Then we are talking about different cars. The one i know needed a lot of fabrication around the engine in order to be able to fit a relatively big snail there.

Also, the block is aluminum so it can't handle high pressures well, you'd have to sleeve and reinforce the block with iron.
Turbo's make it harder for the internals. That's true, but AA Level 3 SC pushes ~9 psi to the internal. Now i know that's 9 psi at top end not mid range, but i think 6 psi from turbo would work flawlesly with stock CR. ///Matthew's car will tell us how far the stock internals can go with boost from something other than a centrifugal supercharger.
