What Automotive Project Would Be Your Dream To Complete?

We all have dream project cars, the things we'd love to spend our days working on rather than fixing the shitboxes we already own. Why work on the real broken car in front of you when you can dream up a cooler car that's broken in more interesting, easier-to-fix ways? Sure, you may be stuck with an Impala that needs its brakes bled, but in your wildest dreams you could have a WRX with a shiny new set of Cadillac calipers — which, unfortunately, also need to be bled. 

Today, we're talking about your dream automotive projects. Not the cars you want to do them on — we get it, we all want an old air-cooled Porsche or a Toyota 2000GT — but what you actually want to do to those cars. Throw some extra boost at an FD RX-7? K-swap a Subaru BRZ? Today, we're talking about the actual greasy-knuckle jobs you'd like to do. 

I've long wanted to pull the L-series out of an old Datsun Z and replace it with a modern RB26, but in recent years my tastes have matured a bit. Rather than a full engine swap, I'd rather add some more period-correct forced induction to that L-series — maybe by borrowing parts from the 280ZX. Sure, the RB would be better, but I imagine a turbocharged L-series would be such an interesting engine to actually drive. 

I'd turbocharge an old Z, but what would your dream automotive project be? Do you want to kit out an XJ for Dakar, or build a first-gen Miata for autocross? Let me know down in the comments, and I'll collect my favorite answers later in the week. Bonus points if your pick is a project or mod I've truly never heard of — I always love finding new corners of the automotive world.
