I have a 99 Lexus gs400 with 211k miles and weapon-r air intake. I want to boost it either supercharger or turbocharger but I need help making a plan for it and what to get. My dad and I would be installing it since he owned a 98 and he did smaller upgrades. It’s definitely going to be a project so I’m wishing on y’all for help. Money won’t really be an option since I’m getting a job that pays well while I’m at college. Next year would probably be when I would want it built if I could.
