Make sure you pull all my pubes out of the connector that I left for you

Soooooo we're saying the same thing, you just like to argue?

NO! You're old!

Wait... so if the metal gear itself is the same, and its just the bearings which are different... I could just pick up the rx-8 bearings to match the rx-8 eshaft??? I'm thinking pressing in the different bearings would be much cheaper than buying the entire set, IF it would work and that's really the only difference...

Yes?

Nice ECU Levi

[Fendamonky]

Thanks Mike

Now if only I hadn't recently gotten slammed with life expenses that stole all the money I was going to use for building this things harness (and engine)!! lol

[TitaniumTT]

MIDGET!!!!!!!l!!!!

[Fendamonky]

If you two kids don't stop fighting I'm gunna turn this fucking car around!!!....





But seriously, if the gear is the same and the only difference from 7 to 8 is the bearings.... I'm just gunna get 8 bearings and reuse my 7 stat gears.

Does this sound plausible?

There is supposed to be a slight difference in the gear that makes the 8 more suitable for high revs, but they're interchangeable. The whole 8 gear/bearing isn't a whole lot more than the bearing itself. Even closer in price once you factor in having someone press the bearing for you and how many they'll possibly screw up.

The oil passages of the 8 gear do not properly line up with the 7 irons. A little work with a die grinder fixes that issue.

Yeah, the gears are around a hundred dollars more than the bearings. I'm leaning towards the thought of just putting the 8 bearings in because I have the press tool for main bearings and rotor bearings, and my neighbor has a press that I can use.

Since I'm REALLY short on extra money right now (moving and had to hire a lawyer for work related stuff) I'm trying to cut out unnecessary expenses.

Really? I was under the impression that the main alignment issues between 7/8 was from the stat gears to the e-shaft... if the 8 stat gear doesn't line up right with the 7 iron (without modification) than that's one more reason to just swap bearings (unless I'm misunderstanding what you said).



So I got the keg cracked open last night. Well... I got the rear stat gear and the studs out, along with the front stack and stat gear. The rear stat gear didn't want to slide off easily, so I gave it a couple gentle taps with a hammer and block of wood, it came right out.

Both stat gears look good, the bearings are obviously needing replacement, but nothing is spun so far.

I had to stop breaking the engine down last night because the wife was tired/hungry and we had already agreed to grab chinese food for dinner I pulled the rear iron this morning before work, the iron looks great, the rotor looks great. Photobucket is being a bitch right now so I'm having issues uploading pics... I'll dump the pics in when I'm able to get them from my phone to the interwebs..

Welp.... I've got my motor fully stripped. Good news and bad news..

Good news is that both Stat Gears came out fine (new bearings would be good though), and the rear rotor is pristine. My irons look good and the housings seem great as well..

Bad news... the front rotor is pretty fucked up. The rotor bearing walked out about 1/2 an inch and is COMPLETELY thrashed. The rotor tips look like they def made some contact with the center iron (though oddly the center iron doesn't show any corresponding damage). I don't know if that rotor is salvageable or not.. I still need to remove/organize all its seals and clean it up some.

[TitaniumTT]

Rotor is a nice new paperweight.
Send the iron to Chip for some cleanup and grinding/renitrating. The rotor clearly touched SOMETHING. just because you can't see damage, doesn't mean it's not there.
On that note I would throw the front stat gear and front stack in the trash

I'm not trying to go all HC/BDC/JM Imports here... But why trash the front stack as well? They all look just as good as when they went in a few thousand miles ago.

[TitaniumTT]

Because pieces of bearing material went through the entire engine. I wouldn't trust them, and I would definitely be replacing the oil pump.

You want to spin 8500+, make a gazillion hp, all the time and money going into the build, why skimp out on $100 worth of bearings and $150 pump? Sense, it makes none to me. I would also trash the front stat gear because it looks like it got too hot, I wouldn't trust it, I wouldn't use them, but that's me. Lost of people do shady shit and get away with it. I am not one of those people to try to skimp out when spending $10,000 on an engine.
