Coffee Brake: Sacrilegious Engine Swaps

You'll see a few questionable engine swaps on these pages, mostly because they make for good publicity, but also because they often make the car better.  However, some engine swaps are downright taboo -- Chevy in a Ford (and vice versa) will get you dirty looks at car shows and forget about taking a non-Porsche powered Porsche to a PCA club track day.  With that in mind, I'd like to make the topic for today's Coffee Brake: what makes a sacrilegious engine swap?

Let's start with this 1970 Ford Mustang Boss 302 found on ebay with a few hours to go with bidding at $17,500 and just sold for $21,500.  Did I just walk through a wormhole to 1995?  Why is this so cheap?  Oh, the paint is a mediocre quality color change and the engine is a non Boss 302 from a different Ford.  Finding the original Boss 302 is impossible and getting a correct era Boss 302 is going to be expensive, plus the Boss 302 is kinda lame from a performance perspective compared to modern engines. Perfect car for an engine swap.

The logical engine to swap into this thing is this 2012 Coyote 5.0 liter V8 with 6-speed manual transmission offered for $6,499, plus an ECU/harness for another $1,649. The resulting 420 horsepower will be reliable, tractable, and sound perfect with a free flowing exhaust setup...but...it lacks the maniac fringe that keeps me awake at night.


Here is what you need to shove into an unwanted '70 Boss 302.  This is a 2012 3.5 liter Ecoboost V6 from an F150.  It pushes out 365 horsepower and 420 ft-lbs of torque...before you add a chip tuner and intake to boost it to 415 horsepower and 505 ft-lbs of torque.  It may well weight more than the 5.0 Coyote V8 (once you add turbochargers, intercoolers, and all manner of crazy extra parts, but it makes up for this mass in TORQUES.  ALL THE TORQUES.

Anyway, the question is -- is a twin-turbo V6 in a Boss 302 Mustang a sacrilegious swap?  And what is the craziest swap you've ever seen.  Go, discuss amongst yourselves.

  1. I'd like to see a Jaguar V-12 stuffed into a 70s-vintage Camaro.

    1. One of my all time favorite mods is this Jag V-12 stuffed into the nose of Corvair. I suppose the Camaro would be possible, but the Corvair was able to take advantage of the rear mounted transmission.

  3. Every swap is sacred, every swap is great. Cylinder numbers are nothing, and the vaunted reputations of some engines are even less. Anything made electric or that has an electric assist gets 10,000 extra points. I would actually use one of the newer four cylinders or an electric swap to make it really interesting.

    This EV Mustang is the most amazing thing I've seen thus far.

    For those terrified to click, it is possible to fit a 10.2L radial airplane engine into a Goggomobil microcar if your fab skills are spelled with several Zs and EDM-tite, yo.

  5. One of my dream builds is an Alfa GTV with a Ferrari/Maserati F136 R V8 swap.

    This rear mounted Ferrari Nash is pretty wild.

  9. I have a Fiat 850 Spyder with a twin-turbo Subaru motor in it. It's extreme, even ridiculous. But it's hard to call it sacrilegious, because hardly anyone misses these little cars. If done the same thing to, say a 911. Now that'd be sacrilegious (and stupid, given air-cooled Porsche prices nowadays).

  11. A FIAT 600 with a built 427 Ford side-oiler. Saw it just down the street from "Bob's Whittier" (The Bob's Big Boy drive in) in 1966..The place was a mecca for street racers and cruisers back then. At the time I was driving a FIAT 600 sedan with an Abarth 850 Nurburgring Corsa engine and a FIAT Multipla transaxle. I was driving away from Bob's one evening and there was another 600, sporting American mags, parked on the street so I stopped and there it was: all engine. The owner had built a sub-frame and mounted the 427 up front. He was running a four speed that put down the power through a narrowed Ford nine inch rear end. He'd extended the steering column because he was driving it from well aft. He said it was much less hairy to drive than he expected because it just hazed the tires at anything other than the gentlest application of throttle.

  13. To me there are two parts to a bad engine swap. 1) Wrong/ enemy brand of engine choice. Putting an LS1 Chevy into a Mustang may make it go faster for cheap but when you want to sell it the Ford guys wont touch it because of the mass murderer under the hood and the Chevy guys wont touch it because of the metal satan that the beloved LS1 has been put in. The second class of a bad swap is when the result is a worse vehicle than you started with. It often seems like the idea came during a white lightning drinking binge (Hey Cletus! Lets put that thing thar inta that thing over yonder!) The Mercedes diesel into the 1962 Ford Econoline that was featured in DT recently fits into that category. If you make the vehicle better, even if its the wrong engine brand, like the LS1 into Nissan 240sx, Volvo wagon or RX-7 I don't personally have a problem with it....

  14. The disdain of putting a ford engine in a chevy and/or a chevy engine in a ford must be a relative new phenomenon. When I was young there were chevy in fords and fords in chevy all the time, I was always a little curious about the type of persons involved in such swaps…. Maybe the fact I grew up on the outskirts of Hell had something to do with it, I gave up guessing long ago.
    My idea for a few years has been putting a viper engine in a Dodge Little Red Express, with all the attending suspension, brake and transmission upgrades too. But of late with all the 6.1L to 7.2L Hemis out there getting the massive HP and TQ numbers, maybe one of those would be just as exciting…

  15. I think I would like to buy a recent Porsche 911 (1999-2005) with a blown engine, not too hard to find these days with the IMS bearing problem some of them have. I want to install a 3 liter flat 6 Subaru which appears to be much more reliable and make almost as much power. Any comments/suggestions?

    1. It's been done, usually with flat four turbos...but on the NASIOC forums there is your exact build going on, albeit with an older Carrera...a 996 would be much cheaper to buy

  16. This just doesn't seem right... a Harley 1200 cc V-twin replacing the original VW 1200 cc flat-four...
    Is there any redeeming social value in such an act? Or is it just an obscene gesture?

    1. I wonder if that is just trolling - they could have just propped the engine in there for the photo. The car is a split window Beetle (pre 1953) with what looks to be original paint, so it would be incredibly devalued with a Harley swap.

      Not saying it would be terrible - heck it might be pretty rowdy. But in terms of financial value of the car it is like setting cash on fire.

  19. The only sacrilegious engine swap is putting in less power than you take out.

  21. I saw this Ferrari Powered Rambler Wagon on ebay probably ten years ago for $500k. Don't know if it ever sold, but it was rather insane and sacrilegious to many.
