Essentially every car manufacturer out there is now pushing 2-Litre turbo fours as either their primary engine, or a desirable upgrade. BMW sells $60 thousand sedans powered by a Turbo-4, as does Cadillac.
Architecturally, they are all basically the same. 4-in-line, DOHC, fuel injected, etc. Power ratings range from 200 to well over 300HP. It is the base engine in the Volvo XC90, for goodness sake.
In a Buick, GM rates their Turbo-4 at 250HP, but in a Camaro, the same engine is rated at 335HP. In Cadillacs, it's rated between 270 and 280.
What is the difference in these engines? Is it just the programming of the engine control module?
Why couldn't someone replace the chip in their Buick and have 335 HP?
Anyone know the answer?
