Indeed. Now there may well be a lot of knowledgeable people on here (more so than me) but my basic advice would be ring the specialist's in their field if you really want definitive answers? When I First considered Forced Induction I rang Vince at Stealth Racing 01926 812259 (Turbo charging) and Dan at TRD (Supercharging) and both where happy to talk to me and give their (actual) honest opinions and advice, which I thought was good of them considering that I wasn't going to use either company..
Worth a phone call. Then atleast you know which way you want to go and what's involved.....
