I just picked up 1975 280z.

Body condition was amazingly good and minimum rust. Only small dent on the passenger's side of the door and fender.

 

The goal for this project is phased project.

1. To run the engine

2. Fix minor rust

3. 240z bumper and tail light conversion

4. Fuel injection to Triple weber swap.

5. Paint the car

 

Let's see how much progress I can make monthly...

Weather is getting better and my health condition is also getting better.   I decided re-do rear window installation.   This time, I install trim onto the rubber before install

Check out my solution to this, starting with picture 37...   http://www.motortopia.com/cars/1973-datsun-240z-11118/car-pictures/240sx-transmission-swap-14041/DSC04484JPG_Thumbnail1.jpg-27626

Thanks Bill, Leon,

 

Here is small update.

Before fire up engine, I did basic fluid replacement.

 

Engine oil & filter change (5 qt for $15.99 @ Pepboy)
Antifreeze coolant change (10 qt for $14 @ Pepboy)
post-25175-0-35597200-1362416925_thumb.jpg

I bought cheapest oil since this is just testing purpose. I learned that Pepboy mobile coupon is really handy and beat the price from any other auto parts shop.

Next, gasoline change.
Drain 10 years old gas... Oh, man! She pees a lot!

Make appointment for the hazardous recycle.

Buy small portable gas tank and pump fresh new gas at gas station.

After drain oil, I opened up valve cover.

I expected camshaft might be rusted after 10 years.

 

Luckily, inside of valve cover is rust free!

Once thing I'm wondering... My head is N42. I thought N42 has oil spray tube on cam tower, but this head does not have it.

This cam tower could be comes from N47 or later. But is it OK to combine different with them?

Checking cam spec, look for information which cam start having internal oiler.

http://atlanticz.ca/zclub/techtips/cam/index.htm This site does not mention oil hole.

 

I found information that '78 cam comes with internal oiler hole, but I'm not sure "E30" stamp on the cam tells something or not for the identification.

 

I'm not sure just using internal oiler cam with later cam tower works OK or not...

Anyway, pour oil around camshaft, and closed valve cover and pour in rest of the new oil.

Pour in coolant as well.

Pour in new gas too.

 

 

Next thing is ignition check.

 

Swap to new battery.

Check distributor. Compare with 240z, around distributor is so crowded. It much harder to unlock the distributor cap.

Check to rotor, cap, and inside the distributor. It's looks OK condition.

 

Finally, turn ignition on! .......................... does not start engine as you expected...

 

Remove spark plug #1 and put it on the top of valve cover with wired.

Turn ignition to see whether I can see the flash on the spark plug. ...... No spark.

 

OK, change spark plug wire to NGK RC-NE61, and change coil to MSD Blaster 2. I need to order Blaster 2 bracket. original coil diameter is way too big.

 

I was puzzled whether I need to put ballast resistor as same as what I had on 240z, but for 280z, I don't need it.

 

 

I will double check with wiring map later.

 

Turn ignition again to see...

Last night, I check fuel line, whether fuel is coming to injector or not.

 

Following trouble shooting on "280z Fuel injection book" page 37,

http://4moores.com/280z/files/280zfuelinjectionbook.pdf

 

I want to check fuel pump.

In order to hear the sound of fuel pump (actually fuel dumper) I need to disable starting motor.

 

- Unplug shin line connect to solenoid on Starter motor.

- Turn ignition

 

... I can hear the fuel dumper's sound! Good, I don't have to buy another fuel pump!

 

Connect back the line and turn the ignition... Engine start revving!

 

 

 

I was surprise how easy to run the engine that hasn't been running after 10 years.

Since it was late night, I just shut off engine within 2 mins. The cold idle is still unstable, will check it back this weekend!

240z... hmmmmm.... I sold her....

She has two major cancer. Once is floor pan on passenger's side and the other is rear hatch lid.

 

I was planning to mount R200, L28, install fat fuel line... i realized that decent body condition of 280z is much easier to archive this.

 

Then I met this lady and decide to just keep one.

 

Engine is running strong now!

 

But need to work on brake and clutch now.

post-25175-0-07856500-1363191359_thumb.jpg

 

Brake fluid is completely leaked out down to the body and paint under the BMC area is pealed out.

I wonder what is the best way to adhoc fix paint for this area...

Working on rebuilding Toyota 4Runner S12W brake caliper.

One of the piston got stuck and couldn't removed.

 

I got advice from ClassicZ folks to mount caliper tot the Z to pump brake pedal to remove it.


post-25175-0-72476800-1365711164_thumb.jpg

 

I realized that the spacer I got is for 240z and it's too thick for 280z.

Does anyone want to exchange Slivermine Spacer for 280z version with my 240z version?

 

Or I will sell this $90+shipping.

Got all spare 4 suspensions from junk yard.

 

post-25175-0-94700200-1366678985_thumb.jpg

 

I learned removing spindle pins is one of the hardest work for parting out Z.

 

Friend of mine kindly let me borrow spindle pin remover tool.

Based on his recommendation, I got yellow bottle of propane tank and big hammer from HFT.

post-25175-0-85688000-1366696277_thumb.jpg

 

Oh, boy, the 4lbs hammer is really heavy, but it's so powerful!

I was another lucky guy I can just removed spindle just using hammer with PB Blaster!

 

It didn't take 40 minutes to remove both spindles from the spare suspension :icon10:

post-25175-0-78043600-1366696617_thumb.jpg

Next thing is to remove own rear suspension to remove spindles.
