TT, a guy at my base ina different squadron whom I am friends with kind of scoffed at me and more or less told me to "have fun" changing hoses constantly. He had owned a Z32TT which I believe may have been modified upto stage 3 (intake exhaust ecu?) and it blew hoses left and right according to him. Of course it was his daily driver and he owned it for many years in southern arizona where it spent every night outside ( i can only assume the big temp change each day and seasonally contributed to this). He said he didnt regret selling it for his Z33 as a result. I have not had this problemas of yet, but my car has never spent a night outside nor has ever been a daily driver, so knock on wood. However if this is a fact of life for DD'd TT's and especially those in "harsher" climates (I hardly think coastal SC qualifies as one) than maybe swapping them all out for new ones might not be such a bad idea, I doubt you will have been the first.
