NIce work, and healthy sounding BP! Rx3 and rx2 owner here, back in the day, stage 2 ported and huge fun. Thanks for the upload, I see Im late in commenting.
Nice, sounds very similar to mine, i have to wait on the transbrake for a while to to build up boost, prob not as long as you tho, what boost did u let the button go? Also what converter do you have? Is it a JATCO box?
A real MAZDA comp tester. Im impressed. I´ve been following your videos, and notices over the years you first had a 12a with low comp (40psi) and then this engine. Please tell me, the low comp 12a, is the one you are push-starting in a video? And this other engine, starts fine with around 70psi? Thanks a lot, I also have a 12a half bridge
