hey mate ,do you run themo fans on your set up ??as i have a twin turbo rb 30 /25 set up running 488 rwkw and i was running themo fans and driven around wasnt to bad but i soon as i got a red light or went through a drive through temps would clim ..up ..i pulled the themos off and put the standed fan back on ,and didnt have any more troubles with the temp climming.

cheers

I'm not sure exactly what these thermo fans are but I havnt touched the fans so it should be running whatever fan came with the car.

As far as the climate control goes.. if you push the recirculate button, does the hot air stop blowing?

unfortuntely all it does is limit the amount of air. I can still feel the hot air.

there is a sensor that is prone to breaking, its near the windscreen on the inside above the glove box.

when it goes you basically have 2 settings.... 18 (cold) and everything else (hot)

you need to turn it to 18 and then turn it off to get it to stop blowing hot air :ph34r:

I'm still in the process of checking all the sensors but I just tried the system today (raining and all). it blows cold air but the more I drive the car te air gets hotter. regardless if it's on 18 turned off or on.

almost sounds like the 'heater core' tap is stuck on, as well as the cowl door not closing properly, probably the seal is cactus

any thoughts on solutions?

have a search on SAU for heater threads you should find plenty of info on the heater. being a 33 owner I'm not familiar with the 34 BUT if ya stick ya head under the glove box and hit the 'recircualte air' button, you should see a 'rod and lever' arangement mo0ving, thats the cowl door. Same goes 4 the heater cores tap, change the temp and something will move to direct the water flow.

like I said though do a search. I'm sure I've seen full removal guides and all.

had a similar issue in my car, turns out the interior temp sensor was unplugged, in my case it was a r32 and the centre console got removed and the sensonr never got hooked up, if there is no signal the aircon assumes the temp is -44 degrees and pumps in hot air to stop you dying...even if the thing is switched of, this really sucked in QLD in summer and i was so glad when i found such a simple fix!

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.

      Jacks that fit under GTR lips that can reach the subframe?

      By MBS206 · Posted

      For race cars, this is one part where I find having the roll cage bar having gone through a hole in the floor better than the build it up on a ledge inside... The Merc I help on, the main hoop ends are marked on the car, and the jack is marked... Jack goes under a few inches and lifts one whole side of the car up... Removes that fight for long slim jacks for race car duties!   My biggest issue for the daily drivers I work on, is my jacks don't go high enough. The jacks start out on a few blocks, jack it up, then start a second jack under it on more blocks, and then I can get an axle stand under it. My axle stands are presently in use, and are nearly fully extended. The car is sitting with barely more than a cm of clearance to get the wheel off the studs! Sarah's Kluger is the same, as it has an ungodly amount of droop available in the suspension and a distinct lack of good jacking points!

      Happy? Yep, my to do list is getting shorter and shorter. Either this light approaching is the end of the tunnel, or I'm about to be hit by a train... Ha ha ha   Also, Duncan isn't that far out of town that you need to make a multi day drive out of it. 😛
