After years of R&D we are finally releasing our long awaited 335i/135i single turbo kit.  It is the ulimate turbo kit for your street machine!  They come complete with all nessary hardware to install and is listed below.  We use Precision ball bearing turbos because they are leaders in the industry for offering top performing products that are reilable.  You can choose from your choice of a 5862 up to a 6870 with horsepower ratings from 640hp up to 1100hp (ratings below). 

Included is a T4 twin scroll manifold which is the heart of this turbo kit.  It was put to the test by a handfull of very high performing race cars before fitted to our test car.  With the design it is capable of producing well beyond 1000hp for anyone looking to really push the limits of this platform.  To control all of this, boost is regulated by a pair of Tial MVS wastegates which are mounted down low and out of the way of heat.  Boost is fed to the intercooler by a single 2.5" aluminum charge pipe.  The downpipe is made of 3" stainless tubing in two pieces which is V-Band connected and then splits into a factory location flange.  You will be able to use any aftermarket exhaust system as it is factory fitment.
