what version engine is fitted to an x reg uk turbo?

what version will be plug and play basicly

 

V5/6

 

As above.

 

Is there any difference on the bottom end between versions? Pistons crank rods etc

 

UK Turbo's don't have versions!

It's a phase 2 engine, open deck block IIRC.

 

+1,

 

Ok cheers would a phase 1 block fit instead of a phase 2?

 

A phase 1 has the smaller 330 grey injectors not the yellow 440s like your car will have. The coils are also in a different location :S . Any engine can be made to fit, a phase 1 engine or a phase 1.5 won't be a straight forward fit, the wiring loom and ecu are different too. Why are you changing your engine? I would suggest fitting a jdm engine, (they have different inlets, different cam set ups) so overall it would be a stronger engine if its backed with service history.

 

pistons are wrong to have the correct compression when mated to ph2 heads..............
