Have some questions for you gear heads. I will be fixing the base gasket leak on my '07 this winter. I could just do a re-ring but how about boring it out as big as it will go with maybe one bore left for safety ? How thick is that cylinder liner and how many oversize pistons are available? Can I gain 5 or 10 cc with boring the stock liner? Also if I re-bore shouldn't I also do a valve job? That would be OK with me as I could do a minor port and polish job while the head was down. I don't have a lot of money but like working on motors. I also don't want to pump it up too much and loose any reliability but I'm thinking a few more cc's and a little better flow can't hurt. I also want to keep it simple, so what do you guys think? Your advice will be greatly appreciated.
