hello everyone, i'm looking for crank bearings to replace the original ones that got damaged due to dirt in the oil. as per my mechanic i have to upgrade it to size 10. i tried ACL performance bearings, but all i see is 4g63 listed. anyone can help?

thanks

 

Calico and cosworth

 

I've just ordered cosworth mains and rod bearings

 

thanks guys, ill check them right now, i need them asap

 

ACL are readily available, just not in catalog yet.

 

Mitsubishi 4B11T Evo X 2.0L
Rod Bearings Main Bearings Thrust Washers
4B1236H Std,.025,.25 5M1237H Std,.025,.25 1T1237 Std
4B1236HX Std 5M1237HX Std

*
H = Standard oil clearance
HX = +0.001" extra oil clearance

 

I was recently in the same search as you and these are the part #'s straight from ACL. They dont have them listed on their site but there available for sure, I just actually received my set not too long ago.

 

I would go with Cosworth, they have just been known to work with our motors.

 

^ majority of aftermarket bearings are ACL re-stamped to their own. Wouldn't be surprised if Cosworth did the same. Same goes for Cometic headgaskets. They produce pretty much every kind of multilayer rolled headgasket for every application and many places restamp it.
