I searched to the ends of the internet and I can't come up with an answer so I hope someone knows this. My block and head are ready to be picked up from the machine shop in the morning and I am confused on my bearings.

When this started, I was rebuilding my B16 turbo motor so I ordered ACL standard size bearings as a starting point. Well that went way out of control and now I don't even have the same block, car, turbo, anything. It's now an all motor hatch and I can barely even remember where this started two months ago.

Either way, I bought standards with the intention of measuring off them and IF something was out of spec, just ordering the couple I needed in different sizes and having the others as spares. Now with the B18A going back in instead of the B16a, are the crank and rod journals the same size? ACL's website sucks, I even searched Ebay hoping to find a close up pic of the box to see if the part numbers are the same and I can't tell. Hope you guys can help because assembly starts this Friday and I already will need to order a headgasket once I assemble it to see the thickness I need for proper quench so I don't want to be waiting on anything else when the time comes. Thanks.

 

Edit: do you have the box? does it say on the box what engine(s) they are compatible with?

 

You should be fine. The B16 bearing has approx. .0002 more cl. than the LS

 

Thanks guys, RHT, I have the box and I have the part numbers off of it but the engines are smudged from me handling the boxes with dirty hands while in the shop.

Don, that's good to know, I just want to be close enough that I can at least use them to get clearances off of to order the right bearings in case these are off. But if they were way off, I would be starting at ground zero with an entire new set and I didn't feel like buying 3 times to get it right.
