C20XE / C20LET

The Vauxhall/Opel 2.0 16v C20XE ‘Red Top’ and turbocharged C20LET sibling are the engines behind countless UK club-race Astras, Calibras, Novas, Corsas and engine swaps. Tough by design and brilliant to build on, but they reward correctly specced internals when the boost goes up. Pro-Race Engineering can supply Supertech valvetrain (including Vauxhall-specific dual-spring and retainer kits), forged piston kits, performance connecting rods and ARP fasteners for both naturally aspirated C20XE and turbocharged C20LET builds.

For advice on engine-swap fitment, valvetrain combinations or building above 400bhp on C20LET, call our team on 01621 473023 — we’ve built and shipped parts for these motors for over a decade. Lead times vary by item, so confirm availability before ordering.
