the 996 can be bored out 2mm with the fitment of pistals 100mmbore pistons to get 1037cc or 1068 with a 900ss crank. i have done 2 long stroke 1026 conversions and the number 1026 will only yeild a few hp unless combined with other mods. see brads motoone performance notebook he has just back to back tested a few. i guess going 1037 2mm overbore instead will make better use of the combustion chamber after deshrouding and this MAY make better power than the long stroke 1026 version. |
