o.k
Can I just confirm one thing.
A r32 silvertop rb20det stock turbo will fit on my r31 red top rb20det.
No mods required.
actuator,banjo bolts , water and oil lines all match up.
no tune required
dump pipe same, elbow same etc
Remember i am not after performance gains here.
Car is to remain stock.
After all any turbo would perform better than the stock red top unit.
