I didn't say you didn't know what you are doing. I am simplying saying that amoung the cars out there, this will be one of the toughest to do so.
My comment may sound cautious/skeptical because I've researched in depth trying to get into the MSS52 ECM and anyone who knows anything isn't willing to reveal anything. Furthermore there are only two programs available that can open the programming of the ECM and both are near $15k (WinOLS is one but you need the full version to get anything of use).
I'm not doubting you have the knowledge or the ability to take on and complete such a project. I'm just trying to give you a heads up that it's going to be a "beast" of a project, pun intended.
I am no expert, but the computer side of the equation has been done for forced induction (supercharging) on the S62 motor. While turbocharging has some different characteristics (immediate SC spool up vs. turbo lag for example), I wouldn't think the differences are so big that the computer program for SC wouldn't be a good base line. My point is that getting into the computer for forced induction has been done.
Packaging will certainly be trickier. Turbos like being near the EM and the closer the better to curb dreaded lag. Heat is also an issue, but I suspect not as big of one as fitting the turbos. Option of two small turbos on a V8 gives a little more flexibility. But it will still be interesting.
Hey, don't discourage the guy, let's hope he can make it happen!:cheers:
