Critical Questions Regarding Rb26 Rebuild

[Nameless EJ6]

Hello australians, I come here in need of solid information about my RB26 rebuild.

My concerns are aimed towards the bottom end. Basically, I've dissasembled the entire motor to discover that there is vertical scorings on the cylinder walls.

So, I'd like to upgrade to forged pistons. What I am curious about is whether it is ok to only upgrade in this aspect without tending to the entire bottom end rebuild. My bearings and crank look fine to me.

There are builders who say it is critical to have everything practically perfectly ballanced and spec'd, but this is not a full out race project. Goal is 500 whp weekend driven.

Any help is appreciated! thanks.

with the engine apart u would be crazy to not change the bearings (500rwhp i'd be changing other stuff too).

trying to do it cheap always ends up costing you twice as much in the end!

Have to agree with CruiseLiner as well. Bearings are cheap, I know everything adds up but while its apart, freshen her up. You'll regret not doing it when you had the chance.
