If the 2.0-liter, 200-horsepower flat four-cylinder engine in the Subaru BRZ and Scion FR-S isn’t enough for you, you’ll probably be a bit more excited by a 400-horsepower 6.0-liter V8 swap. The BRZ’s engine bay, built for the wide flat-four, is big enough to fit the monster LS Series V8.
The LS2 engine in the V8 BRZ originally came from a GTO, but in typical swap fashion, it uses parts from a few different GM vehicles including the CTS-V and G8 in order to fit in the smaller car’s engine bay. The GTO’s LS2 V8 has 400-horsepower and 400 lb-ft torque and the aluminum LS2 only adds about 60-lbs to the BRZ’s curb weight.
The 400-HP V8 swapped Subaru BRZ was built by Weapons Grade Performance in Wallingford, Connecticut. Not just a race car, the BRZ V8 swap still has air conditioning, ABS and the rest of the car’s original electronics excluding the electronic power steering and tachometer.
In case you were worried about BRZ’s performance potential, even with the torque monster V8 swap under the hood the V8 BRZ still uses the factory rear end upgraded with 3.73 gears. Weapons Grade Performance says they can perform this swap on customer cars, so if adding performance parts to your BRZ or even waiting for the 255-hp 2.5-liter 2015 BRZ won’t cut it for you, you should give them a shout.
