Diagnostics
Identify the engine, inspect condition and establish compatibility before recommending a build.
ENGINE-FIRST CUSTOM BUILDS
Review engine identity, electronic injection controls, harness completeness, transmission compatibility and supporting systems before specifying a custom powertrain.

YOUR ENGINE · YOUR PROJECT
Start with the work you want to discuss. We can assess an engine you already own, help source a powertrain, or plan the engine, transmission and controls together.
THE BOMBPROOF APPROACH
We preserve what is serviceable, explain each recommendation and plan the powertrain as a whole.
Identify the engine, inspect condition and establish compatibility before recommending a build.
Review fuel delivery, lubrication and heat management to protect usable components.
Restore mechanical function and address underlying issues before adding performance.
Document the completed system and create a service plan for its actual use.
Match upgrades to a healthy engine, the recipient chassis and realistic project goals.
BEFORE WE SPECIFY PARTS
Share the engine identity or serial number, what you already have, the proposed installation and how you intend to use it. Photos of the engine, harness and transmission help us assess completeness.
Review engine identity, electronic injection controls, harness completeness, transmission compatibility and supporting systems before specifying a custom powertrain.
Transmission, adapters, controls, wiring, cooling, fuel supply, mounts and driveline requirements are reviewed together. Standalone controls are selected for the exact engine and permitted application.
We separate inspection, sourcing, restoration and installation so you can see what is included. Parts availability, project acceptance and schedule follow review.
Review our powertrain sourcing terms and competition project policy. Emissions and use requirements are assessed for the complete installation.
