Re: Catalytic Converter Thefts.

you are correct a 'decat' should be no catalyst at all probably the seller getting confused I'd say and on the subject of MOT's and the requirement for a cat - I don't think you have to have one fitted as long as the car passes the MOT emissions test required for its year now obviously its a bit dif...

Re: What have you done to your RX-8 today????

If it helps with the decision, you might be interested to hear that there's been mixed reviews for the mishimoto Rx8 radiator and fans. The kit is really designed for drifting, where fans have to be running all the time because the cars are running engines flat-out but aren't travelling "forwards",...

Re: Paul's RX-5

thing is the forces you can apply by hand are tiny compared to the gear separation loads so it may feel fine spinning by hand by unless you can load it up you won't spot any roughness

Re: Catalytic Converter Thefts.

thing is would your average lowlife spot that your cat or decat wasn't an original Mazda unit and then leave you alone?

probably not , 'its an RX8 its got a cat worth £500 I'm having that' I suspect is the level of thought process here

Re: Newbie Looking for a RX8

I'd agree that a compression test should be the next step and its a indication of engine wear but not no guarantee of how long it will last that said if it has compression in the 5's then this should be used as a bargaining tool to reduce the price or shop elswhere if its in the mid 6's to 7's buy i...

Re: Exhaust paint

In my experience none of the paints that you can apply on a DIY basis will stay on any length of time
the professionally applied ceramics are very good but not exactly cheap

as the system is stainless I'd say you're best off just polishing it up with some scotchbrite

Re: Scott's 5.7 ltr v8 ( rxv8 )

nicked and then what?

seems a strange car to steal to be honest
not because its not desirable its just a very select type of buyer

possibly stolen to order
I wonder where its ended up? Romania?

Re: Paul's RX-5

oh dear....
I thought the mixi diff was more or less the same unit as the rexi one?
will a rexi diff fit?

might be worth dropping the oil out and let it strain through some paper towel as it drains to catch any debris

Re: Low compression and high fuel consumption

P0336 indicates an issue with the crank sensor

try cleaning it 1st as it collects all sorts of metal debris as its magnetic

if you choose to remove it then be warned its all too easy to snap the mounting lug on the engine

Re: DIY tuning/remapping with mazdaEdit and Openport

thanks for this Carl I'm presuming the closed loop table you edit to change the closed loop target then are the Closed loop fuel correction A & B where the table is is a percentage? so this is a factor of 14.7 then ? and I get what you're saying that of course any loss of torque can end up with the ...

Re: DIY tuning/remapping with mazdaEdit and Openport

Well trying to be a bit keen really as reading up on some old technical papers rotarys are very mixture tolerant in terms of misfire so wondered if i could pull back the cruise AFR to 15.5 or something similar to save a little fuel

so then gents a couple of mazda edit questions why is the ECT ( engine coolant temp) fuel correction flat in the map ?

Re: Low compression and high fuel consumption

If the coolant isn't dropping then great

next step is to fix the overheating
then worry about the fuel consumption

1st fit a thermostat
then do a compression test and possibly replace the plugs at the same time

let us know how you get on

Re: Low compression and high fuel consumption

Using coolant means the level in the header / radiator tank will drop over time / miles

if this is true 1st check you have no weeping hose joints , signs of damp on the engine or under the engine

if you don't then its an internal issue with a failed seal

and please fit a thermostat

OK this image may help as to why you should never just remove the thermostat ( on most engines) thermostat Dual Poppet.jpg as you can see if the stat is not there at all then you will be losing some flow from the pump back down the bypass, instead of going through the rad if you don't have one then ...
