Race Engineering stocks both stock (83mm) and 83.5mm pistons. If you look again, you'll see "bore diameter : 3.287" which is 83.4898mm ('s a 8, not a 6)biosehnsucht wrote:If you look closely you can make out the bore diameter on the spec sheet is "3.267", which is 83mm. They're stock replacements (hence why he got them so fast - they really DO stock them )
motor shop recommendation. They told me that piston to wall clearance was almost twice maximum spec and that oversized pistons would be the solution.boost_boy wrote:Congrats on the purchase of the CP pistons! Why did you chose the the 83.5mm slugs? I chose the 83mm because I had no bore damage after 3 years of hard-core abuse. Anyways, good luck on your rebuild.
