So got the motor in the basement and mounted.
Removed the oil pan and pick up, spend an hour removing all the silicone.
Got the front bolt loose only took an 8ft pipe on the breaker bar was surprised the shitty mazdatrix weld held up on the flywheel stopper. Did find the termal pellet was replaced but the regulators werent upgraded.
Took the front cover off removed the pump, chain, and everything down to the stationary gear.
Flipped it broke free all of the torsion bolts and removed rear stationary gear only thing left is to crack it open gotta wait til later
I did notice on of the bolts had an old mazda emblem on it is this normal?
Also noticed I am running a N/A rear housing theres no coolant passange to the LIM. I was gonna block them anyway. Is there any other problems with this?
ill post pix later

whats all this about blocking the coolant passage to the LIM on the rear iron? benefits from this? I'm curious to know all the mods done when cracking a motor so I can do what I want on my rebuild and not be tearing down again prematurely.

yo im in the same boat sort of, blew my motor before christmas. Gonna be tearing it down this week, hopefully i wont be lazy and pull it tomarrow.
The mazdatrix rebuild dvd is pretty good, buddy let me borrow it. message me about it i got a link.
in a prior thread, my turbo ate something so yeah, i dont know what to expect in there.
Have you considered doing any porting? something im thinking about but not sure myself due to increasing the financial cost of the whole thing.

Idk if that rotor housing should be used again. Atleast from what ive learned on here. The side housings could and should be lapped. Are you gonna get new rotor bearings? Ive heard Some guys dont like to do that for some reason.

I've heard that if you see bronze (I think its copper) that the bearings should be replaced. I'll do some searching and make sure I'm right in a bit. others chime in.
I also know that people don't like to replace those bearings because they think it is easier to get a spun bearing due to the force used to push a new bearing in removing some rotor material so its not as tight as OEM. not sure if this is documented or just rumor though.

yeah Im gonna replace all the bearings in it. and probly the rear housing with a tII then send them to goopy for resurfacing. Anyone know where to get lapping done in the tristate area? I know its ported but would still like to go over them with some sort of template any recommondations?

Wont resurfacing affect clearance in the apex seals? Also it may be best to to have both rotor housing on even playing ground so to speak. Idk if you were planning on going with a new t2 housing or a used one in good shape. whatever the case its best to have housings in equal shape. Depending on what parts are reused time bombs can be built rather than a strong longer lasting engine.

The wear on the housings look characteristic of RA seals. Seal tip breakage looks like a standard detonation ping at the weakest point. The porting on the irons looks pretty good. Since goopy is close to you see what they charge to resurface both housings.
