trust me, i had an OEM built GSR with ACL bearings 5 years ago i revved to 9900rpm with no problems, motor lasted 55,000 HARD miles.

My 2.0l LSVTEC had ACL Race bearings but it was arace motor.

Ive built 3 or 4 other engines for friends with ACLs that still run to this day, and made between 170-190whp depending on their mods.

The majority of the industry uses ACL bearings as well. What you do is buy the ACL Bearings, plastigauge and make sure your good. If for some reason you are out of spec on one, you buy the bearing you need from honda.

But CHeck out Honda-tech you can find the ACLs for cheap. OR hit up Mainstream Performance, they usually have sets in stock
