Hi, I am after some guidance/information from anybody who knows what there on with or had experience with.

I have a Mondeo with a 2ltr blacktop Zetec in it and I am getting a little tired of the amount or lack of power it has. I looked into doing a turbo conversion but decided I don’t want to go the turbo route and I don’t have a huge amount of cash for this anyway. After some research I have found that for turbo applications the rover inlet manifold is better that a standard Zetec inlet for air flow so was thinking if it’s better for turbo applications surely it’s better for n/a applications. All the information I can find is to do with turbo conversions not n/a.

Does anybody know if there would be any advantage to using a rover inlet manifold instead as a straight swap (with adapter plates to fit of course) than a Zetec inlet manifold. I purchased a t16 inlet manifold with injection written on the top years ago for a grand total of £3 with throttle body and injectors so would like to use it if its any use. I have seen while my searching that a manifold from a M16 is better than the T16 but don’t know how much better.

Any help/suggestions/tips would be greatly appreciated

 

won't make any difference. Reason they use them for turbo is it can accept cossie style injectors etc.

 

depends on the zetec manifold ur using,its better then the plastic one, but not really on the metal one, it does flow better,

 

On the blacktop engine in a standard installation, the alternator 'clashes' with the #1 runner. On a Focus around 6mm has to be removed (breaking into the runner) and even more to clear a Mondeo alternator (9/98).

It flows better (ref Ian Howell) but mainly at higher revs (shorter runners) so whether you'd get any benefit with the Ford management is debatable.
