Custom Intake manifold! - Page 2 - Toyota Yaris Forums

Ok, found some info on the 1ZZ.

* 87.5 mm cylinder spacing.
* 41 x 413 mm runners

I measured the flange on the manifold and found that the runner spacing is also 87.5 mm, and the ports are 35 x 52 mm elliptical.

Update:

I found some info on the 1NZ cylinder spacing:

cylinder bore: 75mm
cylinder wall thickness (between bores): 8mm
cylinder pitch: 83mm

That should make the header pitch 83mm as well. Now to figure out the opening dimensions and bolt locations...

Maybe that type of manifold works better for boosted cars than N/A, I had a buddy of mine (with a B.Sc in ME, built an IM as a part of his schools Formula SAE team, and worked for GM) tell me that it's tough to implement properly on N/A cars and a typical runner+log manifold works better.

Well it was stock on the corolla so it must be good enough
