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.

– GTX turbos provide excellent reliability, and are quick to spool up! They are the perfect balance between size and flow that when paired to the correct exhaust manifold allow for high top end power without sacrificing spool time!
