As promised, import car tuner GReddy debuted its X-Gen Street Genesis Coupe at the 2009 SEMA Show. Apart from the wild and wacky paint job (a SEMA necessity), the modified 2.0T model is the kind of car we’d like to have in the driveway.

The philosophy behind the build was to improve performance in all areas. GReddy calls this its “Total Tune-Up” theme. First up is what’s under the hood, with a larger turbocharger and an intercooler setup that produces 350-hp and 320 ft-lbs of torque for a 0-60 mph time of under 6.0 seconds. The kit is fully available from Greddy and includes all the other components, like the downpipe, blow off valve, etc. GReddy also offers the sweet looking quad-exhaust system.

That exhaust fits nicely with the JP USA rear diffuser. The rest of the car’s aerodynamics are also directly from JP USA.

In terms of improving performance in other areas, the GReddy Genesis Coupe gets a set of 19-inch Volk Racing G2 wheels wrapped in Toyo Proxes R888 tires. And inside those lightweight rollers is a GReddy big bake upgrade.

After much anticipation, Rhys Millen Racing has finally unveiled its mid-engined V8-powered Genesis Coupe at the 2009 SEMA Show. The RMR460 gets its name from the powerful Tau 4.6-liter V8, that has been borrowed from the Genesis Sedan. But RMR wasn’t satisfied with leaving the engine stock, instead choosing to upgrade the engine’s internals (with things like JE pistons) ad a set of eight individual throttle bodies for optimum throttle respponse and power. Output is rated at 500-hp!

Finally, a new transmission was needed to get all that power to the rear wheels and for that RMR went to Mendeola for a five-seed sequential box that allows the car to reach a top speed of 182 mph!

Additional modifications include an RMR Signature Edition Kit, a carbon fiber rear spoiler and rear hatch, Sparco seats and 20-inch HRE 560 series wheels, with some big 285/30/20 rear Toyo T1R tires.

As though there was any doubt, the 2009 SEMA Show is gearing up to be an exhibition of modified Hyundais. The tuning experts at GReddy have announced that they will be bringing a Genesis Coupe 2.0T, with all sorts of aftermarket goodies and an expected power output of 350-hp and 320 ft-lbs of torque.

Called the GReddy X-Gen Street Genesis Coupe, the Hyundai will get a larger turbocharger, MX racing downpipe, a front-mount intercooler and SE Spectrum Elite cat-back exhaust. A big brake upgrade and lowered suspension will also be a part of the package, as will a list of body modifications that include a carbon fiber front lip, hood and trunck. Volk Wheels and Toyo have also joined in to supply wheels and tires.

We’ll be sure to bring you more on the GReddy X-Gen Street Genesis Coupe, with coverage of the 2009 SEMA Show starting November 3rd.

How’s this for a school assignment: take a 2010 Hyundai Genesis Coupe, construct a twin-turbocharger system to make it pump out 500hp and present your work at SEMA.

That’s the task facing students at John Hennessey’s Tuner School.

Best known for his work with Dodge Vipers, Hennessey has assigned students at the State of Texas-accredited academy with the task of tuning the 3.8L V6 Genesis Coupe.

Students from the previous class got their hands on the Coupe first. Starting with a baseline 253hp on the dyno, the students constructed cold air induction and cat-back exhaust systems and mixed it a bit of nitrous. The end result, as you can see in the following video, was a jump to 380hp at the rear wheel.

Get the Flash Player to see this player.

With that class graduating, the current cohort has been asked to push the Genesis Coupe even further. The plan is to construct a twin-turbocharger system with a pair of GT30R turbos with the goal of topping 500hp.

The project Coupe will also be fitted with new wheels, gauges and aftermarket seats to make it presentable at the 2009 SEMA Show in Las Vegas, starting November 3rd.

A Hyundai will no doubt be one of (if not the) coolest vehicle at the 2009 SEMA Show. Rhys Millen Racing, which runs a Genesis Coupe drift team, will debut a mid-engine version of Hyundai’s sports car at the aftermarket parts venue. Better yet, instead of using the turbo four-cylinder or the 3.8-liter V8 motor, Rhys Millen Racing (RMR) has opted to swap in the 4.6-liter V8 from the coupe’s luxury sedan sibling.

And as RMR is a race shop, there are promises of even more than the stock 375hp thanks to some high-compression pistons and individual throttle bodies. The factory automatic transmission will be tossed in favor of a racing-style sequential unit

RMR hopes to retain as much of the stock suspension as possible on the car (which has been code named the RM460), with a set of StopTech brakes and a new set of wheels fitted with Toyo T1R tires (measuring 245/35/20 up front and 285/30/20 out back).
