Watch a 135i with upgraded turbos easily pull away from a C5 Corvette with a built LS6 V8
Great run here showing an E82 135i with upgraded turbos, full bolt ons, Alpina trans flash software for the 6-speed automatic transmission, meth injection, and a tune from Bren Tuning against a C5 vette with a built LS6 V8. The 135i makes easy work of the C5 from a roll that is stated to have a built motor although what it is putting out is not reavealed. A built LS6 V8 without any forced induction won't have many advantages other than that of longevity over a stock LS6 with the same modifications.
To be noted, this C5 is not a Z06 but is said to have an LS6 V8 which would have to be swapped in. Some controversy on the Vette's mod list and it certainly should be questioned.
