K836EYP - Dead

[measor]

Im gutted, only 10 days away til i move to ibiza for the summer and my valver dies :( got my mate to have a look at it after some quite disturbing clunking noises coming from the engine when i reached 3000rpm, verdict "the big end bearing is f****d."

Now I was always intending to replace the engine in the future with a 2.0 but that was way in the future. I reckon my car will be off the road for close to a year as I save some money and get everything sorted, (widetrack, shocks, brakes, paintwork etc.)

I would like to know what sort of price im looking at to get a rebuilt 2.0 put in, I wanna get as much power as possible but cant afford throttle bodies or a turbo conversion. My gearbox ive got at the moment is less than a year old (recon from renault) from what I understand it wouldnt last long on a 2.0 engine so does that mean ill have to fork out another 750 on a new gearbox?!
Any help, tips or suggestions would b great!!
