Great to see a 12a. , this one is definitely a mix match of parts . 12a turbo front n rear plates , N grey or talll port centre and 6 pt housing. Any who. It's a good base 12a . In the nineties I did an adaptor to allow fc3s inlet to allow the 12a turbo to breathe and have secondary injectors. With scope for another set. I used full stainless thu tubes as dowls to take the pressure off the bolts under torque. With a high temp mastic sealant on the bolts shaft to stop harmonic s . Later versions we went custom fc3s plates and cut down housing s. This gave bigger ports , braced centre plate, bigger oil pump and exhaust ports.
Love the brap,12a, and 13b. I'm looking forward to this series. I really enjoyed 200% the series of videos about what mazdatrix did with experimenting rotors. Kyle keeps on braping, and thanks for all the cool info
