Just so no wondering... The pictures will get better, already have a lot more, but trying to get posts up so I can paste direct pictures instead of links... I am not building the M42, just pulled the original running fine still at 240,000 miles... I purchased a M42B18 out of a 1993 BMW with only 93,000 miles on it(it was a salvage yard buy). I hope to boost starting 4-6 psi safely for a start. I have what seems to be a growing purchase list of parts that I will post pictures of later... My turbo stuff is mostly God Speed, and AEM, and I have new flow tested 660cc injectors with a 255 fuel pump. I am new to this type of modification, a huge step forward after plenty of engine, and transmission swaps, along with bolt on mods to many kinds of used older vehicles...
