What did you do on your 510 today?

Post by **ostaylor** » 25 Apr 2023 20:21

Cut the tabs off my bumper and installed it on my 72 510. It's going in for a much needed carb tune tomorrow. Hoping for some positive results as there are some performance issues... black around the exhaust output, sputtering under load, blah, blah.

Today I officially had enough of my 510. If anyone wants a project and has the means to ship it from the UK, read through my thread and DM me. Non-running, rolling shell. Road legal in the UK and it will come with a de. registration and export certificate that will make it easier to register overseas. It can come as a rolling shell or with all the spares and parts I have built up over the past 9 years. Open to offers.

Sorry to hear of your decision but you have to do what is right for you.

I watched your thread with some interest when it was active... Your decision must be very difficult. I hope you find someone with the interest and ability to finish a great project. Have you considered contacting Bring a Trailer? Project cars (and 510s in particular) can do pretty well on there. They will work you for a reasonable reserve, but if you believe your market for this car is north America, it will be very good exposure for your car.

It is pretty easy to contact them and submit your vehicle for consideration. I just submitted one with a few pictures and the description, VIN, etc. and they got back to me in a few days. I suggest you look into shipping costs to a few ports in North America - New York, LA, Seattle, Vancouver as this will be a question on the minds of buyers before they commit to the buy.

BaT contacted. Thank you!

Good luck - let me know how it goes. I was able to negotiate my reserve price a bit... There are pros and cons to going with a no reserve auction and they will likely encourage it. The argument for it, is that buyers / bidders know that they will win the car if they have the highest bid and this can promote some bidding wars. They kay with BaT (any auction really) is you need at least two motivated buyers at the end who try to work each other and get caught up in the moment - ask me how I know

Had an issue about a week ago but seems I got it corrected. I was low on gas and was waiting at a light to U turn to head to the gas station. The wagon started to stumble hard and I got out of line and pulled over and the wagon died out and wouldn't start. I was stupid for not keeping my gas can as I was only a 1/4 mile away so called roadside service ( Hagerty) and in a little over an hour they came and put 3 gallons in. Car started but ran like shit. I filled up more gas but was still running rough. Got it to mellow out in the lot and managed to get it home taking street routes. I had a vacuum leak in the past and was able to tighten the intake manifold nuts but think this time the leak was so bad it made it act the way it did. I am running a Rebello motor with Mikuni intake and Carbs It was just the front carb with the issue. I pulled it and noticed there was no gasket and they used RTV and the RTV for cylinder #2 worn away and also one missing bolt/stud on the head which would add to the cause of the leak. During this time I also checked ignition,distributor shaft for play and spark plugs and fuel pressure and all those items checked out. Lucky O'Reilly's auto parts had the FelPro gasket kit, High temp header coating paint and exhaust manifold stud kit. ( also can use a dorman part, or nissan if you can get it or even Honda exhaust manifold studs and nuts they all use 8mm x1.25 thread pitch ) Took this time mask off the engine bay and cleaned the header and painted it. The paint seems to work good and looks a lot better. Cleaned off the intake and head surface with carb cleaner, put two of the studs on the head and cut the intake gasket to line up and installed. I used Honda exhaust manifold nuts as the ones in the dorman kit are 13mm but all my other nuts are 12mm so wanted to keep it consistent. Also used the Nissan thick flange washer to put equal pressure on the intake manifold and header. Got the car running but was still having a miss but no more vacuum leak. Consulted with Dave Rebello and he and I agreed the carbs need syncing and also clean the pilot jets as we came to the conclusion as the situation happend so sudden I may have sucked up some debris from the tank and it got past the filter and into the carb. He said do this and if it doesn't work call me and he can maybe look at the engine for me.

