WTB 2x 86.5-90 D21 Z24i distributors 8 plug dizzy hardbody pickup

[dimedriver]

Im looking for distributors from the hardbody pickup with the Z24i. Im pretty sure they were in the trucks from 86.5 to 90 or 91. The trucks used a throttle body style fuel injection system. The throttle body looks like a carb with a huge injector in the middle of it. I think most had 8 plug heads and I have herd rumors that some had 4 but i really doubt it. If you pull the cap and router off these distributors there is a gold colored plate under which there is a optical sensor and a chopper wheel.

 

I am willing to pay for shipping if you are not local or don't feel like meeting me somewhere, but would prefer to pay cash in person.

The D-21 with the Z24i was available from 86.5 till '90. Look for two wing nuts holding the air filter on over the TBI (which has two injectors) but with a single cover over them. All Z24i had 8 plugs, only the '80 200sx with the Z20E had the 4 plug head. The distributor is really a CAS (crank angle sensor)

 

With this CAS you can convert a KA EFI system over to work on any Z24 motor.

Thanks Mike,

I had herd stories of the 4 plug Z head but was unsure what it came on. I was also unsure of the cut off date from the Z series to KA engines in the hardbody truck.

 

Im going to try and use this in L series engines. I think if i use the splined oil pump drive spindle from the 82-83 280zx turbo it should just bolt up. I have a 82-83 280zx turbo dizzy and it is very similar to the 86.5-90 Z24i dizzy. The caps may be interchangeable.

 

I have nearly all the electronics/wiring to do this.

 

I have already started on making my own intake.

 

Now the only big item left is the Dizzy.

 

I will do a full write up when I finish with good pictures and I hope dyno graph and wide band O2 tuning.

 

I have also run a L28 just ignition off of an Infinity M30 ECU using the same techniques. That was just a trial of the setup though. I will post a video on youtube after work today. I hope to fully implement it on a L18 or L20 before I do it again on the L28.

 

I hope someone has one to sell me I really have been dragging my heals on this project because I have so much trouble finding this part.

Maybe the 280zx dizzy with the 4 cyl internals from a KA CAS??

All you need is the wheel with the degrees marks and the 4 marks at the 90 degree points for a 4 cylinder.

Im not super sure the cap will fit. I have some KA dizzys laying around I can check the disk size with.

 

I will take the 280zx turbo distributor with me to autozone and get the cheap cap/rotor there and check the fit.

The KA's came with different base timing on the cas disks So I may need to try a few of them. I will still need these because the turbo dizzy I have is for a friends 240 turbo project. But it would widen my parts search.

The disk fit but the cap does not. :( The 280zx dizzy's screw holes are further out from the center. The cap also did not sit down right on the distributor.

 

Looks like I will have to keep looking.
