when i said the lands were broken i shouldve specified, the lands were broken below the first ring and below the seond ring ill take a photo.
dizzy is electronic stock a15 import one, has been regraphed to i dunno what specs as i dunno what they do.... jeff says its regraphed for turbo but i dunno what that means. i didnt have vac avance conectted to manifold. boost was only 7psi, comp ratio was around 8-8.5 to one, again this is what i was told by jeff taylor as i dont know how to check.... although a fair amount has been removed form the piston so i belive it would be around that.no further material than the stock depth was removed only the dish was made a larger diameter pics below.


ok this pic shows the lands where theyre broken, notice theres no yellow or white spots to show white hot lean out.... only thing that worries me is the scuff marks on the skirt i dont know whther i did this when taking it out or whther there is tighter clearance there, maybe the lands caught the bore? surely rings would go before that happened???


the small crack looking thing on the left isnt a crack is just dirty part or something. notice theres no damage only a few tiny little pin-dot marks from detonation ( i was told thats what it is) theres also no spots that would show lean out. the sides above the rings of the piston are completely black same as this.
