I've never seen a corner seal messed with... that seems like too much work.

You might be confusing the side seals and corner seals .

 

no I see what he is saying, he is talking about recessing the side seal into a notch on each corner seals edge. I dont this there is anything to be gained by this but interesting concept to almost eliminate and chance of blow by regardless of the angle of the side seal

 

Based on a book and forum comments, NRS used to have ceramic corner seals, but they seem to have been discontinued.

Atkins has some special corner seals listed on their website. Dunno if they are better or not.

 

Rule number one in rebuilding a rotary:

1. Use Mazda OEM seals.

kthxbi.

 

Rule #2:

@. Let SARX build it

thank you for your time

 

Hey if a guy is going to mess things up may as well do it ourselfs~!

 

I have messed plenty of **** up myself so I know first hand that it's much less painful than paying someone else to mess it up for you

Although I still think my water/air inter-cooler and sump pump idea has potential

 

I want a mister for my intercooler

 

Shady and I discussed that, there are a few off the shelf options that work out to be cheaper and less hassle than building your own.

I am considering a water/alcohol system from RB racing.

 

Git er done.

 

they had some problems with fitment of the ceramic corner seals. They solved it by having to mill the rotor a little. The corner wasnt moving in and out like it should have been.
I think the notched corner seal has some benefit for a FI application--wish there was more results from this mod. I think the Aussie guys where doing it?
But for the easy win-oem parts baby--except do put taller apex seals in if you are going to FI.

Curious --was there cooling channel mods, oil passageway mods, stationary and bearing mods etc done?

 

did not appear to be any of them

edit: also, and I hate to say this, there was RTV used to hold the Coolant seals in place and that leaked into the coolant channel....it was bad.

 

NICE! bet that stuff is doing wonders floating around in the radiator

 

yeah I think i have to dump all my coolant and start over again. I hate it. that NPG stuff is money.

 

^filter it

 

Yeap, its not like it ever saw any action. just run it through cheesecloth into a clean container with a lid.

 

^yep

 

Coffee filter FTW Do they sell hylomar locally?

 

It is normal for RTV around the bottom of the housings...but not on the coolant o-rings

 

Yeah RTV is used on the "legs" only typically.

 

Rule #3:

Get the previous rules out of your head and pay a proper engine builder with a lifetime of equipment and knowledge to do a better job than you can ever hope to achieve


Rule #4:

Tell OD to can it with the screwball cockamamie ideas cluttering up threads uselessly


.

 

Rule # 4: If your engine rebuild will cost more than the fair market value of your car buy a Porsche.

 

he already has more than that in aftermarket parts alone, backing up an over-investment with an under-investment is the ultimate fail. Particularly since the engine makes or breaks the whole thing. There are some Renesis builders out there putting out engines that still have perfect compression following several seasons of racing, but then you likely can't appreciate the value of something you really have no idea about.

 

For me to appreciate value I need to see value....

Example: Your unicorn glitter pissing engine costs $6,000 which could net you 80,000 miles.

My non-glitter pissing engine costs $2,000 and lasts 40,000 miles.

Lets take the engines to the math machine!!!

Glitter pissing: Two rebuilds @ $12,000 total mileage 160,000.

Non-Glitter pissing: Four rebuilds @ $9,000 total mileage 160,000.

Savings of $3,000 over the course of 10 years (averaging 15k a year).

 

LOL...wish it was that cheap and lasted that long doing what I do
