datzenmike Posted February 25, 2012 Report Share Posted February 25, 2012 Datsun? truck, car, Lseries, year???....no wait..... Quote Link to comment
Dat Lurka Posted February 25, 2012 Report Share Posted February 25, 2012 I'm assuming it's a 59' datsun with a Allison turbine. In which case I don't know what you should do. Quote Link to comment

elfirebeasto Posted February 26, 2012 Report Share Posted February 26, 2012 I've been watching this guy's posts. I don't recall the year, but I know its a 720 with a carburetted z24. I'm kind of curious about this one myself. I'd like to do a vac line delete, since half my lines are rotted out, broken, plugged with screws or just missing. Quote Link to comment
datzenmike Posted February 26, 2012 Report Share Posted February 26, 2012 Every year was slightly different then federal or California (he doesn't have is profile filled out, don't know where he is) You sure it's a carb and not the later Z24i with throttle body injection? Quote Link to comment
nissanprerunnerdavid Posted February 26, 2012 Author Report Share Posted February 26, 2012 Elfirebeasto nailed it. 1985 z24 carbed. Sorry i forgot to mention that. Quote Link to comment
nissanprerunnerdavid Posted February 26, 2012 Author Report Share Posted February 26, 2012 And im from washington. Quote Link to comment
datzenmike Posted February 26, 2012 Report Share Posted February 26, 2012 I wouldn't start yanking hoses off or you'll end up with the truck the doesn't start, starts but won't drive, drives but poorly with poor performance and mileage. I would try to get the hoses sorted and properly connected. Look for cracks. I don't have the '85 but these are from the '84 FSM Just in case your truck came from California.... .

elfirebeasto Posted February 26, 2012 Report Share Posted February 26, 2012 Just because you mentioned cali, is there anything one should look for to denote where the vehicle was intended to be used? Vin character perhaps? Quote Link to comment
nissanprerunnerdavid Posted February 26, 2012 Author Report Share Posted February 26, 2012 So does thats mean you shouldny do it?? Cause i have read that it cleans up you bay alot and also gives betterperformance. Is there vac lines you can take out and also can i take out my carbon cannister? Im just trying to take out and much of the emission and vac lines as possible but i dont know which ones to take out. Quote Link to comment
DanielC Posted February 26, 2012 Report Share Posted February 26, 2012 There are two emission systems you want to leave in place. The PCV system, it helps keep the crankcase cleaner, and the negative pressure in the crankcase reduces oil leaks. The evaporative emission system prevents gas vapors from escaping, and runs them through the engine instead. If your engine is tuned good, it can actually use a little less gas with these two systems intact. Quote Link to comment
datzenmike Posted February 26, 2012 Report Share Posted February 26, 2012 It will not perform better. There are no magical hidden 10-15 horse power hidden in the Z24 that can be released by removing 'some hoses'. People have very little idea how the Nissan emission systems work, and what the don't know, they fear. This leads to suspicion that they are being robbed of something like performance. For the most part the emissions equipment in benign in operation. Take the carbon canister. It collects gas fumes from the carb and the gas tank when the motor is shut off. When the motor is running a valve opens and the stored fumes are run into the carb. Has zero effect on running/performance but if removed the fumes have no where to go and stink up the cab, so again why bother? In the long run it's easier to fix a few cracked and missing hoses and maintain the emissions systems than to remove stuff and end up with almost impossible to diagnose problems.

OP should check out NICO for a good pictoral of the vac line system. Quote Link to comment

GreenD21 Posted February 27, 2012 Report Share Posted February 27, 2012 Here's a very helpful thread on vac lines for the Z24. http://forums.nicoclub.com/vacuum-line-placement-1986-z24-gas-motor-t530372.html The VIN will not denote the vehicle's intended market, only it's origin.

datzenmike Posted February 27, 2012 Report Share Posted February 27, 2012 Good stuff! With this info the emissions hoses should be checked and repaired as needed. Hoses are the weak point as some pull off when removing the air filter, owners put them on wrong or just plug them. They crack from age and use too. Quote Link to comment
GreenD21 Posted February 27, 2012 Report Share Posted February 27, 2012 When I replaced all 30+ft of hoses on my D21 I noticed an instant increase in performance...or regain of lost performance. It was the most effective $15+/- I spent on my truck. Quote Link to comment
nissanprerunnerdavid Posted February 27, 2012 Author Report Share Posted February 27, 2012 Ok awesome!! Thats just what i was wondering. Thanks all once again. Quote Link to comment
elfirebeasto Posted February 28, 2012 Report Share Posted February 28, 2012 You could convert to custom hard tube if you wanted to clean it up a bit in the engine bay. Less random floppy hoses, more metal. Brake line or copper tubing or something would probably work. Just a random idea. Quote Link to comment

nissanprerunnerdavid Posted February 28, 2012 Author Report Share Posted February 28, 2012 That probably would rack up the $ though right?? If i have extra cash flow i will definatley look into doing that! Quote Link to comment
