Usage & Important Information

• This engine is designed as a high performance, race-oriented package and is not intended for high kilometre daily driving or extended low-load cruising.

• Due to the nature of high output engines, service intervals and rebuild requirements will be significantly shorter than a standard or mildly modified street engine.

• This product is best suited for track use, motorsport applications, or controlled environments. Any road use is at the customer’s discretion and responsibility.

• Professional installation, calibration and setup are required. Incorrect installation or tuning may result in engine damage.

• Operation of a vehicle at this performance level requires a high level of mechanical understanding and driver competency. Boosted Engineering accepts no responsibility for damage resulting from misuse, improper operation, or use beyond the intended application.

• All performance figures are indicative only and dependent on supporting modifications, fuel quality, and tuning.

• By purchasing this product, the customer acknowledges the intended use case and associated risks of high performance engine operation.
