RX8 oil pressure & starting
Discussion
Just bought a 2005 ( 54 ) Mazda RX8 192 in blue, 49,500 miles and paid £2,250 ( mot till April 2013 / tax till December this year ) and it is immaculate, even the wheels, my wife is very happy, lots of browny points.
Just a couple of question's, oil pressure gauge shows half way when driving, probably a silly question, but is that normal, only been used to piston engine's up to this point.
Also when starting, hot or cold, it seems a little lazy, as in it doesn't fire immediately, I hope I am getting this across right, but is this normal.
As I said only been used to piston engines, first ever wankel, any idea's guys.

Hi Stuart,
about half way on both gauges is normal, and the starting - they do sound lazier to start than a piston engine, as long as it does start, both hot and cold, then it sounds fine. It took me a while to get used to holding the key over for that second more than before...
Good luck with your purchase - I've had my 54 plate 231 for 6 years now and loved every moment of driving and owning it

Its either 2 blibs above half or nowhere else its a switch not a guage on the R3 RX8 its just a light that extinguishes
Onl thing i would reccomend is the proper mazda Oil filters as they have the anti drainback filters and this helps get the pressure up quicker than the ones that drain back into the sump

Oil pressure gauge is just a switch as said above so will not fluctuate.
Lazy starter sounds like it may still be on the original starter rather than the Mazda modified faster starter. It was a mod Mazda did when owners complained but I do not believe it was a recall. I pushed for a replacement and it would start within a second thereafter.
Also check coil packs as well as spark plugs - these are considered consumables on the RX8 and the coil packs are recommend to be replaced at 27k/3-year interval. These may also lead to a slow start. If not done, the fuel might not be combusted fully and lead to rotor tips wear and engine rebuilt. When I had mine, it was compression tested every 27k when the plugs comes out to check engine health and it was still very good at 81k.
Lastly, on shortly journeys, read the manual for the shut-down procedure. I remember there was something along the line of opening and keeping the throttle open at 4k while you switch off and pull the key. I think it is something to do with letting the fuel vapour from the cold-start over-fuelling procedure to flush out of the combustion chamber. This is to avoid the engine being flooded on the next start-up.
Hope you enjoy the car, it has one of the best suspension and brakes set up I have ever driven.

Get it remapped and run it on vpower/bp ultimate only. Check the oil every fillup too. I'd consider a full set of poly bushes if you want it to really handle well.
I didn't realise the ECU had been cracked to allow a re-map? The last time I looked it was only Petit racing offering anything close to a remap?Gassing Station | Japanese Chat | Top of Page | What's New | My Stuff
