I'm getting a Rotrex 'charger fitted next weekend, along with 263 cams. The guy I am buying the 'charger off knows what he is doing and is very kindly fitting it for me and has given me plenty of advice / guidance on what I need. But I just wanted to check for any extra bits I may need or want to get the best from the set up. One thing i'm considering is a Walbro fuel pump. Any ideas of best place to get this and cost? Also, would that need fitting before re-map or does it not matter? Any other ideas / advice would be very much appreciated. Cheers, -Steve
