VW AAZ K24, turbo choice

[srednA]

Hi

I have a VW Mk1 with a AAZ and a K24 turbo. (Item 068 145 703 c)

I need to buy a new turbo and was thinking if it was some other maybe better turbos on the market for easy fit instead of K24?
K24 works great on the car, but I need to buy a new.

Yesterday my motor made a big grey cloud of smoke when drove it.

It was much oil in exhaust pipes and IC pipes.

Turbo (16psi) and temperatures  is normal when I drive the car.

Thanks
