  1. It is very well executed, but it is well executed in an idiom that isn't very appealing to me. Just like the 350Z, albeit a slightly different idiom.

     

    That make any sense? I can never REALLY make a final judgment on a new vehicle until I see one in the flesh anyhow. In any case, the car is very impressive, and hopefully it will take off. (that way in ten years the engines will be ready to stuff in an S30! :2thumbs:)

  2. My car has been completely re wired using a EZwire 12 circuit harness, and everything works like it should on the steering columns combo switches, except when I apply my breaks, my front amber running lights come on.

     

    Until I push on the break pedal, the front turn signals and running lights work correctly. Having the breaks on will not affect the front turn signal lights at all, just the running lights up front.

     

    So... with out any lights turned on, I push pedal and front amber running lights activate.

    With lights turned on, pedal has no effect on front amber lights..... Any idea what this could be?? :hs:

     

    sounds like a confusion in the way the "brake light" circuit and the "running light" circuit are connected as far as wiring for switched power.. I don't know any of the details of how the car is wired, but it should be a simple pair of wires that was installed backwards.

  3. Honestly, outside the Corvettes of recent years, not many new cars get my engine pumping at all. This skyline is another disappointment, but I would call it much LESS of a disappointment than many other vehicles.

     

    The first gen S30 will always, always be one of my favorite body designs, period. I wince when people put skyline tail lights on the things; save that for S130s. Any Z or ZX up to 1987 really really appeals to me much more than anything ELSE Nissan has released since then.

     

    I am still waiting for them to bring back to ORIGINAL Fair Lady, the Roadster. Honda beat them to the punch in 2000, and they still refuse to admit that they could go toe to toe with Miata... and NOW the low-priced roadster market is saturated, between the mazda, the honda, the pontiac, and the saturn..

     

    In the end, whaddaya gonna do? Corvette is the last car that mad much room for improvement, looks wise. Concentrate on the go-boxes; thats all thats important to us anyhow. Like was said above, most of these cars are going to be sold and used as status symbols and NOT dead sexy sports cars. Alas.

  4. I'm trying to go CHEAP, and as painless as possible. I am not an air conditioning addict by any means; I lived through five years in florida without it in the car; I WOULD like to fix it eventually, and I am just trying to get a realistic idea what I am looking at. Rebuilding the compressor thats on there, and replacing some seals, then spending a bunch of money on R12 to recharge it, MAY we be the cheapest way for me to go.. but I am not married to it.

     

    Essentially I was looking to get some discussion going regarding these different ideas..

     

    What I have come away with from this so far, has been that IF I wanted to retrofit an R-134A system, with modern components, into the vehicle, I would have to find the evaporator coil that goes inside the car, and replace the one in the Datsun with one of the same dimensions... That would make the project much more difficult, so I am guessing thats out.

     

    What is so different about the condensors and evaporators for R12 based systems and R-134a? All I have been able to gather is that the condensors for 134a are larger area, because they need it.. but thats hardly any real info.

     

    thanks for the responses!

  5. I live in Lake Worth, Florida.... HOT, HOT, HOT here. R12 is a MUST. You need 3 1/2 cans. Buy them off E-Bay. Will cost you $40 a can. Confirm with the seller that they are full. Don't use Freeze 12 or any other substitutes. OK...now the painfull part ($$$). You need a NEW compressor, a NEW drier, a NEW evaporator with a NEW expansion valve, and a NEW condensor. Also suggest you pull the interior fan and clean it as these old stock fans are feeble and get worse when they are dirty. Also check ALL your vent hoses, making sure they are connected properly under the dash. I strongly suggest you have the system flushed properly by a COMPETENT a/c tech, He'll probably suggest you replace the a/c hoses too. I also suggest you check the BLEND DOOR for proper operation. If it doesn't work right, you'll be mixing warm air with cold and will severly reduce your a/cs cooling. Check to see that you enginge's clutch fan is tight, too. If it all comes together properly, you should get 44 degrees---or LOWER---in our S. Florida heat at cruising speeds. You car's cooling system also needs to be in perfect operating condition to avoiding overheating in traffic.

     

     

    What's to stop me from just getting the condensor, drier, etc from a more modern vehicle, that uses 134A, and retrofitting them onto the car? If I am spending big $$ anyhow, why spend it on stuff thats going to take the (admittedly superior) yet obsolete refrigerant? Seems like everyone in their new cars are happy enough.. am I just THAT ignorant of how much colder R12 is??

