480hp Kangoo VAN!

Jon’s no stranger to building interesting, powerful stuff.

This time round he brought his track-day Kangoo van to us for tuning.

The engine is a Megane RS bottom end with a Clio 3 RS cylinder head, VVT, 172 cams, G25-660 turbo, Bosch 870cc injectors controlled by an ECU Master black with Renault CAN integration.

By his own admission the handling needs ‘work’ but it’ll be a blast on the straights if nothing else 😁

Just to confirm that we know that have website issues.

Annoyingly , our web host is no longer supplying our SSL certificate and so we must now apply for new ones. Yes, we should have realised it was about to expire :D

Rest assured, if you proceed to the site regardless of the warning it'll continue to work just fine.
