High mileage 5k/200t 10v question

[Mihnea Cotet]

Listers,

I've found a cheap engine for my turbo project (I already have an MC-1
bottom-end but I'd like to have more compression so this is why I've looked
for another alternative), this is a 1B engine (similar to the MB engine
from the late 10v urq's, it has 8.6:1 CR) and it has a little less than
200k miles.
I'd like to ask the ones that have already stripped such a high-mileage
10vt engine what state I should expect the pistons to be in....the engine
is said to loose/use no oil at all and supposedly runs well....the owner
bought the car for parts and is willing to let me have everything I want
from the car (complete engine, harness, sensors, etc...) for a timing
belt/water pump swap on his '89 200tq (it's an european car and it's a 10v
model)...
Any BTDTs on high-mileage engines? Do the pistons wear in 200k miles or
only the bores/rings? Can they be worn out if the engine uses no oil at all?

Thanks in advance,


Regards from Belgium,


Mihnea
