E85 if you have access. If not you will want to get a Methanol setup to run with pump gas.

Safer Options to add but not required:

1 step colder plugs gaped around 0.018
GFB DV+ to keep boost longer as stock diverter bleeds sometimes.
FTP Intercooler pipes as stock break sometimes
LPFP stage 2 fuel it kit
Bigger Turbo: Stage 2 Pure, Hexon Stage 2, or do Custom big turbo.
Also factor in if you run e85 you will shortly need to replace your fuel filter and injectors as it has high detergents and will more than likely clog those items as it cleans your gas tank and lines etc.


So this should get you there if not close. Might not be the safest option as the turbo is taxed cause it's so small and its peaky. Safest bet would be to go bigger turbo as it helps free up some air and also will be a lot safer for the motor by moving the power band to the upper RPM range which will prevent the rods from stress!
Also intake and exhaust add close to nothing but sound.
Yeah,I learned about the turbo for sure haha. Pushed it at 23 and seals started to give after 15k miles. Just slapped a new one in.
