Are the SP6 manifolds all the same?

[mk1fan]

As title, for example do 4.0 Tuscan manifolds fit a 3.6 Tamora?

Cheers.

No some have different lamda size

[TA14]

and Sag spec are a different dia.

[Getsis]

he is on about engine size, they all fit the engine and have the same outlet and position to the cat, only the cat outlet is different on the Tuscan S and Sag. The lambna port if differet can be fixed with an adaptor.

See thread below. It seems that there may have been different diameter manifolds used.
