1989 Mitsubishi Mirage Turbo
It cost the owner just 44 cents to keep this one-of-900 precurso to the Turbo Eclipse, Galant VR4 and Lancer Evo on the road.

As long as Mitsubishi has been selling its own cars in the United States, turbocharging has been an important part of its performance image. Back in the '70s, when Mitsu-built Colts and Champs were rolling out of Dodge and Plymouth stores seemingly faster than Aspens and Furys, turbos weren't on the menu. But once the Three Diamonds established themselves on American shores in late 1981, their availability was scattered throughout the line: The rear-drive Starion 2+2 was most prominent, but even the Accord-competitive Tredia sedan and Cordia hatchback had available blown fours under the hood. The early '90s brought us the Diamond-Star-built Eclipse and the mondo twin-turbo 3000GT VR-4, as well as the sadly short-lived Galant VR4. More recently, the Lancer Evolution has carried the turbo torch. Little wonder, then, that the company manufactures their own turbochargers.
But there's something missing from the impressive and under-appreciated roster listed above. Starting in the mid-'80s, Mitsubishi offered turbo power in its smallest, lightest U.S.-bound car: the Mirage, as well as the identical "captive import" Dodge (and Plymouth) Colt. Sales didn't reflect the media's mostly positive reviews, as enthusiasts preferred VW GTIs and Toyota Corolla FX16s, but the Turbo Mirage/Colt was interesting--and it kept up the company's reputation for turbo power.
Starting in 1989, a new generation of Colt was also sold through Mitsubishi outlets as the Mirage (its Japan home-market name, Lancer, was ironically owned by Dodge for a K-car-based family ride of their own). In 1989, $13,000 bought you a newly designed subcompact with a 93.9-inch wheelbase, a sub-2,500-pound curb weight and, most importantly, a twin-cam, 16-valve, turbocharged, 1,595cc four with 135hp and 141-lbs.ft. of torque on tap.
This engine, designated 4G61T, was tweaked to generate 30 percent more power than the previous year's model, is a junior version of the two-liter turbo terror that ended up in the first-generation Eclipse (and is grandfather to the mighty 4G63 that powered all but the newest Lancer Evolution models). The body offered few, if any, clues: Only the chubby wheels and tires, and maybe a discreet TURBO badge somewhere on the rump, distinguished it from lesser Mirages. Automobile magazine characterized the juxtaposition of mild style and wild power as both "pleasantly schizophrenic" (though, admittedly, they were driving a Plymouth Colt). The Colt version also made Car and Driver's annual "10 Best" list for 1989.
Allen Froschauer of Long Beach, California, now supervisor for Mitsubishi's engineering center and within months of his 20th anniversary with the company, recalls those first Turbo Mirages from his earliest days there. "I remembered those Mirages, and in late 1993 I started looking for one. I found this one in mid-1994." Why'd it take so long? For one thing, roughly 900 Mirage Turbos were sold in the States before Mitsubishi pulled the plug--there just weren't that many around to be found. "There were also some turbo Colts sold through the Dodge dealers at that time, but they're even more rare than the Mirage. The only difference [besides badging] was that the Colt had power windows."
When he bought it, the paint was red and shiny, the clear coat was intact, the window tint hadn't started to bubble, and it had less than 50,000 miles on the clock. It is ostensibly his daily driver--"I was doing 65 miles one way for a few years, but now I'm less than 15 miles from work," he says--but extenuating circumstances, and his job, explain why there are just an additional 40,000 miles in 15 years of ownership. "Really, how often I drive it is variable. I'm in a unique position--I take care of press vehicles and product-support vehicles, and also investigate engineering concerns. Maybe I'll drive it to work one day, and I'll have a company car for a weekend to diagnose something. Or maybe I'll drive it two days a week, and have another car for three days."
Now, in so many pockets of the old-car hobby, newer cars are slighted by collectors as being irreparable, thanks in part to the Byzantine electronics that they tend to be saddled with. Not so: You just need to know what to look for. "Like all things electrical, over time the components break down. We had heard that customers sometimes struggle with getting control units on their older cars replaced or fixed; we'd also heard that capacitors had been popping on the ECUs.
"I went to drive it one morning about three years ago, and the injector was just running and running...it was just a guess on my part, but we put a 'noid light on the injector, to see whether it was pulsing or not. If it's just on, with no pulsing, then you've lost the ground on the control side of the circuit. Well, the injector was short-circuiting to ground and staying on. I pulled out the ECU, and the capacitor had bled its cooling fluid out onto the circuit board and shorted the injector controller."
