clio_rsi said:you dont run 3 ecu's mate. if you are, your doing it wrong. you run the 2 volvo ecu's. you need a custom downpipe made up, i just sold mine to dave. custom drivers side mount to take the extra power. clio gearbox for the speedo to work. 16valve fuel pump to cope with the extra fuel delivery thats needed on boost. thats not to mention the custom loom to need to make. so all in all, no its not easy.
i'd say dont even attempt it unless you know what your doing.
