Hi
I am starting an golf mk1 crazy project

)
and would like to ask you some questions...and I request for advices if the idea is good..or what should I change?..
So week ago I have bought the Mk1 Gti golf with 1,6L injection engine and 4speed gearbox...
The project is to put the 2L 16V engine from mk3, totally take everything out from the car except 2 seats and dashboards.
Install VR6 brakes to the front, lower the car, install + 150HP NX system. I would also like to change the engine parts with stronger materials...pistons (for example from jepistons.com) Please advice me if it is possible to buy those parts in UK ( I have family in London)
and what would be the about price...
I would like to have around 160HP without NX and around 300HP with Nitrous.
I write from Poland so sorry for some mistakes
best regards and awaiting advices
