All engines will fail based on the fact that they are constantly holding in explosions. Your average piston engine wont see 160k average rotary engine wont see 120k. With that said I rebuilt my 124k engine and am expecting it to last another 40 to 50k on the same internals.

With proper premixing you can minimize the effect of the failed design from the series I.

If your running a SC or turbo with W/M you can minimize the downside of FI.

Its all a matter of how you mod and the thought process you put into it.

If you mod becuase its aftermarket and you think your car will go faster (intake, exhaust and no mid pipe, chassis bracing, most upgraded radiators, most pulley kits, the list goes on of non functional parts). Then your just being stupid and silly.

Functional mods.
Tune, Mid pipe, K&N or Green filter panel filter, Lightweight Flywheel, Lightweight exhaust (HKS Hi power, sounds decent, or a TI exhaust), premix, Sohn adapter, BHR ignition, wider tires, Tein Stechs, SS brake lines, new brake pads and resurfacing of the rotors.

That would get you a fun to drive 8, that's reliable and fixes allot of the glitches that the renesis is plagued with. Its expensive but you can find used parts on the forums if you look.

Im sorry let my Rephrase what I said then...

1- Yes all engines will fail, but not because of design failure, its because of what you said, holding in explosions, but you also have to factor heat in there. Heat is one of the main factors (if not the top) for any internal combustion engine failures... A good quality oil will help prevent this as well as regular oil changes with a good oil filter.

With that said there will always be metal on metal contact, even though slim or with a fantastic oil (Royal Purple ) you will get wear and you will slowly but surely lose compression. This goes for any engine...

With that in mind I still stand behind what I said: All Series I engines will fail because of design. I suppose I should add with a chance for it to fail "Prematurely" in there as well...

2- I have yet to see any data behind premixing doing anything to help make a Renesis engine last any longer. Some swear by it, and others dont. Some say this brand of premix is good, other says it is way too strong and is more of a cleaner than a premix. I think its fair to say we all have seen a 04' model go for 90K on the original engine without premixing and other 04' models premixing and still prematurely failing (Go ask 9KRPMrx8). The MSP-16 flash from Mazda has the OMP increase oil but still doesnt fix the design flaw. It will help but it will not fix the flaw.

3- Yes there are alot of aftermarket mods/parts you can get for you RX-8 that will net hardly any hp or even function.

Underdrive pulley nets you nothing except reving faster, it makes you think it gives you hp when it doesnt.

Some exhausts weigh more than stock negating the effects of maybe the +1 hp you get from it.

Most if not all intakes will just give you noise if not hurt your HP (K&N Typhoon). The stock intake is pretty much is good as its going to get, the AEM/MS CAI are pretty much only for sound/look and might give you 1 hp.

upgraded radiators suck for the RX-8 and will actually make your cooling worse. You're better off sticking with the stock Rad or buying BHR's rad that has been proven.

4- Yes all of those will net you some performance and reliabilty...
