Aftermarket tuner stuffs a 400hp V8 into a Subaru BRZ, now you can too

For a long time, we’ve seen American V8 swaps into non-American cars as a bit of a disaster. We’ve seen Chevy 350s stuffed under the hood of all sorts of cars that were already perfectly cool from the factory. Yes, they may have tons more power but often the swap makes a mockery of the engineering (and handling) that went into the vehicle’s design in the first place.

That said, meet the BRZ06 from Weapons Grade Performance. The aftermarket tuners started with a Subaru BRZ and bolted a General Motors LS2 V8 from GTO a under the hood. Surprisingly, the removal of the factory 200 horsepower boxer four-cylinder left more than enough for the 400 horsepower 6.0-liter V8.

“Other than mocking up our own motor mounts, transmission mounts, and oil pan, the swap was fairly straightforward,” admitted shop owner Doug Ross. The only thing the shop wasn’t able to figure out was the electronic power steering or the tachometer.

Subaru was very proud if its near 50:50 front-to-rear weight distribution. The guys at Weapons Grade Performance claim that the LS only adds around 80 pounds of additional weight in the front end, so the handling isn’t too wildly compromised from the doubling of horsepower.

Have a BRZ? Want to double the horsepower and nullify your warranty? For $3,000, you can get the basic swap package, including motor mounts, transmission mounts, driveshaft, oil pan, and clutch master cylinder. For $9,000, though, you can get the full package, which includes “all of the above, plus an exhaust system, cooling system, wiring harness, and everything else you need except for the actual engine and transmission,” according to LSXTV.

We like the idea and we appreciate that the Weapons Grade guys had the gall to go through with the swap. But it’s still a bit Mickey Mouse for our taste. No tach? Really? C’mon.

Had they swapped the Suby boxer for a Lexus IS-F V8 and gotten all the bits working again, they’d really have our attention. For now, though, they’ve got an imperfect – albeit clever – answer to a question that few people were asking.

A new sodium battery posts wild four-minute charging numbers, but don’t expect it in an EV yet
The breakthrough could improve fast charging and battery life, but the study hasn’t demonstrated those results in a production-sized pack
EV Charger

A new sodium-metal battery has posted a charging number that makes today’s EVs look painfully slow. In laboratory testing, the cell operated at a 15C rate, equivalent to completing a charge or discharge in roughly four minutes.

That doesn’t mean researchers plugged in an electric car and watched it fill up before the driver finished buying coffee. The result came from a small experimental cell using a new quasi-solid electrolyte, while the larger pouch-cell prototype delivered far less dramatic performance.

The Apple Car may be dead, but it became the foundation of Apple Intelligence
A decade of work on a canceled car project reportedly laid the groundwork for Apple Intelligence.
Apple Intelligence in Apple Car

The Apple Car may have never left the garage, but it apparently gave birth to Apple's AI ambitions. According to Bloomberg's Mark Gurman, Apple's canceled autonomous vehicle project, one that consumed more than a decade of work and over $10 billion before being scrapped in 2024, ended up laying the technological foundation for Apple Intelligence. In a rather ironic twist, one of Apple's most expensive failures may also become one of its most important long-term investments.

The Apple Car forced Apple to think like an AI company

Volkswagen’s ID. Unyx 09 just leaked, and it’s the kind of EV I want to see in the US
VW's partnership with Xpeng is producing exactly what we hoped.
Bumper, Transportation, Vehicle

I've been watching Volkswagen's China lineup quietly get cooler for the past two years, but the ID. Unyx 09 might be the moment it finally gets exciting, not just for Chinese buyers, but for the rest of the world as well. 

Regulatory filings from China's Ministry of Industry and Information Technology, Batch 409, have exposed the full specs of the upcoming sedan ahead of its official launch later this year, and it looks nothing like any VW car I've seen before (via CarNewsChina).
