What's an FRR?
:agree:Affectionally the '99 were called FRC's for Fixed Roof Coupe. There are a few expensive ways to get the Z power. Some are not practical. Get a new (or used) one. NOT PRACTICAL. Change the head/cam/intake off the Z. feasible if you can find a Z owner that is upgrading. Or, if you are going to the trouble of swapping the H/C/I route get on with more potential than the Z and instead of goign from 345hp to 405 hp, you can go from 345 to 445+. Add some long tube headers and a cat-back and a tune and you will really wake that monster up
