Thanks yall, my book said the same thing it just said that i would reach infinity instead of continuity. So i was kinda confused.

My 2 Cents Deffinately sounds to me like your piping isn't ran right all the way and u deffinately still have a vacuum leak I do remember another thread that was discussed stating if your not going to hook up both pcv hoses to the intake, the one ontop the valve cover and from the block you should put a filter on them because it will cause a another vac leak. As for the idle screw, I don't beleive it will work properly with out the iac tubing (mess) is hooked up.

No problem

Well that sounds about right because those are the contact points your use to see when your at idle but the center is for coast. But try switching them before getting bigger injectors.

Deffinately sounds plossible since your jamming alot of air into the cylinders with wider valve openings and your fuel is just barely igniting. Anytime you up your cam and intake your always up your fuel injectors and might have to upgrade the computer but as long as the cam isn't too high your should be fine with bigger injectors.

well my z idles fine with out the tps sensor connected so maybe the cam is too big for your fuel injectors cause obviously your air is getting to your cylinders

Well your tps might be fine, what about the connector to it? I had problems with my tps sensor connector. And is the wiring harness stock what upgrades does it have or is it stock? Also you might want to look into your fuel pressure, at idle and when you step on it.

I replaced my tps sensor and im having issues adjusting it with an ohmeter and I went searching threads but no one really touched base on adjusting tps with and ohmeter. Could somone give me some tips on what signals the tps sends out on what prongs for idle cruise and wot?

Sounds like you could have an exhaust leak or a fuel air ratio problem, maybe even a pressure leak. Also be sure to check your tps position if you replaced or took off and put back on

Thanks your information has been more than helpfull and im still getting used to how this site is set up.

Yes I do have a back up car to drive i figure this car will be down for a while if not a year so I can work the bugs out of it and stuff. So i do deff have time thats not an issue. Also do you know where i can find a custom intake. I heard there were manufacturers that make them would you know where to start?

almost 2 years as a daily driver

I was told to post a budget and goals but i don't have a budget i just buy part by part. But my goals are i want this motor to deff rev higher and produce a great amount of power but i want to be able to drive it out side of the strip. Emissions is not an issue for me.

Im kind of confused tho i have no idea which one to go with out of the megasquirt and is it good to go complete kit or build it your self. This is my first time dealing with a put together efi system. So I have no idea where to start

Awsome now if I get the megasquirt which i saw in a similar forum and went with the head and cam and intake right and took out the afm if I had any tech question could you help me? And what components does the megasquirt not come with?

You guys are awsome. This is more information that i ever thought i would get. My budget isn't set. I can save for each part, im not looking at getting this done in a week. But how ever i would like to drive it normally but i do want power. Im still trying to jam all this in my head with learning the physics and stuff. Do you kno where i could start on that efi system and how would that tie in to my normal ecu and interior wiring. And how would i find the ratio for the intake cam and head porting?

I thought the valves and ports on the turbo head were bigger than that of the N/A head and what does the P70 offer that makes it a better match than the p90?? And your saying i could take a p90 and swap cams?

Kool so the throttle body is not the place to start. What I want to do is change the head i have to a turbo head but keep it N/A i was hoping on getting a custom intake and bigger throttle body and bigger cam. I was told with the turbo head i could encrease the rpm range so i wanted to open the intake as much as possible since im not using a turbo ( this includes headers). So if i do that i kno i need to upgrade my fuel system so keep up with the air coming in. What can i do about that? Just read the discussion in that link and the discussion opened my mind to keep the throttle body stock but try to get the heads intake ports opened along with the runners of the intake. Will keep reasearching opening head and intake. But that deffinately makes since not to open the throttle body but to open the intake and head first before even thinking of the throttle body. I want a good throttle range not full power at 50% throttle

So your saying the turbo swap would be a better bet?

So the throttle bodys are the same then, i can just upgrade the throttle body to the big throat throttle body i think made by msa if i were doing a throttle body swap? and if i start at the ignition what could i do?

Is the throttle body off of a 82 or 83 turbo and upgrade for the 82 N/A?

Well thank you very much you've been a big help. Also when i do a cam upgrad don't i have to upgrade the valve train aswell? And the timing gears on the cams are the same from the N/A cam to the turbo cam?

I figure enlarging the first obstacle will allow more air to be pulled to the throttle body so if i get a big bored throttle body it wont be in vaine. And thank you for that info on the cam now the stock cam of the p90 wont be good for higher rpms right? Also do you think the header for the n42 will work with my s130 style steering?

My uncle said that i should be able to swap a turbo head on to my 82' N/A L28 what should i look for and on the P90 which head is better to use the hydraulic lifter head or the other? Also curious on how to swap the electronics of the non trubo afm to the turboed afm housing? (supposed to be bigger?)

im having a problem with my car it runs rich constantly but i only have a book on testing 83 280zx MAF can somone tell me on an 82 MAF whats the specs for testing the MAF
