what is the stock size for the throttle body and mass a sensor on a 95 gt. Also when would you need to get a bigger one. I heard not to go to big on stock heads.
i dont know about mass air, but a stock tb is 60mm on a 95 gt... ill also refer you to the sticky thread vibrant red setup at the top of the posts. As for changing, I wouldn't go higher then a 65 mm tb unless you have a power adder or you redo the heads and intake to allow for more flow. IMO anything large then 65mm on stock heads is in excess.
