  1. You can also use saw dust just like the kitty litter. The Trak Auto/Home Depot oil dry stuff is the same as kitty litter. Really, as long as you cover the spill and rub it in with your foot as soon as it happens it is not a problem.

     

    For the stains that have been sitting awhile, Tide has trisodium phosphate. Mix up some Tide and a little Colorox in a bucket of water, scrub into the stain, let it sit awhile then either pressure wash or scrub and rinse and they are gone. While your at it, the same mixture makes an excellent deck wash and house siding cleaner. Might as well do the fence while the pressure washer is out.....

  2. *sigh* Are we actually arguing this Corvette vs. BMW crap?

     

    Funny I saw it as two differing points of view trying to reasonably justify their opinions to others... Not sure what the harm is in it. Nobody was getting bent out of shape about it either.

     

    I agree.

  3. About a year ago there was a long thread about the myth of warped rotors. Someone posted a link that says the vibration is not due to warp/bent rotor but an uneven layer of brake pad material built up on the rotor. The link included detailed instruction on how to "bed" in new pads to the rotors to prevent this.

     

    I don't remember what the fix was once the rotors have "warped". Certainly having them turned will get the old material off, but there may be some way to bed in the pads on top of the "warped"rotors.

     

    Try a search, or maybe someone will repost the links.

     

    For your brake fade, replace the brake fluid with some high temp stuff. Then try to rig some type of ducting to keep the front brakes cool.

  4. A test of the battery showed 12.5v with the car off, and 14.65v with the car running.

     

    That tells me everything is working as it should. Is the car still dying since you replaced the alternator and voltage regulator together?

     

    Ampmeters are horribly inaccurate. A voltmeter will tell you much more. But I guess you have enough experience watching amp meters at this point to know if it is telling you something.

     

    A couple of things. You said

     

    as I was pulling into the parking lot at work, the engine died. It started back up, but wouldn't stay running. The battery was dead.

     

    If the battery died while you were running, it would not have had enough juice to crank the motor. Sounds more like a loose connector or intermittent short to ground.

     

    You also said when you replaced the alternator the first time that the "amps were almost all the way to +60". This is extremely bad. Tells me you either had a short some where OR your voltage regulator was bad causing the alternator to put out WAY too much juice. This probably killed the first replacement alternator. You're lucky it didn't fry the battery too.

     

    What you are describing since you replaced the alternator and voltage regularo together sounds about normal. If the 75 Z has the same charging circuit as my 70, then the ampmeter movement sound about right. The external voltage regulators are rather crude and don't regulate the voltage as well as new ones. My ampmeter jumps all over when I run the blinkers or any large accessory. It should sit a little on the plus side when it is not moving around, and a little on the negative side could be nothing or it could mean your alternator quit working.

     

    You know what this could be? Dirty battery posts (or a bad cable). Believe me I have seen it more than once. Pull the battery cables and wire brush both parts, even if they look clean. Then hook up a voltmeter so you can see it as you drive. As long as the voltmeter shows around 14 volts you should be OK.

     

    My worry is you might have some type of intermittent short circuit that is grounding out the altermator causing it to burn up diodes. The problem may have been with your old voltage regulator, but with a 30 year old car you could have a chaffed wire almost anywhere in the car.

     

    Good luck.

  5. This case was a $10000 car vs. a $50000 car, hence the cost was 5X.

     

    Not to be a PITA, but the $10K car was really a $0 car. Being stolen it was worth absolutely nothing. The old saying "if it looks too good to be true.." is certainly illustrated by this story. The idea that an absolutely flawless car could sell for half the average price of comparable cars should have told that guy everything he needs to know.

     

    Now if you want to compare a 3 year old M3 that isn't the product of a chop shop to a 3 year old vette, then you have an apples to apples comparison. New they are both $50K cars.

     

    The Z06 weights in at 3140 pounds. I was a little suprised. That is not that horrible in this day and age. Especially when the 350Z with it's smaller everything comes in around 3500#.

