Figured DIY section is the best place to put this post since it will be very
Do. It. Yourself…
As the title title states I’ll be putting a turbo s52 that I had in my old e36 into an e91 328i and then mating a 2014 M4 Gen2 DCT to it as well.
The overall goal is to LEARN with this project. Everything from building custom engine/transmission mounts to custom wiring and learning about CANbus as well as how to throw bondo and paint on a car. I’ll use this post as a reference and guide for people in the future who are or doing something similar or might run into issues that I know I’ll encounter!
Iv done ALOT of pre-planning (famous last words) I have a google doc that’s about 3 pages long now with information and other resources for me to reference and how I want to do this whole swap. It’s going to be a long project but I hope to keep this thread updated as best I can as I progress so bear with me if there is nothing new happening everyday. I’m gonna do my best to document and photograph everything as I go along and upload it.
So to the meat and potatoes; I have split it all up into phases.
