What aftermarket parts should a get for my mustang gt 2000?
If aiming for that low boost why not slap a supercharger on it?
For injectors I'd use 42#ers and pick up a vortech T-rex in line pump and maybe a Kenne Belle boost-a-pump and kenne Belle boost a spark Probe fully forged pistons and rods and some Xe262h cams and a stage 1 or 2 Fox Lake port and polish job of heads. Be sure to get the car tuned so you can get the bugs out. Id also recommend that if hitting over 500Hp to invest in a good aftermarket block cause it will be in danger of splitting
