This shop is building an LS-based V12-engine

700 horsepower, no turbos, 12 cylinders - Need I say more?

2w ago

Chevy's LS small-block V8 engine is a ubiquitous force in the aftermarket community. The winning formula of a small, lightweight, durable engine has garnered the LS accolades in fans, making high-performance V8 power available to anyone who wants it.

But, in case you haven't noticed, big-bore, naturally-aspirated V8s have fallen out of fashion. If you want more power on your BRZ, slap a couple of turbos on there, maybe an intercooler if you were really going for it. The same can be said for most OEMs; in place of more traditional V8s, and V12s we often see smaller, more efficient turbocharged units.

But, despite this, there is now a shop that will build you a turn-key, ready-to-go naturally-aspirated V12. Isn't that wonderful?

Race Cast Engineering freely admits that its V12 is based upon the Chevy small-block V8's basic design, with the bore and stroke dimensions being identical to those found in an LS engine. And because of these similarities, the pistons, rods, and valvetrains are interchangeable with all things LS.

Much like its V8 forebear, the LS-V12 focuses on cost-efficiency, lightness, and durability. Making use of existing LS-engine components in its design does a great deal to drive down cost; in addition, the shop's use of 3D printed molds is not only economical, but it gives customers the choice of either aluminum or cast-iron engine blocks.

Speaking of price, it isn't exactly cheap-but you sure do get a lot for your money.

A bare-bones turn-key 700-horsepower naturally-aspirated V12 is a special thing, and it comes with a special price to match $41,588. But, for just $3,800 extra, Race Cast Engineering will fiddle around with the engine to get it up to 1,000 horsepower!

Now that's more like it.

  • I like v12s, but I wouldn't want one based on the LS. I prefer this: www.buildingthelegend.co.uk/tera-quad-cam . Or, you could just buy a used one out of a BMW or Mercedes.

  • Sorry, This is going to fail miserably. No one is going to pay 10x for extra 4 cylinders. Well I guess some idiots may. I can go out and buy used v12TT engines out of Mercedes,bmw or even Bentley for less. Making 1000hp which is around 850whp isn’t hard from these engines.

    • Interesting! I wasn’t aware so many people were tuning these older V12’s until I looked it up. Spot on with your thoughts.
