I am new to this forum and am looking for some assistance from people who know what they are talking about. I have a 78 280z and I can't get it to pass smog. It always comes accross too rich i.e. too many CO's. I changed the water temperature sensor after running the tests in my Factory Service Manual and tried again and no good. so I ran some more tests and changed the throttle position sensor and the Mass Air Flow meter and now the car will not run for a long enough period of time for me to get it to the smog shop. I set the timing to 10 btdc and I also did all the tests I could find on my Mass Air Flow meter and everything looks good. The funny thing is when I ha…

Just have a question. I was going to buy an aftermarket fuel pressure regulator and gauge, but I was wondering what the fuel pressure should be at on a stock regulator. Thanks

Has anyone actually done the switch from triple DCOE type carbs to TWM throttle bodies? I am considering this mod and wanted to see if anyone has any dyno results to prove the TWM setup is better on a NA L6.

So I'm running with a suggestion that my '75 280Z is having engine problems because trash in the fuel tank is clogging the screen. A member of our local Z Club offered this up from his own experience. The symptoms I described were indentical to what was going on with is car - running well for some period of time and then suddenly loss of power, sputtering and finally stops running. Let the car sit a while and start it back up and all is well... sometimes. Over the weekend I drained the tank and yes there was some particles in the fuel which I strained into a gas can. Didn't really look like rust. So I dropped the tank and got a little surprise. On top of the tank there ap…

I need some help!!!! the fuel pump of my 280ZX was loosing pressure so i took it off, and replaced it with an homologated one, because i couldn't fine the original. The one that i found is the pump that works in the german cars like old BMWs and Mercedes, and it has a pressure of 95 psi, what i want to know is, is that pressure the right one for my injection system or maybe is it too much or too less??? can somebody help me??? does anybody know what is the right pressure??? the car is running fine but sometimes it smells like gas!!!

I recently just replace my Cali 280z's exhuast(stupid catylitic converter) with a 240z exhaust and might i ad it fit perfectly however I put on the whole entire fuel injection system, but the heat shield doesnt fit in because the exhaust manifold is slightly different. It fits perfectly without the heat shield. Since i no longer have a cat could i just get rid of the shield or should i fabricate it to fit properly. Also i cant get the damn thing running again. It smells like there might be water in the gas so i added some of the HEET water removal stuff but still nuthin. It ran alright on this gas before, but ill drain it and try again, if this doesnt work what should…

i have 75 280Z that i plan on keeping the stock motor in. I plan to use the MSA stroker kit and run some boost on it also, and wanted to know what others have used fuel management on the non carburated motors. I believe the 75 is fuel injected (correct if i am wrong), but not electronically controlled. I am more used to fuel systems on newer cars and this is the first time I have modified a car made before 1994. any help is appreciated.
