I brought first RX-8 in 2005 and my second was a 2009. I traded in for a 2011 the last year made. I sold the 2009 because it was a stick. Thought I would kill my self driving with the power LOL..
So I got 2011. Now 157000 miles later I engine has died. I m heart broke, I have loved my RX-8s and not sure what to due from here.

 

Eh, its just an engine. Get a good replacement and keep on motoring. Granted it might be cheaper to get another used car, but its engine will also have unknown number of miles left in it, so if your intent is to keep driving RX8s, replacing the engine is the best long-term plan. Just make sure everything else is verified and/or fixed at the same time, so the new engine doesn't inherit the old engine's problems.
You can get a replacement through Mazda, Rotary Resurrection, Pettit Racing, and many other rebuilders. Depending on your location, there might be a logical nearby choice.

157000 on the original engine is not bad. Assuming it was original.
Out of curiosity how did it die?

 

engine lost compression, was told crack inside.

 

Mazda dealer. said no compression, crack inside motor.

 

Was this a former drug runners car or did you hide some in the rotor?

 

A Mazda remanufactured rotary engine is actually not super expensive when you compare it to remanufactured piston engines. It's just that with a lot of piston engines, you could just get a used unit instead of rebuilt ones and there is a good chance it will work fine. Not so much with a rotary. You will want to make sure you get a quality rebuilt unit, from the sources Loki mentioned.

While you are in there, you could get the clutch done. It's also a good chance to replace all cooling lines. Overall, you are looking at maybe US$6k if you want someone else to do all the work and also take care the other stuff like clutch and cooling lines I have mentioned.

 

The Mazda Dealer wanted $9100.00 to fix!

 

Either talk to a different dealer, or check that list on the forum that lists all the good indy rotary shops around.

 

. Is it wise to put a new engine into a tired car? I would if it is low mileage but at 157k miles, you have other wear and tear that a new engine will not overcome.

 

Given the car market now, it still might make more sense to fix up the car than to replace it, especially assuming you have some DIY capabilities.
