Now if you want to get real weird, bear with me for a second: 5S-FZE! Supercharge the 5S for half the cost of a turbo. All of the parts run you a little over $1,500 if you can settle for some interesting chinese brands and it should make for a fun car. Custom brackets will need made but thats a small price to pay for 6 pounds of boost.
Heres a list to products i speced out at about $1500
- FMIC - $165
Necessary! The 5S is prone to detonation

- Aisin SC14 S/C - $400
Clearly necessary, Could use an AMR500 however it pushes such little boost that you would likely lose power or gain none at all.

- Blow Off Valve - $40
Needed to relieve boost when idle and function as a bypass valve (or just turn the switch off since the SC14 has a clutch pulley)
