: Which is faster? LS6 or LS2

10-03-07, 11:23 PM
I know that the C5 zo6 (ls6) is slightly faster than the base C6 (ls2). Some of that is probably due to the Z bieng a little lighter. Is there a noticable performance difference between the ls6 and ls2 CTS-V?

Has anyone on here did any "side by side comparisons?

The LS6 is like having sex.

The LS2 is like having sex in a truck.

The LS6 supercharged is like 60s free love.

When I was test driving, I thought the LS2 was noticeably stronger on the bottom end. The LS6 is a revver...or rather...as much as a revver as an engine of this nature is going to rev. From 4K up the LS6 pulls really hard. Almost apples to oranges except not really...*chuckle* I think it just depends on what your preferences are.

Apples to apples comparison a 06 Z51 C6 Vette IS faster than an 02 C5 ZO6 Vette...... Remember the LS6 is a bascially a lightly mod'd LS1 while the LS2 is significantly heavily Mod'd LS1..... Look to the Corvette for the comparison, and bascially our CTS/V's are simply 4 door Vettes the same logic can be applied.... I personelly would prefer the LS3 to either the LS6 or LS2 with the LS7 being a bit much for a daily driver.

Could it be that ... LS42 uber alles?

The LS2 needed .3 extra litre and an extra 12mm in TB diamater just to match the LS6.

I would bet an LS6 w/ LS2 IM & 90mm TB would take out an LS2.
