NOTE: As of 1 May 2019 All “Stocker Engines” are currently sold out, and not in stock. The demand for these engines was more than we could meet, and these engines are now only “built to order”, and follow the program that our “Performer” series of engines follow. Due to this, the wait time for a “Stocker Engine” parallels that of a “Performer” series engine.
Stocker engines are built for the car owner that doesn’t have a desire for higher performance, but wants to take advantage of our technology to extend the life of their engine. With no corners cut or details overlooked, Stocker engines simply offer a high-quality alternative and ultimate peace of mind over a factory offered replacement.

The Stocker engines offer factory level of performance with all weak points and issues of the original M96/97 engine addressed, making it much more reliable and long-lasting. The “Stocker” is usually the fastest and most economical route to upgrade or rebuild your daily driver and enjoy your Porsche® again – for years to come. If you desire more power, or track preparation, then look to our “Performer” series of engines.
