[im getting a 82 280zxt, parts car, what do i need to do to s]

wow, Eurozx disappeared a LONG time ago. I remember his black car.

 

I'm honored to post in this 8 year old thread

[Overall Rating for 280zxt with 300zxt ECU Swap!]

Fenders are $25 each in the wrecking yard here. I dont' have any but if I did, you could drive here, swap them on, and drive back. Duty free

(oh ya, you're not in BC)

[WTB: 280ZX rear bumper - MSA fiberglass type]

Like this...

 

 

I know I can get these new. I'm just wondering if there is a used one around that someone wants to sell.

[Question Regarding Injector Wiring.]

i obviously have to run some type of fuel control, would a 280zxt computer do it?

No, the 280ZXT ECU does not take any modifications into account on the a/f ratios. The oxygen sensor makes very little adjustment for richness

would i need that, plus a piggy back system?

I don't believe there is a piggyback system. If you do a 1988-89 Z31 (300zx) turbo ECU then you have the option of having it reprogramed for those injectors. Then you would have to have it programmed again when you go with forced induction.

would the injectors be over baring for a n/a L?

I believe so. I think the factory NA injectors were 240cc (?) 440cc is very large

 

All the work you mentioned could be done, minus the injectors and it should run fine until you're ready for a standalone ECU or Megasquirt to go along with the 400c injectors.

[Question Regarding Injector Wiring.]

Sounds like you got it running in your other thread.

 

280ZX and 1987 300ZX are single batch fire. No need to number injectors.

 

1988-89 I hear are two banks of 3 so it does matter a little for those ECUs.

[After 300zxt ECU swap how do you set the timing]

oh ya Tim Hortons is good stuff. I've only seen them in Canada though.

 

my impression of the low compression L28 turbo is laggy lag lag... That Z31 ECU sounds like a miracle! Only thing better would be slightly higher compression to add more torque and throttle response.

[Overall Rating for 280zxt with 300zxt ECU Swap!]

Sweeeet!

Now I want to do my swap.

[After 300zxt ECU swap how do you set the timing]

I did not know about the TPS trick. I think I just read how to set timing in the factory Nissan service manual and did it that way by turning the distributor.

[After 300zxt ECU swap how do you set the timing]

With a timing light sure, advance to 24 deg and see how it runs for a while.

 

Others mentioned they went more advanced. I never have. My old turbo I ran at 24 on premium. I was constantly having boost leaks even though the engine was stock. I wanted the extra protection...

 

my recent car is a factory turbo. no leaks, all stock right now. I run mid grade but plan to do Z31 ECU (1988) and some other junk. Not sure what I'll do on timing. time will tell

 

I highly recommend you get an Autometer manual boost gauge. They are much more accurate than the factory gauge.

[Maybe someone will answer my cries for help lol]

could be a very small boost leak

 

I had a small leak at one of the injector o-ring seals when I did a turbo L28 engine swap

[Maybe someone will answer my cries for help lol]

you're probably not getting the "wide open throttle" position sending a signal to the ECU. So the fuel supply is limited, reaches a lean point and makes that popping backfire sound.

 

Who knows what the Z32 TPS has compared to the Z31 or S130. Why use it?

 

Isn't the swap supposed to use the 280ZX TPS and just wire it in?

[After 300zxt ECU swap how do you set the timing]

The 300ZX turbo has slightly higher compression than the 280ZX turbo so I would guess that is one reason the 300 timing is farther back.

Also the 280ZX ECU is not very precise on the fuel map and runs a bit rich under any sort of boost or anything above 3000 rpm. The richness and low compression fights pre-detonation. (also meant to run low octane fuel) 300zx runs more lean but it is a more proper mixture for more torque and horsepower.

 

If you're running high octane fuel only then it would make sense that you can run the advanced ignition timing. Listen for pinging though. Also, are you at stock boost right now? I would assume so since you made no mention of other modifications.

 

I did read that 1988-89 300ZX had a smaller turbo, lower boost, but higher static compression. The ECU supposively pushes timing another 2 deg advanced under boost. You won't have to worry about this if your ECU is truely a 1987 though. 8-bit

Get the hood too. Turbo scoop.

 

scoop or die!

A guy there was giving away a free hatch with no glass but only if you picked it up in person in Washington state.

[2009 Armada diff LIMITED SLIP]

Are you also swapping to a solid axle or did they switch to IRS in 2009?

[Is it possible to make my 280zx an AWD car?]

I've emailed that guy with the 280ZX 4x4 a few years ago. I think it was a Nissan 720 4x4 with a Z22 engine. Those are 6-lug hubs, same as all Nissan trucks.

 

A truck has a IFS setup with a small R180 diff hanging under the engine. Not what you want for a low ground clearance car.

 

If you can find an AWD steering rack like out of a Skyline that would be a good start.

Then there's always the SR20DET like you said... Pulsar running gear. Nissan did make a awd Stanza but the drivetrain may not hold up to 200 foot pounds of torque.

[L6 maxima]

There was a narrow window of production years for the maxima (82-83ish? maybe 84?) that had a bolt-on bracket for the rear disc brake caliper.

I believe that was the first year of that particular body style. 1981 only. 1982+ they switched to a welded bracket but I'm not sure the wagon was the same. The Maxima wagon might actually have rear drums since it has a solid axel.

 

That generation of Maxima was 1981-84.

 

also, the front struts and brakes look like the 280ZX style but they are not 100% the same. Brake pads ect do not switch out between them and a Z. Good only for core charges.

Isn't his mom worth more than that?

You could get a fake money order for $500,000 if you wanted to.

[Need L28et Dimension]

Find a Z31 turbo with a blown engine and put the L28 in there!

[my back brakes are different year??]

wow, new calipers and stainless braided brake lines.

 

I'm not sure how to visually tell differences in the control arms from 79-81 and 82-83.

[Trans Swap]

It is not that hard of a swap. If your automatic Z is in good condition then swap to 5-speed. If your Z is messed up, then possibly get rid of it and find a better one with a 5-speed.

[my back brakes are different year??]

maybe a prior owner needed new rear brake calipers and bought used ones from a 1981 because it was cheaper than $250 each from Nissan.

 

If they don't bolt on someone may have just swapped the entire rear trailing a-arm

[cant get L28et rear main seal on]

seriously you guys

Just put the 3-speed auto back on

It would have been easier

Can you post info on the brand name and part numbers? Maybe scans of the box you got.
