Clarion Builds 1991 Acura NSX Review | Restored to greatness

Few automobiles garner as much mystique as the original Acura NSX. I worshiped this car from afar, consigned to the fact that the closest I was ever going to get to the steering wheel was a Playstation controller. When I got the email inviting me to drive Clarion Builds' restored and tuned 1991 NSX, I thought it was spam, a chain email with some generic header sent to a dozen or so people to garner some press coverage. Surely this wasn't a real invite where I get to drive a real NSX using my real hands and feet. Some people say don't meet your heroes. Some people are wrong. I knew the car by reputation. In roughly 10 months, Clarion Builds, a division of the Japanese electronics company mostly known for high-end audio systems, worked with partners like AEM and AutoWave to transform a '91 NSX with nearly a quarter-million miles on the clock into what you see here. Everything, from the engine to the bodywork to the leather on the seats, has been upgraded and restored with a mix of both OEM and aftermarket parts. The final product is a stunner. It's tuned, but not slammed, stanced or any other adjective that describes a car with compromised performance and questionable looks. It's simply a tastefully tuned NSX. The NSX, especially an early car with pop-up headlights, is one of the all-time great car designs. There are no unnecessary lines or curves. It's all purposeful. As expected with something with 230,000 miles, this NSX had a number of dings and dents. Clarion Builds has fixed those, replacing the hood and spoiler with carbon-fiber parts from an NSX-R. The fenders are slightly wider than stock, helping cover the staggered Rays Engineering VOLK ZE40 wheels, 18-inch up front and 19-inch out back. After seeing it in the flesh with the blue paint, black roof and bronze wheels, I don't think there is a better fit for this car. The original but tired 3.0-liter V6 and five-speed manual have been swapped for a 3.2-liter V6 and six-speed manual from a 2004 NSX. Stock, this engine is a wonderful ode to the internal combustion engine. It sings a sweet song all the way to a sky-high 8,200 rpm redline. Still, it wasn't enough. The engine now wears a Whipple-style supercharger, pushing roughly 9 psi of boost. Other modifications include a one-off carbon-fiber intake, a hand-built exhaust and a new ECU, all from AEM. All in, Clarion Builds says this NSX makes 403 horsepower and 296 pound-feet of torque at the wheels. God, it feels good to push this thing.

2020 Acura NSX Suspension Deep Dive

The Acura NSX has been a special car as long as I’ve been in the business. The first one came out in 1990, the same year I started my career in automotive engineering. I vividly remember driving one briefly back then when we brought one in for benchmarking. I'd drive it again 22 years later when my previous employer bought a used 1991 example for a long-term test. Reader interest was sky-high and the car was still gorgeous, but the march of time and automotive engineering had clearly left it behind. Then, in 2016, a second-generation NSX emerged, and it was packed with bleeding-edge thinking. It has a 3.5-liter twin-turbo V6, but this new NSX is a hybrid with an electric motor-generator sandwiched between the engine and its nine-speed DCT transmission. Two more electric motors – one for each wheel – power the front axle. There they can add traction, regenerate electricity under braking and dole out hyper-accurate levels of torque vectoring. The carÂ’s tire package was changed from Continental SportContact 5 to SportContact 6 tires in 2019, and numerous suspension re-tuning tweaks came along with them. The result is a lively and well-balanced car that is relentless when driven hard and a pussycat around town. LetÂ’s see what theyÂ’ve got going on under there.   At first glance the 2020 Acura NSX appears to have dual wishbone front suspension. But we canÂ’t tell for sure because that big two-piece brake rotor is in the way. The coil-over shock looks obvious, but a few odd details are apparent even from here.   This view also seems to indicate double wishbone suspension. But the pivot axis (green arrow) between the upper and lower ball joints looks wrong – itÂ’s far too vertical. WeÂ’re missing something. But I would be remiss if I failed to point out a few other things before we moved on. For one, the front drive axle confirms this to be an all-wheel-drive machine. Second, the forged aluminum damper mounting fork (yellow) that envelops the axle is mounted to the lower arm about 75% out from the armÂ’s inner pivot. The spring and damper motion ratio would be 0.75-to-1 relative to wheel movement, with a tiny reduction due to its lean angle. Lastly, just look at the huge cast aluminum upright (white). Beautiful. Normally these are called hub carriers or steering knuckles, and I use the terms interchangeably. But the motorsports-derived term upright is normally applied when the piece is tall and, well, upright like this one.   This explains everything.
