      Great video. Kudos to the builders.

      Anyone else notice the garage shots have the L/R audio channel swapped?!

                    That cowboy rework on the hood inner killed it for me. That is faaar from ”OEM +” in my book.

                      Look... the hood fits and everything

                      Unlike Brintech's 1M S65 build, this car is very Frankenstein IMO.

                      If I am correct in saying that the factory DME and all other electronics would work seamlessly in an E92 chassis, I'd rather see the S85 in a E92 M3.

                        I'm guessing that isn't final fit as here are some screenshots of other v10s they've done. Also common sense tells me that the owner, who has spent a boat load of money on this car, isn't going for that. Don't be a hater.

                          You'd think that they would have done final fit as they already cut out the internal bracing on the hood. I also question how reliable this will be long term with the aftermarket ECU running such a complex engine. I've seen quite a few projects like this where they end up parked in the corner of some garage after something ends up not being reliable.

                            I thought ECU Master black was the go to?

                              Hat to say it but would love to do an E90 with the V10 and DCT! I hate to say it because thats my wallet talking......LOL
