I was looking all over the place for templates for the 93, 13b engine, but all i found was intake templates from mazdatrix, does anyone know if there good, and does anyone port the exhaust out, was going to take mine about 1.5mm higher, and smoother,. is that ok >? , I work in a machine shop so milling the rotors to 3mm was no prob, had to grind my own milling cutter to do so though, Noone sells any mm cutters , was also wondering if there was any mods to the engine that would help while it is still apart ?> I would like to build a fairly realiable and fast engine, and while its apart might as well do whateve i can to it.

The Mazdatrix templates are a good streetable profile. They're a bit on the conservative side. RB sells an exhaust template. Again, a good conservative size for street application.

I got my inlet templates from Judge, but got no exhaust templates from him.

Has anyone got sizes for the exhaust side of things??? i.e 2mm higher and 2mm lower..

Looking for aggressive street port to match my inlet.

What type of port were you looking to do? If your not planning on going real crazy and getting a street port you can get those templates all over the place. From people on the forum experienced with porting or from Racing Beat.

I'm looking for a aggresive street porting template, but since the exhaust side is really simple to port I would say you dont need them. Either diamensions or timing marks of the rotors would do.
