Vortec 6000-Swapped 996 Porsche 911 Cabriolet Will Upset Purists


Inspired by the longstanding Chevy small-block V8, the LS engine family entered production for the 1997 model year in the fifth-generation Corvette. The all-aluminum lump was followed by a lot of truck-specific motors, including the LQ4 that GM used to market as the Vortec 6000.

More durable than all-aluminum LS powerplants, the sturdy LQ4 was used even on 3500 workhorses. Capable of producing at least 300 horsepower and 360 pound-feet (488 Nm) of torque completely as standard, the 6.0-liter truck engine is extremely popular for engine swaps because it’s very cheap.

Some of those swaps, however, are more special than others. This 2000 model year Porsche 911 Cabriolet stands out thanks to the Renegade Hybrids mount kit and plenty more goodies, including the 5.3-liter cylinder heads, Summit Stage 2 camshaft, Melling high-volume oil pump, Fast 92 intake manifold, and LS3-style throttle body. Are you curious why the owner didn’t replace the original boxer engine with another six-pot boxer?

“The standard M96 is plagued with a lot of issues from the factory. They are expensive to buy even used. They also don’t make much power even modded. A Turbo engine or a GT3 engine would be way more expensive than swapping in an LS. Also, this cammed 6.0-liter makes more power and torque than a stock 996 Turbo. Just made more sense all the way around.”

Offered with 144,100 miles (231,906 kilometers) on the clock and roughly 10,000 miles (16,093 kilometers) on the drivetrain since 2013, the rag-top sports car has been serviced with fresh transmission fluid and engine oil in preparation for the sale. With three days left on Cars & Bids, the German-American build stands at $17,250 after eight bids at the time of writing.

Even though it’s not perfect from a visual standpoint and the interior shows a little wear as well, the truth is that 996s rarely get more reliable than this. And with LS grunt on deck, this Neunelfer should be extremely fun as well.
