Acura Concept - Acura NSX Engine

 Spoon Sports' NA1 NSX Engine

At the encouragement of its U.S. sales and marketing arm, Opak Racing, Spoon purchased a pair-no more, no less-of used LHD chassis from Japanese private parties for experimentation. North American-spec, LHD chassis are not an uncommon sight in Japan due to the country's lax importation regulations in comparison to the U.S. In other words: The two chassis are not of North American origin, and Spoon will not be converting RHD NSX chassis to LHD specifications. It won't need to.

the NSX's engine, you ask? Well, should you, really? We guess you're a bigger masochist than we thought. This ScienceofSpeed Acura still holds onto the factory 3.0L V-6 powerplant with a sleeved and bored block, increasing the engine to 3.3L, with custom forged pistons. The intake valves, driven by custom stage 2 camshafts, were also enlarged. And if you look closely at the engine picture, you'll see an individual throttle body system. Now that's as uncommon as us finally getting an NSX and kissing a girl. "By our calculations, the engine and induction package should be good for about 320-340 wheel horsepower, which is about 100 hp above factory output

 To find more useable low-rev grunt for the street would require the addition of forced induction, which often comes at the cost of reliability and civility. Piercey went with the smog-legal and reliable non-intercooled Comptech supercharger kit, driven to 6psi of boost. The Version Two unit uses a positive displacement Autorotor compressor, which (according to Comptech) is 10 percent more adiabatically efficient, easier to package and offers better maintenance access compared to the original Whipple 1600A compressor, which was phased out for sourcing reasons. This gave some much-needed low-end push for the street, where high engine speeds aren't easily maintained.

The system is available in Stage I trim (60mm turbo, rated to 600 rwhp), Stage II (67mm turbo, rated to 700 rwhp) and Stage III (76mm turbo, rated to 850 rwhp).  All turbos may be ordered with ball bearing option.  The Stage I and II systems can be installed on stock engines, but boost levels should be limited to about 10-11 psi or 500-550 rwhp maximum; the Stage II and Stage III systems will require internal engine modifications to utilize the full power potential of this turbo.  Other options available are a wide-band tuning module (for street tuning), in-car boost controller, gauge packages, injector and fuel system upgrades.

The 2012 Acura NSX engine will probably be a V6, with a cylinder capacity of 3.5 or 3.7 liter; the power output will be connected to a seven-speed dual-clutch gearbox that in its turn is connected to the rear-wheel drive. The Acura NSX also features two electric motors, for a total hybrid power output of 400 horsepower.
 

What is so special about this 2012 Acura NSX is its hybrid drivetrain and some new Acura NSX accessories. This may seem odd for a supercar, but bear in mind, that the Acura NSX engine will still deliver over 400 horsepower. Due to this power we expect the new Acura NSX to perform well both on the racetrack and on the road.

Las Vegas is a crazy, crazy place. This is common knowledge already, thanks to Vegas' healthy reputation as the headquarters for sin. But don't think for a second that alcohol and gambling are the only after-school specials going down in excess. The town is just as much a haven for speed addicts as it is for poker addicts. Nestled away from the bright lights and billboards of the tourist-ridden main strip is Factor X Racing, one of the nation's premiere builders of turbocharged Acura NSX's. It's not uncommon to see Factor X-tuned mid-engine rocket ships cruising through the streets of Las Vegas, all of which are packing north of 500 hp.

This blue 1993 Acura NSX, owned by Vegas resident Paul Siu, is outfitted with Factor X's FX500 turbo package, which is designed to push more than 500 hp. Two years ago, before Sui seriously started this build, his NSX was much more mild. Acura's flagship provided massive thrills at first, but an addiction to power soon took over and mere bolt-on parts wouldn't cut it. As an employee of the extravagant Bellagio resort and casino, Siu is used to seeing his fair share of high rollers. But when your neighbors start coming home in Porsche 911 Turbos and Lamborghini Gallardos, you know it's time to step up the game on your NSX.

Siu started the build on his NSX by laying the supporting foundation for high horsepower first, and then adding the turbochargers later. Smart man. Bigger tires would be necessary to contain the upgrade in power, and Siu didn't cheap out. A set of 225/25/18 front and ber-wide 315/30/18 rear Michelin Pilot Sport tires were stretched on to custom Burning Black Work VS-SS wheels. The front ten-spoke beauties are 8 inches wide, but the rears measure a whopping 11 inches across. Filling up the void behind the front Work wheels is a four-piston AP Racing big brake kit, which is an especially wise investment considering how fast this NSX really is.

In order to cover these enlarged rollers, some new bodywork was in order. Once upon a time, this NSX wore a Wings West body kit and stock fenders, but the new rubber convinced Siu to upgrade to the Cantrell Studios widebody conversion kit. The front end still wears the same Wings West front air dam and louvered carbon hood, but the front fenders and rear quarter panels were traded out for Cantrell's widened and flared pieces. After adding a Taitec rear diffuser and massive MAX Racing rear wing, this NSX began to live up to Siu's nickname for it: the Blue Devil.

But no devil would be complete without hellfire. Driving down a desert highway to work one morning, Siu received a honk from a pickup truck and a simple shout, "You need a turbo!" As it turns out, that truck was driven by none other than Factor X mad scientist Mike Angel, who was spreading the love of NSX turbos his own way. Angel's FX500 turbocharger package was whipped up for the car, designed to put out more than 500 hp on pump gas. Siu's FX500 system began with the removal of his stock C30A and the installation of one of Factor X's spare race engines. Larger 93mm bore Wiseco pistons are hung on rebushed stock titanium connecting rods, along with the stock forged steel crankshaft. The cylinder heads are ported by Portflow and were finished with new valves, springs and retainers before re-installation.

The turbo portion of the kit uses a secret-spec turbocharger, which is mounted low down and away from view. Connected to modified Comptech headers, the turbo blows into a custom downpipe and out the Taitec JGTC center-exit exhaust system. This NSX uses a Cantrell Concepts air induction system, which scoops cold air out of the fender well and feeds it into the stock air box. A Factor X in-tank fuel pump feeds thirsty 720cc/min RC Engineering fuel injectors, based on the tuning of the HKS F-Con V Pro standalone engine management system. Factor X has tuned the car seamlessly for daily driving, and with the turbo system hidden low and away from view, this NSX's engine bay could almost pass for stock. That is, until the first rip of the throttle.
