    Just follow the PSE removal instructions here. When you have the mufflers off you will attach the straight pipes directly to the cats. I hope you don't get the flat spot (that some folks have seen) in the mid-range of your hp and torque curve. Let me know if you have questions Yeah, it sounded great. Maybe I can make the next drive. I've been busy looking for a job...
  3. Loren
    No. Just to be safe keep the key out of the ignition.
  4. Loren
    Not sure I understand... we are talking about physically removing the battery cable from the battery. Is that what you are doing?
  5. Loren
    Yes, that is fine. By disconnecting the negative battery lead you are removing the current path.

    Unplug the sensor (Item 3 is the sensor). Remove the two T20 security Torx screws (Item 4). Replace the sensor and tighten screws. Plug electrical connection back in.

    The RUF short shift kit (for 99-01) reduces the throw by either 30%, 40% or 50%. It depends on where you set it.

    If there is a enough interest we will add a Cup Car Section. Thanks!

    Ahh... I think I get it now. I should have remembered what you are doing. I think the issue is the oil level sender - mismatch. The TT has a different oil level sender than the Boxster and Carrera. The Boxster and Carrera read the oil level out of the engine sump and the TT/GT2/GT3 read it out of the oil tank. Hmm... I wonder if their is a different impedance in the TT sensor. Jeff - if you read this perhaps you can ask Peter about this... in the meantime I'll try and do some research.
  10. Loren
    My understanding of the oil measurement was that the timer in the instrument cluster (time since last start) senses how much delay before attempting to read the oil level (the sensor is in the oil tank on TT/GT2/GT3). The car being level is up to the operator. The only level sensing units on the car that I am aware of are for the Litronics/Bi-Xenon headlights. (Except for the cabs where there is rollover sensing). If you know differently please enlighten me...

    I'm not the Boxster guy but if you are talking about item 1 in this diagram then it is: 996 201 221 03

    The B&M short shifter instructions actually have a very good set of instructions with pictures. You can download them here

    I agree that brake fluid should be changed at least every two years and more often if you track the car. This will remove moisture and air from the system that are byproducts of the tremendous heating and cooling that the brakes do during normal operation. This is a easy DIY with a power bleeder (about $40) and about 1 hour of time. I have a DIY instructions for brake and clutch flushing/bleeding in my DIY section here

    I'm not familiar with the Techart Type 1 rear wing but if it is like the TT Aerokit wing then there are 2 cheese head screws on each side that hold the spoiler wing on. The TT uses microencapsulated cheese head screws on each side so if you don't have those be sure and put some Loctite on the threads so they don't vibrate out.

    Do you mean TSB 12/03 6807 Stainless-steel illuminated door entry guard Installation instructions (dated 9/3/03)? ;) ;) I'll email it to you...
  16. Loren
    Since they are down I will post this here for now. If the author requests to remove it... then it will go.

    Since the air pump does run that is a good sign. You could have a vacuum leak so check the hoses and connections first. If that is not it you will need a PST2 or you will get the air pump to run to do the next tests. Check the electric change-over valve: Disconnect the electrical connection to the electric change-over valve and connect a voltmeter to pin 1 (positive) and pin 2 (negative). When the pump runs you should see about 12 volts (battery voltage) there. Also, remove the hose and check for vacuum there. If that appears ok then put everything back and proceed. Check the air change over valve. Remove vacuum hose of air changeover valve. If vacuum is present at the air changeover valve, check air supply from the air pump to the change-over valve to the air supply line to the cylinder heads. Check function of air changeover valve. Basically, if all the valves and circuits are working then you must have a plugged line. 1 - Secondary air injection pump 2 - Air change-over valve 3 - Electric change-over valve 4 - Non-return valve 5 - To the cylinder heads 6 - Vacuum reservoir 7 - To the intake air system

    I beleive it is a T-20 Security Torx. If you can't find it locally, then you can get one here for about $2.20 (LOL -- $10 minimum order).

    :lol: :lol: :lol: Not all of the bay area is cold. I live in Morgan Hill, CA... about 75 miles South of San Francisco. We have had aver 30 days of 100 degree plus weather this year topping out at 106. Trust me... 94 degrees yesterday -- Morgan Hill is not cold.

    This really depends on your driving style. I am also running S03s and I found that cold pressures of 32 front and 36 rear was a good balance for my driving style. You can try different settings until you find what suits your style best. Just stay above 32 psi (cold).

    If you are talking about the lower track arms... GT3, GT2 and Cupcars have adjustable lower track arms (with shims). Regular Carrera, Boxster and TT do not have adjustable lower track arms -- unless you change them out with factory or 3rd party (The Racers Group, Smart Racing Products, etc.) parts.

    I don't know the price of the part -- sorry. The fuel pump on a C4 requires a special tool to remove it and insert it. Plus removing all the lines (top and bottom side) and draining the remaining fuel from the pump and most of the tank. Installation requires a physical alignment of the housing and reconnecting the (5) lines. Once it is in and both fuel and electrical lines are connected (fumes removed via shop exhaust fans) it must be re-calibrated. Calibration requires 12 liters of fuel only to set the sensor so they will need to finish refilling the tank after calibration. In "shop time" I would guess 2-3 hours times their hourly rate.

    Well, I'm not sure what you are after, here are the measurement differences: 295/30/18 Sidewall: 3.4 in Radius: 12.4 in Diameter: 24.7 in Circumference: 77.7 in Revolutions/Mile: 815.0 295/35/18 Sidewall: 3.9 in Radius: 12.9 in Diameter: 25.9 in Circumfrence: 81.2 in Revolutions/Mile: 780.0 Besides the tire being 0.5 inches taller in the sidewall and 1.2 in overall diameter you speedometer error will increase (revs/mile) by 4.5%. So your speedometer would be slow (i.e. speedo reads 60 MPH you are actually traveling 62.7). Perhaps Viken can add some comments?

    You can check out this $125 scan software and cable (if you have a laptop to use)... See this post

    Shims for the track control arm MY04 GT3. 996 341 543 90 Shim 1 mm 996 341 543 91 Shim 2 mm 996 341 543 92 Shim 3 mm 996 341 543 93 Shim 7 mm They all appear to be special order.
