Full Engine
Builds.
Engine builds and upgrades develop an engine's mechanical configuration alongside the calibration required for its intended use. They are for owners planning a performance build rather than software changes alone. Etuners offers engine development from Smithfield, Western Sydney by appointment; parts, machining, compatibility and the agreed build specification require confirmation.
How are hardware and software engineered together?
Most engine builders hand you a long block and send you elsewhere for tuning. At Etuners Australia, the build and the calibration are one process. We spec every component with the final software strategy in mind — compression ratio, cam selection, fuel system, and turbo sizing are all chosen to work with the tune, not against it.
Every build starts with a consultation on your power target, fuel type, and intended use. From there we machine, assemble, and break in the engine in-house, then complete the package with a full custom dyno calibration. One workshop. One point of accountability.
Build Stages
Every engine is built to a spec, not a template — but most builds fall into one of three tiers.
Reinforced OEM+
Upgraded rods, head studs, and supporting hardware for platforms pushing beyond safe factory limits. Ideal for fast road and weekend track cars.
- Forged connecting rods
- Upgraded head studs
- Uprated fuel system
- Custom calibration included
Fully Forged
Forged pistons and rods with balanced rotating assembly, machined and blueprinted for high-boost applications and sustained abuse.
- Forged pistons & rods
- Balanced rotating assembly
- Machining & blueprinting
- Big turbo ready
Full Race Motor
Complete competition-spec builds — sleeved blocks, ported heads, dry sump options, and endurance-grade components engineered for motorsport.
- Sleeved / sleeve block options
- CNC ported cylinder head
- Endurance-grade internals
- Motorsport oiling solutions
The Process
01 — Consult & Spec
Power target, fuel type, and use case define every component choice.
02 — Machine & Assemble
Precision machining, blueprinting, and clean-room assembly in-house.
03 — Calibrate & Prove
Break-in, full custom dyno calibration, and data-verified handover.
Every build is quoted individually based on platform, condition, and target. Tell us what you're building and we'll spec it with you.
