17. Final note: • This turbo kit works with Stock Injector and ECU, boost around 7 psi which is the max boost with stock

setup. With upgraded injector and ECU, you can boost it to around 12 lb, but also make sure your engine is good enough to handle.

• You will need to use 91 octant Gas after adding turbo charger. • Don’t shut off engine after stop, let it run for 1 to 2 minutes so that Turbo can cool down. Or install a

turbo timer.
