Taking apart fresh Mazda REMAN at Mazmart
 

For your viewing pleasure I am providing images of a tear down of a Mazda manufactured RX-8 6 port engine.

Paul.

Cool

The beginning,

Paul

Looking forward to this - including what happened to the 6-port engine prior to the reman.

Let the horror begin ... lol

I can't wait!

Tearit down!

Travis

I assumed we would keep it PG..

But i mean if we really want to discuss such things..

Break out the fuzzy handcuffs, lets do this.

Travis

never go full rotard ...

This will be educational.

Waiting to see, interested into what they use.
Not that it would matter much, but is this an S1?

Looks like it from the 2 oil injection provisions per housing.

In for the shit show:)

My second bi annual post will be spent subscribing myself to this thread.

Need moar pics... inside, inside! :)

He cant get the front nut off ....common problem !

There's a pill for that...

Long breaker bar make the task lot easier

Everyone will be pleasantly surprised

Curious to see if these things have improved in quality.

insert were waiting gif here

im sure paul could tear this down while drinking his morning coffee lol

I'm guessing he could do it in his sleep but he was probably already working on some other project at that time.

I heard that he only does them in his sleep.

is totally PG :)

Sorta.

C'mon Paul, we need our fix man! 'scratches neck violently'

:)

Travis

I'd appreciate it if the f-bombs would go away. thanks.

nut .... bolt. ........ , potatoe .... potarto . It's all the same

I am pro f bombz

More pics shortly dear friends.

Paul.

Paul, you should be posting this in YouTube live, I pretty sure everyone here will stop what they are doing just to watch it.

The problem is, this is Mr Engman working, and he does not like company while he works. I take these pictures when he's not around. :)

Paul.

More, just for you. friends! :)

Ummm...did those side seals fall out?

What does the dealer and the Mazda reman plant do for cleaning - do they:
1) clean the coolant channels on reused irons
2) clean the SSV and other ports leading to/from engine (mazdaverx8 I think had to do all that himself on his MAzda reman replacement engine)
(3) ...

Ok that's just teasing, we need more than that. Tell the big boss to go to lunch so you can take more. Better yet, buy him lunch, lol

Remans don't come with an intake manifold.

I would imagine 2 of the 3 if not all held against the flat housing by oil when the flat housing was separated from the 'block'.

Paul.

He's actually out of town now and everything is apart for further modification.

Paul.

what mods?

Blurry photos = fubar

You must need a drink :all_cohol

How about a pre-teardown compression test? Maybe doesn't mean much being oiled down though ....

I suck in picture taking. These, nervous shaky hands! :)

Paul.

nice to see you Paul :)

Thanks Zoom.

Paul.

Looks good so far. They have done a good job of cleaning the housing. What we dont know is things like clearances.

My rebuild had a lot of extras such as steel apex seal, billet studs, extra dowels, porting to exhaust, upgraded side seals and may other upgrades.

Its a simple engine and you can spend more money on a bunch of upgrades for little gain.

No housing cleaning. Everything is brand new, as far as housings, rotors and seals.

Paul.

In this group of pictures you can see the used front cover.

Paul.

So Paul, according to sleep-z (employee at reman plant) they did not always use new rotors or housings, he said it was dependent on condition. What have you seen in this regard? My last reman only lasted 24k or so and had a failed coolant seal, Rob at Pineapple said it looked like it happened during assembly.

Contrary to what I've previously read about remans, this one looks pretty skookum.

That policy seems to have changed, maybe about 2 or even more years ago. ALL of their remans have new rotor housings and rotors. Seems to be the case often with flat housings as well.

Paul.

And this is why I bought a reman a few months ago. I believe I read on Banzai's site that they now come with new rotors and housings. I haven't done a compression test on mine (I've got two track weekends on it now) yet, but it seemed awfully nice out of the box. I'll do one this week, though notapreppie's compression tester is highly suspect. :P
