Depends on the camshaft and tune but to beat a 80kg heavier golf mk1 with a 2L youll need a fair bit of poke and best go for A15 crank and bigger bores at least closer to 1600cc.

Depends where you are but a place I go to are able to use e15et conrods on offset ground A15 crank using custom cast pistons for 84mm stroke and 82.5mm bores on sleeved A14 /a15 block. 1796cc yet at the end of the day supercharged A15 is better.
