Why would you want to fit that big 6 cylinder in a seven type car if there are better engines available for the task?
The Toyota 3SGTE come to mind and Im fitting a series 2 unit into my ride and if one compare the outputs specs of both engines, the 3SGTE ticks all the blocks.
V6
(new) = 156kw at 5800rpm and 298nm at 4400rpm
3SGTE
(series 2) = 165kw at 6000rpm and 304nm at 3200rpm - std factory 9psi boost.
The 3SGTE makes more torque at much lower rpm and nothing beats that linear delivery of power of this engine.
To top that it is lighter than the V6 and smaller hence easier to install. What it definitely lacks, is the V6 soundtrack but that rush of power only a turbo can deliver is worth much more to me personally.
I hear "tractability" of the V6 in the background but let face it - the 3SGTE is still a 2 liter engine with 8.8 :1 compression ratio without boost and should make decent power with only about 600kg to move around and be decently fast until that CT26 takes over for wicked performance.
