I have a 190xt that needs a different tubo it's using oil and the intake is full of oil it has a to4b80 on it but I have a parts engine that has a schweitzer I think that is correct on it. My ?? is what turbo is better I also have one with a Garrett rebuilt tag. Should I look for another to4 or Garrett or Schweitzer. There are new options on Ebay for $350 to $450 but not excited about china turbos thanks for any recommendations. I know of a few m2 for parts and L2 but not sure what turbo they have.

T04-B80 is an Air Research (Garret) and is from a 200 tractor era and are fine. The Thompson (Rajay) are inferior in my eyes but still work fine. If you change brands you have to use both oil lines as they aren't the same. L2-3 combine might be a 301 engine and you cannot use a 426 turbo. Installing a used turbo, it better be exactly positioned and clocked the same as yours or you will never get it mounted. 50 years of rust and you will twist off bolts and fail.
