Testing and tuning underway for this monster. The manifold is an equal length twin scroll tube style kit. Currently running a water cooled 67mm garret turbo. There is no words to describe the exhaust note of this s55. Many people hear it and think it’s a v10 lambo. Gone are the days of the horrible sounding s55. I am posting this to get a feeler on how many people would be interested in purchasing this kit. Of course this is just a teaser shot of the engine bay and I will have full pics of manifold design including logs, dyno numbers and price lists posted in about a month. It’s already making 580hp on stock boost levels 18-19 psi according to the I drive display.

This is cool. I do recall a N54 bottom mount that never seemed to get fully released or marketed though.
The n54 kits was a huge learning curve. This will be much different. I did end up selling over 10 kits and I learned being a business owner and fabricator all in 1 was too much I could not keep up. This will be layed out differently.
