I have no idea, can the springs be swapped to alter performance?

I had the same thought, gasket has been replaced, I'm not quite ready to rule it out though as it is the most likely origin, now with a fresh gasket any leak should be obvious.

Haha, funny you say that, many years ago my father wanted a 125, turned out they were too expensive for him and he had to settle for a 1600....

Enough backstory, now for the car. As mentioned, I picked it up over the Christmas break from the family home up north, being that it has been used sporadically I put aside a few days to go over every nut and bolt to be sure the trip back to Christchurch would be uneventful. First up, a few small jobs... Sort the petrol smell: The original rubber joiner had given up years ago meaning the tank couldn't be filled past halfway, a crowd in the west island have reproduced them so out with old, in with the new Then came a tune of the engine, I had been nervous about this as i've never touched SU style carbs, turns out they're easy, plus my learning was made faster by having a full set spare to look at. The engine also has a mysterious click from about #2 or 3, I have adjusted the valves but it still doesn't change, oddly it comes and goes, is mildly engine temp dependant and there is good compression on all four, for sure something that will need more digging..... The eagle eyed 510 spotters will notice the brake master setup is not correct, having be swapped out for a different style for race duties. for now I will run with these until I get the original rebuilt and cleaned up. With mechanicals looking ready for a drive I moved onto the interior, how about the stolen dashboard you say? well as luck would have it, a history of writing off Datsuns racing had left my father with just enough bits to kit the car out as required, he even produced a full set of badges that I now have tucked away awaiting some modern technology for reproduction. The carpet was very much in fine race spec consisting of two or three coats of red paint, in order to prevent my girlfriend from running off halfway back I needed something to muffle the road noise, once again the family parts warehouse presented a front carpet in the most delightful shade of poo brown, matched with carefully positioned black mats to cover the tears a more suitable environment to conversation was produced. Yup, white interior, far better suited to summer! With everything packed and a torn bit of envelope to suppress the steering wheel vibration we headed south, we both held our breath over the Cook strait as the Datsun met salt air and stumbled on start up leaving the ferry, incidentally some muppet had forgotten to fully set the distributor after resetting the timing and had come loose, sorting that we drove on to Marahau for a bbq with Alex and Hannah. On stern advice we reluctantly drove over the Takaka hill, well actually I have been fizzing to do this for a long time and boy was it fun, even with 50km speed restrictions and road works its gotta be one of the best drives in the country polished off with an epic view. And that dumps us back home nice and safe. So plans from here? I was planning on a full restoration beginning this winter, the paintwork is pretty rough from being done for the track but i'm just enjoying driving it too much to take it off the road for any considerable time, there are a few things to start with: The engine tick, it may just be me but I want to dig further just in case I have a side draft manifold and throttle bodies, efi was also on the plans, but SU's just drive so nice and the fuel economy is pretty reasonable. Replace a broken shaft spring on the rear carb - this is causing the idle to not fully drop occasionally, no biggie, but sometimes irritating. Complete the CAD models of the badges and get some replicas made, this way I don't have to cry if they fall off/get broken. Get around to picking up a 5 speed or fit the 3.5 diff in the shed, 3500rpm cruise is a tad loud for my increasing age! Repair the split dash, irritates me a bunch looking at it Paint up a few potential rust spots. Actually decide what colour the carpets should be and source new front and rear Polish up the chrome Clean up the wheels Source new window rubbers so the window trims can be installed. While the list is long of potential performance upgrades, I'm not keen on going too far from factory with it and any modifications that can't be reverted to factory are off limits. Long term it really does need a repaint, but the BRE colours are growing on me and the aged look is reflective of why I brought it, for driving!

