Rod bearings

Post by foomans2 » Tue May 13, 2003 12:18 pm

Hi,

As part of my S2>RS2 mods I'll be replacing my rod bearings. The early 3B rods were fitted with a single metal shell, unlike the later ABY/ADU which have a three metal variety. I've been recommended to upgrade the shells to the later type and noticed a few owners have opted for a pair of upper shells in each rod. The reason for this is that the uppers are constructed from a harder material than the lowers. Has anyone tried this or could advise me if it's worth it on a 350 -370 bhp upgrade?

Cheers,
Steve. [img]images/graemlins/24430-audibash.gif[/img]
