Why go 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, wastegate, 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 its extended tip compressor wheel design. Especially on the EFR Black Series turbo line the compressor map for these is impressive!
