    • Horsepower Freaks Attention to Detail - MSpired's M3 Diagnosis

      MSpired's M3 came to us a couple weeks ago. He asked us to install our stage 2.5 turbo kit on his M3 and utilize his existing motor from his prior VF stage 3 build. When we (John and ChrisK) disassembled the motor we found that the piston to wall clearance was too high and this was most likely the cause to his excessive oil burning problems. As a result, Mike had to source and ship us a new "used" block, which will be arriving here shortly for us to build.


      Many people have asked how his car is doing, so our techs documented everything they found along the way that will be cleaned up and fixed on assembly. Here's a complete list with pictures. I want to point out that our techs are very anal. In many cases there is nothing wrong with using an incorrect fastener but they make sure that all OEM fasteners go into their intended locations. I also want to point out that we do not know specifically who was responsible for these mistakes but they do exist on his car today and we will be fixing them all.
