If someone did a top-end rebuild, it's definitely possible. I only use 
US 93 in my Squareback after I did the rebuild because I didn't want to 
take the chance to let it ping. I have no idea what 93 would equate to 
over there (call me stupid -- I didn't know there was a difference 
worldwide in octane rating), but I'd go as high as you can and see if it 
solves the problem.