For most, it might sound like disaster--or at the very least, an expensive repair bill. Not for Allen. "I got lucky pulling the popped capacitor off the circuit board--you can damage things if you apply too much heat--and I replaced several others that looked suspect. All I did was compare the microferrets with what was there originally, and swapped them with what came off. They're available through Radio Shack or a good electronics supply place." The cash outlay for this high-tech fix? "Forty-four cents for the capacitors," Allen recalled. That's right, for the cost of tipping your barista when you get your morning coffee, you too can fix your Mitsubishi. Further concerns about frying the circuit board while resoldering everything into place were unfounded.
Over the years, a couple of small changes have made their way onto the Mirage. "The wheels are 15 x 6.5 Team Dynamic Revos. The tires on there now, the Yokohama A008s, are actually OE spec and are in a size [205/60] that aren't made anymore. I changed the exhaust tip in 1998 just because I wanted a different sound. Inside, I installed a Japan-spec white-face tach. It's got the same font as my original gauges, and I like the black-and-white look. And the shift knob is from a Lancer Evo MR...I thought it looked cool, even though my Mirage isn't a six-speed."
Other changes have come without Allen lifting a finger: Among others, the clear coat has flaked away under the relentless California sun, and the once-red paint is fading to pink. "I'd like to paint it...I'm really not happy now with the color." Beyond that, he harbors no plans to change anything: "I'm just going to enjoy it as much as I can." That enjoyment, however, must come alone. "It's not a great family car--if you have bigger kids, it doesn't work well. I have two adult-sized kids--aged 16 and 14--and they're too big. The passive belt worked fine in its day, and it's fine for me, but without airbags, I don't want to put anyone I love in it."
Other than the paint and the wheels, this is surely one of the few remaining stock Mirage Turbos around. Swapping an Eclipse two-liter under the hood, popular among those who owned and modified these cars, has never been a part of the plan. Besides, we all know how originality counts on the collector-car market...right?
"You know, right now the list of collectible Japanese cars is really pretty short," Allen said. "The Mitsubishi Mirage turbo isn't like a 510, Datsun Z, or even a Datsun 1600 or 2000 roadster. Mitsubishi, in this country, doesn't seem to have a following for collectibility. Maybe someday, with the first-generation Eclipse...." And maybe someday, when electronics-generation machines achieve the collector cachet of their forefathers, and when the Japanese collector-car market more fully matures, low-production machines like the Mirage Turbo that helped pave the way for other more blatantly sporting models will take their rightful spot in the pantheon of collector-interest cars. Until then, Allen Froschauer will be driving his, enjoying every mile.
Chevrolet made waves in ’01 when it brought back the Z06—a bona fide track-day-ready, package for America’s sports car. This hot new Corvette wasn’t exactly all-new, however. It was an evolution of the “fixed-roof coupe” (FRC) introduced in 1999 and aimed at performance-minded buyers looking for a lighter, cheaper, more rigid Corvette. A six-speed manual was the only transmission available on those earlier ’Vettes and the Z51 suspension was standard issue. Interior choices were limited to: standard buckets (optional sports seats weren’t available); and black upholstery. Niceties like the optional power telescoping column or a power passenger seat weren’t offered. Today the FRC is an unusual find, as just 4,031 were made in 1999 and 2,090 in 2000.
The Z06 took the FRC to the next level, though the tradeoff was a higher price tag: approximately $47,000 for the ’01 Z06, versus $38,000 for the ’99 FRC. For the money, buyers got the best speed parts and engineering tweaks Chevrolet had to offer: the LS6 engine, initially rated at 385 hp, then 405 hp; a six-speed manual with more aggressive transmission gearing than standard; a titanium exhaust system; thinner glass; Goodyear Eagle F1 SC tires mounted on lighter, stiffer forged aluminum wheels; less sound-deadening material; a fixed radio antenna instead of a power antenna; and a smaller, lighter battery. The car also introduced rear-brake cooling ducts integrated in the rear fenders, which would become a signature Z06 styling cue. At less than 3,200 pounds, the Z06 weighed 36 pounds lighter than the FRC, and 117 pounds lighter than the standard coupe or convertible.
One of the ultimate C5 Z06s was the 2004 24 Hours of Le Mans Commemorative Edition, acknowledging Corvette Racing’s historic 1-2 class finishes in 2001 and 2002 (also 2004). Just 2,025 Le Mans Commemorative Editions were built assuring their collectability.
As far as the regular Z06 goes, all told, there were 28,388 built over four model years, so they’re not difficult to find these days. It can, however, be difficult to find stock, low-mileage examples, as many owners drove these cars as they were intended and tweaked them with bolt-ons for even better performance.
According to classic.com, average C5 Z06 prices have increased significantly over the last five years from $16,000 in 2019 to $32,000, as of this writing. One of the highest prices recorded for an unmodified example was at Mecum’s Kissimmee sale in January. The car was a 2001 painted Speedway White (one of 352 in that color) with just 218 original miles, and it sold for $71,500 including fees.
