Okay, what are the top mods for reliability (with proper routine maintenance).

1. SOHN Adapter
2. Premix
3. Access Port
4. Mazmart Water Pump and Thermostat
5. BHR Ignition Kit
6. BHR, Mishi, Koyo, etc Radiator
7. Fluid Fan Control Kit
8. Fluid Oil Cooler fans
9. Aftermarket Coolant Hoses
10. Removing battery tray, etc. to increase flow through the radiator
11. Slits in fender liners to improve flow across oil coolers
12. Oil Filter Relocation

Okay I'm tired, and I missing anything?

 

Premix.

/ducks

 

Can't believe I forgot that.

 

Exhaust bearing.

 

Hilarious.

 

what is also included in the ect. of removing the battery tray, can you remove anything else to help

 

Anyone have a pic of the slits in the fender linings? I'd like to see how people are doing this.

 

1. Take off fender
2. Get a dremel
3. Use dremel and cut slits
4. Put back on fender
5. ????????
6. PROFIT!!!!!

 

i thought you were just "widening" them?

 

^ i saw a DIY on here once for that and i've been looking for like a week and cant seem to find it

 

Not to be much of an ***, but I wonder, if every RX8 owner did everyone of these things themselves (or took it to random mechs) that overall reliability would GO DOWN, due to

1) some of these mods actually being "PERCEIVED reliability mods" and not actually contributing to reliability. Even decreasing it, like the radiators.

2) Fubar'd installs.

3) Unforseen interactions.

I am NOT saying that these things do not have the potential, installed correctly, to increase the longevity of the motor. Just that in the real world, sometimes what you do comes back to bite you in the ***. And on a background of resonably good reliability from the factory, if EVERYONE started messing with these things that things wouldn't start breaking.

Just a thought. Not a slam on the OP.

 

He might be talking about this:

oh, you definitely forgot something.

HIGHER weight oil. ATLEAST w30.

And a wildcard........, synthetic!! (runs for cover)

 

yup that's it

 

I'm so pro...

 

really how is an oil relocation kit going to help reliability?
fan control? the access port does that for you, unless you mean somthing else

wow so just moving the batary you get more coolent flow???? could you elaborate?





oil cooler fans = old motorcycle radiator fans, can be had for cheap....

 

Remove A/C

why? cuz the condenser block like what, 90% of the airflow to the radiator.



but u're in TX so if no A/C I dont think u want to drive the 8 ever again ...

 

sell your car get a crossfire? heheheheh JUST KIDDING


on a side note, when are you getting the BHR kit so we can plan the install meet at my place, hopefully i will have my stuff ready to go by then as well

 

Fixed.

Some of those are questionable, I can't see you gaining any reliability by changing the radiator, especially since the suppliers themselves note that unless you're in a racing environment there isn't anything to be gained from it. Perhaps if you're in the heat in the southwest all the while I suppose or if you track your car, that's it. While I disagree with another post on how they think an aftermarket radiator decreases reliability (it doesn't) it does makes the fins more prone for getting smashed up if something makes it through into them if this ever occurred.

How does relocating the oil filter help? That wouldn't have anything to do with reliability if the original location works fine.

Aftermarket coolant lines? Trivial effects, if any (doubtful)

 

Yeah I know the AP does fan control. As far as the battery tray and other stuff, I just read a couple of threads regarding the removal of all that stuff to increase air flow across the radiator. Oh, and no way I'm removing my AC, been there done that on past track cars.

Jay,

I'm still waiting for it from BHR, no exact ETA yet.

 

^^^

 

Just that this is a professionally built car, manufactured by a real car company. You make it sound like some kind of back yard special.

Why would anyone in their right mind buy a car that needed all that done to it? Or even a fraction of those things?

Ken

 

Ay, if i'd have done the list it would have been:

Heavier weight oil & Premix.

The accessport is a big one too, you could up the oil metering pump, increase gas mileage, and lower fan-on thresholds..

 

Ls7.

 

Just because the car is built by Mazda definitely doesn't mean there is no room for improvement. Manufactures are run the business of making money, not making cars that are perfect.
