Why going with BigBoost Turbo Kits?

– We have done intense and harsh in-house testing, measuring individual cylinder EGTs, and back pressure. With our kit you will see 1.11-1.12:1 Back pressure ratios, these are safe and ideal levels of back pressure for the engine to operate smoothly and safely.

- In this case the EFR is the perfect turbo for those wanting simplicity! No running external boost controllers, wastegates and vacuum lines! EFR turbos are a great combination of fast spooling turbos due to the Gamma Ti turbine wheel material which makes it lightweight and capable of making good top end power due to it's extended tip compressor wheel design. Especially on the EFR Black Series turbo line the compressor map for these is impressive!
