Probably....?
Why all the wild speculation about exotic motors that no member will ever even lay eyes on?
The answer to your question (fitment) is determined by 3 factors.
Oil pan shape (to clear the front crossmember), overall height (to clear the low hood), and transmission selection/placement (driveline angle over the front crossmember, determining height clearance at the front.).
Length and width are insignificant, as other factors will be limiting first.
Either way, the picture shows none of these things.
Would it fit? Probably.
It's a 2-liter v4 that isn't very big in any dimension.
It was purpose-built for 24 hours of LeMans and nothing else... If the 210 employees, including 150 engineers, of the Porsche Le Mans team tailored it specifically for this car, I'm sure it would be great.
