OVERbore folks
There has been some recent debates on whether the combustion chambers should be matched to the size of an overbored cylinder. Traditional thinking would say, it should be matched(to eleminate any possible hot spots/detonation)- but I've heard people are running fine with the stock sized c/c's and bigger cylinders. What are you guys using and have you had any problems with it? TIA

Re: OVERbore folks (TurboDANDEE)
real heated debate about a year ago here: https://honda-tech.com/zerothread?id=156070
Some say, and I agree changing the cumbustion chamber may hurt performance. I have an 84mm bore with 81mm head and it works just fine.

Re: OVERbore folks (RAWB)
Consensus = Leave the c/c's alone.
Also, what is the relationship of displacement of a B18C bored to 82mm(1842cc) versus a LS block stock bore(1845cc???) I've noticed LS/turbos still push more torque compared to bored VTEC/turbo setups.
How much of a difference is there between an engine with different bores pushing the same boost on essentially the same head/engine management setup?
