Despite what people are saying, if you can get another engine i would do it. Had hydraulic lock on my old VTS and after replacing the bottom end bearing, rods getting the head skimmed etc i had spent well into getting a second hand replacement.
If you wanted it faster, by far the best time to do it but inc the cost and bad weather i had to do mine in, never again.
Retain your old turbo, sensors, gearbox etc etc just get a bare block they got for very little
