Thanks for your input. I would not even have known the difference between warped and otherwise I would have not known the difference.
As for getting a Jersey specialist, I just want to know if there are any special (inherited over time engine problems) such as the 3,000 rpm problem used RX-7s tend to have. Just want to know because I have a friend who is an automotive specialist in his own right, he is working towards becoming a certified mechanic, he just has to finish up his UTI course, he also took and passed an auto repair course at Morris Tech (tech school). I know that does not make him perfect in anyone's own right but it makes him know a thing or two about autos. I just want to know if there is a huge difference in having a SVX specialist there, in contrast to a general one.
He is also aspiring to become a certified Porsche mechanic, so he might as well get to know the works of some kind of Flat 6.
