Blew my 83' 12a (pics)
Several weeks ago I blew a couple apex seals on the front rotor of my 83' GSL's stock 12a. I am finally getting around to telling you all the story.
I drove out to mazdatrix to get some suspension parts. I picked up a whole bunch of stuff, boy was i excited. Just after leaving mazdatrix, about two blocks away, I started off in first gear from a red light at probably about 50% throttle and got to about 5000 rpm then.......Bang! the car loses power and falls on it's face. Then is starts to vibrate like hell and feels like I lost like 60% of normal power. So I limp back to mazdatirx so they can check it out. Sure enough I blew something out. They were cool and let me return all the suspension stuff I just bought and then I limped home on the freeway about 15 miles. It actually did okay when you got up to speed, looking back it was pretty funny.
That same night I pulled the engine, and then took it to mazdatrix the next day. I'm going for a rebuild (level "C"), a street port, and a streetport RB Holley carb setup.
I've already begun a long list of things to do and new parts to buy, I be sure to pass on my experiences along the way.
Check out this picture of one of the front rotor's apex seals:

Here's the list so far:
Carter fuel pump
Holley 1-4psi regulator with gauge
new motor mounts
radiator flush
engine compartment cleaning
eliminate crap like cruise control, sub zero system, etc
new pilot bearing
new clutch release bearing
new front trans cover (was leaking a lot)
*clutch is okay
new water pump (cast)
oil temp and pressure gauges
coolant temp gauge
new thermostat
Please feel free to add. This will be a daily driver.

got one of my rotor housings back. Check out the pics.
It looks like I'm gonna be able to take some pictures of my new engine being built / ported next week. I'll post them too.
