shuttlefever Posted February 13, 2012 Share Posted February 13, 2012 Hey all, I have a 79 zx non turbo. I am getting ready to do a mega squirt change up on it. I have searched the forums for some suggestions for what i can leave on my engine and what i can get rid of. Not having too much luck, not sure what wording to use for search parameters. Mostly i am looking for a wiring/vacuum schematic for the emissions and fuel injection system to help identify the sensors and assorted valves that i can remove from my engine an not make too many issues for myself. I want a clean engine compartment. I would like to remove the clutter. And in the spirit of crap on my engine i am not familiar with... What is the valve on the throttle body underneath?? appears to have a vacuum line on it?? Any direction for resources on here or any other sights would be greatly appreciated. Thanks in advance!

BluDestiny Posted February 13, 2012 Share Posted February 13, 2012 sounds like you need the FSM http://xenons130.com/ Also you should check peoples build threads out to get an idea of what it should look like. Quote Link to comment Share on other sites More sharing options...
shuttlefever Posted February 13, 2012 Author Share Posted February 13, 2012 thanks i will check into that later today. mobile devices are not great for research!! D~ Quote Link to comment Share on other sites More sharing options...
shuttlefever Posted February 14, 2012 Author Share Posted February 14, 2012 been searching on here and xenon for so long my eyeballs are getting googley!!! I guess i need to figure out how to narrow down my search parameters. All i can find when i do a search is manifolds for turbo cars, I am not sure if there is a difference between the turbo intake and the N/A one. Any advice??

FricFrac Posted February 14, 2012 Share Posted February 14, 2012 You just need to download the FSM - those are the manuals for your car and they are already divided into sections. You'll have different vacuum lines for different systems so for the Emissions stuff you'll go to the EC section, etc, etc. You can use the air temp sensor in the AFM but I would get rid of that resistance - toss the AFM and put a piece of aluminum 3" piping in it's place then add an IAT before the air goes into the runners on the plenum or before the throttle body. Use the CHTS as it's more accurate than the sensors on the thermostat housing. I'm not using any of the idle adjustment valves on the top of the plenum - there is a lot of piping up there you can get rid of. You might want to use an idle control valve of some sort so you could use the ports on the stock manifold if you decide to go that route.

Can I hook up the fuel lines a different way with the regulator at the end of the line, then return?? that would eliminate some of the clutter in the fuel area. If there is no major issues with any of the goofy valves,(other than the IAC) I will just do some pluggin and yankin. I can fab any odd plates and covers i may need. And the IAC can be re located to underneath or off to the side somewhere i think. I will dig in a bit more once i go lay my eyes on a FSM. Thanks for the help!
