To use level six on the Edge, do you need mods to the motor? Besides a dual disc clutch.
Yup. You'll need a bigger turbo to keep it cool and probably a lift pump at the very least. That's assuming you already have guages.
If you get a bigger turbo and a lift pump upgrade, that should support a Hot Juice only. You should not need any CP3 upgrade with just HOT Juice. I support triple stack and 600hp with stock cp3.
