    Just bought a 521

    Ive got an odyssey PC-680 in the 510 behind the passenger seat and it has no problem cranking and starting the KA. Will be running the same thing in the 620. Previous owner mounted one behind the the bench seat up against the back wall of the cab.
  2. This is inline with what I was reading. I know one of the issues with Dynos is that even with fans, there isnt much air flow through the radiator like being out on the highway so I think that is part of why they want to keep the pulls shorter. Also they may have realized how you drive your truck/what you use it for and felt that a quicker 3rd gear pull better reflected how you drive it and the actual loads your engine receives. Im not sure what the shop would have to gain by inflating his numbers... he wasn't paying them to tune it, just for them to drive it and report on the numbers his engine was making... also not sure I have ever held my 510 at full throttle for 12 seconds- in a 4-5 speed if you held it for that long you would be bouncing off the limiter if you have one... otherwise you would need to shift. I dont think I've even ever held my tacoma (auto) at full throttle that long... well barely 0-60 in the truck is ~7.7 so if we assume 0-75 we are probably close to 10.
  3. Was great meeting up and cruising in! good call on getting there early as we got prime spots! Sorry though as I didnt really take any pictures...... 20191006_105550 by devon M, on Flickr 20191006_105936 by devon M, on Flickr 20191006_114426(0) by devon M, on Flickr' 20191006_104346 by devon M, on Flickr
  4. Decided to go red for Aux gauges--- the speed and tach will still be white, but I think the red will help tone it down. 20191003_183354 by devon M, on Flickr Also picked up a new steering wheel for it once its running 20191003_183746 by devon M, on Flickr 20191003_190156 by devon M, on Flickr Since I decided to rewire it, figured I would upgrade the headlights too--- H4 upgrade for the outer lights, and ambers for the inners. going to wire the ambers on a separate switch to run as fogs. Highs and lows will be on the outer lights. 20191005_140513 by devon M, on Flickr 20191006_181123 by devon M, on Flickr If you look closely you'll see I through some Hella Supertones in there as well.... these cars/trucks are small... so if someone is messing up while driving I want them to know! 20191006_181128 by devon M, on Flickr I was then gonna start working on the wiring... but got side tracked by the nasty "insulation" that was put on the floor.... So I ripped it out.... and bugger these floors are rough..... haven't looked at the back half yet. Driverside- 20191006_164851 by devon M, on Flickr Pass side 20191006_164903 by devon M, on Flickr Then I took the leap! No turning back now. 20191006_172614 by devon M, on Flickr Pulled the wiring harness... and it feels great! While there might not be anything "wrong" with it... although there is... this stuff is so old... and will be much cleaner once redone. 20191006_181142 by devon M, on Flickr Engine compartment cleaned out --- only thing left is the KA engine harness and a few sensor wires 20191006_181114 by devon M, on Flickr Here is the plan for the new fuse box and can am board. ECU will I think be on the firewall. 20191006_185800 by devon M, on Flickr 20191006_181850 by devon M, on Flickr
  5. I dont know about the different tanks... but if the factory electric pump is external then I doubt the tanks are different. Should be a pretty easy swap for you. Remove the mechanical pump and make a block off plate to cover that hole. There are some for sale somewhere for l series engines... but easy enough to make one out of plate or thin bar stock aluminum. Then you just need to install a low pressure fuel pump somewhere in line. There is likely a soft line connecting the tank to the hard fuel line, that's an easy spot to sneak one in. In my 510 i put the pump in the trunk. On my 620 its mounted to the frame rail. Running carbs it cant hurt to put a regulator in there to, and Webers and mikunis can be pretty picky about fuel pressure. A pretty commonly used low pressure pump is available from Carter, then I think I'm running a Holey regulator to dial it in on my 510 with carbs.
  6. So came across something very interesting... the truck in the photo above... IS MY TRUCK! - I was looking at the photo going.... those mirrors are the same, that bumper is the same, those wheels are the same, it looks like the maroon seat is the same... Then I found a copy of the old for sale ad and sure enough there was a VIN posted and it is the same. Looks like it was down in Texas at some point, and the paint looked to be in much better shape, and looks to have had a good clean L series engine in it. Its actually pretty sad... The bed and tail gate are so beat up now... and at somepoint some started to paint it teal... Anyway here are some more photos from the add. 1978-datsun-620-regular-cab-shortbed-texas-truck-rebuilt-motor-new-clutch-7 by devon M, on Flickr 1978-datsun-620-regular-cab-shortbed-texas-truck-rebuilt-motor-new-clutch-8 by devon M, on Flickr 1978-datsun-620-regular-cab-shortbed-texas-truck-rebuilt-motor-new-clutch-2 by devon M, on Flickr 1978-datsun-620-regular-cab-shortbed-texas-truck-rebuilt-motor-new-clutch-5 by devon M, on Flickr Still trying to find a date of the for sale ad....
