would a turbo from a mondeo turbo diesal fit my erst exhaust manifold.

 

No.

 

why

 

Two reasons..

1) They don't use a T3 flange.
2) They don't use a T3 flange.

and a third possible reason

3) The turbo is part of the exhaust manifold

 

Even if it did you wouldnt want to use it anyway, diesels use VVT's (variable vain turbos), so it wont give you the power a T3 would, and secondly a standard removed turbo off a diesel won't cope with the stresses of a petrol engine either.

What are you thinking if you dont mind me asking?
