    Pat deserves the points, I was about to spend $300 instead of a couple $6 cans of penetrating oil and grease. Haha

    mmradix said: I am guessing the coldstart valve is obviously separate but called the 7th injector? Correct. Its a more common name for the cold start injector on a k-jetronic/CIS injection system (called the fifth injector on a 4cyl etc) Apologies for being confusing

    It yes, sometimes it is necessary to reset ecu. I swapped a lightweight flywheel into an e36 and it would hardly idle, reset ecu and it was perfectly smooth again. It has a learning process to adapt to the specific engine. Pretty awesome technology for the time. Sent from my 831C using Tapatalk

    @Brian - The chart is for non-coilover springs. I was trying to show my current non-coilover spring rates (Spax SSX) for comparison. Sorry if I was not clear there. An example I found from someone running slicks on the track for the e28 - 7 inch springs front and rear, 650lb front and 550lb rear with Koni race single adjustable shocks.

    24v swaps are boring. Get creative! [image: Scott\_Bove\_944S2\_Race\_Engine\_01113556144] Oh wait, this is reality, not my personal fantasy land. Sorry. Would get some good reactions when you popped the hood, and the transaxle would keep the weight distribution where you want it. Someday, when I have a nice shop and a crap-load of money and free time...

    So far I've checked the fuse, the switch and the rear plug. The fuse is fine as the switch illuminates when I press it. I'm not getting any power at the connector plug to the fan motor, although I'm not certain that is because there isn't power coming from the switch. The defroster fan motor has what appears to be an external resistor and possibly also a circuit breaker attached to the outside of the fan housing. Again, electrical isn't my strong point, so is there a way to test both the resistor and circuit breaker to see if they're working? My assumption at this point is that since they're there, they must ultimately provide power to the fan which may be why I'm not getting power at the plug. My wiring is fully wrapped and fine as far as I can trace it, as this car was in nearly new condition when I bought it a few years ago with all wiring unhacked. Right now my assumption, until proven otherwise, is that I have either a bad resistor, circuit breaker, fan, or a combination of any of the three.

    straight6pwr said: yeah those are good tires. same tread pattern as nokian hakkas, hancook iPike, etc. i always used 185s for the e30 for winter. less overall grip, but helps not getting stuck with the deeper snow. Cool. That's what I want. Just don't need to get stuck. I'll look for some 60's later in the season for summer. Thinking Hankook right now as I've had good luck with them and they're reasonably priced.

    You can try Mueller Motorwerks to see if they have any in stock? I have one and it works pretty well.

    wasnt m3 said: I have a good intake boot from my m roadster laying around if you're in a pinch. I just deleted the traction control stuff (which you should do). Just order an intake boot from a car without asc. I used a bunch of tape and was able to seal it back up enough to get to work in the morning, I'm about to order a new boot and completely forgot about the ASC delete, I was planning on doing it eventually, thanks for reminding me!

    I did this with a previous car I had. Only problem is when you get pulled over and the cop asks about it. My excuse was always "visiting parents". [image: :)]

    They are an excellent bulb! I had them in my e36 and installed a ton of them.

    I don't know how I do it but I have gotten really good at bending lines. You need to just go slow and apply even pressure

    Just looked at mine yesterday while I was putting the engine back in the car. The cable comes from the passenger side floor, runs along the subframe, Y's off at the starter, continues along the subframe to the driver's side, and snakes up to the alternator inside of the exhaust. Hope that helps. Sorry, I couldn't get a decent picture.

    another idea for a floor lamp that i read as a DIY once. (never made one myself since I dont have a garage).  buy a 4' double fluorescent ceiling fixture (one with a plastic cover) flip it upside down and attach casters, and wire it to a plug instead of a wall box. crap ton of light, and bulbs are cheap to replace and last forever.
