1977 280z fuel injector upgrade

(0 reviews)

I just inherited a 77 280Z non turbo 2X2. The car currently runs but needs some work done. After driving it around over the weekend, I noticed that the fuel injectors are old and leaking a little fuel, which at that point I parked it in the garage. I am planning on replacing the fuel pump and fuel injectors, but would rather upgrade these with some higher performance parts to get more power. Does anyone have any recommendations on what kind of injectors and fuel pump to buy to get more power than the stock? I dont want to pay a fortune but I also dont want cheap parts in my car.

Are you in California? I know the best Z mechanic, he's in Ventura, works exclusively on Datsuns and has a huge crowd of Z cars outside his shop at all times. He's been fixing my Z for over 20 years.

That's exactly what the problem was on my car. I had a puzzling oil leak, seep, about a tablespoon every 30 miles or so. Small spot under my car after sitting. I knew the leak originated near the fuel pump, but was fearing the worst, head gasket. This was one of the last of 25 pages of doing a search for "oil leak" that I read. Decided to go check those bolts, YES! I had loosened the bolt to adjust the alternator but forgot to tighten it. The others in the sane vicinity were a bit loose also. Took it for a drive, no more leak.

Cowl leaf screen

Guest Mike Piazza · April 25, 20251 yr

I didn't want to deal with silicon goop of any kind but my plan is to cut screen pieces slightly larger than the holes they are supposed to cover on the inside of the cowl and epoxy those small super strong magnets to strategic areas of the screen where they would fit flat against the underside of the cowl. More than strong enough to hold the screens in place and easily removable to get rid of stubborn leaf debris that might get stuck between the screen edges and the underside of the cowl.

@EuroDat I know you made this blog awhile ago. But I am going through them and find this to be an interesting addition. Do you happen to have any photos you can add to this entry so we can keep it going?
