What we do
The Work
Every build is different. Every engine is personal. Here's what ARKoncepts actually does — and what we don't.
Engine Rebuilds
Worn out, blown up, tired, or if you just want to start new— we build rotary engines to factory spec and far beyond. Every apex seal, every bearing, every surface checked.
- —Full disassembly and inspection
- —Porting: Street, Bridge, Peripheral, etc
- —Housing resurfacing
- —Studding
- —Side clearancing, scalloping, rotor lightening, balancing services
Street Builds
Daily-driven rotaries built to last. We don't cut corners on reliability because you want power. Proper cooling, fueling, and tuning for real-world use.
- —Engine builds- stock to performance
- —Custom turbo systems for fast response and desired power goals
- —Supporting modifications including fuel, cooling, ignition, and engine managment
- —Dyno tuning with street verification
Track Builds
Purpose-built for the circuit. — we build cars that are fast and predictable under pressure.
- —Full race motor builds
- —Suspension setup and alignment
- —Race-spec turbo systems for big power
- —Safety equipment fitment
- —Dyno tuning and in person fine adjustment on-track
Fabrication
Purpose-built parts fabrication for rotary platforms that need more than off-the-shelf solutions. Every piece is designed around fitment, function, and the demands of the build. We have an in-house welder and fabricator.
- —Custom intercooler and radiator piping
- —Turbo manifolds and exhaust fabrication
- —Engine and transmission mounts
- —Fuel systems
Engine Management and Wiring
Modern engine management and wiring solutions built around dependable performance, clean integration, and accurate control of every critical system. We work with Haltech, Motec, MaxxECU, and a few others. All our wiring is performed in-house.
- —Standalone ECU installation and configuration
- —Custom engine harnesses and motorsports-grade wiring
- —Base maps for initial startup
- —Sensor installation and calibration
Dyno Services
We have an AWD Mustang Dyno in-house for tuning. We also offer dyno rental services if you want to bring your own tuner.
- —Baseline numbers and power runs
- —Drivability Tuning
- —Dyno rental
Consultation
Not sure what your car needs? We'll tell you the truth. No upselling, no fluff — just an honest assessment of where your build stands and what it takes to get where you want. Or if you are looking to buy a car and are unsure of the existing work, we offer pre-purchase inspection services.
- —In-person or remote
- —Build plan and budget estimate
- —Parts sourcing guidance
- —Pre-purchase inspection
Maintenance & Support
The work does not end when the build leaves the shop. We provide ongoing inspection, maintenance, and support to keep your car performing as intended.
- —Scheduled health checks
- —Fluid changes
- —Diagnostics and troubleshooting
- —Post-build support
ARK Branded Parts
Purpose-built ARK parts developed for rotary owners who want proven fitment, dependable performance, and the same attention to detail we bring to every build.

What we don't do
- Quick turnarounds on neglected cars
- Work on cars we haven't inspected
- Compromise to cut costs or quality
- Price match
We'd rather turn down a job than do it wrong. If your project isn't a fit, we'll tell you straight.
