I have a 93 tt rx7. Maztech is great and Jeff is the man. Just don't take it to Mazsport in St. Pete. They suck big time!!!!!! Had my car for over year after the second rebuild. Said the first rebuild was warranteed for a year, then when it blew up because they didn't change the radiator cap on the first time, they kept the car for more than a year and then told me it was out of warranty and wanted me to pay for another rebuild. I already had spent more than $15,000 with them. Beware, Scott is a con artist!!!
