hi everyone I'm new and need some help please, what engine is fitted?

I'm new on here just paid and i have to say what a great site,I'm after some help i have just purchased my first golf mk1 it was a non runner as the bottom end was seized, the person i purchased off said it had various parts on but i have no receipts for this he said it had a 2.0 audi e bottom end mk2 16v gearbox/and a tsr pack c head (i do have a receipt of this), would any of you know what parts this has got? I've removed the engine now and want to get it back on the road asap but not sure what block to buy or even if the head is any good and what engine is best to replace it with your help will be greatly appreciated, thank you.

Weird to see a Mechanical Head on a DigiFant engine.

Like the Multi-colors that it is rocking.

You head has 5 Journals over the Cam.  That is indicative to a Mechanical head from a mid 80's 1.8.

Whereas the later 1.8 engines had a 4 journal head that should be missing the Journal from the number 3 to the end. which would indicate that it had Hydraulic Lifters.

The Control module for the EFI is also not stock, and I am not sure of the make, as EFI on a Digi was DIGIFANT II, or DIgi1 which is seen more on the pre 91.5, and 89 California Equipped 1.8 over here.

That is it is also rocking a water cooled Oil Cooler which wasn't on the Cabriolets in the 90's but on some GOLFS and JETTA, and Passants from the 90's…. SO I say you have a Frankenstein engine of sorts…  The Fuel rail is more 94ish, than a 90's Digi as well,  The Fuel pressure regulator is a different type than is seen on the MK1 90's platform.
