Mr Wizzard - can you or anyone else here add what you feel would be appropriate clearances for both main & rod bearings? thanks in advanceWe've done a lot of testing over the last few years on this (supposed) bearing situation, and I've concluded that the problems seem to only occur on engines built with too much bearing clearance, assuming the oiling system is working correctly.
I heard today that the k-series bearings are too thin for big boost and big power. Does anyone have experience that the high compression + boost = smashed bearings?
I plan on running 5-7psi on my stock k20a with 11.5:1 CR and a small turbo like gt28rs.
So from what i have read, is that its no big deal about what bearings to use, just make sure the gap between the rod and crank, + the gap between the crank and mains, Is proper. I am debating right now over ACL's, and OEM.
:wow:We fit bearing clearances to tolerances of less than .0001". I refuse to build Honda engines with aftermarket bearings...but then again, we unconditionally warranty the race engines we build.
