Twin Turbo LS ’68 Nova: Turquoise Terror

Kyle Avery says his passion for hot rodding goes back to day one. The Marion, Illinois-based industrial equipment mechanic tells us he was making car noises even before he uttered his first words. โ€œMy grandma used to tell me I was born with it,โ€ he says with a laugh. โ€œIโ€™ve always been into anything with wheels and motors. But one of the first cars that really sticks out in my mind is the โ€™68 Dodge Coronet that my dad had when I was really little. I think I was about 6 or 7 years old when he taught me how to drive it.โ€


With a formative experience like that, itโ€™s no wonder that Averyโ€™s interests naturally gravitated toward vintage muscle cars as he got older. But by the time Avery entered high school in the early โ€˜90s, the mini trucking craze was in full swing, so he decided to jump onboard and give it a try.


โ€œI took some auto body classes at the local college during my senior year of high school,โ€ he says. โ€œMy main project was a Mazda extended-cab pickup I had at the time โ€“ I shaved everything and did all the typical custom tweaks, and I actually ended up getting it featured in Minitruckinโ€™ magazine. But eventually I started to miss the fast stuff โ€“ the four-cylinder in the Mazda just wasnโ€™t cutting it.โ€

That led Avery to acquire a fourth-generation Chevrolet Monte Carlo, which he outfitted with a 355-cube small-block V8 not long after. โ€œI dragged that one out of a field,โ€ he recalls. โ€œIt had an old 267ci V8 in it that was half apart. I just decided to dive in and learn as I went; I really cut my teeth with that one as far as engine swaps go.โ€


Over subsequent years, Avery turned his attention to drag bikes, lowrider trucks, and a Fox-body Mustang build before going all-in with a back-halved โ€™71 Camaro, which he bracket raced at local tracks. Although the car was good for low 6s in the eighth mile, the projectโ€™s racing focus limited how much he could actually use the car, and eventually he decided it was time for something a little more street-friendly.


โ€œBy then I had a kid, and I was ready for something I could comfortably drive on the street; something that I could take the family around in,โ€ he says. โ€œSo I ended up trading the Camaro for this Nova and about three truckloads of parts.โ€

Outfitted with a 327ci small-block V8 and a five-speed transmission when he took possession of it in 2012, Avery says that the Novaโ€™s drag-tuned setup at the time made it a little too high-strung for daily driving duties. He soon set to work with his initial plan of turning it into a pro tourer, swapping out the 327 and five-speed for a 6.0-liter naturally aspirated LS and a 4L80 automatic, respectively, then he dropped the stance with a set of coilovers and bolted up a set of large-diameter wheels. The Nova stayed in this general configuration for a few years, but eventually Avery was ready to turn up the wick once again.


โ€œAround here in Illinois there arenโ€™t very many curvy roads,โ€ he explains. โ€œSo it was hard to stay away from the straight-line acceleration side of performance.โ€

The shift back toward a more drag-tuned combination was also necessitated in part by the addition of forced induction. The revised combination consisted of the aforementioned 6.0-liter LQ4 LS V8, which was outfitted with a Comp Cams camshaft, BTR valve springs, a Sniper throttle body, Bosch injectors, and a Holley Hi-Ram intake, along with a pair of VS Racing 7875 turbochargers.


Fed a steady diet of E85 and running 22 pounds of boost, Avery says the eye-catching powerplant is good for 806 horsepower at the wheels. While undoubtedly fun to drive, the additional grunt made the Nova a bit of a handful with the pro-touring wheel and tire setup it had at the time.


โ€œIt just couldnโ€™t put the power down, so thatโ€™s when I went back to the drag stuff,โ€ he says.

The 4L80 transmission is paired with a PTC 9.5-inch non-lockup torque converter, which in turn sends power to the rear wheels by way of a Ford Explorer 8.8-inch rear end thatโ€™s been outfitted with 3.31 gears. A custom triangulated four-link rear suspension is matched up with Viking double-adjustable coilovers and Competition Engineering subframe connectors at the rear, while the stock-style front suspension benefits from tubular upper control arms from TRZ Motorsports and its own set of Viking double-adjustable coilovers.


Avery also gave the Novaโ€™s interior a comprehensive revamp, replacing a hodge-podge of Chevrolet and Pontiac pieces with a reproduction Nova upholstery kit from PUI Interiors and racing buckets from Procar, while a Maybee Kids Motorsports digital dash provides real-time data from a MegaSquirt EFI controller.

He says that aside from adding the four-inch cowl hood, the exterior is more or less as it was when he took delivery of the car back in 2012. โ€œThe paint was fresh when I got it, so that was one of the few things I didnโ€™t end up changing,โ€ he says. โ€œItโ€™s actually a factory color โ€“ Tripoli Turquoise. I hated it at first, to be honest. But everyone else who saw the car loved it, and it eventually kindaโ€™ grew on me. Itโ€™s not another black Nova.โ€


Completed in 2015, Avery has brought the Nova to a wide variety of shows in the years since, including several LS Fest East events. โ€œWe actually drove it down to Bowling Green for several of them,โ€ he says. โ€œAnd thatโ€™s kind of the beauty of this build. If you want to go cruise it, or take it somewhere for a date night, itโ€™s actually pretty comfortable to be in.โ€

It would seem that other folks concur with Averyโ€™s assessment of the Nova, as he actually ended up selling the car to another show-goer at last yearโ€™s LS Fest East. In the time since, Avery says his hot-rodding efforts have largely been focused on a โ€™71 Chevelle restoration for his father-in-law, along with an Eliminator Daytona jet boat build and a project that heโ€™s putting together with his son. โ€œThat same mini truck that I had in high school found its way back into my life again, so weโ€™re building it for my boy as his first project car,โ€ he says.


Avery also notes that all of his projects are motivated by LS power these days. โ€œWeโ€™re an LS-swap family at this point. Once I did the first one, I knew there was no going back.โ€
