SEMA always manages to present some fascinating (and baffling) modified cars to sit alongside the styling specials from big-volume manufacturers like Chevrolet and Ford. LUX Motorwerks has provided one of these by boosting the Kia K900’s 5.0-liter V8 with two boot-mounted turbochargers, to create the inventively-named Kia K900 High Performance.

The addition of the two turbochargers boosts the engine’s output from 420 hp (313 kW) to around 650 hp (485 kW). Apparently mounting the bespoke Garrett 2871R turbo setup in the boot helps to cut down on “engine compartment heat build-up” under heavy acceleration, and “doesn’t require the removal of any sheet metal” from the hood – or perhaps the turbos just didn’t fit in the front.

This unorthodox turbo setup is clearly visible through a special port in the boot, which is flanked by a ProDryer helmet dryer and race suit compartment, something designed to fulfill Kia’s brief of a luxury car that can ferry race drivers to and from the racetrack.

The car on display in Las Vegas is also fitted with a unique styling package that includes a one-off bodykit, blacked out chrome trim and gloss-black 21-inch wheels, which are coupled with Pirelli tires. Behind those 21-inch wheels is a set of Ksport 8-piston brake calipers, which clamp on 15-inch cross-drilled rotors. The K900 High Performance is also lower than the standard car, thanks to Eibach suspension.

The seats are trimmed in tan leather with black suede inserts and carbon fiber trim has been added on the steering wheel. The interior makeover also includes 11-inch monitors mounted for rear seat passengers, which are playing footage from online racing game iRacing.com at the show.

When SEMA closes, there is no word from Kia or LUX as to when the K900 High Performance will make another appearance.

650HP and Massive turbo lag. I don't get it.

There are ways of dealing with turbo lag. My favorite is to is to turn the compressed air duct into a tank using a one way valve by the turbo and a control valve just in front of the throttle body with another one way valve so when idling the engine is getting uncompressed air. Then when you touch the throttle the tanks control valve opens providing instant power.

Its a 5.0l v8 making 420hp stock. The jump to 600hp is not that great a leap. As someone who has built boosted 6 and 4 cylinder cars, I can tell you, there will be little, if any lag in a vehicle like that. The displacement of the engine is more than sufficient, the head flow on modern engines is more than enough and the turbos are most likely ball bearing so boost responce is good. Also, its not running enough boost pressure to feel "laggy". Lag comes from smaller displacement, low compression, poorly flowing 4 cylinder engines or overboosted, small displacement engines coupled to large turbochargers. When jumping from 150 or 200 hp to 700hp, it cannot necessarily be helped, but when you've got 400+ hp on tap already, there will be no lag to speak of.

@ Michael Wilson.....Its a bigger leap than you seem to think, it is actually 650hp not as you say 600hp....That is a jump of 180hp which in any language is a big leap, that is a 43% increase on the stock HP figure of 420hp.....