  7. It would depend on your final ratios... but I did a quick search... bored at work.... sounds like 3rd gear is not uncommon, and is a little easier on the engine, especially at the lower RPMs.
  8. Sounds good to me! Now hopefully I can steal enough time tomorrow to give the car a quick wash
  9. The other big question is... white or red for the auxiliary gauges.... I don't think I can change the speedo and tach since they appear to be sealed units.... but all the other gauges use a replaceable bulb, which come stock with white LEDs. I was a bit worried about the whites being to bright so I grabbed a spare red bulb I had lying around and threw it in one of the gauges.... hmmm.... Sorry for the crappy photos... phone wouldnt take a good one in the semi dark garage. 20191001_175413 by devon M, on Flickr 20191001_175417 by devon M, on Flickr
  10. Its kind of an all or nothing deal for me.... I don't want to keep chasing down issues or have to hack things back together. There are already some missing wires... and a lot of the connectors are literally falling apart... I know its not the "purist" way of doing it... but I already did away with the stock dash so it goes along with the plan of updating things... ___________________ Been doing some digging and the only major issue I forsee if the tail/stop/direction lights... I want to get rid of the stock 620 light switch and use the American Autowire one connected to a relay set up for the head lights --- similar to how I wired up my 510 (I'll dig up that diagram later) --- the rears might be a bit tougher though as the turn signals use the same wiring? I plan to keep the stock 620 stalk for high beams and turn signals--- although I will be looking for a replacement there too since mine is pretty beat up... I guess to simplify things I could split the tailights up... but that wouldn't be ideal... I do plan on running a 3rd brake light up in the window inside the cab, but it sounds like it will be easier to tap into the brake switch at the pedal for that... Hmmm gotta do some more digging.
  11. Well Screw It! I'm ripping out all the wiring and redoing it. I replaced the burnt out fuse I had issues with and charged the battery up. Went out and messed around with it a little bit last night and still having issues with the dash lights, and now I have no tail lights... indicators work though... Could I fix it? Sure its probably only a few wires away from being ok... but its still old wiring and its still messy.... and I am hoping for this truck to be a turn key driver. Fresh wiring is definitely a good step toward that. I did the re-wire in the 510 and while it was a pain I feel like it did clean up a lot of things... and I really like the modern fuse box and the ability to relocate it. I went ahead an ordered the same American Autowire Highway 15 kit I used last time on the 510. It isn't the cheapest kit, but definitely one of the cleaner ones, and even though I won't use most the switches, I will use the headlight switch, and some of their connectors. Its a bit of an extra cost that I wasn't planning on putting into this truck... and will offset some of the other plans further down the road as well... but I think it will be worth it. I think I am going to mount the fuse panel, along with the Can AM box on the passenger side kick panel. I picked up the T3 ones and that should be a nice mounting point. ---- On another note... tired of climbing around the old ratty Datsun steering wheel so I ordered a 14" wood with black chrome one and a Boss adapter with Nissan horn button. I was looking for a Datsun one... but the extra time and cost wasn't worth it... Nissan is close enough.
