RS FOCUS
my advice is go to paul hills at engine ad, very clever man an will look after you an your car.
he built mine , i own the 405bhp rs focus for sale and i can assure you no one knows more than he does about those cars (well thats my view anyhow)
dream sci is my advice, easy, safer an very easily mapable on the rollers in comparison to the crap bluefin
And as for front mount kits, you better do your turbo first the pipe work will require the turbo to be spun 180degrees, no point in tarting about with standard turbo uprate it mate thats what i say
paul does kits for the front mounts, reasonably priced as well
