The name "ZL1" carries a lot of weight around the GM history books, so the 2013 Chevrolet Camaro ZL1 needed to stand up and earn its badge the right way. Fortunately, GM delivered in a big way, starting with a 580 horsepower LSA V8 borrowed from the wonderful Cadillac CTS-V, plus the suspension and brakes from a Corvette ZR1 to put it to good use. However, even those impressive attributes weren't enough for the former owner of this BEAST, so he brought it to the pros at Advanced Modern Performance along with an open checkbook and told them to go buck wild. Aside from the body, not much was left stock, and we'll do our best to cover all the major upgrades below, including what it took to get a Dyno reading of a whopping 1170HP (that's not a misprint). But if you take anything away from this ad (and please call us to get the full scoop), please know that this 2013 Camaro ZL1 Twin Turbo is the meanest, fastest, downright SCARRIEST muscle car in our inventory. This 2013 ZL1 was Chevy's take-no-prisoners Camaro, and it was essentially impressive on every single level. Born to be hammered at the track, this 17K-mile beauty seems to have bucked its roots and instead lived an easy life in Oklahoma and Texas, where it spent the majority of its life driving on sunny days to car shows. As a result, it looks virtually new, with hardly a mark on the gleaming Summit White bodywork, short of a couple miniscule rock chips up front and a micro-spec or two on the chin spoiler that were acquired over the years. The ZL1 looks like no other Camaro designed before it, with a functional air-extractor hood that looks like it was borrowed from the set of the most recent 'Transformers' movie, a deep chin spoiler, side skirts, a rear ducktail spoiler, a simple lower diffuser with integrated exhaust cut-outs, and a few other aero tweaks designed to make its factory-rated 180+ MPH top speed a little less harrowing. And don't worry, even with all this car's extreme upgrades under the skin and its 1K+ horsepower rating, that gorgeous stock bodywork will still hold together as you bend space and time whilst blowing past 200MPH. Exceptionally clean, we can find very few nits to pick on what is obviously a very well-kept performance car, and other than those killer Forgeline 20-inch wheels stuffed inside the wheel wells, it looks like a bone-stock ZL1 on the outside. Much like the exterior, the interior mostly resembles the factory ZL1 set-up, although after a second or two inside you'll quickly be acquainted with this cabin's upgrades. The ZL1 interior was purposely designed by GM for more power and speed, starting with deeply bolstered leather power buckets with suede inserts that grab you like Velcro. ZL1 embroidery makes this one stand out, just in case nobody noticed the bodywork, the badges, or the exhaust note, and there's a seriously beefy steering wheel with proper thumb notches at 10 and 2. Suede accents on the dash and red stitching throughout lends it a racy look, too, and you'll note there are throwback design cues everywhere, including auxiliary gauges down on the center console. Of course, it's still plenty comfortable to drive and everything was standard on Chevy's top-of-the-line F-body, including A/C, cruise control, power windows, locks, seats, and mirrors, and an impressive Boston Premium Audio touchscreen stereo with navigation and a back-up camera. No, you won't feel like this is some bare-bones race car, although there's lot of race-grade stuff too, starting with the beefy, welded-in 6-point roll cage that includes removable door bars, aftermarket gauges integrated into the A-pillar, 5-point racing harnesses, an AFX air/fuel module mounted to the center console, and a hidden Passport Laser Radar system. The back seat has been rendered useless by the roll cage, so its frame was deleted to shed weight, and the custom ZL1 floormats and trunkmat from Lloyds finish off the cabin perfectly. We'll start by telling you that this thing is flat-out SCARY to drive if you don't know what you're doing, so take caution – this is a serious car. Built capable of producing 1600+HP to the wheels, it sits with slightly less boost (21 PSI) and a mild tune yet still laid down 1170HP on the Dyno. It's a handful, but rather than competing in the ½ mile and dominating roll racing, this beauty has been used as a street car instead. At its heart is a Late Model Engines aluminum 427 ZL1 6-bolt O-ringed long-block rated up to 2000HP, complete with a billet crankshaft inside and a Twin Precision Ball Bearing 6466 twin-turbo set-up linked via a custom-tigged V-band system. The thirsty engine is fed through a Fore Innovations triple-pump fuel system and has even been flex-fuel tuned to take E85 gas as a primary fuel source, 93 octane as a backup. A Tremec Level 7 RPM 6-speed gearbox handles all the power with relative ease via an RPS billet carbon quad-disc clutch, spinning a carbon fiber driveshaft linked to the Hendrix Engineering full 9" IRS differential and axle kit out back. Giant sway bars, 1800HP-spec Fatty Axles, and upgraded shocks/springs keep this beast planted to the road, while giant Brembo 4-wheel disc brakes stop it all on a dime. A fully-tigged Magnaflow X-pipe exhaust runs from the engine to the tips and sounds downright pornographic to anyone with a pulse, and the rolling stock rides on Forgeline ZX35 3-piece forged wheels wrapped in 295/35/20 front and 315/35/20 rear Michelin Pilot Cup sticky radials. Words can barely describe the power, performance, and pretty looks of this built ZL1 Twin Turbo but call us and we'll do our best to espouse its many virtues. Call today!
