Tuners : supercharge/turbo

That's more or less it, although yet to see a 'finished' kit from ktec?

BBPT in Essex were also trying a supercharger kit but the company fell through.
 
Monstersport (technical partner to the Renaultsport Twingo R2 rally series) asked me to gauge interest on here for a supercharger kit some time ago but no one was interested so I think they've shelved that idea.
 
Engine Dynamics are also hoping to have a turbo conversation next year

One rose from the ashes of the other, a piece of their kit is being eyed up by one of our members apparently
