Project Cars

We build cars race-ready — from fast-road projects to full track and motorsport builds. When stock limits aren't enough, we go further with Stage 3, Stage 4 and Stage 5 software and hardware.

A project build is hands-on: we plan the spec around your goal, fit and develop the hardware and software together, and validate the result with Insoric performance measurement.

Beyond Stage 1 & 2

Stage 3, 4 & 5 — built for the track

Higher stages aren't just more software — they're hardware builds. Each step adds components and a fully custom calibration developed and measured around them.

03
Fast Road / Track Day

Stage 3

Supporting hardware plus a custom file — a serious step up for spirited road use and track days.

  • Upgraded turbo / intercooler & intake
  • Downpipe & exhaust upgrades
  • Fully custom ECU calibration
Strongroad + track gains
04
Track Focused

Stage 4

A bigger hardware package with engine and fuelling support, calibrated for sustained track use.

  • Larger turbo & uprated fuelling
  • Engine & cooling support
  • Logged, measured calibration
Hightrack performance
05
Full Race Build

Stage 5

A full motorsport build — engine, drivetrain and electronics developed together for maximum, reliable performance.

  • Built engine & drivetrain spec
  • Motorsport electronics & sensors
  • Bespoke calibration & validation

How a project build works

Planned, built and measured

01

Plan the spec

We agree the goal, budget and stage, then plan the hardware and software together.

02

Build & fit

Turbo, fuelling, cooling and supporting parts are fitted in our workshop.

03

Develop the software

A fully custom calibration is developed around the exact hardware on the car.

04

Measure & validate

Insoric performance measurement confirms the result before the car leaves.

Stage 3–5 builds change how the vehicle performs and may affect road approval, MFK, insurance and warranty. We'll advise what's realistic and road-legal for your project, and what's track-only, before any work begins.