Put new plugs and cleaned out the jets with carb cleaner and compressed air and started the engine and it was running really bad and high idle. Was getting worried but stayed calm and got my sync meter and screwdriver and started to sync the carbs. Was super stoked as I could totally hear and feel the differrence. The carbs prior were 5 kg/h for cylinder 1&2 carb and 9kg/h for cylinder 3&4 carb. I was able to get them all at 5 kg/h and idle at just around 1000 rpm. I left it alone as it was running pretty good and no more stumble/miss. Also noticed the exhaust note was smoother and not running as rich as I used to get black soot coming out the tail pipe. Went for a drive and it was super noticeable. Lots smoother and may have gained back or gained some hp and torque as getting on the on ramp I was able to pull hard and get up to 90mph fast! Brought the car back and tried to fine tune a bit more and idle and response is a bit better. Going to swap fuel filter to a new one and pump in some more 91 octane as I think the person who brought me gas gave me lower octane fuel. Feeling stoked and that I was able to sort this out and get to know the engine better and the carbs/tuning process. Here are some pics for any of you to reference. Sorry couldn't load vids of the engine running.

-Fel Pro intake/exhaust manifold Gasket kit was MS22693-1 $14.49

-Dorman Stud kit #03412 $39.54. Can get individual ones for around 4-5 dollars each

-High temp header paint $14.99

Bought these Watanabe wheels for cheap but the offset was a bit too positive and was close to hitting the coil over perch. Looking at the specs of my SSR wheel ( 14x6.5 +7 offset) and the Watanbe's at 14 x 6.5 +14.5mm offset I needed to use a spacer. Bought two sets of spacers ( 8mm and 5 mm) as they were cheap and trying the 5mm first as that will make the wheel a +9.5mm offset ( Watanabe does make this offset and believe this is the wheel to use on a 510 with stock fenders). Since I am using 280ZX hubs the stock studs were a bit too short so I either had to use longer studs or use extended shank lug nuts. I chose the lug nuts as I didn't want to pull the hubs and install studs but in order to use the extended shank nuts I needed to drill out the lug holes to fit them. I used a Uni Bit which was perfect to drill it for square fitment but it did create a step so used a bit for porting heads and that cleaned it up really well and the nuts fit in clean. Seems i have enough clearance for the coil over perches but if needed I can use the 8mm spacers which would make the wheel offset to +6.5mm which is close to my SSR wheels which I know clears. Right now the nuts do thread in a 1/2" which is supposedly enough for secure mounting. What I like about this method is the shank does make the wheel sit square or hub centric and also that it is an angled seat it is a nice square seat. Just have to do a slow test drive in the neighborhood and check for clearance but pretty confident it will work out.

Finally got the front calipers bled again on the Goon and now no air and good pedal equals stopping power.

Not so much about what I did on my car today, as the engine thread is the extent of what is actually going on with the car. As it is a cool rainy day here I have been tidying up some loose ends on the computer, and few other "odd ducks" that I have not dealt with and need to be put away.

When I retired I brought home 12 tubs of Datsun related bits and pieces. Some are going on the new engine, and I am going to sell hopefully some badges, shift knob, few other things, and, a factory set, in the boxes, complete with wiring harness, the works, rear tail lights. Wow, do they look good! For anyone doing a real resto, these would be stellar.

Also came upon some misc bits of history:

This engine tag was from my 1972 Sedan that got wrecked on the Squamish Highway, now called the Sea to Sky. If you look closely, you can sure see the roll bar did it's job, as witness's said I was 3 feet in the air when I came down on the roof. That's in Specialty Engineering's shop in the early days, on Blackie street.

The paddock pass is self explanatory, such an amazing weekend. We went to the Malibu Gran Prix at night and blew the local hot shoe out of the water with our times.

You may laugh at me in this picture, my white pants....cripes....I'm such a pig pen when it comes to staying clean...what was I thinking!? That was when I stared running the Atlantic front race tires.

The caricatures of my car were done by my sister's partner, the one is not too bad. His first attempt at this type of art work, as he is known on the Island as an amazing pinstriper on hot rods.
