I have an r33 gts25t. On start up there is a strong smell of unburnt fuel from the exhaust. i have also noticed it sometimes when idling. When I start the car, the smell drifts past the drivers window. The car is starting fine and runs well. I have a Mines Engine Management Computor and am wondering if it is this causing it. I have an air pod and 4" stainless exhaust. Any idea's, comments would be greatly appreciated.

Fuel is definitely coming from the exhaust. When cold it runs so rich u can see grey smoke when its idling. I am wondering whether it could be some sort of cold start mechanism. Does anyone know how or where this could be and how to check it? I dont know whether it is running rich when hot and driving, but cant see smoke when hot. And yes, it is definitely rich smoke not oil. The motor has 60 000 km on it and doesnt use any oil. The engine also runs like a clock and the only miss-fire it has, is at 7000 rpm.

      Nice car! Looking at your GTS; makes me wonder why I bought a GTS-t... Everything has been changed anyway. I should have just started with a non turbo model.

      Rear doors central locking wiring removed and cleaned. See the first 8sec video of when it’s filled with river silt. its a snip of what I’m up against. front and rear doors complete now. Maybe another day removing carpet and bits and pieces. Then the re assembly begins. 🤙 att.DqweJqhY5MZiZYQDVMhn3LtvdD1RBZ7TBG4f2s7W1zM.mp4 att.lFuN22MZEowqCbFAXoDw009r2gHL76ChMVfxMfBX-uk.mp4

      Dual exhaust questions

      By joshuaho96 · Posted

      There aren't boost creep issues, it's not engineered around the restriction of the cats but if you haven't tuned the engine a full decat + exhaust can flow enough air to run off the end of the OEM load scales and you will get a pretty substantial reduction in ignition timing as a result. I recommend using DFCO, avoiding ignition cut limiters, and avoiding popcorn tunes along with running a cat unless you enjoy a perpetually soot-covered and potentially burnt bumper.

      My R32 Money Pit & The Headaches That Come With It

      By 32.det · Posted

      Small update, it's been slow moving over the Christmas period with money having to go everywhere thats not my car 😅. I got myself a little present to myself from "santa" in the form of some tidy radiator mounts from fitmint automotive to get rid of the stock ones that look like they have been in an accident before and then straightened by a caveman. I know I should've replaced the rubber bush at the same time but I had no idea how bad they were until I was replacing the mounts. Decided to order their dash mat while I was at it as I feel like I am lucky enough to have a pretty decent condition dash and I don't want to risk it being ruined while it's parked in the aussie sun while I'm at work. I have found another electrical fault to add to the evergrowing list to eventually chase down. Every time I replace my taillight globe it blows within a day of use, I'm starting to think my life would be easier if I took a few minutes to learn how to use  a multimeter 😂.   Had some luck with finding a series 2 drivers headlight on marketplace to replace my mismatched series 1 headlight, a subtle difference but it's nice to have a matching set of lights now.   I returned to the air con problem due to being sick of this summer heat, found a good condition condenser to replace my leaking one! I got it in the car and was happy when I got the thumbs up that the system was now holding gas. Sadly the compressor is not kicking in for some reason, we even tried branching the relay in the fuse box. I have tried to do some research on the issue with no clear understanding of what the fix is, so for now it will be placed on the backburner until I can be bothered to look into the wiring to the compressor. The last small mods I have done was cutting the horizontal vents out of the front bar, not really in a functional airflow sense but I just think it looks better as I am not a fan of the series 2 bar. I also switched the shift knob out for a hosoboyo aluminium grex style one, it has a really nice more direct driving feel than the outdated rubbery oem one. Thirdly, I chucked on one of the ebay bonnet strut kits. The fitment is decent and they seem to work fairly well. They have only given out once while the car was parked facing downhill, I think if I was working under the bonnet I would still put the oem hood stay up to be precautionary as to avoid getting a speedy concussion.
