Thanks guys for your quick response,
TR34GT, if you're interested, Barry Stace Automatic Trans Services in Newcastle is a great bloke, and told me that recently, for some unknown reason, the noid kit for the r34 has almost halved in price, he told me last time he did them they were around $700 but now $400. I'm unsure how much labour is involved, however, if I can find a auto-elec that is open this saturday I'll get my alternator checked, if that checks out, I'm getting the noids replaced asap. He can overnight them in no troubles. I'll be sure to let you guys know what happens.
By the by, does anyone know a good source for stage 2 cams for N/A Rb25?
Cheers guys.
