a compression check will show what the rattling SSV issue is ... as for getting a rebuild:

The bitter taste of poor quality lingers far longer than the initial sweetness of a cheap price.

It's rather laughable that the person recommending that you do it yourself fails to mention his own adventure to fubar land

Rotary Owner

I have seen many try to take on repairs and maintenance haphazardly and in the end most end up angry with a much lighter wallet and then just bitch and blame the car.

Yep you said it right..

been a rotary owner is commitment,love,passion, headaches but you love it sounds like my marriage lol but is so good,. If I was you I would take engine out and if you are organized take engine apart so you know what your going to spend .

thanks for your comment team but if you recall the issue was lazily not checking the tolerance of parts for non-mazda seals...not the quality of assembly itself and the 2nd time around with OEM seals my motor is running great:bootyshak

9krpm, is work is great. We talked about him before on risky rotors. Is chose him over Pettit. But that's my opinion. He's an independent shop I guess u would call it? So u won't find much info on the web unless people mention his name from having them do their build. (Rx7) forum.

9krpmrx8 12-14-2012 08:49 AM

Huh? I didn't ask about him. Some of the stuff he did on your engine build was coo coo IIRC, I hope it works out in the long run. RX7 builders rarely comprehend the Renesis the same way they do the older 13B's. At least that is what I learned when I called around.

Z0oMzo0m 12-14-2012 09:20 AM

SCOTT my bad :-/ i thought it was you that asked on top about how is is work :-/ thats what happens when you wake up and post..

9krpmrx8 12-14-2012 09:21 AM

Yes, drilling extra holes in the E shaft is coo coo.

His work is great, im currently in my break in period, at 600 miles. i was there for the whole assembly of my motor, and it went together very smooth. I was his first rx8 to build. But a rotary is a rotary, this one just uses side exhaust ports.

We did the racing beat port template,
He suggested drilling the Ecc shaft for more oil flow to the bearings. (you would need upgraded oil pressure regulator and a re-balance which should be done anyways.)

as 9KRPM said what he did was coo coo? idk. nothing unusual done here on my motor.

if you u want to call me
or his shop number 772-343-0510 (JR)

Z0oMzo0m 12-14-2012 09:29 AM

Scott, why would you not want to do that? explain to me please?

The Renesis has several detailed changes and not understanding them can be a big difference between a workable engine build and a really good engine build.

This is probably why so many RX-7 "experts" seem to have trouble understanding the Renesis/RX-8.

your right.. im just saying keeping it short. Specs are Specs, tolerances are tolerances. if you have the book or w/e you are using to have these specs the motor will be good.

Because there is no reason to do it and it's unnecessary. Also without proper testing you have no idea how drilling extra holes in the E shaft effects the oiling system or the balance of the rotating assembly.

Z0oMzo0m 12-14-2012 10:54 AM

thats why it gets balanced afterwards and there wont be a problem.

"Because there is no reason to do it and it's unnecessary. Also without proper testing you have no idea how drilling extra holes in the E shaft effects the oiling system.."

so there is no reason for it? but yet you are uncertain of yourself with a statement like that.

If you can tell me WHY i didnt have to drill extra oil passages because....blah blah blah, then we may have a reasonable debate. but to say what you had said.. meghh.

9krpmrx8 12-14-2012 12:00 PM

If it isn't broke don't fix it. A lack of oil to the bearings is not an issue on the Renesis.

I'm gonna check out autozone after I get out of work today to try and find a compression test kit. I appreciate the time, I don't plan on making my engine FUBAR so I'm probably going to bring it to someone who has had a long healthy history of renesis rebuilds.

Rob from Pineapple Racing brought up a good point, recently many of the 'not so professional' rebuild experts that didn't know what they were doing when it came to the renesis were weeded out as the prices of the parts went up and the economy continued to degrade. Most of the dirtbags went out of business. The ones who survived this long appear to me to be the experts. At least those who I've contacted and what I've observed when I talked to them over the phone. I remain optimistic that my engine will be in far better hands with one of these guys as opposed to cracking it open my own - for the time being.

A proper rotary compression test at the dealer would be a wise idea, the $150.00 or so would be worth the peace of mind for a while and if you get poor numbers then you can start planning for real.

Yeah that's probably a better idea. I almost want to get the kit myself though so I can help the locals out who need compression tests. Nobody I know of around here, private owner wise, has one around town. Might be a worthwhile investment once I know what I'm doing with it.

I agree with Rob as his observation is rooted in understanding Capitalism and the free-market.

It's hard to tell who honestly has those skills when it comes this kind of work, the only real basis a prospective customer like myself has to go on is intuition and more importantly the tech's reputation from work they've done in the past. I appreciate your input, rebuilds are a very large task to wrap my mind around with very little room for error/ irresponsible oversight.
