Damn Ernie, really thought you were gonna hit nines,seen your car in a few vids and it sounds awesome.
Lets hope the NRS seals will do it for ya.
Using PTS seals now after breaking my RA seals in two places and destroying my front housing last year.
I heard SCR seals have good results as well like PTS they just warp on det and save the housing/plates and turbo.

To OP. Very nice car. Get that back together and break the 800+hp. How much boost is your turbo good for and are you still on the stock trans?

So now have gone for a larger turbo (T51 KAI) to suit the porting now along with a 4 inch exhaust and this time I will be running an EGT probe, hopefully if I do run into trouble the seals will just warp/bend like PTS claim.
Just been put back together here is my blogsite if you wanna check my progress over the next few weeks

I have had excellent results with the SCR's and didn't get too much time with the PTS seals. Either can save you a good amount of money should something unexpected happen.

Thermal limits for stand 2mm Aktins apex seals???
I thought maybe some of you guys would be interested to see what we found when we tore the engine down. One apex seal failed, one dowel pin broke, cracking of the center iron, along with signs of the rotor contacting the housing.
I thought it was interesting to see the apex seals appear to have reached it thermal limits. The seal is bowed from the lower center out.

Some of you may have misunderstood. The car didn't detonate. It was ran approx. 10% richer than C116. Nothing to do with that either. You have to run a bit richer a/f ratio at 37-40psi range than you do at the 30psi range. Most of you don't need to worry about this, lol..The new engine will have NRS 3mm ceramic seals. Roberto, not saying the car never pinged in its life but thats not why it died this time. As you know when you break because of detonation the tip of the apex seal usually breaks. This motor had 2 warped apex seals and this last one looked like a termite was eating at it, lol. You can tell it was all the heat. No big deal. Rome wasn't built in a day.

Lee,
Hopefully in a couple weeks. I just overnighted new housings, irons, rotors, and stationary gear from Mazdacomp. Ray sent the turbo out today.
