Big fan of BW turbos and the company itself. Tell me you'll offer a EFR 9180 Twin Scroll with a 1.05 A/R. Someone has to want to do the dyno queen build or you know 9s 1/4 build.

The kit will only be based around the 3 choices indicated in original post. Sorry bud.

I have a 2012 135i DCT that BMS used for a lot of his N55 testing. I also have the 1M body conversion I live about 10 minutes from BMS as well, and am ready to test DCT and the N55. Let me know.

Cool bud. Stay subscribed as we move along here. Eventually we will do a role call and try to make a sound judgment on the best car to work with. I do like that you are close to BMS, and ready to push the platform along knowing that there are some pretty hefty risks involved.

Was hoping to get to the collector work this week. Didn't happen, been slammed. Next week should be good to go and hopefully have the prototype done for that and the turbo side twin scroll flange by end of week.

Seriously can't wait for this to be released! Im already excited!

If that is the design, then I guess it would be possible to fit a bung into the collectors for the n54s O2 sensors...

My guess is that it will work on the x drive models. But will not know for certain until we try it.

We are working on the tooling and process for the manifold mergers at this time. Being that most of this we want to handle via CNC processes, building the tooling to get going initially is a cumbersome one. However, this should help quite a bit when it comes to future build and fabrications and get very repeatable product designs.

Twin Scroll flange is done, may need a little hand massaging to make perfect... but I am happy with it. Now onto the collectors.
