going to look at some ill but cheap FD today, what could cause turbos overheating ? its car at dealer and they don`t know what to do with it...so they might sell it really cheap

i didn`t saw it yet, but my ideas are :

- clogged cats/some other problem with exhaust (could find out by putting on downpipe/straight pipe ?)

- too lean mixture ? (nonworking one of injectors or they are clogged ?)

- some problem with turbo oil lines ?

what else it could cause ? would see car in couple hours, i`ll try to get pictures and find out more

 

Ill tell ya what it could be...it could be damaging those coolant seals..yum yum


cat issues...intercooler issues....precat...you name it...

its not the small stuff that Id be worried about..its what that small stuff caused that you cannot see that concerns me.

i`ll see more in hour or two, then i`ll get back to ya guys with more questions ;o)
but even with need of engine replacement is car CHEAP

 

When you say "overheating", is the temperature gauge shooting up to HOT? Or is the "add coolant light/buzzer" going off?

 

turbos are getting red

 

My turbo's used to get red when I had a precat. The precat was slightly clogged and the intake was also clogged. The turbo's were getting red because they were working like crazy to make any boost and when they finally got it up there it could not go out. Removed intake and put K&N filters and added downpipe and hi-flow cat and I don't have this problem anymore.

If the motor has coolant issues the turbos might as well. The turbos are water cooler from the engine coolant. If you engine coolant is real low or getting to hot ect... it might cause the turbos to get to hot as well.

Do a motor compression test and a coolant system pressure test to make sure the coolant system doesnt have a leak(the leak might be in the motor)

Make sure when you first crank the car that its been sitting for at least a few hours so its good and cold. Crank it up and see if it smokes white from coolant.

no coolant issues as far as i know...

 

so did you go check it out? what part is glowing? how long does it take to glow? does it glow just idling?

every turbo car has *something* glowing after hard driving...

 

didn`t drive it, had it only like 5 mins started idling...it didn`t get glowing, but it was really easy to feel heat coming from turbos...i don`t know if its good or not...i don`t know too much about FD's yet ;o)

i`ll upload photos in few mins...its sweet car, 1993 probably R1, 139 000 km's on car, about 40 000 km's on motor and turbos - and i could buy it for about $6000, it sits at dealer and they don`t know what to do with it (its not just dealer, its Czech Mazda HQ, importer...)

 

here are photos :

I'd check the blow off valves also-if it doesn't work properly on the y-pipe it will keep the butterfly closed while the turbo is blowing-I've seen this happen(actually someone had taken off this relief valve and lost everything on the highway!

 

i`m waiting on word from dealer, we offered around $6000 for it, if he would say yes, i would buy it and start looking for problems source...i just need to find those $2000 i`m missing ;p

 

in the pics the TACH is from an AUTOMATIC - it may be that the car has been converted to 5spd (or the Inst. Cluster was replaced) if it was a Conversion it may still have the 3:90 rear end insted of the 4:10.

 

its not Automatic, ist original, non-converted manual 5 speed, one of first 1993's, made year around half of 1992, European car, imported in 1992 by Mazda to CZ and sold here...

 

Are you coming with...........FD in Athens,Higgi?

 

Max is correct, the redline in the auto is 7k, 8k in manual. Look at your pic-7k.

 

r1's did not come with a sunroof or wiper either. Sounds like a good price but I'd look it over real careful especially for paint and accident issues. Good luck

 

u guys know specs of european models ? can u list them for me to make it easier to identify car ?
or would tell me more from vin ?

i have absolutely no doubt that car was every second of its life manual 5-speed..

could anyone (who knows european models) tell me more about them and if this is R1 or what ?

 

it has original front and rear spoiler (like R1's had) doesn`t have BOSE subs and does have front strut bar
but it as well has cruise control and sunroof...and probably A/C

 

i suspect that the gauge cluster has been swapped out or your car is just an exception and has the automatic tach face for some reason

here's a picture of a manual non-us cluster. you can see the that the area between 7k and 8k is only half filled with red.

 

The true European spec cars tachs are like that, the picture above is obviously from a RHD car-do not compare that picture-it's either from Japan or UK spec car.Higgi your picture of the tach is how it should be on the European model!

 

Actually the above picture is definetely of a Japan spec car, if you notice the speedometer only reads upto 180km-freaky huh? I have the same one I thought well it says KM/h but maybe it still reads in MP/H-NOPE. I had to replace my original with a used one from a J-spec. I have messed around with quite a few gauges!