  12. So spent a lot of time on the truck this weekend... but feel like I got nothing done.... Started at 6 on Friday and worked till about 11:30, then started again at 11-Noon on Saturday and worked till 11:30 again, then again on Sunday started about Noon and worked till 5.... We'll start on a good note though - New Driveshaft! Used Montrose Machine in Wakefield, they had it turned around in 2 days, for a good chunk less then driveshaftshop.com which was alos going to be 3-4 weeks. 20190927_180305 by devon M, on Flickr 20190927_180259 by devon M, on Flickr Got the driveshaft mounted up Friday evening. No photos though... needed some longer bolts... but got some 10.9 40mm bolts with shoulder and trimmed them down to ~35mm and they worked perfect--- might have to do the same on the 510; it has some 12.? socket heads, but I dont think they have a shoulder... can't remember. Friday night I got to work on the dash/gauges and building a wiring harness... As the saying goes... you get what you pay for.... These JEGS gauges are fine... but the Speedhuts are sooo much nicer because of their wiring harness... Start of the harness... 20190925_204936 by devon M, on Flickr Saturday spent a bunch of time messing around with lots of random small things... and finished the dash wiring harness 20190927_233856 by devon M, on Flickr 20190928_175353 by devon M, on Flickr Ran out of light on Saturday, but didnt want to quit... so pulled a blasphemous move.... Kicked the 510 out of the garage and pushed the 620 in! 20190929_194337 by devon M, on Flickr 20190928_183447 by devon M, on Flickr Sunday was mostly a bummer.... the dash harness was finished... and started hooking it all up... and thats where the issues began.... basically spent the day chasing wiring issues.... the harness appeared to be pretty complete.. but has definitely been hacked before... Plus the headlight switch seems to be going out too.... blew out a fuse in the fuse box... and that about ended my day.. still having issues with the gauge lights and headlights/tailights --- head lights and high beams turn on... but tail lights dont work.... Im gonna pick up a few spare fuses tomorrow... but seriously thinking about re-wiring the truck... For the amount of time I spent on the wiring this weekend I could be half way through a re-wire.... Its the old issue of to much shit being removed and now a lot of redundant/useless wiring just kicking around... the swap doesnt help things either... but I havent even gotten to that wiring yet... On the topic of the swap wiring .... I dont know if this truck ever ran... its got a can am box set up... but seems some questionable wiring. Going to pull it all apart and start fresh there..... which makes me think even harder about just going to a new wiring harness..... Anyway... a good photo for the send off... was messing around on my phone and came up with this--- 20190924_230906 by devon M, on Flickr
  13. There are actually 3.... hahaha... another stand alone one across the street from cheese cake factory --- 210 Boylston St #13, Chestnut Hill, MA 02467 --- I say we meet here -- 210 Boylston St #13, Chestnut Hill, MA 02467 -- should be plenty of parking and easy off/on from 9 east. Option 2 would be hammond pond trail and I'll just hit the starbucks ahead of time. Looks like i'll be in the 510... spent the weekend working.... errr dealing with the wiring on the truck and it definitely won't be ready.More on that in my truck thread...
  14. Whatever works for me - but I do like the idea of getting coffee before hand... can't remember if they had some for sale at the show or not.... I can always stop somewhere else on my way in though if we meet by Davios. Looking at the starbucks thats close to Larz Anderson - I agree with crashtest that parking lot is small and could be a bit tight depending on how busy it is. With what Mainer said I think we should get there early... last time I went to cars and coffee there I barely made it in and got stuck down on the hill... yea it took three tries to get up to my parking spot hahahaha....
  15. Registered! Put the 510 down as my vehicle We'll see how the truck goes... hopefully picking up the driveshaft tomorrow AM, and finishing the dash harness tonight. Even if I get it running this weekend though... its the alignment, exhaust and registration that will be the hard stuff to squeeze in next week.
  16. Sounds good to me! Still need to register... maybe ill do that right now. There is a slight chance I'll be in the truck.. but more then likely the 510... just depends on how this weekend goes and if I can get to the DMV next weekend... which is unlikely.
  17. I'll register this week I figured you would be coming down 2 and it looked a pretty easy spot for me to get to. Just a few more exits down 95
  18. That's a good idea... but won't work the handle itself is thinner then the threads. It bumps out at the bottom to fit the tap. I had it lying around and for 8 bucks I figured it was worth trying.... now I have the adapters anyway so I'll keep my eyes open for one of those sapporo samurai handles or something else cool
  19. Thanks! The reach is good. Its mounted to an Ebay short throw with a ~3" extension... but it's just not solid enough.... probably gonna just run the bike grip shifter I got with the truck.
  20. I was looking earlier today. It's not terribly far out of the way to meet out by the intersection of 95 and route 2 or 3. I think I saw a Starbucks out by rt 3. Or we find something closer to the the museum and meet there
  21. Updated the thread title to reflect this years dates.
  22. Once I get in the groove I do enjoy wiring... its just getting over the hump. Its also much easier to do when you have a lot of time and can finish a whole project, its hard to start, stop and pick up again- at least for me. I've got a Carb'ed KA in my 510 that is super fun - you can check out the link in my signature for the build thread on that. A big reason for buying the truck I did was it came with the KA and 2 transmissions. The truck will be stock fuel injection... I'd love to throw some carbs on it, but Mikunis kinda blow the budget. Maybe someday...
  23. Damn... not sure how I got that date wrong--- I think they changed it on me ---- but I'm free that weekend too. I might hold out a little longer before registering.... the 510 does not like driving in the rain... hustling on the truck though so that might be an option, but time is getting tight. Definitely down to meet up ahead of time and try to get a few dattos parked together.
