I purchased an N55 G600 package in July of last year and provided a review at 250km.

Since installed, I have put 10,000km on the new engine and my experience has been amazing. Running as well as it did on day one. The engine has given me no issues whatsoever through my time of ownership and I couldn’t be happier with the results.

Thank you Ghassan Automotive!

Last year, the motor in my 335xi breathed its last, and I was forced to find an alternative. After months of searching, I finally settled on Ghassan's N54 g800.

Ghassan sent it out to my shop in CT and it was installed. Following the break-in period, I finally had the chance to see what it could do. I was blown away. My car has never run this well, ever. Even though I get my work done at a BMW-specific shop, they are still amazed by the build we've created.

Ghassan is using this motor to set records left and right, and I feel honored to have this same motor breathing new life into my car. I've had nothing but a positive experience with their customer service, and he personally replies to messages with any questions I have in the evolution of this build.

Thank you, and I'll be hitting you guys up soon for the TH400 :)
