Nice





I wonder if the torque value should be changed..

looks like the extremerotaries kit

they do not have the ribbed OEM tension section in the middle... As far as I remember those were an upgrade within Mazda itself as well.

Damn looks like you will finally be able to put 13B rotors in a 12Amotor https://www.nopistons.com/forums/pub...#>/biggrin.png

looks like it'd be a bitch to tilt the center plate when you put the engine together.

I would think so, they should come with a spec I hope.










The High Strength Oversized stud kit eliminates the need for doweling the engine block. All studs act as dowels which massively increases torsionial strength 70%. Rotor housing deflection reduced - increases apex seal life. Less material machined from housings and plates than with doweling, reducing the possibility of cracking. High boost engine expansion reduced. Studs are less prone to stretching under high boost applications. More accurate tensioning of engine. Less chance of bolt breakage. High quality 12-point nuts rated at 180,000 PSI tensile strength. Studs manufactured from 4140 chrome moly, heat treated, centreless ground and black oxided. Engine must be accurately drilled reamed & tapped to give 0.2mm clearance. Note the standard factory manual flywheel cannot be used with the Stud Kit.
I wonder if the front plate needs to be re-threaded with larger diameter?

Does anyone know if there is a kit like this for the 20B ?

Should be the same as any other engine build. The studs probably get installed last, or at least after the center housing is laid on.

Correct. You install them after you got the center housing on. They can be a bitch to get in the first time https://www.nopistons.com/forums/pub...DIR#>/wink.png
