Just following up this topic for anyone that is interested....I was talking to peter hall who used to work for willall and now works at a shop i frequent to buy parts. Anyway he recommended the ATI balancer over the Ross, and said that the 26 std balancers are usually shagged by now.
Also recommends the performance metalcraft sumps. Im going std rods as well now with just some arp bolts (only 100 bucks), main and head studs, acl gasket kit, acl race series bearings, ATI balancer, performance metalcraft sump, reusing my pistons and N1 oil pump etc.
Another thing he said that most people over look was a front LSD, he says if u have to not spend money somewhere else on the car to get this its well worth the money and really transforms the car, im going to look into it. He recommended ATS over OS giken as ats is direct kit, OS you need to machine the sump for it to fit in.
