help and advise needed on my wrx

hi people i have a 96 impreza wrx. ive not long ago rebuilt the engine as i bought it with a melted piston, ive changed the piston and de-glazed the bore. since then ive put in a td05h turbo, fmic and remapped ecu. i took it to a rolling road to see what bhp it was, the embarresing thing is its only running 174bhp at the flywheel. it was badly misfiring at 5000rpm which is why we couldnt get a higher bhp reading. the guy said its running low on compression on 1 cylinder. when i de-glazed the bore there was a indent about 15mm from the top, could this cause the prob. aslo its blue smoking. can this be fixed or should i get another bottom end. if so does anyone have one for sale cheap as poss please.

Re: help and advise needed on my wrx

bugger,sounds like you have a few probs there bud
the indent may well be causing your issues,it could be sorted by having a re-bore,but can be a costly process,depends if you have the cash to play with,i'd be a bit dubious about getting another bottom end as you never know the previous life of it,but if thats the way you want to go then do it,could be an idea putting in a stroker kit,my mapper has done a few 2.1 strokers,iirc his engine with the selected componants is putting out about 460sih@1.4 bar on its base map..
