13b Turbo Miata W/pics

As far as moving parts, timing components, etc yea they are a great design and its neat how they get the power out of a smaller displacement engine doing so. But they do have their faults also. Ive been in several newer rx8 that have nearly no compression with low miles. Look at how many FD and FC have had an engine replaced by 100k.. hell even mazda has extended warranties on the renesis just to keep customers happy since the motors are failing.

The Renesis did have a flooding problem. You have to warm them up fully when you crank them. Never start them up, then just turn them off. Once in a while, they will flood if you do that.

The FD's suffered from only 2 issues - not enough cooling, and not enough oiling. Again, they needed to be run harder, and the cooling system (oil and coolant) was not adequate for non-wot applications.

thought that was true of all Rotary to let them warm up,before driving hard or cutting it off....i rememeber cutting my FC off to soon and it flooded

my freind had a non turbo 87 fc with 210k dead ass.

Have you ever known someone with one longer than ~50k miles?

I have had quite a few rotarys of all 3 generations with well over 50K. My FD was the worst with 105K on the first motor, and over 100K and still going on the second. UI have had 3 1st gens with well over 200K on them, including 1 that had 285K on it with no major problems. How many Elements have you seen over 150K so far?
As for Honda motors - a friend of mine on this forum has gone through multiple motors in his Civic DX before hitting 100K. They die easily.

Ok NOW THAT was dumb. Honda motors dont die easily or your friend is a complete dumb ass. My CRX had over 350k on it and ran strong as HELL. Every Honda I owned except one was over 200k. And all NEVER a problem. I drained oil out one and ran it DRY, NEVER BLEW. You can fill them up with WATER and they run.

you can do that with any motor and it will run, eventually they will blow up or seize up. they are all made out of the same material.

the rx8 motor is the renesis and it dosent have a flooding problem like the fc fd and fb

Really? It ran for days, I ran my Civic at Road Atlanta with basically no oil. I ran that car for weeks dry of oil. Do it and prove me wrong

My current FC has 230k miles on it, and the last two years the previous owner (friend of mine) has done nothing buy drag/drift in it. I'll be drifting/autocrossing it as well.
I have owned several FC's, one n/a car had 270k on it and was still running. One was a Turbo II And it had about 165k and still ran just fine.
I also have a CRX that i daily that has 308k miles, and it runs awesome.

It's all in how you drive it/maintain it. I hate when people down a car just because they listen to stereotypes.

do it and have proof of it and prove yourself right

Yes.

Actually, the 2004 did. All of them pretty much have that issue. Simple solution - warm them up properly.

You don't seem to understand how motors work. I know of a Civic run without oil. It was shot in a few minutes - not hours, days, or weeks. Oil lubricates and cools the motor. It is even more important than coolant to an engine. Even a Dodge 225 can't run long without oil - about 30 minutes to an hour depending on load. So no, I don't believe you for a second that you were running RA without oil.

Hmmmm interesting
