Hi all,
I was wondering if any mechanical guru's could help me.
I have been in correspondence with a bloke in NZ whom supposedly has a spec-rar for sale. He has stated there was initial problems with the engine pinging as the car is a japanese import and not used to New Zealand 98 octane petrol. This problem has been rectified by increasing the the head gasket diameter by 0.1mm.
My questions:
1) does what he said makes sense?

2) is he bullshitting me, flogged the car, blown the head gasket and changed it?
3) is there any way to check that the car he has is a spec-c rar using the vin number?

Many thanks. As you realize, I'm not too technically minded but just love the scoobies. I'm off to auckland in Jan so have an opportunity to have a look at the car in person if its worth it.
Cheers in advance.
