lol, i used to have a 2litre mk5 cortina ghia as my first car, it had a 1600 replacement engine in it, so i did a bit of trying and testing as a youngster looking for more power, i ended up removing the head, polishing all the ports, re-grinding the valves, putting a 2litre camshaft and followers in it(i measured them with a vernier and found they were a couple of thousandths of an inch bigger and the lobe angles seemed all the same), put a set of twin choke webers on it(standard 26/27's and re-drilled both air jets to 2mm), put a janspeed exhaust on it with a peco power master back box of a mini on it, holy crap it went like f**k, at the time i was keeping up with sri's and xr3i's, it was quite amusing to be honest, ahh, them were the days. lol
