carterb Posted August 10 Report Share Posted August 10 Had to get a new fire system. When I sent our old bottle in for inspection ( you have to do that every 2 years ) they said there were two little dings and a bend in the handle so they couldn't recharge it. Nothing to do but bite the bullet and get a new bottle. Of course the old one is no longer supported so I had to get a new style. Which takes different hose and nozzles. We sure love racing don't we boys?! 2 Quote Link to comment

datsuntech Posted August 14 Report Share Posted August 14 Not sure if you mentioned it before, but can you share some info in that engine rack in the background? Seems like an efficient way to store a bunch of engines. Quote Link to comment

We sure love racing don't we boys?! I put in that same system last year, as mine was quite old and no longer serviceable. It's pretty nice, but as you said, I had to remove everything existing and run all new lines, etc. Thanks for the reminder on service check. I may be due end of this season. Quote Link to comment

Seems like an efficient way to store a bunch of engines. I got some 4x4 steel out of the recycle bin along with some linier rails. Then bought and machined all the parts to hold the engine stand mounts that hold the engine. It was a ton of work. Back when I was a young guy I went into a shop and saw a similar thing. From then on I always planned on building one. Mine is fancier then the one I saw way back then 🙂 It was funny when I loaded the first motor on and it was hanging out way up there all by itself it was scary to get close. Once it was fully loaded it wasn't, weird how the mind works. 2 1 Quote Link to comment
carterb Posted August 16 Report Share Posted August 16 (edited) Last week we introduced the K24 to its new home: Then for some reason we decided it would be a good idea to rewire the whole car! Lots of things to ponder Like - did Ziploc steal our paint scheme? And does our 510 have "Grip 'n Seal Technology"? The K24 swap has so many follow-on affects... We need a new water temp gauge because Honda uses a different thread than Nissan for the temp sending unit... There *may* be an adapter but we're committed now. Scratch that - getting an adapter. Wednesday we got a good start on wiring. I didn't take any pictures. Can you believe it?! Edited August 16 by carterb 1 Quote Link to comment

