Did someone say V-3 kit, almost done

My last installment had me and my Datsun mechanic buddies trying to decide where we were going for lunch while checking out all the chic professional ladies in our downtown neighborhood. But - after lunch and a visit to the stereo store we eventually had to get back to those 73-74.5 Z car induction systems.

Between the time the Nissan engineers left our dealership and the kits became available wasn't too long but until that happened the first blush of 73 Zs had to sit on the dealer lots and at the ports. They took up space and more importantly they took up floor plan $s.  When all was said and done the the best the V-3 kit could do was make most of the affected cars drivable when the air temp was below about 80 or so and the humidity wasn't too high.

Over the following 2.5 years Nissan issued service bulletin after bulletin trying to get a grip in what was becoming a real problem. In the end they issued more service bulletins on this induction problem than any other system on any other model I was involved with in my almost 10 years of dealership employment. Sometime in 74 the  engineering dept. put all of the bulletins in one volume. I had never seen the compilation book until several years ago when I was able to snag one from e-bay.  Among the many modifications listed is the one I find to be the most radical, and the most amusing. It was authorized for use only in those parts of the country that had very hot humid climates. It was the installation of a massive hood scoop! Now, before you, a dealer, could cut up your customer's hood you had to have permission from just about everyone from Mr. K on down!  I have that book somewhere but I just can't find it. I've included a couple of pictures of the the interim attempts to organize the bulletins. I've never seen one of the hood scoop cars.

There was one factory modification I was able to use with modest success but to this day I can't understand how it was legal. You simply attached a length of vacuum lose to the end of the float bowl vent. You secured the end of the hose using rather fine stainless wire. You then ran the end of the hose to a space away from the venturi. No more partially vaporized fuel being directly ingested by the carbs. 

Next time - the final cure, my observations and opinion.

@jalexquijano there's information in here that may help your 240's vapor lock problem you've struggled with. The added length of hose is a fantastic idea I think. Whether it works is your's. Do not assume it's a fix for YOUR car. Just a hopeful solution or at least helpful to your car.

You're reading the same thing we all are so what to do with the information is totally on YOU. 

Edit. I know you have round tops and a 72 year model so please save your time telling that. Read between the lines and hopefully you'll find something useful.

Obvious -  that's it!

Yeah, if I took my car into the dealer for a problem and it came back to me with that huge thing on the hood "to fix it", I would not be very happy about it!

"Massive"... In your part of the world, that reminds me of other things like "snarlin", "bone dry", "hobblin" and the Good Ship Grease.     ROFL

That DC car could probably be flipped on BAT for a few thousand profit.  Not many pictures of underneath but the battery tray and the few that are there look pretty good.

Here's the text.  Somebody's probably going to buy it soon.

p.s. edit - forgot this part - "1971 Datsun 240z - $16,200 (Falls Church)"

"1971 Datsun 240Z
HLS30-35788
Northern Virginia
Parked in a garage since 1985. Car is carrying the original motor, unmolested, with its E31 head and four screw carbs. Engine turns over, have not tried to start it. 48k showing. Some prior body work evident, exterior paint is not original. Engine bay appears to be original paint and still has the 919 Paint code sticker (yellow). Tires are Michelin XWX I believe from 1980 if I'm reading the sidewall correctly. Series 1 center console, but Series 2 gauges, B-pillar trim, rear hatch, steering wheel, and valve cover. Interior is fairly all there. As far as the rubber floor mats, the underlay, the carpeting, and most of the interior plastics go. Dash is cracked, seats are deteriorated. Some spares included, which includes new seat covers and some front carpets. Two hubcaps. Clear Virginia Title"

That green Z would have at least had 10-15K more in bid momentum a year ago.  The S30 is still somewhat within the reach of mere mortals, but the same demographic is being impacted more by the sour economy than the Ferrari and Lamborghini crowd.  Moreover, the liquidation of the Prancing Horse Z collection on Bring a Trailer about a month ago probably scratched the immediate itch of any serious Z collectors with deep pocket for the near term.
