Ls Swap
#3
Seriously, do an AMG 55 swap... Cheaper in the long run.... I know there's millions of cheap mods for LS engines, but seriously, how much horsepower can you really use, I hang with C6 vettes on the freeway easily.... My buddy has a 2011 Mustang GT 5.0, just called me and said he was dead even with a clk 55 today... He won't run me for that reason.

I think an ls3/t56 swap would be a great combo in the 208. Getting the motor installed and running would be straight forward, but I don't know how you would ever get the rest of the cars systems to work correctly. You would likely loose abs/esp/bas functions.
