Boost Factory Inc.  has built many RB engines over the years.  They can be found in cars all across North America.  Each engine is built to suit the customer's intended use and purpose - whether it be drifting, drag racing, street, or road racing.  Most of these engines live near the limiter and are making 500+ WHP

All engines are built in-house according to our specification to offer the highest level of reliability as well as power and cost.  It is important to be realistic when speccing your engine, as the tolerances for assembly vary greatly depending on your intended use.  For example; a street engine will be assembled with tighter tolerances than a drift engine.

Every engine is built with the same level of quality, and goes through the same steps.  Your engine will arrive looking new, painted, and properly packaged.
