I would like to see the power graph, It dose sound optimistic if you dont mind me saying, but fair play to you a 120bhp 1.4 wont be slow they rev quicker than the 1.6's I thought.

nope, genuine 1.4, loook at the second page on the link on AOC i put at top, it shows the graph from rolling road.

The head was skimmed becus the head gaskets gone on it twice, so im not sure how much they wud have taken off?

it pulls so well now tho! and thats without a remap, atm it needs remaping becuase its overfueling like mad! also the bottom end berarings need doing as i can hear them knock a bit.

I don't think you can re map em just chip em iirc , if its overfueling and the big ends knocking I can't see how its makin 120hp how good were the rollers ?

A power box gives you 10-11bhp

My old 1600 16v, with decat/exhaust, powerbox and set of Kent cams made 127.
