Finally someone else with the same problem. Mark, I related perfectly to how you described the problem you feel. It is true that it is a fore-aft feeling on the butt-dyno; to me it feels like it progresses from fore to aft slightly as the acceleration continues. Above or below a certain engine speed, the vibration is gone, but when I accelerate hard, it is definitely present. I also notice some odd high-pitch buzzy noises at highway cruising speeds, but I haven't been able to isolate it to a particular road speed. It just sounds like I'm running on a strip of short-wavelength corrugations in the asphalt. I also notice, after a hard run up a hill, my left rear wheel area has a faint smell of burning rubber.?? Then again, maybe my car is all screwed up and has a ton of problems that all arose at once... However, the only point in my situation that makes me doubt that the driveshaft is all of the problem is that if, at a standstill, in neutral, if I hold the engine at about 2250-2300 rpm, I can feel a distinct vibration. While doing a hard acceleration, I also feel it at approximately the same engine speed. I have also changed the engine mounts, and I thought it changed the characteristics a bit, but it didn't go away. The transmission mounts, guibo and center support bearing are all 1.5 years old, changed in August 2005. All of this makes me think it is either flywheel/clutch related or a combination of both that and the driveshaft (perhaps some of my hard accel runs have twisted it up a bit?). I am very anxious to be rid of the problem; I am sure the extra vibration isn't doing good things for the transmission internals or the differential internals, and in addition, I have noticed my tranny has been getting more unpredictable in shifting. I am screwing up and grinding gears accidentally a bit more frequently because it hasn't been performing as I expect it to. Totally embarrassing. :( I would not be looking forward to changing out either one of them wallet-wise, although it would be a nice excuse to upgrade. :-P I just need to pull the shaft and check it out. Time is what I need though. I'm also fixing up a 1988 Civic for my girlfriend to drive around; I have all parts ready to go for it. It originally needed BOTH new axles (only $106 for BOTH brand new, yes NEW), and a new steering rack ($170!), and of course I will be changing all associated while-you're-in-there parts, but I will be changing several other suspension components as well with new parts. The life of the car-guy, heh.

However, in lieu of further information, I will start with driveshaft. Mark ==================== Attack the tranny or driveshaft first? Why is that a question? Driveshaft is infinitely easier to remove, inspect and repair. Cheaper too. Why would you start anywhere else? Jeff __________________________________________________ Do You Yahoo!? Tired of spam?

The M42 twin-mass is a beast, 28 lbs, so the S14, weight- wise, would still be an improvement, was my thought. There is also some discussion of a single-mass Euro version of the M42 (perhaps M40?) flywheel that I can get no info on... The gear ring is the question...same or different than the M42? I know it's different than the M20, which requires swapping out a bunch of stuff. Also, I understand the pressure plate on the M20 is heavier than the 4 cylinder's, so some weight is gained back there. cheers and thanks for the responses! r/jpg On Apr 13, 2007, at 11:10 PM, Mark Gold wrote: > John, > > Stick with the M20 conversion.

I am not sure how much of a difference this is going to make, as you have always had to report such enhancements to the TU"V and the insurance -- and document that they won't introduce problems. If you don't and are caught, you lose your insurance and can't drive the car. The easiest way to report an enhancement is to provide a certificate documenting it has been tested for the following: - audible noise per 70/157/EWG - emissions per EG 70/220/EWG - top speed per ECE Regulation Nr. 68 - maximum engine power per 80/1269/EWG - adequate brake performance after an increases in power. Any significant, commercial chip tuner will have already been doing this and will continue to do so, so that their customers don't have to have commission someone to do the tests (which is expensive) or worry about installing their products if they don't. The article cites a "General German Automobile Association". I think they mean the ADAC. The last time I checked, they didn't dictate or write German law. I suspect the article is a mangled press release and would treat it as such. I will let you guys know if I come across anything more substantial. -John '96 318is ------------------------------ Date: Sun, 15 Apr 2007 09:13:40 -0400 From: "Matt Bader" <[EMAIL PROTECTED]> To: "'John Firestone'" <[EMAIL PROTECTED]> Cc: <bmwuucdigest@uucdigest.com> Subject: Re: Not great news for German car tuners Message-ID: <[EMAIL PROTECTED]> John, these are German regs you are talking about, correct?

They should all be EU law by now. The numbers I took were from a German document. I didn't notice its German abbreviations -- but apparently Google did. :) > - audible noise per 70/157/EWG > - emissions per EG 70/220/EWG > - top speed per ECE Regulation Nr. 68 > - maximum engine power per 80/1269/EWG > - adequate brake performance after an increases in power. Try substituting 'ECE' or 'EEC' in place of 'EWG', the French and English equivalents. And also 'No.' instead of 'Nr.' which is Germanic, I think. -John '96 318is ------------------------------ Date: Sun, 15 Apr 2007 09:13:40 -0400 From: "Matt Bader" <[EMAIL PROTECTED]> To: <bmwuucdigest@uucdigest.com> Subject: Re: <misc> old Redline MTL Message-ID: <[EMAIL PROTECTED]> The exception would be brake fluid, correct? It always says use brake fluid from a sealed container because brake fluid, by its very nature tends to absorb moisture. So, if you have a half a quart of brake fluid sitting around in an otherwise sealed container, does it become no good?

I asked Dave Granquist, tech at Red Line, about the same thing back in 2004, and he said there's no problem with using "old" fluids either opened or unopened: "I wouldn't be concerned using product that has been on the shelf for a period of time either opened or unopened, the original performance hasn't been affected they are still safe to use."
