Lewis Maudlin Posted March 17, 2005 Share Posted March 17, 2005 I am new to the world of fuel injection. My last Z was a 355sbc. I now have a 1978 280Z which is pretty much stock. I took the airbox off, but that is about it. I have replaced the plugs, wires, cap and rotor and still have an annoying sputter. I have decided to replace the fuel injectors. The hoses connected to the fuel injectors are rotten and need replaced too. Is there anything else I should do while replacing the injectors? Should I get the same injectors? If I get bigger injectors will it change my performance without changing other things? Will bigger injectors change my gas mileage a lot, I drive 70 miles a day? Need help. I am willing to spend a little money, but don't want to spend too much money since I will go turbo in a year or so. Thanks. Lewis. Quote Link to comment Share on other sites More sharing options...
Lewis Maudlin Posted March 17, 2005 Author Share Posted March 17, 2005 I found some Beck Arnley remanufactured fuel injectors 6 for $111.00. What do you think? Sounds like a good way to go? Any advice? Quote Link to comment Share on other sites More sharing options...
2126 Posted March 17, 2005 Share Posted March 17, 2005 Without coming off too sarcasticly....if you can't answer your own questions about your current injectors, how in the world will you deal with installing a turbo setup? You may want to consider taking your Z to a quailfied mechanic for a complete tuneup. Your a lawyer...you can afford it! Or, as one does when preparing a legal matter.....research, research, and more research. Quote Link to comment Share on other sites More sharing options...
Lewis Maudlin Posted March 18, 2005 Author Share Posted March 18, 2005 yes that was pretty sarcastic. I don't think that type of behavior is or has ever been tolerated here. If you want to go explain how much smarter you are than the next guy, please go to the Nascar forum or the Corvette forum. This forum has always been about Z cars and helping people with Z cars.

z-ya Posted March 18, 2005 Share Posted March 18, 2005 Don't waste yourmoney on reman injectors, send them out for cleaning and testing. http://www.witchhunter.com will do the whole set for around $100. Also, the intake hoses are very important, especially the one between the TB and the AFM. If it has cracks, the engine will idle rough, but run OK off idle.

innerware Posted March 21, 2005 Share Posted March 21, 2005 There is a possibility that the injectors are fine and the wires (connectors) to the injectors are old and not sending the proper signal. It was pretty inexpensive to replace those connectors and fairly easy too. If the rubber boots are all cracked then I bet you have corrosion at the contacts. Good luck.

Sorry if my post offended you. Just figured if you were perplexed with your situation, you might be better off visiting a mechanic. And regarding your comment about someone being smarter than the next guy.....funny, but I never said anyone was smart, dumb, or otherwise. Don't be so touchy...you'll live longer!

Sometimes anybody can benefit from a tiny lecture..that's what this forum is all about -listen, hear and learn. Quote Link to comment Share on other sites More sharing options...
