I will be using B16b block with b20b crank & rods, my question is what main bearing and rod bearing should i use? is it the size of the b20b bearings for the main bearings or the b16b size main bearings? I think the rod bearing should i used is for b20b since im using eagle rods for b20b. Also is it the main caps of b16b the same as the B20b? what main caps should i used to the 89mm cranks to be drop off to B16b block?

 

As to what bearings, they have the same main and rods sizes. so just measure and get the correct clearances, I would stick with vtec bearings.

And you use the main caps from the b16b block.

 

Thanks a lot.. :-)

 

main bearings of the b series are all the same. rod bearings will have to be b16a or b20. you can use b18c ones but you'll have to get the rods retanged.

 

Should i go with oem bearings or acl? any recomendations?

 

whatever nets you the right clearances.

 

do you have spec sheet for the main bearing & rod bearing clearances?

 

My motor is that exact same setup as the OP.... Use LS/B20 main and rod bearings...

 

Try to search online for a B18 haynes manual, for the complete detail specs... I got the specs but its on my other pc.... If you have difficulties with the build or specs, PM and I may be able to help you...

 

you've got pm..