In July 2023, a black 2004 Z06, driven fewer than 1,600 miles, sold on Hemmings Auctions for $52,500 - just shy of the car’s original MSRP of $53,485. On the more affordable end, back in 2020, a 2001 Z06 listed as unmodified, but with 154,680 miles on the odometer, changed hands on Hemmings Auctions for $9,000.
These cars have received a lot of attention lately and appeared on many bargain-priced performance car listicles. Their low-buck status seems to have changed as a result and prices have nosed skyward. Still, the first-edition Z06 is an excellent car that offers a lot of track day potential with very low running and maintenance costs. If you’re interested in owning a 2001-’04 Corvette Z06, here are some points to consider.

C5 Corvettes used sheet-molded composite body panels made of 40 percent resin, 33 percent calcium-carbonate filler, 20 percent chopped fiberglass, and 7 percent resin and hardeners (used to improve the surface finish of the panels), according to Chevrolet. The floor pan was made from SMC inner and outer panels with balsa wood sandwiched in between. The 2004 Le Mans Commemorative Edition Z06 used a carbon fiber hood to shave 10 pounds off the nose. When inspecting a Z06, you’ll want to inspect the lower portions of the car for signs of damage—the fascias and rocker panels. The three-piece air dam on the front is prone to taking hits because it rides so close to the ground. Replacement air dams are widely available and it’s important that the pieces be installed correctly as the dam helps direct air to the car’s radiator. You will also want to check the floorpan for signs of damage or previous repairs. Floor pans punctured by debris in the road aren’t unheard of on these cars and you’ll want to make sure the repair was performed correctly to guard against leaks. The quarter panels on these cars are bolted on, so check for proper fit and signs of replacement that might indicate previous accident damage. Aftermarket body kits are available for C5s and popular with Z06 owners looking for some additional body width and larger wheelhouse openings.
Something else to be aware of - common among all Corvettes, not just C5s - are electrical grounding issues related to the composite body. These can cause a wide variety of mysterious conditions and usually the problem isn’t difficult to solve but can be difficult to trace.
Z06 exterior colors over the C5 generation included: Black, Torch Red and Millennium Yellow from 2001-’04; Speedway White, which was only available in 2001; Quicksilver, which was offered from 2001-’03 and replaced by Machine Silver in ’04; Electron Blue, which was offered in 2002-’03; and LeMans Blue Metallic was used on the ’04 Le Mans edition Z06. All of the LeMans editions were painted blue with silver and red graphics modeled after the 2003 C5R race car.
Among the most scarce of all C5 Z06s is 2004 24 Hours of Le Mans Commemorative Edition acknowledging Corvette Racing’s historic 1-2 class finishes in 2001 and 2002 (also 2004). Just 2,025 Le Mans Commemorative Editions were built, and they command a premium today. All of the LeMans Commemorative Editions were painted blue with silver and red graphics - a color scheme modeled after the 2003 C5R race car.

The C5 Z06 was based on a pair of 13-foot long, continuous chassis rails, hydroformed in a die using fluid pressure - it was a very rigid platform and a first for the Corvette. Another substantial change in the C5 chassis, that made it an ideal production road racer, was the use of a rear transaxle. By moving the gearbox to the rear, the weight distribution nearly hit the 50/50 sweet spot, plus it freed up space in the cabin. An enclosed stamped-steel driveshaft tunnel (a torque tube) between the engine and the transaxle made the chassis even stiffer. The suspension hard parts were made from aluminum and transverse mounted leafs handled the bumps. The C5 front suspension used a setup similar to the late-edition C4s, with revisions, while the rear was an entirely new design with upper and lower A-arms and constant velocity joints replacing the old five-link/universal joint setup. Without a doubt, the C5 chassis transformed the Corvette. In addition to the superior handling, the cabin was easier to enter and exit, more comfortable to drive and the ride was less punishing—even the track-ready Z06. To ensure the Z06’s track readiness, it had unique FE4 suspension with a larger front stabilizer bar, a stiffer rear spring, revised camber settings and forged wheels that were 1-inch wider front and rear than a standard Corvette. The Z06’s steering was sped up too: 2.46 turns lock-to-lock versus 2.66 on standard C5s. Brakes were shared across the C5 line—four-wheel discs with 12.8-inch rotors front and 12-inch rear. The calipers were two-piston units but treated to a red finish on the Z06. Many owners choose to upgrade the stock brakes with aftermarket units. The stock rotors are fine for street use but have shown not to hold up well on cars that are driven hard on the track.
