Blasphemous, or brilliant?
Chevrolet's LS7 is among the finest small-block V8 engines ever made, with a racing-derived dry sump lubrication system and lightweight, titanium alloy connecting rods that contributed to its impressive 7,000-rpm redline and awesome volume-specific power output. Who could ever want any more than that?
Apparently, pro BMX rider Abdulla Alhosani doesn't share our enthusiasm for the LS7, as he's just ditched the infectious, high-revving small-block in his Chevrolet Corvette C6 Z06 in favor of something a bit more JDM: a 3.0-liter Toyota 2JZ inline-six like the sort used in the Mk IV Supra.
The work was performed by RSG High Performance Center in Ajman, United Arab Emirates, and although it's shy two cylinders compared to the Corvette Z06's factory LS7, it holds nearly a 200-horsepower advantage thanks to a Precision 6870 turbocharger supplying about 20 psi of boost, and a MoTeC M130 engine control unit. Total output stands at 679 hp on 98 RON - about the equivalent of 93-octane pump gas here in the US.
Just as important as what was gained with the conversion is what was kept the same, the car retaining its original torque tube and six-speed manual transaxle, for superb weight balance between the front and rear axles. Keeping the drivetrain as-is necessitated a custom bellhousing adapter and a custom clutch and flywheel setup, but we'd say it was well worth the effort.
If we had to guess, we'd say purists will be none too pleased with this custom build, but you certainly can't knock it for a lack of originality, and while it lacks the booming, burbly muscle of a big-displacement American V8, the turbocharged Toyota 2JZ sounds fantastic in its own right. And besides, every LS7 that gets removed from a C6 Z06 or a fifth-gen Camaro Z/28 is one more preowned LS7 for the rest of us.
It's a win-win.
