In order for a vehicle with this much power to handle effectively, Factor X set up a Tein RA front and rear suspension system. Also added to the front end are a Comptech anti-sway bar and tie-rods. Rear stiffness is enhanced with an Alex Zanardi Edition anti-sway bar.
Braking is provided by RB 11.7-inch slotted rotors and 1997 NSX calipers paired with Project Mu pads. Goodridge stainless-steel brake lines with Motul fluid pumping through them gets the stopping message to where it needs to be.
Further aiding in the track performance of this NSX are the Volk Racing CE28N wheels which run 17x8 inches in the front and a fat 18x10.5 inches in the rear. This NSX didn't reach the 10-second barrier on the quarter-mile by using inferior tires. It runs Falken FK-451s sized 225/40-17 in the front and 295/35-18 BFGoodrich Drag Radials at the rear.
After initially going with their custom single-turbo setup, Factor X progressed to their current twin-turbo format. The goal for the development of the twin-turbo kit "was to produce in excess of 600 rwhp with smooth power delivery." The NSX is intended "to be a dedicated road course vehicle.
But of course, since Mike [Angel] was involved a small shot of nitrous was installed for those days it goes to the quarter-mile track." On nitrous the power output jumped to a staggering 813 rwhp. Could this be the most powerful street driven NSX in the U.S.? It is a big country so the truth remains a mystery.
Factor X Racing is very satisfied with the results of their 1993 NSX build and has evengreater plans for their 1991 Comptech widebody NSX. You can see them represent at The Strip at the Las Vegas Motor Speedway and many local NHRA events. So far they have run a best of 10.68 at 138 mph.
Finally, a bit of reflection from the guys at Factor X: "The road has been a verylong one and many times we questioned ourselves on what the hell we were doing. We are sure glad we followed our heart instead of our head."
