better to try to sell it to buy a better one.
I decided to buy it even if it is a risk because I think I can sell it at the same price or maybe more (there are a lot of camping-car based on old Fiat Ducato here).
But maybe the fact I want to run it on LPG, and making the flame tube a little bit longer to avoid flame to reach the turbine can work.

A wastegated turbo isn't usually much good to us....and it's very small at just 43mm.

I'd use it as is , the turbine flow might be controlled by a "tight" scroll housing , without knowing the exact sizes its difficult to say if its a usable turbo , but generally diesel turbos work OK ..............yep , no problems with surge :-)

I need to build a small one to start my journey in gas turbines! Then, after this, maybe I decide to give life to the HX60 I have in my parent's garage since 2006! A wastegated turbo isn't usually much good to us....and it's very small at just 43mm. Smithy. |
