Pictures of my 810 Hardtop

Just re-painted with re-chromed bumpers and door handles, new front and rear glass, NOS grill and headlight trim, NOS taillights and new weather striping all around. I installed a set of new 15" 1984 Z31 wheels with 215/60 series tires. The interior and trunk were completely re-upholstered and new carpet was added.

 

I also added a rear spoiler to the truck lid and I decided to compress the gas shock-absorbers that hold the bumpers on by releasing the gas. I then compressed them fully in and secured them in their fully-in position. This brought the bumpers in closer to the body, improving the appearance of the car.

 

The shocks were replaced with performance aftermarket ones and I discovered that the later Maxima front sway bar was thicker in diameter and bolted right up to my 810. I also cut off a single turn from the front springs to lower the front end by about one inch.

 

I wanted rear disc brakes and I found that the entire rear suspension clip from a 280ZX simply bolted on in place of the 810 rear suspension clip. Very convenient and it also allowed me to use the ZX rear sway bar.

 

For the front brakes I modified some '86-'88 Maxima vented front rotors so they would fit the front hubs and used this combination along with some 1986 Toyota 4-piston calipers. A 280ZX master cylinder and proportioning valve were also installed.

 

I also changed the rear axles to 280ZX CV type and installed a CV type R180 diff. Other modifications include adding the cruise control mechanism from a 280ZX ( I put the interior control unit in where the 810 digital clock originally was) and greatly upgrading the audio system.

 

I am presently working on installing a 280ZX rack and pinion steering setup. The plan is to weld the rack and pinion brackets to the 810 front crossmember. Another 810 owner I know accomplished this on his four-door 810.

 

For the engine upgrade I installed a 3.0 liter displacement engine by boring an L28 block 1mm over and using the Maxima diesel crankshaft, 9mm 240Z rods and milled Z22 pistons. To handle the increase in engine size I will be using the 240SX throttle body, N42 intake and a the mass air flow meter and ECU from a Z31. The L28 block required some machine shop work to relocate the oil sump pickup tube.

 

My VIN is 002536 and the production date is 11/78. It is a five speed. Finding parts during the restoration was always a challenge, but I did eventually locate and purchase another two-door 810 "parts car". Roger Schmidt, at the Z Barn, has several four door 810's for parts as well.

 

I estimate that I have spent at least $5,000 over the last six years on my 810. Sorry to be so long winded :) , but when I start talking about any of my "project" cars I can't shut up! My goal one day is to drive the 810 out to Mt. Shasta (in northern California) for the annual Datsun meet.

The memories! In 1978 I purchased a new 4-door 810 that I really did like. For $800 more I could have bought a new 280Z (still kicking myself). I ended up parting it out in '86 (after a dumb maneuver on my part that caused a collision) to a 240Z race guy wanting the rear end and some other parts off the car. If I only knew then what I know now!

Nice! I'm kicking myself now... I had the chance to pick up one a few years ago, just before I found my 280Z for $300!! The thing had been sitting for about 5 years at a farm behind a barn. We threw some gas down her and it fired right up! Just needed some floor patches and a paint job.. I had thoughts of droping a turbo V6 driveline/suspension/brakes into it.. Oh well.. Maybe I'll find one again someday. :) Nice job man.. enjoy it!

I bought Ernie's (RacerX) 1977 810 a little bit ago with the intention of putting a Turbo L6 in it. Circumstances sent me in a different direction and I just drove the car for a while. A local kid kept bugging me to sell the car to him and I finally did a few months ago. I also sold him a F54 block and a N42 head which is being rebuilt right now.

But it's the AFTER pictures that are truly sweet! Very nice build on a decent platform car. It think it's cool that you found out all that knowledge about the car (what swaps to what). Is the 3.0L all you hoped it would be? Turbo later or no?

 

Nice work!!

Here is some pics I took today of my '79 810

Nice Joe. Those look like the first generation Maxima mag wheels you have.

 

How are you planning to change the L28 engine from a “rear†sump oil pan to the “front†sump pan?

 

One method that I know a few people have done is to cut the oil sump pickup tube in two and weld a short section of thin wall tubing in between, thus extending the length of the pickup.

 

I decided to do it "correctly" and re-located the 810 oil sump pickup tube to the front of the L28 block. If you examine the six cylinder L-series engine blocks you will see that it is cast for either a front or rear oil pickup tube location. The factory then just drilled the corresponding “boss†out depending if it was going into a rear sump (Z cars and Fairladys) or a front sump (810, 1st generation Maxima, Skyline or Laurel) vehicle.

 

You drill and tap bolt holes in the front boss for the new front mounted oil pickup tube and drill a new passage from it to the pickup oil gallery in the block (which runs along side the block). You also have to block off the rear sump pickup gallery with a pressed-in plug and drill a new hole for the dipstick tube at the front of the block (being very careful not to drill into the main oil gallery). Lastly, you need to plug the old dipstick tube. All this cost me about $100 at a machine shop.

 

If you go this route, then I would recommend taking both your L28 and a spare 810/Maxima block (the L24E) to your machinist. Your machinist can index off the L24E block in order to determine exactly where to drill the needed holes.

