Why go Stage 3 with BigBoost?
– 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.
– Fully custom turbocharger units designed to meet the flow capacity on the BMW N55 engine on the exhaust and intake side. We have tried well over 15 turbine and compressor wheel profiles and designs to determine which will provide the most efficient flow. Our IN-House Gas stand allows us to do so.
– Race Cars running our turbo kit in 6-12 hours of endurance racing with amazing results.
- Customer Assistance via Email
– We provide tuning advice and even do custom maps if required.
– We provide install guides with over 100 pictures of the installation of each and every component on the kit.
– We DO NOT change the engine mount bracket!! You will keep your OEM RH engine mount bracket (RWD ONLY)
– LAST but not least, there’s not a single Chinese part in our turbo system, it’s all proudly made in the USA, and other parts like the turbo imported from South America.
