  1. For anyone interested ... like all turbo cars of this era, the amount of boost is determined by the size of the wastgate spring. The 924 turbo uses the same wastegate arrangement as a 930 with a slightly smaller spring (0.8bar if I recall correctly). Boost can also be increased by the use of a boost controller which can be plumbed into the wastegate circuit to adjust wastegate signal to control boost. Usually when the boost controller is installed you also install an air/fuel ratio meter as fueling is very important on boosted cars otherwise you'll get premature detonation. My understanding is that the general rule of thumb is that you can't increase boost on a 924 without also adding an intercooler. I'm currently running at 1bar boost with the above set up. Thing I find most improved is actually that boost comes on earlier as the waste gate doesn't partially open while boost is building due to the boost controller.
  2. I’m green with envy!
  3. When my rear muffler failed I was able to get a new one at the local muffler shop... Probably isn't to OEM specs (which may be important to you and I fully understand if that's the case) however if you're car is more a driver you can probably avoid the $$ of a hand crafted one.
  4. Don't want to high jack the thread however in my attempt to find this particular gremlin I've: - Replaced the DME twice (more original spare was a little old so thought perhaps....) - Replaced the coil - Replaced the ignition key switch (these can tend to crack and cause intermittent stopping ... mine wasn't cracked ... didn't stop intermittent stopping) - Removed the relay board and check for loose wires etc behind. - Checked wire tension around fuel pump. - Did some fault finding during one stop. In short the fuel relay is not getting its trigger signal. This comes from the coil . My suspicion is that my digital ignition controller (or sensor (which are NLA)) may be the cause. Reading suggest that if it's a ignition problem I won't see the tacho move when trying to start car. Today I killed the fuel and tried starting and indeed there is a small bounce. Grand plan is to go out driving again and wait for it to stop and see if it still bounces when the car won't start. Challenge is that I can drive the car all day and it won't fail once ... then the next day I drive it and it stops a couple of times in the hour. Sometimes it stops and takes a few minutes to fix itself .. other times it will restart while rolling to a stop. This thread has suggested I need to reduce my focus on this and instead work on installing some cupholders ... Jason seems to have thrown down the gauntlet .
  5. Sorry Jason @Jason E, it just my insecurities coming through. As a 996.1 owner, those of you with fancy wancy series two cars and associated cup holders just put me on the defensive.
  6. My 2c. I've owned a couple of Pcars now and have come to the conclusion that the 924 turbo is the most difficult Porsche to own. Why? Relatively technical car, with technology that most people don't understand. Near impossible to find a mechanic who has any idea about them. Some parts are difficult (or impossible) to find ... unlike other classic Pcars, the 924 revival is on a slow burn (seems to be happening though) so there's not the same support that's available for 911 etc. Other possible contender would be the 928 .. suspect 924 turbo would pip it though. These cars are now at the age where essentially everything needs to be replaced. The weird parts that I've had to replace during my ownership has certainly allowed me to bond with the car. Just in the last few weeks my radiator cooling fan has started to squeal ... not a big job however will probably require a part to be purchased from OS. The positives - if you get one, you will have one of the rarest Pcars around. I'm a car spotter and I can't recall the last 924 I saw out in the wild. The 924T provides lots of rare 1980 performance car fun. Even though they will require maintenance mine hasn't tended to break down where I've had to walk. Last little while it has as it's developed a strange fault where it runs perfectly for days .. then just stops (few times in the middle of a busy intersection). Wait a few minutes and it works fine again .... welcome to the world of classic car ownership. My only recommendation is that you should only buy the Pcar that really floats your boat. If you truly want a 911 ... don't get a transaxle. Considering the amount of love you'll need to give, you might as well buy something that stirs your heart. If that is a 924/944 I'll welcome you to this very exclusive (prestige increased greatly after Jason left) Pcar club. If you are just keen to get a cheaper Porsche to enjoy some driving in the hills, I'd buy a Boxster. Great little cars, faster, easier to live with and a low risk passage into Pcars.
  7. I chased a cold start problem for ages ... ended up being a loosish connection on my coil. Frustrating yet very satisfying when you score a win.
  8. Looks like I need to ring Shannons and up my valuation. Didn't realise these 924s were such a good investment. Only took 22 years to get a return (if I don't count my receipts too accurately) .

    Coolant leak.

    If I was doing the gasket, I'd probably do the water pump while I was there. Changed out a water pump on a Camry on the weekend. Third pump, car kms 145k.
  10. Just paid my 924's annual insurance with Shannon. For the first time that I recall, they increased the valuation without any prompting from me. If it keeps going like this, soon it will be worth as much as my recent engine rebuild! 🤑
  11. I can't disagree with that statement.
  12. I must admit I chuckled to myself when I used the word 'greatest'... however I was having some fun. I do believe that the 996.1 GT3 was one of the most (if not the most) important 911 produced in the water cooled era. If it had failed, I'm not sure we would now have the generous range of enthusiast models that abound today.
  13. The reason the 996.1 GT3 is the greatest GT3 of them all, is the fact it managed to get made. It went against the grain of Porsche HQ thinking at the time ... the financial boffins didn't want it, the business was concerned about it tarnishing Porsche's brand. However the little 911 made up of bits from the parts bin was so successful that it provided a platform for all the GT3s that followed it. It was the engineering team's last stand ... if they'd dropped the ball the takeover of Porsche by sensible people would have been complete! The GT3 allowed them to fight back (along with the turbo which was also lucky to get an outing) and continue to build 911s with a strong sports car focus.
