# This Sleeper 911 Is Every Porsche Purist’s Nightmare

*Holy crap! Just sold my motor. Guess I'm committed now. It's kinda scary, actually. Oh well. Here we go.*

So reads the twelfth post of [this insane build thread](<https://forums.pelicanparts.com/porsche-engine-conversion-tech-forum/649179-rsr-ls-conversion.html>) on Pelican Parts, which dates back to January 2012. The motor in question is Porsche’s iconic 3.2-liter flat-six; the owner’s forum username is “not\_hans\_stuck.” It’s an apt handle, considering he’s about to perform the ultimate in P-car sacrilege: Tear the air-cooled lump out of an old 911, and replace it with a water-cooled one. And not just any water-cooled engine, either. It’s a Chevy V8. Like, from a Corvette. Pushrods and all.

**Bring a Trailer**

Here we go, indeed.

The finished product technically classifies as a 1986 Porsche Carrera SC, but it's really something else entirely. The body’s converted to RSR spec, dressed in IROC-style livery. Flared fenders, 11-inch rear wheels, big brakes, custom Koni coilover suspension. Then there’s the aforementioned 5.7-liter LS1 small-block. Pulled from a “pro racer’s” C5 ‘Vette, it runs through a 915 transaxle and limited-slip diff. With some custom exhaust work, approximate output sits at 390 horsepower and 400 pound-feet. That’s a massive jump over the original 217 hp. According to the owner, the car’s only 12 pounds heavier than stock.

The car’s now up [for sale on Bring a Trailer.](<https://bringatrailer.com/listing/1986-porsche-911-3/>) The owner says over $50,000 went into the build; at the time of this writing, bidding stands at $19,900. If you’re into the burn-your-idols thing, or just a really big troll, there are five days left on the auction.
