I think a single person in good health with the tools and hoist could pull this engine and have it back running in 6 hours.
That is hood off - to - hood on...
You have to remember there is a turbo and oil return lines and a crap load of sensors. You have to worry about pulling every exhaust manifold stud and transferring them to the new engine.
And then you have to worry about actually keeping everything clean and pretty.
It's a pain on the Slingshot to make every pretty as ya go..
