I will probably be using 2 relays. The advantage of the Bosch style relays is that that they are still available and easy to find in case they need to be replaced. I will also keep some of the original relays, but I want to keep the amount of them to a minimum.

2 separate relays is my Plan B, but I would like to use as few relays as possible because I will also add new relays for the headlights and an electric fan .... and I fear I might be running out of space. But if there is no other way I will go down that route. Thank you for the link, that helps a lot.

That's good to know, but I am thinking about replacing them with modern equivalents, so that I can use them with a modern relay holder/ fuse box.

My car was built 08/1977 - I think I have a different relay layout. Or we are talking about different relays.

Male contacts on the ECU are 3.0mm.

I agree, it is not much difference, but there is a difference compared to the drawing. And all contacts are 3.00 +/- 0.03mm.

Maybe the JPT are the correct ones or at least compatible, I just ordered them to test if they might work. But on the drawing I found a width of 2.80mm and I measure 3.00mm. Because I don't have the correct extraction tool right now I could not compare other dimensions yet.

Are there any part numbers for the old male and female Yazaki contact pins? Beside a suitable extraction tool I am also looking for new pins that I can use with the old connector housing. One of the previous owners bypassed a wire and I would like to integrate it into the connector again.

Hello, does anybody know what contacts are the correct ones for the 280Z 35Pin ECU connector? It is an AMP connector, but I cannot find the correct contacts. At first I thought it were the Junior Power Timer contacts, but they don't have the exact same dimension - they seem to be a little too small...according to the drawing that I found. I would like to completely rewire the injectors. Thank you for your help.

Hello, I own a 280Z and in the book "How to Modify Your Nissan & Datsun OHC Engine" by Frank Honsowetz he describes enlarging the oil-jet from 2.0 mm to 3.17 mm to increase oil flow to the head to improve oil lubrication of the Cam and rocker arms. I found out that the L28ET uses a different oil pump and different oil jets. Unfortunaly, I cannot find the bore size of these jets anywhere and I am really curious if the Nissan engineers increased the oil flow to the cylinder head for the Turbo version. Does anybody have the opportunity to measure the openings of the oil jets for me? Thank you very much.

Does anybody have a good replacement heater core that fits into a 280z? The recommended part from the Ford Escort is a little too wide.

Hi, I am planning to upgrade all fuses and most relays in my 1977 280Z. Are the any good modern standard replacements for the Fuel Pump Control Relay and the Electronic Fuel Injection Relay? Or is the only way to achieve the same function by using multiple standard relays? Thank you for your help.

There were the wrong nuts in the package.

Just FYI. I had two wrong gland nuts in the package. M52 was required, but they were only M51. Without the damper centering the gland nut, it was a very loose fit and the nut popped out at around 50Nm. The outer diameter of the gland nuts should be around 51.80mm to work correctly.

I know that you want to help me and I appreciate it, but I still would like my original questions answered. I was offered a refund, if I sent back the dash, but I need a good dash. Is this a new problem with a new batch? Or is this normal and most people accept this?