     

    Get the vette, strip off the AC, airbags and leather seats and I bet you could get that thing down to the same weight as most of the 280's on this site. Add a cam and some forced induction.....

  6. This particular M3 is only $10,000.

     

    This particular M3 was also bondo'd together (literally) from 3 stolen M3's. That is why the guy was so quick to overlook all the problems. The car was selling for way under what even run down used M3's sell for.

  7. If you want a vette then why not buy a vette ?

     

    I am not trying to be a smart ass or disrespect anyone, but this is something I struggle with in planning out some of my intended Z car mods. It seems like my list of "if I could only afford it" upgrades makes me wonder if I am just trying to build a vette. At which point I ask why not buy a damaged vette and strip off enough creature comforts to get the weight closer to what a Z with chassis reinforcements will weight.

     

    And don't say "but then it wouldn't be a Z" because at some point grafting Z body panels on a vette chassis says the same thing.

     

    Besides, most of the vette front and rear set ups look like they will add a good bit of weight. I will be very interested when some of the on going projects get complete enough to get on a scale.

  8. Yes, a Z06 would be faster, but at 5 times the cost. :P A McLaren F1 would be faster too.

     

    My neighbor says he will sell me a new Z06 in the $50-$60K range.

     

    According to this site

     

    http://www.rsportscars.com/eng/cars/bmw_m3.asp

     

    a new M3 lists at just under $50K.

     

    Compare the M3 to the Z06 by looking at this site

     

    http://www.z06vette.com/01.php

     

    The M3 is 300 pounds heavier, has 50 less HP (at 7900 RPM!!) and downright skinny tires compared to the vette.

     

    No question which car I would rather have. Of course I probably would not look as cool with the Seattle Starbucks crowd.

  9. My wife is an ebay addict and as such is on a first name basis with the UPS guy.

     

    We have had damaged goods delievered and UPS has always made good. Make sure you save as much of the original package as possible. They do pay the shipper because that is the one they have the contract with. A little scary with an ebay shipment, but sounds like you will have no problems.

  10. We have lost so many posts when we went to the new software.

     

    There was a thread some time back detailing the steps needed to precisely locate the pivot point to eliminate bumpsteer. The only thing I can't remember was the role of "bumpsteer spacers", those MSA spacers that bolt onto the bottom of the strut housing. If I remember right, the spacers really don't correct bumpsteer, but on a lowered car are necessary to retain the correct camber gain curve (whatever that means). The upshot is a lowered car may need both the bumpsteer mod and the spacers.

     

    What I do remember is how to compute the relocation point because the idea makes sense. The idea was to put the car on jack stands and remove the front springs. This allows you to move the front suspension through it's full range of travel. With the front tires removed, connect some type of device that allows you to measure the change in front toe as the spindle in moved up and down. Some guys were doing it with dial indicators, I figured attaching a laser pointer to the brake rotor and tracing the dot along the garage wall would work best. Just move the front spindles up and down while tracing the dot to make a line on the wall.

     

    If you do this for both sides, measuring the distance between the two lines will tell you how much the rotors point in or out as the suspension travels up and down. What you then need to do is, by trial and error, move the lower pivot point in and out, up and down, while redoing the test. Once the lines go up and down the same distance apart, that is where you want to place the new pivot point. I would take a rod the diameter of the control arm bolt and sharpen both ends to a point. This could then be placed in the control arm bushing, and the cross member C clamped against this to hold everything while the test is being done.

     

    Theoretically, JTR did just this when then came up with their "7/8 up, 1/4 out" (or what ever the exact numbers were). I would think that once it is figured out for one Z, then it should be true for all Z's.

     

    BTW, the thread also said Datsun purposely mislocated the pivot point to try and compensate for all the rubber isolators they put in the front end.

  11. Maryland puts non OBDII cars on treadmills and runs them at speed. I could see that triggering boost. OBDII cars only get the error codes read and get to skip the treadmill. Thus for OBDII cars adjusting the turbos won't do squat.

