Bet you dont keep it at standard boost for long!!!!! The extra 4-5psi you can run really makes a difference!
Good luck in finding a solid one.I bought my nans one from her.She had it from brand new and it had been sat in a garage for 5 years.My fault as didnt even check it,when i got it home i nearly cried.Every panel had been welded underneath.In the end i had to scrap it and i put all the bits into a solid cabriolet shell.