  6. I am very close to clueless when I think about bringing the AC back to life in my car.

     

    The car is in "pre-project" stage, meaning i am not doing squat with it right now.. but any time I start thinking about the AC I find that I don't know where to begin. The entire factory system is still there, and i think it even functions (can't recall) and I have a complete spare control console anyhow.. but what I don't know is what I am looking at to try to bring it back to life. Never, in my ownership of the car, has it worked. (since Y2K)

     

    What am I looking at? Rebuild the compressor (I am sure I could do it) or replace with a remanufactured unit? Is the stock componentry even worth messing with, since I don't want to bother with trying to find R-12? Possibly try to find a not-TOO-dissimilar unit off a later model vehicle (using R-134A) from a junkyard? Maybe recon the junkyard condenser, too? What lines might I keep, and what might need to be replaced with newer parts?

     

    I know a LITTLE bit about Auto ACs, and I understand what goes into an air conditioner well.. but I don't have ANY experience whatsoever, and am really rather ignorant on the entire topic. Any help, advice, links or literature is appreciated!

  7. Actually this would be a highly recomended modification. A "Baloney Cut End" is almost required in this case...not so much for the direction of flow (which it would do, especially if you placed the longest point forward, opening to the rear) but for decrease of the pressure where the gasses exit the piping. A baloney cut increases the surface area of the pipe making the flow exiting the pipe to drastically decrease it's speed...it's like discharging into a much larger pipe. It not only decreases exhaust velocity, but it also increases scavenging effects.

     

    I knew it dun' me good when mah pappy dropped me on mah head!:confused2

     

    thanks for the enlightenment as always, and thanks for backing my idea up with more support than I even knew it had!

    I'm not even a huge Star Wars fan (more a Trekkie) but in high school me and my buddy made a game of finding odd phrases to translate into various languages....

     

    Solamente sabes el poder del lado escuro!!!

     

    Wenn du doch nur die macht de dunklen seite kennen wurdest!

     

    If only you knew the power of the Dark Side!

  9. sounds great, I LOVE the Pepsi product placement in the first video :)

     

    might there be room for a small "hood" on the outlet? I am picturing a slight angle cut in a piece of pipe, not enough to form a complete ring but something to be centered on the bit of the pipe most exposed to the engine bay, to "persuade" the exhaust gases to go down under the vehicle rather than anywhere else. Just a thought for possible (possibly un needed, for all I know) improvement.

  10. testing at 28" sucks more!!!!!:mrgreen:

     

    its a difference of pressure, 28" is a full atmosphere or ~14 PSI IIRC.. 25" is a bit less.

     

    i can see there being more pressure, wont that skew the results? it seems that would be like comparing apples to oranges if the #'s are skewed.

    Comparing flow bench numbers for two different heads is comparing apples to oranges. Comparing flow bench numbers from the same head on two BENCHES is comparing apples to oranges.

     

    Flow benches are tools to use in determining the difference made in machine work on one head.

     

    Take head, flow test it, work on it, flow test it again to see if you helped or hurt performance.

     

    Comparing flow test numbers is sketchy to say the least; it is ONE very loose specification on a very complex piece of equipment (the cylinder head.)

  11. I would think that it could be done the way you described but you would almost require labratory type conditions in order to have any real accuracy and repeatability. A lot of people would consider going as far as I described initally as going beyond the point of deminishing returns, I feel that the additional complexity of creating a biased weight for the springs (inner and outer) has truly gone beyond the point of deminishing returns. One of the things to keep in mind about this entire procedure is that it is not creating any power it is only assisting longevity of the parts. As stated in the other thread the time could be used better in other places (as far as creating additional power).

     

    In a nut shell by doing this balancing work you are creating a more fluid interaction of parts which in general will cause the parts to last longer and handle greater extremes but will not create any power that is not already there.

    I fully understood the second part of your post after reading through initially. Regarding the first paragraph, I can only say that *I* wasn't the one who started the "anal retentive," I just joined it because it looked like fun :-P Seriously, though, I also have a tendency to inspect and attend to each detail, on each leaf, of my tree so to speak.. My comments regarding the "technique" were made just to further clarify my own understanding, and educational experience. I didn't expect to hear that it was worth DOING, just pondering how it might be done.

     

    Call it a "What if I was an engineer on a Formula One team?" pipedream if you want.

     

    Thanks again for the explanations, if this thread isn't stickied yet then I am DEFINITELY bookmarking it.
