hi all, i'm new! i was recomened this site by a mate

I have a mk1, but it stared makin a knockin on the top end, took it in to a vw garage and they tell me my small end has gone and it would be better to replace the engine, so......
I am thinkin on a 1.6 maybe, mine is a 1.8, will my gear box fit?
or maybe a 1.8 driver engine with a single 45 or twin 40's??
Any ideas as long as it wont cost the world??
Any one got an engine for sale?
Cheers
