Why going Stage 3 with BigBoost?

– 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 you’ll 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)
– 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 few parts imported from South America.