More palatable than a rotary I guess

This car has been a long time in the making acquiring, but being the descendant of an original Datsun foamer, it could be said it was my destiny..... The car being a 1972 Datsun 1600sss, the back story? well, take a seat..... 20 years ago the car in question was owned by a young man in Palmerston North, being an easy target it was stolen and taken on a joyride, thankfully once they had had their thrills it was abandoned to be recovered by the boys in blue, but the good luck didn't last, while in impound some scrots jumped the fence and stripped her of all the fancy sss interior, with the badges, steering wheel and dash board gone, there was not much left to identify it as the performance upgrade intended by the factory. Being the Datsun man he is, when my father got word of it being up for grabs he beelined for the impound yard for a nosey, even though the interior had been stripped, the body was in fairly good shape and for a price that we'd all love to pay now, he loaded it onto a trailer and tucked it up under a tarp in the back lawn. At this stage he had a standard 1600 set up as a track car for competing in classic classes at Manfield & car club sprints, but with a teenage family, i'm sure restoration of the sss was still a long way off. Here's a younger me in the 1600 race car in the early 2000s during a carclub motorkhana, most likely the first time I drove a 1600 too! Somewhere in the mid 2000s the race car got close and personal with the tyre wall at the end of the back straight at Manfield, coming out very much second best a donor shell was required, with the sss being in pretty good shape it was quickly fitted out with all the bits and went on to serve race duties for a number of years, thankfully my father realised that sss body shells were getting hard to find and so when a standard shell popped up cheap, he brought that to convert to a more modern safety standard and the sss was reunited with standard parts and retired to weekend road duties. As all this unfolded, I left home, traveled the world, invested heavily in Ladas, eventually to settle in the Datsun capital of NZ, Christchurch. Two years ago the stars aligned on a SAR training exercise and while stocking up on pies in Fairlie, I spotted this wee beaut Sparking a deep down affection I followed it around the corner to where it stopped and of course I started chatting with the owner, turned out its been in their family for quite some time, and the lovely lady informed me that there was a Datsun club and that they had nationals on in Ohakune, even better was that year's theme, 50 years of the 510! Looking at dates they lined up and before I knew it I was hitching a ride north with our very own Datsun barry Runamuck to meet my father and other 510 foamers from around NZ. After a weekend driving around the central plateau I was convinced I needed a 1600 in my life and a plan was struck to purchase a dereg but complete vehicle that was tucked away, sadly after discussion with panelbeaters over the required rust work for re-vin the costs looked a bit daunting for my current plans. A few months later my father slipped up and offered the road legal sss to me, I rapidly agreed before he could back down, only downside was I had no leave left and a work schedule needing much attention, this meant I had to wait until Christmas break to pick up the car! For now it's late, but I shall dig out some more pics and tell more about the car itself and the mini and major plans ahead. Discussion thread here:

Nice pics, is this a return to regular updates with pretty colours and such? Looking at your CFD I can't help think a model of an open ended tube/half bellmouth etc to compare the pressure drop results? In the design work I do, we often look for trends in iterations to make design decisions, confirmation bias is a bitch! For the bend, as you're 3d printing, is it worth throwing an oval cross section in the mix?

Alex was telling me about this project when we called through over Christmas, stoked to see it and hopefully a few more progress updates to come! With a to do list that big, adding the cummins will only take an afternoon at best......

How would a long term table react to a 'bad' tank of gas? would manual reset be needed? I've pondered the same thing but never had to implement it

The same epoxy you made the panel from would be a good start, make sure you key up the panel in the area you're trying to bond and even more sure that all the release wax has been cleaned off

Hows the epoxy benchtop holding up? looking at what to use for mine wondering if there is any benefit from special benchtop stuff over standard resins

Is it a specific one you're after or would you be ok with modifying the standard one to dual cable?

Also, got any further plans/details for your electric car?

A brand new transfer case can be brought from Russia from around $500 usd + freight, keep an eye on TM or ask in the Lada Niva New Zealand facebook page, there are still plenty out there, just gotta find them.

Even a moderate electric motor will have much more torque than the twin cam, you could get tech and monitor the oil temp, that would be the first sign that the loads are too high

Niva box is about 30kg, could be an option, however they were never made with any kind of torque in mind, i'd be interested to know how long they would last behind a moderately powered electric motor

Now this makes alot of sense, have been wondering how you get so much dyno time to swap things out just to see how it goes, good shit!

I weld the bung on first then use that to guide the drill

You didn't drill the hole for the sensor first did ya?

Can you post up the code and circuit as it stands?

its done 5000km +/- and been treated to my experimentation while tuning twin carbs, def not operator error I did wonder if it was blocked, gave it a good cook out with gas and found doesn't react moving in and out of the flame, best budget for a new one

Do report on those tyres, seems they are one of the few options for low profile 13"

Bosch 4.9 sensor failure....... Mine has been a little erratic recently and now gets up to temperature and reads lean, is that a sure sign its poked?
