Just buy an SRT-6. The Limited engine has a higher compression ratio and mostly different internals in the bottom end, meaning it's going to be harder to get it to take as much boost as an SRT-6 without causing shenanigans.
The SRT-6 engine is built to take boost, comes with a supercharger, and SRT-6es are only $3000-$5000 more than Limiteds now - a steal considering that most decent superchargers are over $1500 alone without any supporting parts.
If your issue is that you want a manual transmission, it *is* possible to mate an SRT-6 to a manual with a different crankshaft and a ton of blood, sweat, and tears (and/or money). HDDP here on the forums has done it, but he replaced the entire engine management system at the same time so he didn't have to deal with angry German electronics. I suspect that Rudy and team at Accelerated Industries might be able to tame the electrical German beast by now (possibly with some help from the Eurocharged crew), but I don't know for sure because I don't think anyone's done it.

Rumor has it the manual also won't take the power of an SRT-6 engine, especially tuned, but since nobody's really tried nobody really knows.
