You COULD run a basic log manifold and go for a GT30R setup, that would get you at your power goal and be easy to purchase online AFAIK. But, I don't know the UK setup/layout. You would be better with a tubular manifold though, a sidewinder can easily be attained, but could be a bit pricey to ship. Would be worth the money though, depending on which you get.

Did you look into any of the ones people suggested earlier in this thread? [MENTION=1228]sstream[/MENTION]
