Hi All,

I have a 1990 r32 gtst with the nice rb20det. Now i was searching on the internet to find a nice metal headgasket. There's only one with i don't know and that the bore of the engine. All i can find that is 78,0mm. But all the headgaskets are 80.5mm or 83,5mm. Can anyone tell me which one i need?

Cheers Patrick.
