I think i've come to a decision. It is to wait and see what i think of HandyAndy's car once its finished

, if i like the speed then i'll be rebuilding my 1.8 CVH, if i prefer Spud69's car then ill be going for a brand new zetec engine. As i've just been going on the point that more power = better, which i may not actually find it to be, the slower i go the more mistakes i can make

. And a few people who have upgraded from a 1.8 CVH to a 2.0 zetec say there wasnt as much difference than they hoped, and that to me isnt worth £800 more.
In the mean time i'll continue cleaning up the parts, but not spending any money doing so and researching the zetec engine.
