NEW RX7 OWNER Turbo question

[safrx7]

sorry to sound daft but how does the oil temp gauge work
what mark level should it be ready on so i can go for a blast?

[nikp]

I think you\'re referring to the oil pressure gauge. This does not show temp.

Also, be very wary of the water temp gauge, as it only moves once its up to temp when the engine has overheated. You should get an aftermarket gauge or power fc and command.

I think you are mistaking the oil pressure gauge for a temp gauge bud, i would estimate once the water temp reaches say 78oC wait another 5 mins for the oil temp to be sufficent for a blast :Thumbs-up

The standard gauge in the dash is the oil pressure gauge not temp one :Party

As all ready pointed out if you are referring to the Oil temp (aftermarket gauge) and not the stock pressure gauge on the Clocks the best way of telling when its warm is go for a drive for say 30-40 minutes drive carefully on the way back and make a Mental note of where the gauge is, Thats roughly the Position you can say your car is Properly warmed up and you should get it as close to that mark as you can before you Hammer it.

The warm up is one of the Things that stop me fitting an EWP (electric water pump), i had one on my Turbo 2 and it really did slow down the Warm up Procedure.

right i went for a 30 minute drive
 
1. the water temperature reached around 100c is this normal?
2. the thermostat coolant gauge stayed in the middle
3. the gauge above the thermostat with 0, 4 8 with an icon of a little petrol can holder in on kept moving up and down i guess thats the oil pressure.
 
after driving for 15 mins and the water temperature moved to 85c the 2nd turbo kicked in beuatifully with a huge pull.
 
then i took it steady for 10 mins and then i blasted it again but there was no pull in the 2nd turbo after that. the temp was 100c
tried a couple of more times again but still no major g force
 
i just cant get me head around whats going on.

The icon shows a little oil can. (the one that goes down more tha up is the fuel gauge :Santa ).

That second turbo should boost all the time once its warm. There are a lot of little vaccum pipes, solenoid, valves and air tanks that control the Turbos, so its usually one of these small components failing that causes the Turbo to not come on line.  Not so easy for the DIY man to diagnose, though.

[safrx7]

thats what i thought the second turbo has to come and play all the time once its warmed up and not when it chooses to itself.
 
right do u reckon i should get mazda dealers to have look at the
vaccum pipes, solenoid, valves and air tanks for the second turbo problem as i dont know any1 local around here.
 
or r the dealers a waste of time??

[lockwood77]

I would guess WGT in Middlewich, Cheshire is the nearest specialist mate. Mazda dealers don\'t have the best reputation when it comes to rotaries...

[Martiny]

LockWood is right. Mazda dealers see so few RX-7s, they are pretty clueless when it comes to diagnosing the FD Turbo system.

WGT is highly recommended.

anyone got a tel number or a website address
 
i might need to book something in for them bcoz it defo needs cheking out

[safrx7]

any one got a tel number or website address for them

google is your friend...

[safrx7]

booked it in with http://www.wgtautodevelopments.co.uk/ monday at 1.30pm for a diagnostic test on the 2nd turbo and a compression test.
 
hopefully they can find out what problem is and fix at another date.
 
will keep u updated

Wow i just joined the fourms they other day and i have to say ive been after an RX 7 for a long time still in process of saving for my 3rd gen, I have to say this fourms by far have been most helpfull to new comers. I have checked out other fourms and they seam be be like little familys no real room for new people.
 
Back to the point it makes sence about the oil heating up and cooling down, as oils not like water makes sence why it takes longer. Thanks guys learning new stuff all the time.
