I think it's something like that. The end of the crankshaft has worn.

The car suffered a worn camshaft causing the cambelt to move around. The parts that fit into the camshaft were replaced so it now idles properly, but when you put your foot down and expect a surge of power, instead it revs up without gaining speed until something clicks then your off again.

Yeh I did see that Marcus but not sure if it would seem as powerful? Then again it does sound a decent spec. How much you after? It's giving me a headache now though. Do I keep it running like this or go for a new engine/turbo. Trouble is ive spent around £750 already and it's still not right

worn crank will knock not cause power loss

Maybe I'm not describing the power loss correctly. It doesn't 'lose' power as such, just doesn't really gain any when you accelerate at certain revs. Like I say the revs rise but the car doesnt gain speed, then all of a sudden its as though something connects and everthings back to normal. It's as though something's slipping.

Find out exactly whats wrong with yours first mate, no point splashing out till you know just what the problem is & feel sorry for you having to spend so much & getting nowhere,
must be very frustrating.
Im not in a hurry to sell my old engine as it's not on Ebay or Gumtree,
least you know it's here if you need it.
Ritchy put the same cams into his 1.6 & can vouch for increase in power,
with Z&F map it will have been quicker than your 120.
The option of you trying for a cheeky trade in might not be a bad idea &
would get you some of the money back you have already spent