The 2004 model year Z06 benefitted from suspension revisions and new shock absorbers that were developed by GM through extensive testing. These units were a vast improvement over prior years. There are aftermarket options available that approach the performance of the factory ’04-edition shocks—which can be expensive and difficult to find today. Many owners have found that OEM C6 Z06 shocks are also a good fit at a lower price. The C5 chassis is a rugged and proven sports car platform that was designed to serve reliably for many miles. When shopping, take note of the typical items that wear out with age: anti-sway bar bushings/end links, control arm bushings, rear cradle bushings, ball joints etc. Be sure to ask about any maintenance work that might have been performed. A fresh set of tires is a selling point on these cars as well. The stock size Eagle F1 tires cost more than $400 apiece for the 265/40R17 fronts, and more than $600 apiece for the 295/35R18 rears - if you can find them. The selection of tires available in the factory sizes is limited these days so when it comes time for replacement you might have to consider alternatives like 255/40/17 or 275/40/17 fronts and 285/35/18 rears.

The 5.7-liter LS6 arrived in 2001 with 385 horsepower and made the jump to 405 horsepower in 2002. It was an evolution of the standard Corvette’s LS1 with improvements to the block and pistons, better flowing heads with revised combustion chambers, a more aggressive camshaft, a redesigned intake and more. The LS6 is an excellent and proven performance engine that will serve many thousands of trouble-free miles. Initially, excessive oil consumption was an issue, but the problem was addressed in a Technical Service Bulletin. Replacement piston rings (due to a sealing issue) and a replacement engine valley cover (due to leaking) were prescribed for circa-2001 engines affected, and the changes were made in production to later LS6s. Reports and discussions of valve spring failures on 2002-’03 engines in particular also abound on internet forums. Replacing valve springs is a relatively cheap and inexpensive upgrade and is worth considering if the seller hasn’t performed the work already. Some of these engines have also suffered from separated harmonic balancers and balancer bolts that loosen and allow the balancer to come off - check for a wobbling lower engine pulley when the engine is running. The factory balancer is a press-on fit but there are aftermarket versions available that can be pinned to the crankshaft. Upgraded balancer bolts are also available.
The Z06’s instrument cluster bears the logo of the popular performance package, and the tach has a 6,500 rpm redline.

The Z06 used the TREMEC T-56 gearbox but it was equipped with more aggressive gear ratios for harder acceleration than the base Corvette. The trans was rear-mounted to a Getrag differential shared with all C5 Corvettes. Z06s were equipped with a 3.42:1 gear set with shot-peened ring and pinions.
The T-56 is an excellent gearbox, but miles and abuse can take a toll leading to some of the typical manual transmission maladies: grinding between gears, sticking in gear, popping out of gear etc. Sometimes the issue can be as simple as the shifter or the mount being loose, but some of these symptoms could also be signs of worn synchros or a damaged shift fork. The good news is parts are widely available and finding a knowledgeable rebuilder isn’t difficult.
The C5’s Getrag differential is a bulletproof and reliable unit that can withstand plenty of driving and punishment. The biggest issue with these has been seal leaks—something that was addressed in a circa-2003 technical service bulletin covering all C5 Corvettes. The TSB recommended replacement of the output shaft seal and the differential side cover O-ring. If a Z06 you’re looking at hasn’t had the work done and appears to be leaking, those seals are likely the culprit—and most frequently it's the output shaft seal. (Some techs recommend not disturbing the side cover if it isn’t leaking.)
Some C5 owners have also experienced issues with the clutch pedal sticking in the down position or returning slowly. Sometimes this can be solved by flushing and replacing the fluid in the hydraulic system. There are also aftermarket clutch return spring kits that can deliver more positive pedal action - once the fluid has been replaced and the system bled (an important maintenance item).
Z06 interiors were black or black with red accents and embroidered headrests. The Le Mans Commemorative Edition (shown) had graphite-colored upholstery with the Corvette emblem in the headrests instead of the Z06 logo.

C5 Z06s had a unique instrument cluster with a Z06 callout on the tachometer and a 6,500 redline indicated. The bucket seats had additional side bolstering and embroidered Z06 logos on the headrests. Colors were limited to black, black and red and there was a graphite-colored interior for commemorative-edition ’04s with the Corvette crossed-flags emblems stitched into the headrests. It’s common to see worn leather side bolsters and seating surfaces in these cars but there are aftermarket covers and kits available to update shabby looking buckets. Many owners have complained of wind noise in C5s as the window seals age. Water leaks around the weather stripping is also a common problem. A locked steering wheel that can’t be unlocked, accompanied by the “Service Steering Column” message on the driver information display was one of the most common C5 interior issues reported. A 2004 recall addressed the issue (the recall number was 04006) and any car you’re considering should have had the recall work performed. Some owners took matters into their own hands and installed an aftermarket bypass kit that allowed the lock to function without interference from the car’s body control module. These seem to solve the problem as well.
The Z06’s LS6 V-8 is generally a dependable engine. Horsepower was rated at 385 in 2001 and 405 from 2002-’04. Broken valve springs are a known issue, particularly on some 2002-’03 engines.