 

BTW, if you use the diesel Maxima oil pan you can add another 1.25 quarts of oil to the motor as the diesel pan has a larger capacity.

Thanks Davy.

 

I like the low rpm torque of the NA stroker engines (I have a 3.1 liter in my 260Z). The problem with putting a turbo on the 810 is that there is no room for a front mounted intercooler which would limit the boost somewhat. However' date=' I did met someone who had swapped an entire stock L28T drivetrain into his 810 (without an intercooler).

 

It’s interesting that so many items swap between the 810 and the 280ZX. Front crossmember, lower control arms, T/C rods, rear crossmember, driveline components, etc. Since the 810 came out in 1977, two years before the ZX, I like to think that Nissan started with the 810 platform when the ZX was being designed.

 

I’m fortunate to live only twenty miles from the Z Barn. Roger Schmidt has several disassembled 810's in his yard (as well as 200+ ZX’s!) so it was very straightforward to compare parts.

 

Here’s the progress so far on my steering rack installation:

I’m using a spare engine with an 810 crossmember with the rack brackets from a 280ZX in the picture of the mock up. I used the ZX rack to position the brackets before welding. Clearance around the exhaust downpipe will be tight, but possible.

I am loving this thread! I have owned my 810 for over two years now. This is the first time I've seen this kind of interest in them other than the 4 cyl 200B in the UK and Australia. I've got parts lists for them and a 5 page microfiche set that I'm looking into having converted to TIF or PDF format and put on a CD. You guys have answered some questions I've had about these cars. I always thought that they were more ZX based than Z based. Does anyone know where I can get the two plastic pillar mouldings that go inside along either side of the front windshield?

I’ll check the ones in my parts car, Steve. It had a red interior, although they can be painted to match your interior. Since my 810 is garage kept I don't think I will need an extra set. The sun's UV rays can really damage these pieces.

 

Let me know if you need anything else.

 

BTW, have you checked with Norman at OEM Surplus?

Thanks, Steve. If those pillar mouldings are in good shape I am interested regardless of color. Let me know. I've done business with Norman at OEM Surplus/Neosho Truck Parts for some time now. In fact, I just received a new AFM from him today. I've also dealt with Charlie at Old Car Parts, Chloe at Midwest Z when she was around, several other places here and even a couple of places in Australia.

As for an L28E in a 810, couldn't you just get an L24E from a 80-84 Maxima and put a L28E bottom end in it (bored .120)? The'yre plentiful in the junkyards at least around here. You'd be pretty much limited to 2.8 but the only machine shop you'd need is the boring of the L24E block. I have one sitting on my engine stand along with a diesel oil pan but I haven't started work on it yet.

That’s entirely possible. Of course a 3mm (.120in) overbore can be never be risk free. A sonic measurement for core shifting is always recommended before the boring operation.

 

In my instance I had a spare N42 280Z engine gathering dust in the corner of my garage so I decided to use it along with a spare diesel crank to create a “true†3.0 liter engine by going to a 87mm bore. This would be a 4mm overbore of the L24E block. Something I did not want to risk. Where I live the supply of excess L28 blocks is far more plentiful than the L24E.

Beautiful car zcarnut!!! I had a chance to see it a Zdayz, and its much nicer in person. Everyone was talking about how nice it was.

 

Thanks very much for the compliment! I received numerous comments from the Z Days attendees. I also got the “trophy girl” to pose with my 810:

So how are your 810s doing? Mine is still running fine. Just turned 100,000 mi.! I just bought an OEM power antenna from eBay for it. Actually two, one for backup as my original one hadn't worked for about 6 months. Paid $36 for one and $28 for the other including shipping. Both new in original box, never used. It's odd that these showed up on ebay within a week of each other. These have long since been NLA from Nissan but would have cost about $185 each if they had them.

Hello Steve;

 

Good to hear from you!

 

Yeah, I saw those power antennas as well. I picked up my NOS antenna a few years ago on eBay as well. I have seen several on eBay since then and they always get several bids. I didn’t think there were very that many 810 owners. Maybe people think they can be used on other Datsun models(?).

 

About the ZX steering rack swap I was working on: I have discovered a problem. Because the 810 has a tilt steering wheel, the bottom of the steering column is only supported by the recirculating ball steering box. This is done so the steering column will pivot. But when the stock 810 steering box is removed (as part of the swap) there is no support for the bottom of the steering column.

 

So, I am trying to modify an early Maxima steering column (which also has tilt) to fit into the 810. The Maxima steering column has a pivot on the firewall support piece for the column. I suppose I could try to use the ZX steering column but it does not have the tilt function. Until I get this problem solved I won’t waste time and effort with the crossmember swap.

 

.... Just turned 100,000 mi.! ....

 

Just broken in :)

 

My old 24E had well over 200K when I replaced it and even then it used very little oil (and it didn’t even leak any oil either). Nissan sure built some durable engines.

From what I read on another site I visit, Joe (240Ztt) is selling the dark blue one in this thread. Too many projects, not enough time, I guess.

 

Stephen word is spreading fast....thanks again for all the knowledge and parts you let go.

 

 

I actually have something else to focus on besides the Z:
