Installing An LS3 V8 Is The Extreme Way To Make A BRZ Faster

If you really can't cope with the Subaru BRZ's lack of firepower, allow us to present a drastic solution...

We get it: the Subaru BRZ/Toyota GT86 twins are not that powerful. Neither company wants to increase the output of its version, so if you want to extract more from that 2.0-litre, naturally-aspirated flat-four, you’ll need to think about adding a turbo or supercharger into the mix.

Or you could do something much more drastic, not to mention more expensive: dump in a whole new engine. In the case of this Brill Street Motorsport BRZ, that ‘whole new engine’ is an LS3 V8 pumping out 580bhp. Should do.

The car was filmed by YouTube channel Automotive Mike recently (above video), but it’s been doing the rounds for a while now. That means there is an older video out there that gives us a look under the bonnet (below) if you can cope with the dreadful jerky, vertically-shot footage. The LS3 looks quite snug in there, doesn’t it?

Installing it required a whole new front subframe, and the engine sits on Corvette ZR1 mounts, Speed Hunters reported a while back. Apparently, the combined weight of the V8 and its Tremec gearbox is only 20kg more than the original engine and transmission. Not bad.

The finishing touch? That’d be a Rocket Bunny widebody kit. Well, the exhaust note isn’t subtle, so it needs to look quite excessive too, doesn’t it?

Only 20kg more? At least the weightdistribution stays great that way!

why does it have to be a LS?
Why not the EZ36 H6 with a hint of Forced Induction? That would be a nice Challange and something very different.

LS is low buck power. There’s a million parts, relatively cheap, easy to work on, reliable and it fits nicely. That’s why.

Good ‘ole LS, always solving the power deficits of popular cars since 1997.

EZ30 is an amazing engine but I don’t know if a flat 6 would actually fit in the BRZ.

The BRZ is becoming the front-engine Porsche 914. I like that. I can’t wait to see all of the swaps people come up with for these things.
