Hi PowerhouseRCperformance,

I have a question,when a sleeve gets modified,ported,and cut does the integrity of it deminish.
Does it still have the solid foundation it once was.

I'm just asking,because someone thinks once an engine is modified,it loses it's reliability.And all I can think of is that for it not to be reliable,is that the sleeve has been structually weekend.What are your thoughts...
