Why going 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 endurance racing with amazing results.
Best customer support in the industry, any time you can hit me up on text, FB, IG, WhatsApp, email, etc whatever works best for you youll see a less than 10 min response time from me or any person on the BigBoost Team.
We provide tuning advices and even do custom maps if required.
We DO NOT relocate the water pump, you keep it in the stock position, not even required to remove it to install the turbo kit.
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)
Boost Control managed with the stock EWG system
LAST but not Least, theres not a single Chinese part in our turbo system, its all proudly made in the USA and other few parts like the turbo imported from South America.
