I'm about to buy parts to start on my 2.3 build. I will be using

manley turbo tuff 150mm rods
manley 100mm forged non billet crankshaft
wiseco 1400 hd 9.1 85.5 pistons


what about the main and rods bearings. which brand should I go with?

 

Acl

 

acl race

 

You can also go with Cosworth however ACL makes the bearings for them

 

on maperformance.com there is an option to coat the acl rod and main bearings
does anything do this and is it worth it?

 

Definitely acl race I opted out of the coating although im not sure of the benefits.

 

My thought on bearing coatings is that if it is applied over the bearing's break in coating it will be washed away within seconds of the engine firing up. Makes sense to me on the pistons, just not on the bearings..

 

I was skeptical when dry film bearing coatings first came onto the scene, but not any longer. They function as advertised, that much now having been demonstrated beyond debate. How much value they carry in this type of application is a matter of discussion, but quite a few top-tier professional racing programs are using them.

 

I went with the ACL race bearings in my build.

 

A few people including me are opting for the new king xp bearings. I have a thread at the top asking what other people thought about them. And nothing but good things from these bearings. Also very VERY consistent on there clearance unlike acl. They guarantee within .003 on all rod bearings witch is great! Check em out
