This project originally started out as a 2006 325i automatic. At the time no one had done a conversion to a manual. We were the first to break through that barrier and sourced a E90 325i manual to make sure everything would line up and have less of an issue. As Alice sits she has a 335i transmission. This is the transmission we have been using with the turbo installed. Its safe to say it has been holding up to our abuse and the power levels on the street and at the track.
After we did the swap we cut the stock manifold in half and ran the car as a make shift "ITB" application. This with some software tweaking and we revved the car to 8,000 rpms. We did this to help find limitations of the E90 N52 platform. With the turbo installed we don't have plans to rev it 8,000 rpms.
