I want to go for the Primary Designs Garret GT28/32 hybrid turbo which is mounted in a slightly differant position to the standard turbo. So with the turbo in a slightly differant position I will require a new manifold. I could however just get a GT28 that would fit the standard manifold but I believe the PD set up that was shown on the April 2005 edition of Performance Ford is the best way to go. The feature was on a guy called Kevin Jones's Focus RS. The performance figures speak for themselves, his 360 BHP car had faster 0-60 and 0-100 times than some of the 400+BHP cars. . But this is just my opinion.
