There's lots of guys out there that can do the job well and build a proper engine, just off the top of my head besides Pettit and Gotham: Rotary Performance, KDR, Atkins, Pineapple, A-Spec, Yaw, etc... And I'm sure as someone is reading this they're saying "hey, what about XXXX, they're great too..."

BlueRenesis82

oh yeah for sure, those were just the ones I had off the top of my head, no disrepect to any other good rotary shop

What about on in the Bay Area, CA? All I know of is Rick's Rotary (which I trust, but doesn't have a dyno), and Rotary Extreme (which in my mind are kinda questionable, and not sure if they have a dyno either).

Red Devil

Isn't there a Bay Area Rotary Club? You could probably check with them about who they trust, and don't. Isn't Rotary Reliability in that area? I seem to recall hearing about them, but can't remember whether it was positive or negative.

Many of the shops I've named I've never had personal experience with as far as work being performed on my cars. That said, however, I can't recall ever hearing anything bad about any of them, at least from a source I trust.

I don't know if this is relavent, but I work for one of the largest distributors for hydraulic seals in the US......all kinds for all pressures and applications. Anyone have a part number on the seals mentioned about or Specs? Anyone know who the manufacturer is? Seems odd that they can't get a seal.........I can get quotes on tooling of new seals as well.....can a Mantis be curious

Red Devil

You could go to www.mazdatrix.com they sell OEM Apex and Side seals there for the rotary. As far as getting specs on them, I'm not sure where you could find that information.

Sorry to hear about the mishap Sapphonica. This brings me to think about placing aftermarket parts onto my RX-8. I have been reading a lot of different topics on the site and the sheer number of parts available is rather mind-blowing. It’s over whelming on what to decide while taking into consideration not to overkill and damage the one's car. I want to start small… intake, exhaust, suspension, drive-train perhaps. Eventually maybe a turbo or supercharger, but right now it appears only the GReddy Turbo is the only option. However I worry about placing a turbo onto my car fearing that the engine would not last as long, or worse, become another member of the Dead Renesis Club. I will do my research and hopefully I will not have any problems in the future! Thanks to everyone in the RX-8 Club and their views/advice on everything… cheers!

my experience with my RX-7 and the 3mm seals was it runs a LOT rougher

I thought our seals were fine?

Even the old RX-7s seals were fine to 700 whp if you avoided detonation.

guitarjunkie28

if you were running rough with 3mm seals, it wasn't tuned correctly.

rotarygod

I can't blame rough running to the apex seals. I am not a big fan of 3mm seals though. Under certain circumstances yes but not for any street use that I can think of and especially not for naturally aspirated use. Admittedly I do have 3mm seals in my nonturbo RX-7 but it also came with them. It's an '84 GSL-SE 1st gen.

guitarjunkie28

i tend to use whatever i have laying around in my own engine

last time it was 3mm, this time 2mm. next time....well, who knows???

I love a good apex seal conversation although I don't recall what I may have said about the availability of Iannetti seals for the Renesis (Old age is doing a number on my memory). The doctor has been providing renesis ceramic seals for quite some time now. They have been used by Speedsource and I think all the Star Mazda Formula race cars are using them now. I don't know what he has up his sleeve for the turbo applications though. Mazda Competition parts is the main supplier in the United States. It all comes down to tuning in the end which has been pointed out here already.

rotarygod

At Sevenstock Rick had said he didn't think they were available for the Renesis yet. Apparently they are. Cool.

EDIT: I saw pictures of a new Renesis that Rick has right now and a set of brand new in the box Ianetti seals for the Renesis.

BlueRenesis82

Aren't the Ianetti seals stupid expensive?

Red Devil

I think they were going for in excess of $1,500 per set (6). I could be way off, though.

BlueRenesis82

damn. For that price range I would think they are overkill for a street engine.

guitarjunkie28

ianetti's were $300 EACH last time i checked. i dunno if the renesis seals are any cheaper, but @ $1800, i'd say they're a race-only item...unless you're just flat out rich.

rotarygod

I looked back at the pictures again from Rick's shop. The Ianetti seals in the picture are for the 13B not for the Renesis. Even the shape is wrong for the Renesis as the 13B seals are taller. A month ago Rick said he didn't have any Renesis experience yet so this is probably his first one. He may not know of the seal differences between the engines yet if this is true.

guitarjunkie28

i'm gonna have to disagree with myself there... (go figure that out later)

now that i think about it, you're pretty much fuxored if you pop a seal in a renesis--leading to almost every part of the engine having to be replaced. so the $15-1800ish might not be all THAT bad if you're into hardcore mods.

but the above statement i'm still holding to for any peripheral exhaust rotary motor.

BlueRenesis82

but with the side ports arent you fvcked anyway? What would the 3mm seals do?

guitarjunkie28

not 3mm, ceramic.

if you start detonating, you might have a little more time to let off the gas before the seals blow--saving the motor.

BlueRenesis82

so whats the diff between 2mm and 3mm then?

Silverarrow

...oh about... 1 mm

^^ I'm surprised it took 14 minutes for that reply to get posted...

yeah...i was slacking, i had to get out the slide rule to figure it out
