an inch isn't much to recover, but it's going to require alot of custom work for that measly inch (mounts, axles, possible cutting), not to mention the other custom mods required, like a custom bellhousing plate, and i'm sure there are a few others... making demon's statement of turbo 3L much more attractive....


3.5L bore = 92.5
3.0L bore = 88.9
3.5L bore centers are placed 4mm farther apart than 3.0L

((92.5mm - 88.9mm) * 3 cylinders) + (4mm * 2 cylinders) = 18.8mm
There could be even more room at either end of the block so that number could very well be 22 - 25mm in difference.



With different bore centers, there is not much chance that the the crank could be used as a basis to stroke a 3.0.
