About 2 years ago I had to replace the motor in my 1990 MX-6 GT. On a long trip my turbo seized and warped the head. I decided to hunt around for a new motor. I was able to find a guy who imported used motors from Japan who had a 1988 2.2 turbo. Much to my surprise the new motor was actually faster than the original, much faster. When I drop the hammer now I really have to hold on to control the boost. Does anybody have some inside info about this. Did Mazda tone it down a bit in the 1990 model year. Thanks.
