Hi guys

I have a r32 gtr and am having problems with the car not being able to rev or produce power intermitedly. The car will run fine all good then the exhaust temp light comes on and the car will only idle and sometimes die. If i turn the car off then start it again sometimes the problem fixes and the car will run fine for 15mins then the prob comes back. The car has been progresivly getting worse, Im hoping its a just a sensor that needs replacing. The car has a power fc big single with all supporting mods etc

Just wondering if anyone has had a problem like this before?

any help suggestions would be really appreciated

cheers

Brendan

sounds like you might have a collapsed cat converter. try checking that :(

My EGT sensor regularly earths on the chassis causing the light to come on. - It was being stubborn when I 'replaced' the cat, so just cut it and poked it inside cabin til i can be bothered with it. I'm running a power fc but haven't had any engine opertaion issues.

The cat temp sensor indicator is just thermal switch in the cat housing, hooked up to an idiot light on the dash.. doesn't affect the operation of the engine at all. So, if operation is being affected, it would be good to assume that the cat is overheating, ie blocked..

I had this prob with my r32 rb20det, it started after my fuel filter on my pump got blocked.(someone sealed the pump in with sillicone and it melted into the tank) When the cat light came on and id try to accelreate and it would die. turnd it off, then started it again and it was fine for ages!! if i kept the fuel filter clean it would be fine so put it down to the engine leaning out from starvation and running hoter.

and i also had a hi flo cat and i thort maybe the sensor was in a different spot than standard causing it to heat up differently. I dunno. my sorta came good after cleanen the pump filter!

hey guys thanks for the replys

Drifta1600 sounds like a similar prob to what you had so ill def check it out.

The car has been outside now for 45mins at idle with no probs so ill take it out for a spin tonight see if i get any diferent readings on the sensor check on the power fc. Im off overseas for a week on thursday so might have to wait till then!!

cheers

      Never ending fuel pump drama

      By cabramatta 路 Posted

      Might piggy back off this thread since there's been a good discussion about PWM.   I purchased a Walbro 460 F90000267 and have been looking into PWM to understand it. It was purchased more of a future proof as my original OEM fuel pump died (r33 below 200kw) and figured I'd just upgrade it to this. That's when it hit me that a pump this big can cause more dramas with such high amperage draw and heating of the fuel pump being on 100% all the time in such a mild setup.   I have a Nexus R3 and slowly collecting power mods but I was looking into the PWM feature on the NSP software:   Then looking at the graph from the fuel pump:     Am I safe to assume reducing duty cycle to 50% for example would make the pump run like a 230/lph ? Where does the PWM come in all of this ?   I've gone down the rabbit hole of PWM fuel pumps and it seems there are many differing opinions on how to go about it 馃槄

      Thank you, this will keep me busy for a bit.  I will update progression.

      That specific one would be an exchange part, meaning I'd have to send mine to them. Plus it looks like a non AWD sump, which won't work for me. There is one or two shops in my country that I can ask to do a sump extension job and it'd most likely end up being cheaper than sending mine to AUS or NZ and getting one back, and quicker too.

      Rear turbo is leaky, most likely at the oil drain. From what I could see with my boroscope it seemed to have seeped out at the very top of that return hose. Is it possible that the oil climbs up that hose to then leak out? Yup, coolant leak on the hot side of the engine, only noticed after seeing clear rusty residue in the block right from the turbo oil feed downwards to the pan, and red droplets hanging from the pan. No clear sign yet from where it comes, and most of the lines there are hardlines right? Last year, seeing those red drops, I thought it was power steering, will be glad if that is not leaky at least. Another leaking hose I found by chance is the lower of the two heater core hoses coming from the firewall to the back of the head. That one is not too bad to get to if I have to replace.

      I think for response I'm already kind of out there no? he -5s are not the best pick for that as the Internet tells me. Maybe I should switch to -7s while I still can? Though that almost definitely warrants an engine pull along with the other issues I have.