Most of the weekend it was up in the air getting attention from mechanics. I'm afraid I didn't get a photo of it. I stole this from someone else at the June race @ PIR. It was still in the same position as I last saw at the Ridge. Hopefully they got the issues sorted and enjoyed a weekend of racing. I still haven't posted my photos from the April race yet but here is the NSX. 2 Quote Link to comment
carterb Posted September 12 Report Share Posted September 12 Uh oh! Running out of time. Let's see how fast I can get us up to speed... Back in mid august I set out to redo our windshield defrost system. Timing was good, the old fan plenum just about disintegrated upon disassembly. I started by making a model of the fan motor and interface flange: Then modeled this Tri-Y outlet plenum: Nice to have this done in an evening but Jeff said it wasn't "fancy" enough... Okay then! Challenge accepted. More on that later. Couldn't hit print just yet anyway as I was unsure if I had matched the old tube interface dimensions correctly. If you remember, one of the other things on my list was to adapt the coolant temperature gauge to the K24 intake. The sending unit on the gauge is comprised of two fittings. The outside fitting is 1/2npt but we need M12x1.5 I reached out to Autometer and they understood my situation and told me the part number of the adapter I needed to buy from Summit. (Apparently this same issue affects the LS guys) So I followed the link and purchased the adapter. Great! Except that it is not great. The internal thread is not correct AND there is no taper to bottom out the temp probe body against. It turns out that I was also supposed to buy an adapter directly from Autometer but that was left out of their response. They kindly dropped one in the mail to me. Fingers crossed at that point! Next I turned my attention to the radiator mounting as the hardware we used in the '68 won't work on the '71 since the '68 has a flat bottom core support and the '69+ cars had a dipped core support. (possibly for automatic tranny cooler radiators? Does anyone know?) These next photos won't make sense to anyone but are included here for posterity. 13/16" core support "dip" And a quick look at heater hose routing for the new defrost fan assembly (I cut off the dangling radio mounting tabs) Am I going to have room for all of these temp gauge adapters? 1 Quote Link to comment
carterb Posted September 12 Report Share Posted September 12 Speaking of adapters, how are we going to finish mounting this fuel rail? It is currently only supported on one side and we need to make sure all the fuel goes in the hole!!! sketchy sketchy - measure measure model model - printy printy And they were ready to install the next time we go together! Perfect fit! In the mean time, Jeff and Paul were working on wiring and many other activities when someone realized, we had never disconnected the battery in Swamp Thing! (disconnected was default on the Gobstopper when we were testing all of this) Paul loosened the seat so we could get the top of the battery box off. Turns out the positive battery terminal has been growing its own kind of swamp thing I made a flywheel cover It doesn't seem like we are knocking off many things on this list and we are only about 2 1/2 weeks away now! Another evening of model model - printy printy - does this revision look fancy enough Jeff? Jeff says yes! (and that was before I added the fillets) 1 Quote Link to comment
carterb Posted September 12 Report Share Posted September 12 When we're not working on the racecar, we're working on the racecar trailer. I brought the fenders home to advance their state in between our weekly racecar sessions. weldy weldy painty painty I was down and out sick for the weekend but I had enough energy to finish these off. The autometer adapter arrived! And it fit! Our only rule - no leaks! 1 Quote Link to comment
carterb Posted September 12 Report Share Posted September 12 By this time we are one week away and for some reason, we seem to keep adding things to the list instead of marking them off. Paul noticed that our rotors had an array of stress cracks. (you can't see in this photo - I'll try to get a better one later) We went to the shed to find a pair of back up rotors just in case. Work on the car had been so frantic over the last couple of weeks I didn't keep up with photos very well. After we got most everything mechanically installed - In the process of installing the drive line and tightening all the bolts on the rear suspension we found that the tranny was locked up. It would only shift in to 3 of the six gears. We ran this tranny before and couldn't find or think of anything obvious to fix it in place. It would have to come back out. We had the spare tranny from the Gobstopper right there for comparison and it worked fine. No idea... The cool thing was that we dropped the tranny in about 30 minutes - with the SR it took about 2 hours because we had to lower the whole crossmember and disconnect the steering etc to get the room needed to make it possible. With the tranny on the floor and separated from the bellhousing we were unable to replicate the issue and we convinced ourselves that somehow one of the selector shafts was bound so we carefully put it back together and test - shifted the tranny on the garage floor and it seemed to work fine so back into the car it went and that allowed us to finish up the rear suspension and exhaust and everything else under the car. Monday we aborted the redesigned 3-d printed radiator mounts as they were still in the printer and we needed to get this thing done. We fabricated some Z brackets for the sides. That allowed us to finish the radiator install and the car was running by now as well. "only" the details remain right?! Yesterday we pretty much finished everything on the list The major re-wire and re-plumb left a much much cleaner looking interior! JBC custom switch panel! Relocated heater with new "fanifold" I think Jeff's calling to make sure his AAA membership is still current. : P First drive!!!! https://datsun510.com/uploads/monthly_2024_09/09102024swampthing(1).MOV.c902e2fd52e27777597860278c7e0e70.MOV https://datsun510.com/uploads/monthly_2024_09/09102024swampthing(2).MOV.d9af8e565f912723cbaf33bf74dcedd4.MOV "SO WORTH IT!!!!" The drive uncovered a conflict between the exhaust and the drive line - quickly remedied by a little exhaust mount shim. I had the privilege of taking the next test drive to re-check our work. Man this motor revs! And makes a lovely sound in the process. Look out Ridge - ready or not - here we come!!!! If you are in Shelton this weekend, come by and say hi. Look for #71 on the tent full of old exhausted Datsun enthusiasts. 4 Quote Link to comment
shlammed Posted September 12 Report Share Posted September 12 just for what its worth, the k series intakes only run fuel rail brackets on one side. is the s2000 different? Quote Link to comment
Icehouse Posted yesterday at 05:11 AM Author Report Share Posted yesterday at 05:11 AM Great weekend of racing! Friday practice went well. Only issue was reported by Carter. He missed a shift and had a hard time finding any gears again. We thought maybe it was the slave cylinder getting to hot because it's next to the exhaust. We stole some NASA heat sheild from the Acusump feed line. Saturday it rained a bunch. I enjoyed my stint in the rain. Car was handling awesome! Sunday was a perfect washington day, partly cloudy and dry. These are the only photos I took. We all broke our lap records. One thing we would like to change is get our 4.44 gears back in the car. The 4.11 are way to tall. At almost the end of the straightaway we were at 4th gear redline and 116mph. SO FUN!!!!! 5 Quote Link to comment
