c/x16xe exhaust ports & intake plenum designs

[Sirnixalot]

thanks man! but.....what are those for?

[Adam]

For the SAI.
The valve on top of the exhaust manifold blows air into those holes, which then enter the exhaust manifold to heat up the lambda and cat.

[Sirnixalot]

ohh ok... so even the C16xe has these ports?

i guess its not that difficult a shape to mimic

[Adam]

I dont think the c16xe head has them.
But the ports are the same shape afaik.

[stuartp]

im not so sure the ports on a c16xe are the same il check im mine for ya!

Old thread bump I know, does anyone have CAD plans for a X16XE inlet flange?
