Thanks for the response CNC-Dude. I think you are correct in saying that the greater challenge will be the turbo install. So the key question might be: Will the turbo be any harder for the 292 over the 250? I will be dealing with the same engine compartment constraints either way, other than the height. If I have to run a pipe or something of significant size over the engine, the 250 would allow more space. Ideally I would not have to run anything of significant size over the engine and the larger tubing could be routed around the engine instead. But it is a bit of an unknown for me at this point. Perhaps I should be asking members that have a turbo installed to post photos of their installation and measure how much higher the components protrude above the engine?
