stroking is a good way to gain some horses and increase displacement, but there are better ways. see our cars have a lousy rod ratio meaning we have a high mean piston speed at our redline. this puts stress on the cylinder walls making them proned to having a rod go through them. a better way to increase displacement is to bore it out. use a aftermarket set of sleeve a that will support a 84-84.5mm bore keeping the stock stroke and also rod length. this will allow you to rev higher than the 8k that youll get with a stroker kit with out risking putting a rod through the cylinder wall. if you want some literature just pm me and ill send you an great write up on this matter. it is at home but i can scan it tomorrow and email over to you. it will really help you understand what im talking about and also give you some insight as to faults of these motors.
