Mazda builds them correctly but anything could happened in the assembly line. I have taking engines apart with low miles burning coolant. When I tear the original rebuild apart I have found that during assembly by mazda the coolant seals did not seat properly against the rotor housing and side housing. When this happened the coolant seal was crushed and allowed coolant to lean into the combustion chamber. Stuff like this happens back in the assembly line.

Sorry to hear that about your car dude.
Make that 12 sec car happen.

Judge, i see your point with the side seal failure however there is many 13b owners that have ported out to 30%+ and still dont have trouble. I guess the seals see 2 times as much outside the housing than before. Could the seals be flexing enough during shock to be caught in the ports?

The seals are not flexing but the rotor itself could slightly vibrate at high rpms. When the rotor vibrates, the sideseal could crash into the upper edge of the port(closing edge) and create some damage. I'm sure Mazda researched the port closing and has it covered, but when some early engine damage is due to sideseal failure it makes me think. Many engines builders including myself have used double sideseal springs behind the sideseal to try and stabilize the rotor at high rpms from moving side to side. I myself have ported large street ports more then 30% intake opening and had great results, but I payed close attention to the edge where the side seal is introduced back into the side housing.

The brakes rock, the handling is precise and very predictable and it's more comfortable to be in. It doesn't excite me quite as much as driving the FD does, but I enjoy driving it just as much.
So the main reason I'm not critical of the '8 is because I stopped comparing it to the FD, it's not one and I don't expect it to be one. It's a different car and I enjoy driving it as much as the FD but for different reasons.
So there you go.

I had a BMW 328Ci in 2001 that was much faster than the RX8, had superb road feel, very flat and predictable handling, stability control, awesome brakes, and even a back seat (which was very hard to get into and out of).I still like the RX8 better, for different reasons. Here are a few:
Design & Aesthetics
1) Its looks
2) The interior space and layout of same
3) The rear doors
4) The lighting - interior blue on the cluster is so cool, the design of the rear taillights, the front headlights
5) Use of the rotor design element
Sportscar-like issues
1) 50:50 weight distribution
2) Great out of the box handling
3) Excellent road feel and connectedness to the highway
Lots of others as well.

im assuming your beamer was stock velocityred, but correct me if im wrong.
i don't think your 2001 328ci was that much faster than your current rx-8. a 5-spd 2002 330ci pulls about 6 flat according to most publications, the 328i has to be slower, which would put it at about the same pace as the rx-8. also, im fairly sure that your rx-8 could outbrake your beamer even though bmw is famous for their strong, has-to-be-german made brakes. not flaming at all, just some comments i had.

Ito knows what he is talking about....and I think I agree that he just got a bad one from the assembly line....
As soon as I get the funds, Im sending my 89 TII to him for a rebuild..:D
I just want to know how to make my 8 as fast as his....
