  1. Installed the Turbo RMS on my 2007 997.1 RS. It has not leaked a drop since doing so.
  2. Keep in mind that the oem GT3 LSD really is poor quality - both in materials and in preload values. Most GT3 differentials, when pulled apart, are barely making contact between the plates (no, or very low preload left), so in essence, they act like an open differential. Guard can get you up to speed far better than I can, but jack your car's rear end up, and see if the opposite side wheel turns when you turn one side. Many forum members who pay close attention to this have said there is no proper differential action when they do this test on their cars. I had an entire set of Guard 60/40 guts installed in my oem LSD housing (parts = approx $1800), and the car seems far less skittish upon corner entry. I don't race or track my RS, so I am wasting much of the advantages of a properly working LSD, but I have the comfort of knowing that it is properly functioning.
  3. Yes, the smoking upon cold start up is usually accompanied by a large puff of blue smoke. Leaves immediately, but part of the engine design. The noise is part of the LWFW charm - just wait until you install Cup Cables - they will really increase the racket inside the cabin!! The Turbo RMS worked great for my 2007 997.1 RS, and stopped the PITA dripping on my garage floor. The techs I have spoken with (all very qualified to speak on this) say the loss of hp is ludicrous, and one has actually dynoed both seals - no difference.
  4. I recently had the trans out of my 2007 RS for 997.2 RS updating. In the process, I had the RMS replaced with the turbo model RMS. No more leaks for the first time in the 5 to 6 years I have owned the car. Problem solved.
  5. Ended up installing a pair of behind-the-seat-in-the-well form fit subwoofer bodies, and a pair of Focals for the rear speakers (from the factory they are left unfilled in the RS). Done now. Unless I upgrade the head unit again. And maybe add a rear view camera.
  6. Make sure you use a larger wrench to hold the welded-on flats where the drain plug on the oil tank is located. You do not want to over-stress the fitting by torquing on it without the other wrench countering this torque. Do this both for loosening and retightening the drain plug. Also, use new sealing washers on both the oil tank and the crankcase drain plug. I also use a clean paper towel to wipe out the interior of the oil filter cartridge holder, as well as the cap. Take some time and inspect the filter cartridge for metal filings.
  7. Something is obviously screwy there, mine is perfect through that range. Time for some in depth diagnostics. Good luck.
  8. I changed to Michelin Pilot Super Sports on my 997.1 RS, and have driven in the rain on them. They felt just fine, with no indication of slipping around. I didn't push them, but I didn't tip-toe around either. Great tire, but being that it doesn't carry the N-spec, your Porsche dealer either won't mount them, or will require you to sign a liability waiver as mine did.
  9. I agree with the suggestion to sell your car and buy a GT3. Far better economics in the future, and the car is amazing in comparison to your C2. I made a similar decision, and have never regretted it for a minute.
  10. My guess is also the plugs or coil packs.

    I have a 2007 RS, and the LWFW does rattle a bit, and it doesn't pull away from a dead stop quite as easily as the heavier unit on non-RS cars. The idle is a little rough, but not horribly so. Snowboarder, I hope to someday emulate you with a 3.9 conversion of my own. I have read of your experiences, and it seems to be a great - if very expensive - mod.
  12. How involved was the roll bar installation. Besides the PITA carpet piece, what is your estimation of the time involved? Is it easy to damage interior items during the install process?
  13. I have a very slight resonance near the dash speaker at about 2800 to 3000 rpm. Very slight, but other than that, quiet as can be.
  14. Nct510, I am in the process of installing RSS rear toe links, rear links (dog bones), lower control arms front & rear, and motor mounts. Did you do the install yourself? Was it very involved? Special tools required? How were the results of your mods? Thanks in advance.
  15. I installed the best Kenwood NAV/Stereo system with a high-quality external amp and 3-way Hertz speakers in the doors/dash. No subwoofer needed as the bass response is more than sufficient. Very satisfied with the system.