     

    But don't know why a turbo car with low boost would be any more capable of passing emissions than a N/A car. I mean, turn off the boost and that is essentially what you are left with.

     

    Now if you were to replumb the turbo so the excess boost is pumped into the exhaust, then you would be pumping so much clean air into the exhaust that the fart sniffer will read very low levels. Your only problem then might be the visual inspection.

     

    Remember, the solution to polution is dilution.

  12. I was eyeballing an LT4-ZF6 set up on ebay a while back. I did a search (back before the software switch when half the posts got lost) and determined the ZF6 as not a good match for a Z conversion. The tranny is expensive, the clutch is something odd (and also expensive) and repair parts are even more expensive yet.

     

    There was only 1 guy who was trying to install a ZF6 and he came to a dead end with the shifter came up somewhere in the middle of the driver's seat. He showed pictures, but I never did find a post on how he resolved the issue.

     

    The best advice I got for the LT4-ZF6 package was to sell the ZF6 to some vette guy doing a restoration and buy a T56. The transmissions are worth big $$ to the guys that have to have them.

  13. Man, excellent link! Perfect for a FAQ page.

     

    That site said to not reuse the R180 halfshafts with the R200. Not the way I did it and no problems in many years of driving.

     

    Last, the 69 through early 72's had the diff mounted further forward. This requires grabing the longer driveshaft and turning the front diff mount around 180 degrees. Including this info would make this a perfect FAQ answer.

  14. Sorry...I reread my message and didnt realize I was being vague :)

     

    Will it work CLEARANCE wise on a V8 swap!

     

    While I hope someone who has similar supports will chime in, I don't see why the bars shown above won't work. A V8 doesn't come as far forward as the L6, and with this set up the bars between the strut tower and firewall are high up with a gap in the middle. It looks like this set up would work fine. In fact, I saved a copy of the pic!

     

    My concerns are

     

    1) what bracing was applied to the firewall. The sheet metal is relatively thin there. Is there a cross piece behind the firewall in the cowl area?

     

    2) Battery access

     

    3) Is there still enough room for the brake booster and clutch master cylinder?

     

    A number of the cars I have seen have braces going from the top of the strut towers backward down the the front of the rocker panels. This pipe could be completely our of the way and would, when combined with the rest of the piping, should make the engine compartent rather bullet proof. I don't think that addition would cause any header clearance issues.

  15. I think most people add roll cages for safety, not stiffness. The ITS spec cage Katman posted an article for says the rules specifically limit the number of chassis attachment points and prohibit passing the cage through the firewall. good for safety in a roll over or collision, but I wonder if the limits are to force cars to race with closer to stock stiffness.

     

    Add some sticky tires and 40 or 50 more HP and you may not notice bad things until after they have happened. Also if I remember right you are running with fairly soft springs (Nissan Euro springs?) Like someone posted here once, if you stiffen the suspension, then the rest of the car starts to act like a spring.

     

    Maybe just the combination of relatively soft springs, street tires and lack of truely competative driving means you will not notice the body flex.

     

    The paint cracks on my stock 1970 240 tell me I need to do something, V8 or not.

  16. Might do a search since the northstar has come up before. One member had one he was practically giving away. Expensive to work on. Someone else chimed in that a set of piston rings listed in the catalog at $500.

  17. My dead stock 240 use to do well when driving around the LA basin, but the first trip to Big Bear with the Santa Anna's blowing and I was forced to stop several time to cool down.

     

    The real early 240's were known to have problems with air turbulence under the car at speed. This prevented a smooth flow of air through the radiator. That is why Datsun eventually fit a chin pan that bolts between the frame rails just underneath the radiator. You can still buy these from MSA.

     

    I eventually solved any overheating by installing the chin pan and having the radiator recored to a 3 row core. I also added an oil cooler, but I think that was overkill.
