Reptoid Overlords

I stuck a screwdriver on the valve cover and listened to the rocker arms from the front to the back. The noise is quite a bit more pronounced when listening with my ear at the end of the screwdriver. Which I imagine is to be expected. I guess I'm not entirely clear on how much louder it's supposed to be when doing that. I've tried to watch all the videos I can find on you tube of these engines running. Some sound like this, some louder, and some quieter. Some stock, some built, some with the text in Japanese that i don't understand haha. If I put the end of the screwdriver on the exhaust runners of the header it isn't all that much louder.

A little over 6k miles on a DSI stage 2 engine with FAST EFI, 14.5 mm o-ring type injectors, 123 Distributor, and a not so great exhaust header. Single gasket. Checked valve lash today with engine cold, followed by re-check with engine at operating temp. All in spec. Stage 2 cam with stock rocker arms, all other valvetrain parts installed by Eiji at DSI. Not by me haha. This video is taken with the engine running post valve lash check after about a 30 mile drive. Honestly, It's always sounded like this. Even before I sent it to DSI. It runs great, makes good power, has great compression and has no known issues. It broke in quick, and I don't beat on it too hard. 4k RPM shifts and 3K RPM cruising speed give or take 500RPM. I have a feeling it's probably ok, I just want the community's opinion. I'm thinking it's a combo of normal L28 valve train racket, exhaust leaks, or simply thin steel used in the header, or maybe a little injector noise. I have the stock o2 port plugged with a bolt, and the EGR port plugged with a big bolt as well. I've moved the o2 bung to the collector further downstream. Been considering doubling the gasket on the header. L28a.mp4

An impressive parts car lineup.

Nice. Were the 2 in Ballard? I never got around to looking. Glad someone ended up with them instead of them going to the crusher. Hauling cars around sure is getting expensive at $5.00 plus a gallon around here.

I was at this show. My friends and I all spent the night at someone's house whose parents we knew wouldn't be home(we were 16)and went into the city to see it.

Yeah who knows. The pictures look to be taken in an area of our city called Ballard. I'm in that part of the city from time to time I'll try and have a look..hopefully it's not in an area too overrun by junkies and thieves haha.

Someone is parting out what are claimed to be a couple of basket case 240's. https://seattle.craigslist.org/see/cto/d/seattle-parting-out-240z/7480076987.html

Looks good. I'm wondering if there's a 125cc kit on that Honda Elite to make it run 70mph on that track haha.

I think with carbs and a big cam high compression pre ignition isn't all that much of an issue.

Here's a handy little web page that claims to have listed all the known non-ethanol fuel selling stations in Canada and the U.S.A. https://www.pure-gas.org/

Are the tension\radius rods from the lower control arms to those brackets on the frame of the car tight? I had one come loose once and caused a vibration, although it became apparent at lower speeds and had a severe pull to the side of the affected loose tension rod. My car is a ZX, but as far as I can tell, the S30 has a similar setup.

I like how you just run the Kuwaiti registration plates. One big difference in Arizona vs. my state. I might make it out of my neighborhood with those before getting puled over and fined.

That wiring seems to be in pretty good shape. My PO put Dynamat over every bit of wiring on the rear deck, including the harness and cover access for the fuel pump. When removing the Dynamat to repair rust, I had to tear up all that wiring and re wire it. I wish I could meet that guy. I bought the car from his ex wife.

I know it was not a problem you were experiencing, but just to clarify for future reference, the slop I was having was due to the shaft/tang currently installed in my car being slightly thinner than it's supposed to be. A spare shaft proved to have no slop.

Jeff G and Zed Head provided good advice when I was exploring stock EFI and more cam. Ended up just going straight to aftermarket EFI. Fast EFI is what I have and it works fine, but kind of wish I had more tuneability. Although your problem sounds like it's somewhere in the harness, and possibly not the ECM/ECU. Just something else to read. https://www.classiczcars.com/forums/topic/63898-lift-480-480-duration-274274-cam-with-oe-fuel-injection/

I hope it isn't this color.

Something about that #2 plug looks like it's getting a rich mixture. Not sure if it's a clue or not but it sure looks too rich to me. I'm wondering if all of the plugs removed would reveal wildly uneven mixtures throughout all 6 cylinders. Perhaps that would tell us something? I haven't quite worked out what all that would mean if anything at all.

The key is getting the torque on the bolts correct. I think the FSM says the torque spec is "tighten it until it doesn't leak"

$2k '72 with some spare parts. Holley carb on whatever engine is in it with maybe stock manifold and head piled in the back with a manual transmission of some sort. Doesn't say anything about title probably doesn't have one like most. https://offerup.co/PskQcoiHQob If I were smart I'd get the 240 and the turbo ZX and for $2500 I'd have the start of a turbo 240

$500 turbo ZX no title. N/A valve cover maybe? Looks like everything is there. If I had room I'd prob snatch it up but I just put a parts car in my back yard haha. https://seattle.craigslist.org/see/pts/d/renton-82-nissan-datsun-280zx-turbo/7464577940.html

I run 15x8 zero offset on the front and 15x9 -15 offset on the rear with 1 inch spacers on my ZX. I have T3 coilovers. It is my understanding that most fitment specs are the same across the S30-S130 range.

On a different topic but somewhat related, be mindful of the slop in the 123 distributor to oil pump shaft\tang. perhaps you've dealt with these already, but in case you haven't, you'll need to shim it up with something to prevent play. It'll cause the car to run poorly. Apologies if I'm yammering on about something you already know.

They are engineering us to look more and more like real humans by the day.

Moose and squirrel will not look at pictures of cars.
