S2000 to K20A Swap Engine Mounts V2 with AC Bracket | Grid Collection Limited Edition | RBZ Harmony

RBZ Harmony Grid Collection — S2000 to K20A Swap Engine Mounts V2 with AC Compressor Bracket

A complete engine mounting solution for the Honda S2000 AP1 and AP2 chassis with a K20A swap. The kit includes a redesigned 4-point L Mount, a refined R Mount with improved header and turbo clearance, and a plug-and-play AC compressor bracket that replaces the OEM unit while retaining factory air conditioning. Compatible with any S2000 style engine mount. Finished in Cerakote with Japanese Industrial Standards (JIS) Grade 10.9 hardware and genuine Nord-Lock wedge locking washers. Designed, machined, and welded at our Florida Atelier.

🟤 4-Point L Mount — Four mounting points distribute engine load over a larger area for added durability under hard driving.

🟤 Plug-and-Play AC Bracket — Replaces the OEM AC compressor bracket without cutting or drilling, retaining factory air conditioning.

🟤 Mount Compatibility — Accepts any S2000 style engine mount, including Mugen, Spoon, Hardrace, Megan, Vibra-Technics, and OEM.

🟤 Header and Turbo Clearance — The redesigned R Mount opens space for aftermarket headers and turbo manifolds.

🟤 Refined L Mount — Cleaner profile, same proven strength carried forward from V1.

🟤 Premium Hardware — Japanese Industrial Standards (JIS) Grade 10.9 flange bolts with genuine Nord-Lock wedge locking washers, the same hardware trusted in aerospace and rocket engines.

🟤 Cerakote Finish — Ceramic based coating originally developed for military use. Resists chips, heat, chemicals, and UV fading well beyond standard powder coat.

🟤 Laser Engraved Markings — Torque specifications and part identification engraved directly into the brackets.

What's New in V2 The R Mount was redesigned to give more clearance for aftermarket headers and turbo manifolds. The L Mount kept its proven strength with a cleaner, more intentional profile.

The AC Compressor Bracket  We included a dedicated bracket in this kit that replaces the OEM unit and seats the K-series compressor in place, with the factory air conditioning system retained.

Engine and Mount Compatibility Designed for the Honda S2000 AP1 and AP2 with a K20A swap. Compatible with any S2000 style engine mount, so you can pair them with Mugen, Spoon, Hardrace, Megan, Vibra-Technics, or OEM mounts depending on the feel you want.

Grid Collection Part of the RBZ Grid Collection. Only 25 units of this design will be produced, each numbered and finished by hand.

Crafted, Not Just Manufactured

At RBZ, we approach every part the way a jeweler approaches their work, with patience, precision, and pride in the detail. Each mount is finished with care, and inspected before it leaves the shop. The TIG welds, the engraved markings, the texture of the Cerakote, all of it is intentional.

Engineering is the foundation of everything we make, but craftsmanship is what gives our parts their character. Each mount kit leaves the Atelier in a custom built wood crate, with every component individually wrapped, labeled, and placed by hand. From the crating to the smallest fastener, the experience is meant to feel considered, not assembled.

We see our work less like a product line and more like a small gallery, pieces built to perform, designed to last, and finished to be admired.

Frequently Asked Questions

What chassis does this fit? Honda S2000 AP1 and AP2 with a K20A swap.

What is the difference between this kit and the K24A version? The mount geometry, bracket placement, and AC compressor bracket are tailored to the K20A's dimensions and accessory layout.

Which engine mounts can I use? Any S2000 style engine mount fits, including Mugen, Spoon, Hardrace, Megan, Vibra-Technics, and OEM Honda S2000 mounts.

What OEM parts do I need to source separately? Two S2000 front engine mounts (50810-S2A-003), one right outer stopper (50815-S2A-013), one left outer stopper (50816-S2A-013), and six 12mm flange nuts (94050-12080). Available from any Honda dealer or OEM parts supplier.

Will I keep my factory air conditioning? Yes. The included AC bracket replaces the OEM unit and lets the K-series AC compressor seat cleanly. Once charged, the factory AC system works as intended.

Does the AC bracket require cutting or drilling? No. It bolts directly to the existing OEM mounting locations on the engine.

What is the 4-point L Mount? The L Mount uses four mounting points instead of two, distributing engine load over a larger area for greater durability under hard driving.

What is the difference between V1 and V2? The R Mount was redesigned for more header and turbo clearance. The L Mount was refined with a cleaner profile. Core engineering remains the same.

Will this work with aftermarket headers and turbo setups? Yes. The R Mount in V2 was redesigned for additional clearance.

What is the Grid Collection? A limited release line focused on refined design and numbered production runs. Only 25 units of this design will be produced.

What makes the hardware different from typical aftermarket? Japanese Industrial Standards (JIS) Grade 10.9 flange bolts with genuine Nord-Lock wedge locking washers. Nord-Lock washers are used in aerospace and rocket engine applications because their wedge geometry holds joints secure under extreme vibration.

Why Cerakote instead of powder coat? Cerakote is a ceramic based coating originally developed for military applications. It is thinner than powder coat but significantly more durable, with better resistance to impact, heat, chemicals, and UV fading.

Are these mounts good for street, track, or both? Both. Pair them with the appropriate engine mount durometer for the feel you want.

Where are these manufactured? Designed, machined, welded, and finished at our Florida Atelier.

How does the kit ship? In a custom built wood crate constructed in-house, with every component individually wrapped, labeled, and placed by hand.
