The engine has coil-on-plug so the lavender wires must be for something besides plugs. There are some differences I see in the case on this one compared to my Boxster S case, so I think it is built on a 996 but they are very similiar.
That being said, it is not just a matter of plumbing since the engine is too wide, with the coil-on-plug hitting the suspension ear. Ask me how I know
See pic below.
The intercoolers are gonna be way too high also but you would need them in cool air anyway so sticking out of the engine bay may work
It would be crazy tight trying to make all the turbo stuff fit under the car in a 914, but it would be FUN. Maybe a single turbo with a water to air intercooler
Thanks for posting the pic, that is not something you don't see everyday......unless you have $175k
