I am thinking of having the metal inlet manifold on the 1242 16v ports enlarged.
What benefits would this give and does anyone have an estimation on cost?

BA Dry (no fuel) Plastic manifolds are best as the smoothness inside cannot be better (smoother the better). Dry (no fuel) Metal manifolds can be "port matched" so there is no step however it is not has smooth inside and will have casting edges as they are normally sandwiched together. Wet manifolds (with fuel like the spi arrangment) to my knowledge are all metal and a slight texture is good as this prevents condensation of fuel. In short metal ones you have to port match to remove the step and the texture must be just right, however there is alot of data available regarding shape and the steps aiding charge mix so its all conflicting information really. Chances are your engine has already been port matched anyway. |
