Yes our stroker is the only one in the world with increased displacement. No, its not a ton- but you also have to understand that being an oversquare engine, we're approaching at-limit piston speeds..... especially if someone wants to rev higher than stock redline.
We've been using Ferrea valvetrain as of late- we used Manley when there was nothing available..... then *poof* Ferrea was in the game once we built a few. Funny how that works.
We use Ibeam vs. Hbeam rods. There's a reason. They are stronger, period. Lots of research backs this up.
NASCAR bearings that can take 2 times the PSI load of BMW bearings.
Main studs, because we feel if you're going through the trouble of a fully built engine- you might as well have it fully built.
Closed deck is our newest development, and specific running changes have happened over the 3-4 years we've offered them. No, I don't push them/advertise them as heavily as others- They were a project and I have a BMW shop to run/manage/work on... So I do Punishers as a side gig. IF things got super serious and we were selling 1-2 a month it would justify hiring someone specifically to either free me up to build them (another CPA/accountant/office manager) or hire someone and train them exactly how I want them built.
Seems the N54 market took a nose dive where "the money" is. We've got 20 N54's here in various stages of life that I work on after work and weekends. I've focused on a few S65's currently, Pauter rods/JE pistons are going in them.... and I have 3 S55's broken down getting development done on them right now for the crank hub issue (which is going to be fixed, permanently) and some fueling entertainment.
All in all, things are busy and we like making a quality product. We stand behind our work, and take care of our clients. On the other hand, you can break a bowling ball with a sponge hammer if you tune it wrong/dump tunes from one car to the other/don't know what your doing.....
