I just found one part of the puzzle that I'd need to make this work. SVXtasy has that turbocharged SVX with a 'Y' pipe on it. I sent him an email to see if he could sell me a similar part. If not, I can use the picture to have one made up.
This piece would probably work great. The part of the 'Y' that is a single pipe diameter would be where the maf sensor would connect to. Then the 'Y' would bend and the dual pipes that connect to the throttle body could be attached to this. This 'Y' part is what I'd get a shop to put the three welds in for the vacuum hoses. Three of the vacuum hoses (Two crankcase and one coming off the transmission count as one) could be tide into welds on the 'Y' pipe.
At any rate, yeah, I think this could work. This part needs to be made. I'm sure some exhaust shop nearby can make something like this if SVXtasy isn't selling any of these pieces.
SVXtasy , if you are reading this, this is what we have been talking about via PM.
