Check your timing and make sure your valaves are all adjusted to spec. this made tons of free power on my car when I first got it home and brought it back to the factory settings/ Good luck and hope it helps. Dash and tank look great.

Timing is at ~7 degrees BTDC static (idle with the vaccum line unhooked) last time I checked. Dwell is about 49-50 if I remember correctly, I dialed it in to the middle of the range given in the books I've got. I adjusted the valves once (to 0.014" I think cold), but it sounds like one or two might be a bit loose. All the exhaust were very tight when I got it. It does throw out a decent blue smoke cloud when you fire it up, but it clears up in no time and doesn't smoke any more. I think it'd be interesting to do a compression test on it.

Well I actually got around to the compression test today. One cylinder is a bit low, but not too bad. 160-170-170-115psi (1-2-3-4). #4 defiantly has some issue but its not as bad as I was expecting.

 

I also got around to putting a new alternator in. The old one died and I decided to upgrade while I had to fix it. I got a good deal on a used Delco 7si alternator (out of a mercury marine boat) and it basically bolted in. I had to use a spacer on the rear tab but the pulley alignment was perfect! I still have yet to buy the proper connector for it, but it makes good power! 70 amp internally regulated and not much bigger than the 35 amp hitachi. If anyone is interested I'll do a full write up on the install, I took lots of pictures while I was doing it and I have the part numbers as well...

 

My main issues now are cooling (haven't done anything about that yet) and my transmission output shaft seal. I think I've decided to go the Sentra/Pulsar radiator method like is shown here: http://datsun1200.co...diator_Upgrades I just need to get around to calling some junkyards. Around here they close at about 1pm on Saturday and are not open Sundays, how they get any business is a mystery to me.

 

My transmission output shaft seal actually slid out of the transmission, I can push it in and pull it out by hand. This doesn't seem normal... I haven't decided if I'm going to try a new seal or just use some black silicone adhesive to keep it in there. If anybody has worked on this seal before, how tight should it fit?

I'm gonna resurrect my old thread, update some progress I've made on the car.

 

I did some work to it last fall, fixed the transmission output shaft seal, stuffed a sentra radiator in it, and put a b310 distributor in it. The new distributor made a world of difference. It seems the mechanical advance was sticking on the old distributor and the vacuum advance was leaking - big surprise. Then I parked it for the whole winter until I started driving it this spring. I had to put a tach in it since the second speedo I got died, those old clutches just seem to dry up and stick. So now I just run by engine rpm. GPS says 4000 rpm is about 62. Add 300 for 67 and subtract 300 for 57, that covers most of the driving I do. In the last few weeks I've made it my daily driver, commuting ~120 miles a day. The sentra radiator is awesome, running in 100 deg weather and I only kick on the electric fans if i'm stuck in traffic or drafting someone. I've been logging my fuel mileage, averaging about 26.5 MPG and about 500-600 MPQ (miles per quart of oil!  :rofl: she burns a little oil...). I've gotten a high of about 28.4 and a low of about 23.5, not bad for an old tired motor I'd say.

 

Long term it will get rebuilt, but I've still got parts to find. Plus it gets better fuel mileage than my truck.  :thumbup:

 

 

Oh and just cause, a snow covered Datto:

I would love to see the write up on the merc. alternator.

Also love getting 25 plus mpg, these things just sip along.

What year b310 was the distributor out of?

The distributor is for a 1980. I bought a reman one straight from rockauto, they list it under a 1980 Nissan 210 1.4L I4. I also bought cap, rotor, & coil to go with it, 165 shipped.

 

I was a little disappointed in my fuel mileage, I really expected it to be into the 30's. Fuel mileage was my "excuse" for buying the car, but there is room for improvement. Rebuild the motor, 5 speed, EFI, and lower it a bit to reduce drag, should get it up there.

 

I'll do a write up on the alternator when I get a chance, I have to dig through my notes and photos and remember what I did & find part numbers. If you get the right alternator it drops in with only a spacer and some wiring. I had to source a different pulley for mine.

All B310s use the same distributor, and they all pop right into a 1200.  :thumbup:

When did you buy it? When I looked last week they didn't have any. Said I had to send mine in to be rebuilt...     :sneaky:


It's your car, just don't ruin it.


This seems like an elaborate ploy to get me to say "I like the D".

X2. It's an easy swap, you just have to cut the distributor hold down bracket a little to make the late a series distributor fit on an early block. http://datsun1200.co...wer_Distributor

I'm thinking you bought it at the right time...   B)

I'm gonna resurrect and old thread.... Almost 3.5 years and I haven't gotten much done. I did a few odds and ends maintenance stuff - got some new shoes on it. I ordered all the parts for doing bigger front brakes a few months ago - still haven't gotten to doing it!  :rofl:  I just need to win the lotto so I can spend more time working on it!

 

Once I figure out what to use to replace photobucket I'll throw up some pics of the new wheel/tire combo, looks way better with the dark grey steelies IMO - never been a fan of the OE hub caps....

Ok, I got moved away from photobucket. Even went and updated my pics earlier in the thread so they point to real pictures. (thanks photobucket....)

 

And here is how it sits now:
