I was wondering if anyone that has used these bearings knew how long they last compared the the ACL Std bearing set or even OEM bearings. I heard the ACL Race bearings have a shorter life span and seeing how i wanted to build a Long lasting and reliable B20/Vtec revving to 8k, i dont want to have to put new bearings in it 40-60,000 miles down the road. This is just a general question about the ACL Race bearings, not how to build a motor to last for XXX,XXX amount of miles and how my motor is being Driven, Built, and what parts are installed.

Thanks for all the help.

 

it depends on how you clearance the motor.

 

They give more clearance / looser and have a coating. That's all. Same material

 

used them on a b18b, and had rod knock on cylinder 3. i'm using Calico's on a build now.

 

What did the clearances work out to?

 

i don't remember, everything was written down and i lost the paper work. the crank had a smaller diameter on cylinder 3 and 4 and i thought that i'd still have enough for the bearings too work, but it didn't lol. 4 was fine, but 3 was knocking bad. standard size on the crank is 1.771" if i remember correctly.

 

Was the crank turned to your knowledge? I have tune plenty of motors and know people who have used ACL Race Bearings without issue. I personally stick to or use to stick to Honda OEM bearings but there is nothing wrong with ACL bearings

 

acl race bearings are the best bearings you can buy..they take alot to make them work perfect they will outlast stock bearings...but you must have a SPOTLESS crack to use them and i would not use them on stock rods only hbeams"but thats just me"you CAN NOT TOUCH THE BEARING WITH YOUR FINGERS AT ALL!!!!!and your crank must be polished and within spec...but as for them lasting your info was wrong they will last..

 

thanks for all the info guys

 

apparently it was and i wasn't told. i've heard good things about them too, i've just had bad personal experience with them. same thing with the XTD clutch i had, heard alot of good things about it but it doesn't last 300 miles. i've never bought OEM bearings for a build simply because i believe aftermarket to be better for a "built" motor. i'm using Calico's now so i'll see how they go.
