In an honest world teh recon should be as good as new. What you are paying for are the replacement of worn parts and labour.
Buthere's the rub.
What parts are actually replaced ? What is the quality of the replacement parts ? And how are they fitted ? What testing takes place before it leaves the refurbishers ?
Now to do a quality job all costs money and none of us want to pay that. So at one extreame you get few, low quality parts replaced by a monkey. Of course all finished off with a coat of (unnecessary) paint to make it look good.
So in short, you need to understand what refurbishment means.
Sorry if this is obvious. But, I've heard too many stories of peps fitting refurbished engines/gearboxes etc in their cars and wondering why after 5000 miles something has failed. And of course it's not covered by the warrenty.
In one case, the oil pump failed.And that nackered the engine. It was not changed as part of the refurb.And not even checked to see if it was suitable for future service.In fact it ws likely that this pump contributed to the demise of the original engine.
As for the turbo...........Not sure what I'd do to be fair.You could fit the refurb and flog the car. Or get some idea of what refurb includes on this turbo.It should include new bearings and seals as a minimum.And as a maximum not much more. These are precision pieces of kit that rotate at high speed. Get it wrong...............Forget to change the seals, and your car starts to use the lubrication oil as fuel. You have no control over this what so ever. Don't bother turning the engine off via the key.It doesn't work. The engine stops when it has used up all it's oil.Then seizes.
