In the realm of the modern sport compact, the list of power players runs short but strong. Holding the spotlight are such heavy hitters as the WRX, Lancer Evolution, S2000 and 350Z, while perennial favorites such as the Civic, Integra and RX-7 continue to thrive. But one theme remains constant throughout all the different models and types of cars, a distinct lack of luxury trimmings.

The Honda Civic was never designed as a Bentley killer, the Acura Integra shows its age and we've all heard the ever-popular complaints regarding the Evolution VIII's interior design. But, there's no reason to abandon all hope. You see, since 2003, Nissan's luxury branch Infiniti has been selling the up-market G35. Fit with a competent front-engine, rear-drive platform and the ubiquitous VQ35 six cylinder, the G35 coupe is literally a high end, backseat-equipped version of the 350Z. The same engine, the same power, the same suspension and the same massive stock tire clearance. But, stock is never quite good enough for the mad scientists over at aerodynamics manufacturer APR Performance.

For the fifth time in a row (sixth if you count a face update) APR has taken a stock specimen, infused it with more power, better looks and a wider body using a functional, clean factory appearance. From a Toyota Celica, APR moved on to a Toyota MR-S, Lancer Evolution VIII, Subaru WRX STi and finally this Infiniti G35. Starting with a stark white slate, APR's KC Chow spent precious time molding and sculpting a widebody kit for a debut at the 2006 SEMA Show. APR's widebody kit for the Infiniti G35 coupe features a factory-look front end and enough clearance for a ridiculous 325 millimeters of rear rubber. Accented by a Seibon carbon-fiber hood, APR's own front carbon wind splitter, Carbign Craft convex side mirrors and GTC-300 rear wing, this G35 was just barely finished in time for SEMA.

The attention to detail on APR's demo car shows through as well. Chow carefully selected a front bumper with dimensions that are both shorter and wider than stock to mate up with 45mm wider front fenders. The 50mm wider rear fenders were molded immaculately and the entire body was painted inside and out. TPR Autobody used a gold base coat before slathering on the ALSA Corp candy Blood Red paint. A meticulous shop, TPR repainted the entire car when a run showed up in the reflective candy paint, something not up to par with the level of this G35.

Steamroller 325-width tires may be great conversation starters, but for APR, there's a reason for everything. The 2003 Infiniti G35 rocks 280 hp, but that power level hardly warrants the use of meats this wide. APR juiced up the performance of their cruiser with the addition of twin turbochargers. Built by SP Engineering, the 3.5L V6 engine remains stock internally, relying on the VQ35's legendary reputation for sustaining abuse.

The twin turbo kit used here is based off of GReddy's offering, using GReddy exhaust manifolds, external wastegates and two TD05-18G turbochargers. SP Engineering custom fabricated the downpipes, which feed directly into a HKS Hi-Power dual exhaust. With no crossovers of any kind, the exhaust tract features a single exhaust for each bank of three cylinders. The mufflers gurgle and roar with each stab of the gas, with a tone that has more in common with a Porsche than an Infiniti.

The front-mount intercooler is a GReddy unit, with a fitting on the custom SP Engineering piping for a HKS blow-off valve. Twin turbocharger intakes can barely been seen on each side of the carbon-fiber Carbign Craft engine cover, with HKS Super Mega Flow air filters fit on to their ends. A Walbro high-flow fuel pump feeds larger-than-stock 440cc/min fuel injectors, with a stronger spark handled by a HKS Twin Power DLI II ignition amplifier. HKS' venerable F-Con V Pro standalone engine management system is used by APR, tuned by SP Engineering to put down 400 wheel hp and 364 lb-ft of torque at a modest 8lbs of boost. Off-the-shelf GReddy twin-turbo G35's and 350Z's normally put down about 350 wheel hp at SP Engineering.

