Hey guys just wanted to get some advice.
I just recently bought a 2005 RX8 with 113,000km on it at an auction and was wondering what you guys think I should be doing/checking on it.
i have been told to change the oil,transmission and differential fluids.
The last oil change that was done on the car says 2018 on the windshield haha.
thanks guys.

Welcome. Start here.
Before You Buy

How does it drive and what's the engine history?

 

The list is pretty long, especially if you don't know the previous history.

 

Well I took it to my mechanic and he said the motor is in really good shape for the year and how many km is on it.
This is what he said ( thing runs and starts like a top) .

Thanks for the reply!!!

 

I am located in london Ontario.
thanks for the reply.

 

That's great news, assuming the mechanic knows rotaries, which is... uncommon. Read and fully understand the site I linked to keep it running like a top. They're not difficult cars, but there are a few things you can't compromise on. Ignition components, cat, spirited driving. It's all explained there.

 

I just bought my first RX8 recently too, I have done the oil change at the dealer, Now running seafoam in oil and fuel (can be a bit risky, but I bought an RX8, I am a risk taker) to hopefully clean some carbon and then switching to Amsoil XL 10w-40 full synthetic engine oil. Amsoil interceptor 2-stroke oil for premixing in the fuel tank. I have changed the transmission oil to Redline MT-90. Differential oil is now Amsoil 75w-90 severe gear oil. Straightened the oil cooler fins. Although my car starts pretty quickly with hot or cold engine, I am getting BHR coils and MSD plug wires. I am going to check the plugs. Battery is new. Next on the list are the following;
1. Decat. I have learned that rotaries were never intended to work with catalytic converters, they are a problem area.
2. high flow custom exhaust manifold as per Team RX8 design.
3. Mishimoto 76C coolant thermostat
4. Oil cooler protection grills.
5. May be fabricate oil cooler fan kit.
6. Lower temp oil cooler thermostats.
7. AEM intake.
8. Replace all coolant hoses.
This is what my car look like right now.

Both bumpers, all fender plastics, front under carriage plastics and oil pan protection tray is off for clean up. Also rear license plate holders fell and are rusted so had to take the rear bumper off to fix the problem.

 

That’s a major overhaul indeed! Lots of TLC.

 

I have not much else to do nowadays. So the scope kept getting broader and broader.

 

I hear you man. If you’ve got the time, by all means.
I wish I had more time to work on mine... gotta resort to weekends only

 

Yea I was thinking of upgrading my ignition system and a few other modes. Do you recommend any?

 

what you mean Neo, you work from home, you got all the time!

 

Looking good buddy I got my safety done and it passed with a minor hvac door switching promblem cost me $300 for the part.
But for the price I picked her up and the sound of the engine and rims it comes with it. I think I got a pretty good deal.
here's a few pics.

Rims and tires that came with it.

 

I wish. I’m still some of the few having to go into work. It’s business as usual where I work. Not sure how much longer though. So many businesses have closed up for a bit... yet, there we are.. slaving away.

 

Same here Neo where do you work and what city?

 

Company is in Newmarket. We make automotive dies so parts such as engine blocks and transmission casings get made.

How about yourself?

 

Oh nice I'm in a factory here in London automotive and we make transmission parts for the big 3.
We have alot of dies and flow forming parts. I'm one of the trades so I gotta be here lol

 

I'm in IT so if someone has an issue with 1 of their computers at their stations, I gotta spring to action...
At the rate I'm seeing things, I don't think we'll be closing down..

 

Always nice to see another person join the local scene, welcome aboard. I'm in Hamilton.

Also in IT here but only need to stop into the office occasionally.

 

I'm thinking of buying a compression tester to see how tip top my engine is.
does anyone know what's a good range they should be at when I do the test?

 

Depends on RPM, so make sure you record that during the test.
Mandatory Compression Test
