Porsche 911 GT3 Gets V8 Engine Swap

Someone has swapped a Porsche 911 GT3’s 3.6 litre flat six for a 6.2 litre LS3 V8

Porsche 911 V8 engine swaps aren’t a new thing. However, donor cars are generally a little old, and in need a bit of a TLC.

Interestingly, a 2007 997 Porsche 911 GT3 has cropped on Las Vegas Craigslist, and the 3.6 litre flat six has been swapped for a 6.2 litre LS3 Chevrolet V8, the sort you’d find in the current Holden Commodore SSV.

The engine produces 525 horsepower, and 485 lb.-ft – or 391kW and a face squashing 657Nm if you’re an Australian – and the engine is mated to the original six-speed manual. The owner has swapped the carbon ceramic brakes for steel units, which are better racing as they need to be changed less regularly, thus saving money.

There’s also a roll cage and digital instrument which records race data, in place of the original Porsche set up. Should you wish to drive this monster as your daily driver, you’ll be happy to know that the air conditioning functions as the makers intended, as does the ABS and stability control.

A couple of “LS3” stickers dotted around the car are the only real giveaways to what lies beneath.

Should you wish to purchase this er, “unique” car of the current owner, it’ll set you back $95,000.
