1.8l exhaust ports

[ozmojo1]

Quick question, are the exhaust ports on a 1.8l BP engine round or oval? Im thinkin of using this on my 2.0 (heard it would work?) but my exhaust gasket has oval ports and im worried about the turbulence that would cause. Here is a pic of it :

it wont fit...might as well get one that fits, im sure there are tons of turbo manifolds for the FS motors.

eh, there are are but damn they are expensive. this one is nice and cheap but im reading allll sorts of bad stuff about obx. oh well.. i will probably end up making my own. thanks

OBX makes good stuff. Bolt the flange up to the head and use a rotory tool to shape the flange to the same shape as the exhaust port.

or get a Mazdaspeed manifold for cheap
