Anyone have any experience or more knowledge than what they have on the website about RBs pp housings, also would a stud kit fit on them? Thank Ya

 

You'll probably have to run a custom fuel rail injecting directly into the ports should you choose to not fab up a separate intake to the ports. Well you will have to anyway because they do not include any sort of throttle butterflies or means of fuel delivery. Another good thing to do is use their aluminum front/center/rear housings. mazdatrix claims a total weight of 109lbs for th whole short block
