I started a turbo build up on my 91 E30 using a M50 Turbo manifold with runners 5 and 6 chopped off and blocked. Fits the M42 like a champ and bolts right up but I am running into trouble fitting the turbo. If I bottom mount it I need to replace the engine mount on the passenger side with something custom and if i top mount it I need to use 4" of spacers so the flanges can mate up. Just wondering if anyone here has used a M50 turbo manifold on an M42 and how they went about fitting a turbo. Turbo is a 63 on the hot side and a 60 on the cold. USing a 6psi wastegate, fmu, 2.5" turbo back and a nice meaty intercooler up front. Hopefully I will be able to get the help I need here to finish this up over the next few weeks.