The stock clutch was swapped out at this power point, exchanged in favor for an ACT clutch and flywheel kit. The stock six-speed transmission remains untouched, aside from a B&M short shifter, and is often mistaken for an automatic slushbox due to the shape of the Razo shift knob. APR's G35 is factory equipped with sledgehammer Brembo brakes, an option that was removed from the 2005 model year on. APR also fit two-piece front and one-piece rear Project Mu brake rotors, with a possible future upgrade to a Project Mu front big brake kit.

As opposed to their previous offerings, APR chose to build the G35 as a pimped-out street car, versus an all-out race car like their past Mitsubishi and Subaru projects. For stance, this Infiniti uses Hotchkis swaybars paired with softly tuned TEIN Comfort Sport coilovers. This coupe was driven to our studio for its photoshoot and Chow reported that its ride quality was dead on matched to its intended purpose. Dropped on to a set of custom 20-inch Maya MRS wheels with a black face and red lip, APR's G35 swallows up 285/25/20 front and the previously mentioned 325/25/20 rear Pirelli PZero Nero tires. The rear rims feature about 5 inches of glossy black wheel lip and Chow is already sourcing out a new set of Maya wheels, with a direct Lamborghini fitment. Those wheels will feature at least 6 inches of blingin' lip.

The interior is one area of this Infiniti that didn't need as much work as some other cars. APR uses a set of front recline-able Speed seats by Recaro, with Razo pedals and a Nardi steering wheel mounted on a Works Bell quick release rounding out the driver's interface. The dashboard also features custom mounting by Chow for in-car electronics, such as the TEIN EDFC and HKS EVC boost controller. The fiberglass mounting pod for the Autometer Nexus boost and oil temperature gauges is custom molded, fit right on top of the stock dash trim.

Because the stock stereo system was deemed inadequate, Pioneer Electronics was called in for help. A Pioneer AVH-P6800DVD double-DIN head unit is sitting ready to be installed, which features a six-disc in-dash DVD changer, 7-inch touch screen LCD display and XM/MP3/iPod control. Tunes are blasted out of crisp 260W max power TS-C720PRS 6.75-inch component speakers, while booming bass comes courtesy of a PRS-D2000T two-channel amplifier, which feeds a slim and compact 3.25-inch deep TS-SW3041D 12-inch subwoofer. Now rocking out at new levels of sound output, this G35 has all its bases covered.

From a widened body to twin turbochargers to a powerful stereo setup, the APR G35 is the complete package, in terms of both luxury and performance. You may not be able to grab a second glance from Porsche owners in your commuter Civic, but in the APR G35, that same monkey will find himself unable to pull his eyes away. Plus, with plans to upgrade the engine with HKS forged internals and go for 650 wheel hp, this G35 will be able to smoke that piece of Eurotrash in absolute luxury, no problem.

The show must go on, as they say, and so that’s exactly what organizers of the much-loved annual Tokyo Auto Salon did, taking the 3-day event that usually happens in Chiba’s Makuhari Messe convention center and translating it (metaphorically, not literally; it was still largely in Japanese) into both streaming video and 3D.

Super Street: Anytime we talk about a vehicle prototype, the overwhelming response, once some of the initial smoke has cleared (and people are done cursing out the manufacturer and demanding that their design team be fired immediately), centers heavily on claims that the production car will look nothing like the demo car. In some cases,

You know the name Joel Tan (@jt_built) from his wildly popular SR20DET-swapped, ‘40s-era Willy’s Jeep that mingles among the top of Super Street’s most popular feature cars of all time, and we expect his 1972 Nissan Skyline GT-R and Toyota Trueno of the same birth year will also have a lasting impression. Both cars feature

The “most powerful 3-cylinder in the world,” applied to Toyota’s much talked about GR Yaris still sounds a little strange when you hear it, but you can’t deny the nasty 250+hp and over 260 lb-ft. of torque that are delivered through an eager AWD system, all packed into a relatively lightweight (by modern hatchback standards)

As if to pour a little salt into the wound that the hottest hatch in ages, the AWD Toyota GR Yaris, is not being brought to North America, the interwebs has begun to conspire against us by teasing us with modified versions from some of the biggest tuners in the biz. In December, those sneak
