I'm currently in the process of refreshing my turbo lump before I drop it in and have come to the point of putting in new big end bearings. I was going to just order Toyota standard replacements (std-no.2) but should I just get ACL bearings instead??
I'm inclined to go for oem bearings but so many people use ACL bearings on big builds that its made me wonder if oem is worth 3X the cost ?

I know Pete is using acl race bearings on my build so must be OK.

That's my thinking when I see respected builders like Pete using them, why should I not, would be good to hear his thoughts.
my only concern is the oil clearance as for all of my searching they only appear to be one size yet the toyo ones are 3 sizes, that said the difference in size is minute and mine are slap bang in the middle of tolerance so if ACL is equivalent to size 2 they would be perfect.
I might ping Pete a message but I don't want to hassle the guy, he must be inundated with questions like this

just looked up the spec sheet of the ACL bearing, its a damn sight more informative than sellers listings. Their standard size has a wall thickness of 1.488mm which puts it on the boarder of size 1/2.
I think I'll give that a go and see what it comes out on the plastigauge

People use them as they're cheaper, but nothing wrong with ACL or Clevite
If your old bearings were ok, I would think std size should be fine but deffo plastigauge
I would also swap out the thrust bearings.
