My ZCARCD no longer works in any of my computers. I assume its not compatible with the new acrobat program. Has anyone else had this problem?

The heading on this thread reminds me of the old line....... "when you turn your car on, does it return the favor?"

The car has a stock exhaust manifold and the MSA exhaust system. I'm going to check the torque on the exhaust manifold today.....

Im pretty certain its not detonation now. I retarded the total timing to 18 degrees, zero initial and the noise is still there but the power is way down. Still looking for input on best total advance for this engine....... I think the noise may be from an exhaust leak..... although none is evident at idle.

I have had an issue with my 240z for as long as I can remember. It sounds like it is experiencing detonation at part throttle under a load. The engine is stock with the exception of a 280zx EI distributor. The initial timing is set at 7 degrees at 750 rpm. The total mechanical advance is all in at 2700 rpm. The total timing (initial 7) plus (mechanical 18) totals 25 degrees. This seems pretty tame to me. A typical performance v8 usually produces best power at 30-35 degees of total timing. I'm not certain how much a datsun inline 6 needs. I have tried takeing the timing back and enriching the carbs but nothing seems to effect the sound/feel that I percieve as detonation. I have triedit withand without the vacum advance connected. Currently driving without any vacum advance but the vac advance when conected adds 24 degrees. Suggestions?

How about a braided brake booster hose?

431 rwhp in a 2200lb car equals a 10 flat in the 1/4 mile, if the tires could hold the power.

That should do the job....................

Jared, thumbs up for a very well thought out build and balanced car overall. The attention to detail is amazing and inspiring.

This is a really cool story, and the car is obviously significant. I just can't believe the amount of hair splitting that has occured on this thread, people who treasure the low vin cars should be happy that this car has surfaced.

I had a truck wrapped a couple years ago. Great for advertising......but no sustitute for paint.

We drive a 350z and a 240z, many 350z drivers are ignorant of the heritage. However when we have the 240z its is amazing how many people , young and old, comment on the car. It seemes that all of the older people have a story to tell about a Z. The younger kids just think its a really cool car.

I have used silver metalic spray paint on engines that had repeated headgasket failures and it does work. I'm fairly sure coppercoat would have the same effect.

Ok, that must be the problem. I'll have to check those connections.

I installed a 280zx alternator from a 83 2+2 in my 71 240z last summer. I used the conversion plug in place of the stock regulator. I recently noticed that upon startup the charge indicator shows a discharge until the engine is reved to at least 3500 rpm. Once that rpm is reached its like you flipped a switch and the alternator begins charging and actually charges very well,even at a low idle. However after I turn the car off and restart it once again shows a discharge until it is reved again. I have searched the internet and found this described on other alternator upgrades (GM 1-wire) but the "cut in" occurs at a much lower rpm. has anyone else experienced this on an alternator upgrade?

Wow, the engine has a crank and a cam. Amazing

Wow! check out that interior! http://portland.craigslist.org/mlt/for/1208419184.html

Sunday morning? Toni and I should be able to make that. I doubt we will bring the 350z this year. It's headed to the bodyshop thanks to a hit and run driver.........

I have a similar set up.How high are you reving the engine to check total timing? The zero mark is the bottom mark (of the 5) on the crank pulley. I had to rev mine to 4k to be certain all of the advance was in. My problem was to much advance. Also I believe that the number stamped on the advance tab is distributor advance, which is half of crankshaft measured advance. So 8.5 would actually be 17 measured at the crank. Confirmation???

Thanks Bruce, If I send you a distributor can you recurve and rebuild it? Also are the vacum advances available for replacement?

So what would the overly rich idle mixture indicate? Worn needles? Float level too high?

So 35 total advance in a stock l24 on premium pump gas is about the max? Any thoughts on the air fuel ratio variation from idle to WOT?

Thanks Bruce, when I return home I'll check that number. Are differnt T-bars available and from where? Also is it likely that the large disparity in mixture between idle and WOT is caused by worn needles or is that normal?

That is total advance, vacum plus centrifugal. I should have checked with the vacum advance disconnected. The vacum advance is ported vacume so there isnt any vacum siginal at idle. Only when you crack the throttle open. I am considering changing to manifold vacum.
