Id advise a polo 6n 1.4 lump. Im not tht clued up but there a wikid little engine and throw 100bhp standard but are 16v so if your looking for cheap inscurance thats probably a no go if your under 20. Failing that ive got a 1.6 lump out of my mk2 tht is free game if your in need but will need rebuild and new stems atleast.
