Swipe to see the rebuild.

One of our customers had a bit of a fire on a track day due to downpipe bolts snapping due to heat expansion, that caused a whole big mess. A melted loom & a damaged engine, it was time for a full strip down and rebuild. This list is just a fraction of what has been carried out on this car but we’d be here all day!

• Full strip down and removal of the old engine and everything burnt.

• Replace all Fuel lines, brake lines, vac lines, coolant pipes, brake lines, master cylinder, fuel lines, bushes, ABS Pump & lines.

• Rewire engine loom, bulkhead loom, abs loom.

• Full tunnel & engine bay heat shielding

• Refreshed and fitted meg 250 engine
Painted engine and ancillaries and refreshed steering rack.

• 3” down pipe with link pipe & mapping.
