The main difference between an LQ4 and an LS2 is an iron block, which means these can hold tons of power. They’re famous for being a cheap way to get insane stats, and this hot Chevelle gained world fame In 2016 from an article at Hot Rod by throwing down 800 horsepower. That’s thanks to 16 psi of boost from a single 80mm Borg Warner turbo. The builder says “getting sideways in third or fourth gear is no problem” we’re not surprised.
One thing that is consistent is the 2.0L V8 engine. On top of having an incredibly small displacement for a V8, the engine features four chain-driven camshafts, a SPICA fuel injection system, 16 spark plugs, and has a rev-limit of 10,000 rpm. The unique powerplant produces 230 hp in the road ready editions and 270 hp in race units. Leave it to Alfa Romeo to find an interesting way to deliver power to the ground.
The CRX Si received Honda’s D16A6 4-cylinder good for 105-108 hp (depending on the year and perhaps tailwind/grade) and 100 lb-ft of torque. If that doesn’t sound like much power to you, well…it’s not. Keep in mind though, that this is still basically a Civic, and that this car only weighs about 2,000 lbs. What sets this car apart from the Civic is not its power, but rather its style.
We have covered a few North American hot cars, but we haven’t covered a North American built supercar. The one that comes to mind immediately is the Ford GT. We say North American built because the car was designed in the U.S., but built in Ontario, Canada.
