I'm finally getting a chance to embark on this swap this weekend. But before I do, I have a question for those you have already completed it in past. Over the years, whenever my 280zxt is not running correctly, the problem is very quickly corrected by reseating the ECU plugs. I've been tempted to replace my 280zxt ECU connectors with 300zx ECU connectors because they supposedly grip better, but I was hesitant to start hacking up my wiring harness. While reading this and other posts regarding the ECU swap and the need to "cut open a donor connector" to get a few additional pins to complete the swap, I was wondering if the pins can be removed from the existing harness connector and transferred (inserted) into the new 300zx connector in the proper locations. This would accomplish two things, 1) not require cutting existing ECU wires because the pins from the harness can just be inserted into the correct position on the 300zx connector and 2)replacing the 280zxt connector with a better fitting 300zx connector.
So my question is, does anyone know if the pins can be removed from a 300zx ECU connector without destroying the connector?

I was lucky to get in on the group build for Jeffp's 3" SS mandrel bent system a few years back. Loving it!!

I think he's looking for a Borg Warner T5 transmission, not a T5 turbo....

My favorite is when you find a bolt in your driveway and you know exactly where is goes on your Z....

Double post, sorry....

FYI, the bushing on the end of the crank in a auto tranny Z needs to be removed when swapping in a manual tranny. Also, don't forget to permanently connect the Park/Neutral switch wiring or your Z won't start. You may consider swapping in an ECU from an 82 or 83 manual 280zxt. The auto ECU will work work with the manual tranny, but there is at least one difference that I noticed. The auto ECU drops RPM's faster then the manual ECU. The manual ECU holds the revs up a bit longer to facilitate shifting. If you do swap in a manual ECU, make sure its from an 82 or 83 280zxt. The 81 280zxt's were all auto and do not have the injector dropping resistors in the ECU like the later years.

Not from the '70s, but 1981 is pretty close.

I have a NOS EGR tube still sitting in the Nissan parts bag if you're interested. Its never been installed

I was involved in setting up the klearz lens build several years ago. Sorry to hear that they are no longer available. I bought the smoked lens all around. I'll post pictures tonight. I never mounted the taillight lens though, it came cracked.
Actually, you can see them in the second picture in the attached slide show. My 280zxt is pictured on the left.

Don't you love rentals... I'm sure every one of them has stories to tell.

My first Z was an 80 280zx and was my daily driver for three Connecticut winters. It was fun to drive in the snow, as all rear wheel cars are. Having grown up in Northern Maine, I was used to winter driving. The only issue was the depth of the snow. A Z sits pretty low and has a built in snow plow mounted under the bumper! My previous car was a 77 350 4-speed Camaro with limited slip diff. We didn't think anything of driving these cars through the salt laden winter back then. These were the current generation of cars being sold and all were rear wheel drive. Of course, the front edge of the hood was already rusting when I sold it in 1984....

Please let us know if this solves your problem and how much of a pain replacing the plugs was. I considered doing the same, but the thought of splicing all those wires has kept it on my to-do list.

I first installed an OEM 240mm turbo clutch when I completed my 81 280zxt auto to manual swap. The OEM clutch lasted a year or so until I turned the boost up to 8 psi and was destroyed instantly. Put in an ACT Street Performance clutch and have not looked back. Currently running 12 psi.

Phil,
I grew up in Maine also and always look forward to the annual trek "home" to see family and to enjoy the red hot dogs. All four of my sons love them. Last summer we brought a case home, some of which are still in the freezer, waiting for the grill season to return. We live in Connecticut and have never seen them available here.

72 Chevy Vega GT, 4 speed with air shocks!! LOL

My turbo is starting to howl so I'm starting the "rebuild" research. How did you make out on your rebuild. Any lessons learned you'd like to share?
-
Mike, your upgrade looks great!! Looks like you;ll be firing it up real soon. I was wondering where you picked up your battery cable terminals. I've been looking for something like that for a while now.
-
You'll have to remove or modify the popoff valve which I believe opens around 9 lbs on a stock 280zxt. Search for the popoff valve modification, it involves adding fender washers to make the internal spring stiffer. If you go the removal route (not recommended) you'll need a 1" pipe plug to close off the openning.

As a member of the Connecticut Z Car Club (CTZCC), I had always hoped Paul would accompany Bob Sharp to one of our club events. Unfortunately that dream has been banished this morning. Several weeks ago Lime Rock Park closed down for a period of time and allowed Paul to take a few parade lap laps around the track for the last time. You know where his heart was. A real gentleman, he will be missed.

Brad's explanation of the injector resistors, the 81 CAS will plug right into 82/83 distributor CAS harness plug. No difference in output.
-
Again, thanks for the update gentlemen. I'll have to keep an eye out for my clutch, which only sees a few thousand miles a year. Bo, did Act mention anything about being able to trace back manufacturing dates and identifying potential candidate clutches for failure??
-
Hmmm, I'm going to have to pay attention to the behavior of my ACT clutch Bo, thanks for the heads up. I think we bought them about the same time.

Any of the turbo 5 speed ECU's will work in your 81. The main difference between the manual and 5 speed that I noticed was the rate the RPM's fall off between shifts. The 5 speed ECU will let the RPM's fall off slower, making for smoother shifts while tooling around town.

I'm swapping an 84 ECU into my 81 280zxt. I would love to be able to swap in the 300zx connector while doing the ECU swap by transferring the pins from the 280zxt harness connector to the new 300zx connector, rearranging the pins that need to be moved for the ECU swap. This way, I don't have to splice as many wires, just move the pins around. Cant' wait to look into this tonight when I get home!
BTW, I found a blog which partially confirms the ability to transfer the pins. Looks like the 280zxt connector will be damaged in the process of removing them, but the 300zx connector has a couple of tabs that will allow the connector pins to be removed or inserted.

Good luck and let me know what you find.
