The factory engine cover hinges on the Honda NSX were never designed around lightweight aftermarket NSX-R style engine covers. For targa owners, that usually means stacked washers, improvised spacers, alignment issues, and an overall unfinished installation. For coupe owners, aging OEM hinges can develop looseness in the hinge pin assembly, leading to an annoying vibration or rattle at certain RPMs. The HCE Performance Billet Engine Cover Hinges provide a clean OEM+ solution engineered specifically for both NA1 and NA2 NSX models. Designed and CNC machined in-house, these hinges are precision built to properly fit OEM and aftermarket NSX-R style engine covers without the need for modifications, drilling, or makeshift hardware. Whether you're restoring your NSX, building an OEM+ engine bay, or upgrading to a lightweight carbon fiber or aluminum engine cover, these hinges deliver improved fitment, durability, and refinement. Available Variants 1. Coupe w/ OEM Cover - Designed specifically for factory coupe engine covers while eliminating worn OEM hinge play and rattles. 2. Coupe w/ NSX-R Style Cover - A dedicated lower-profile hinge for coupe models running lightweight aftermarket NSX-R style covers. 3. Targa w/ NSX-R Style Cover - Features integrated hinge height to properly align lightweight NSX-R style covers without the need for washers or spacer stacks. Why These Hinges Matter Eliminate OEM Hinge Rattle Over time, factory coupe hinges can develop looseness around the hinge pin assembly. This often creates a metallic vibration or buzzing sound at specific engine RPMs. HCE's billet hinge design eliminates this issue while improving overall hinge rigidity and long-term durability. Stop Using Washers as Spacers Most aftermarket NSX-R style engine covers require crude spacer solutions to fit correctly on targa models. The typical solution involves stacking washers beneath the hinges to compensate for height differences. This creates inconsistent panel alignment, added installation hassle, increased vibration potential, and an unfinished appearance in the engine bay. HCE hinges integrate the correct geometry directly into the hinge design for a proper bolt-on installation. Features CNC Machined In-House Every hinge is precision machined from billet aluminum in-house for exceptional fit, finish, and consistency. Pressed-In Brass Bearings Integrated brass bearings provide smooth operation and improved wear resistance over factory-style hinge designs. Built-In Spacer Geometry Targa hinge variants feature integrated height compensation for lightweight NSX-R style covers — no washers or improvised spacers required. Direct Bolt-On Installation No drilling, cutting, or permanent modifications necessary. Threaded Mounting Holes Most variants feature threaded M6x1.0 mounting holes for easier engine cover installation and cleaner assembly. Hardware Included All necessary installation hardware is included with every set. Compatibility NSX NA1 and NA2 Compatible Covers OEM Coupe Engine Cover Aftermarket NSX-R Style Carbon Fiber Covers Aftermarket NSX-R Style Aluminum Covers OEM NSX-R Covers Important Notes OEM Targa engine cover compatibility is currently not validated due to the additional weight of the factory cover. Current targa variants are intended for lightweight aftermarket NSX-R style engine covers.
