OEM vs ACL bearings

So I've had my crank checked and measured and been told that it just had a polish and that I need the standard size bearings. I was planning on getting all OEM to get exact clearances, and for piece of mind.
But now I've been told I need all standard, I'm wondering if I should just get ACL?
There is a HUGE price difference, but I'm happy to pay the extra if I needed to. Now it seems like I dont really need to, as if im right, the ACL is the same as the green size oem bearings? (are standard ones even green? I dunno lol)
 
Do you have the block?
The colours can be found by using the code on the block and the code on the crank by the journals.
The book was useful afterall!
 
Bearing in mind (pardon the pun) if you are to go down the OEM route, be prepared to spend a lot. For crank bearings on my build I was near £300 from Lings. that was without rod bearings.
Also just because the crank measures out ok, the block might be slightly different.
as John turbo says above check all the markings and look them up in a Honda manual.

if the crank has been polished you can disregard this way of doing it.
Polishing removes material.

If the machine shop has measured then go with their advice.
 
the OEM bearings are going to be a fair whack over £400..I can get the ACL for under £100
the crank isnt the one from the block I have, but should be the same. Also, the machine shop have my block anyway.
If the colours are all different, does that mean the standard bearings are different sizes?
 
Have they measured everything individually?
Your machine shop may not be familiar with Honda bottom ends and all the different size bearings.

On a lot of other engines you will just get standard and undersized bearings rather than all the different combinations to get perfect clearances

He's built a few but I can double check.
I'm feeling pretty lost with this tbh :( lol
 
Got my honda oem from Real street he help me out as I had a big order with him $17 each .
 
how am i meant to work out what I need though? the block isnt the same as my crank and im using aftermarket rods so colour codes are useless? :/
 
Well I was going to go oem, until I read how much they cost! May get a set of ACL and measure the clearances to make sure I'm happy with them. Risk that they aren't all acceptable but will work out cheaper if they are.
Plenty of builds throwing ACL bearings in and running sweet so...

ditto, I have absolutely no idea how to work out what I need. I've been told that I need all 'standard size' from machine shop.
There doesnt seem to be any way of working out what I need based on a 'standard size' crank, so I might just go ACL, get them to check the clearances with them. Then if they're way off, I can just order the odd oem honda one to go in place I guess. Cant see the issue with mix and matching if need be for the price of ACL, especially from america?
 
I believe most manufactures standard size is one size, honda as you know aren't.
I believe my b16b was all green except from one was brown.
To measure you can either use plasti gauge on an existing bearing and work the clearance out from that, or use a dial bore gauge and micrometer to work out the clearance.

I don't see a problem doing it the way you said, others will say it's a massive no-no though, way I see it is the bearings never contact the crank anyway? Oem are tri-metal as are ACL? Where's the actual difference lol

I would do that, £400 on bearings is retarded.

Oem bearings are made by a company called taiho, you can buy a set of taiho standard bearings for around £50 if you don't want to use acl
You can then just mix and match any that are to tight/loose clearance with bearings from honda
