'93 Honda Accord Aero R
(EX, but shhh…)
It's rough now, but the vision is grand. I want to see the 49 continental United States in this car, so the overall goal for the build is to make it comfortable enough for the long hours on the road, while not compromising enjoyment of any good twisty bits I find along the way. The idea here is all-around balance, I'm not interested in going crazy with power or track-stiff handling.
* Parts in grey are in hand but not yet installed.

- 2.5"-to-3" Vibrant 2630 expansion

Long-term Plans:
- Weld in factory manual trans bracket so I can put a softer mount in there
- "Real" header
- Skunk2 Ultra Street K-series intake manifold w/larger throttle body & intake
- Coil-on-plug
Longer-term Plans:
- Haltech engine management
- Turbocharge to ~300-350 whp, inspired by FK8/FL5; ideally I'd like to find a JRSC or custom-mount a slightly larger roots s/c
TRANSMISSION:
- Manual conversion (starts here)
- M2K4 gearbox (pulled from an H23A1 4WS Prelude; not sure if it's the 4.0 or 4.2 final drive. No LSD.)
- 4th gen Prelude shifter/cable assembly
- Cheddas Auto 4th gen Prelude Delrin shifter bushings (... two of them, anyway.)
- MTEC Industries shift springs
- Speedfactory Racing HD detent springs
- Valex Racing stainless clutch line, master-to-slave
- Exedy Racing Stage 1 clutch

Plans:
- Shorter-geared Prelude trans w/LSD
CHASSIS/SUSPENSION:
- Standard rubber rear and driver-side engine mounts, filled with 3M windshield urethane (pt# 08693, cures to 50-55A durometer)
- Explicit Speed 70A auto-to-manual conversion mount + low-profile rear 'T' bracket
- Explicit Speed traction bar w/torque strut & ABS plate (needed 1" shorter radius rods, sourced from speedwaymotors.com)
- Prothane front sway bar end links, Energy D-bushings, on stock EX 25mm bar
- Tein S.Tech springs on Monroe OESpectrum struts (very much a temporary setup)
- Megan Racing adjustable rear camber arms
- Fat Four Customs rear LCAs & toe arms (here)
- ST Suspensions 21 mm rear sway bar
(* Also thanks to Fleetw00d for a couple odd chassis parts I needed to get the car back on the road)
Plans:
- Decided to stay 4-lug, since the wheels I want are available in 4x114. Will just do front ROH conversion, at least for as long as I'm satisfied with my wheel options. Otherwise, tons of handling and rigidity mods without making the car uncomfortable.
WHEELS & TIRES:
- Rota Circuit 8, Full Royal Sport Bronze, 16x7 +40
- BF Goodrich G-Force Sport Comp-2, 205/50-16
- Photos at stock height here, lowered 2" here
EXTERIOR:
- AeroCatch locking hood pins
- JDM one-piece headlights w/TSX projector retrofit (resto here)
- DIY grille (starts here)
- Coupe/sedan front bumper
- Hella Sharptone 115dB horns
- JDM Si-T turn signals (comparison to stock here)
- JDM sedan front fog lights (install here)
- 3D printed NACA ducts to feed engine air intake
- Spoon-style front lip (on wagon bumper here)
- OEM roof rack (thanks, NH-503P-3!)
- JDM power folding mirrors
- USDM '92-'93 sedan slim[mer] side moldings (here)
- JDM '92-'93 sedan slim side moldings
- EM1 Civic Si "DOHC VTEC" qp decals (had to get black reps, since the silver OEMs were invisible against the paint)
- ViS Racing Evo Style side skirts (these)
- '05-'10 Odyssey rear wiper arm (here)
- JDM DC2R red "H" for tailgate (thanks, tommi!)
- '98-'02 "Accord" emblem
- Custom 3D printed "Aero R" emblems (thanks, Cody Casale!)
- Coupe/sedan rear lip, for its exhaust gap relocation (here)
Plans:
- I would really like wider wheels, which would need a subtle widebody to fit properly (molded metal, not stuck-on flares). Always been a fan of the Evo-style hood on these cars, too, so considering that. And... '90s race livery wrap for fun??
INTERIOR:
- Skunk2 440 gram shift knob
- Circuit Hero shift extender
- Hybrid Racing shift boot collar
- JDM DC2 Integra Type R shift boot
- 5th gen Prelude gauge cluster (might go full custom instead...)
- DIY glovebox gauge cluster: AEM wideband O2, exhaust temp, oil pressure, & fuel pressure (mounted and wired up)
- Garmin DriveSmart 76 navigation
- Kenwood eXcelon DDX396 double-DIN deck
- Kicker ESC65 6.5" speakers, front
- Kicker DSC404 4" speakers, rear roof liner
- Alpine S-S69 6x9" speaker, rear cargo
- Blue carpet swap (temporary? dye black in future and keep? here)
- DIY in-car fuel pump access (here)
Plans:
- I'll be sacrificing some performance here through a bit of added weight, but as stated above I don't want the car wearing me out on long trips. Good sound system, and tons of deadening to get rid of road noise. Recaros, quick-release Mugen wheel. Reupholstery throughout.
WTB:
If you have any of these parts you’re looking to sell, PM me, I’m seriously interested:
- '92-'93 OEM burgundy center console arm rest (condition of arm rest material doesn't matter, but no scratches in the plastic!)
- Sigma side skirts
Progress Log, Highlights:
- 10.xx.2012 // Pulled H22A from previous sedan, junked sedan, began taking my time collecting parts to build up the H
- 01.18.2020 // 286,808 mi // Purchased the wagon, began cosmetic restoration
- 06.15.2020 // H22A build/assembly (starts here)
- 10.26.2020 // Manual conversion (starts here)
- 04.25.2021 // H22 swap (starts here)
- 04.05.2023 // Custom intake & exhaust back from fabrication (starts here)
- 08.14.2023 // Dyno day (here)
