Looking good Bo. At one time you mentioned extrude honing the intake... do you go that route?

NARPS valves need cleaning. We do that here for a small fee.

Perfect Justin... that be the bulge I was referring to

The problem isn't fitting... it's replacing the seats with something that actually woks and still fit's.

The best solution I've found for an S30 is early C4 Vette seats (pre '90, if memory serves). Thin backed and heavily bolstered. A fitment exception might be from '74 1/2 on... the tranny buldge might prohibit them. I expect to be test fitting that scenereo this summer. ...36" inseem.

Idle speed is a function of the correct volume of air... matched by the proper amount of fuel and timing. A 'fuel only' method will buy you nothin but trouble.

The adhesive they use is pretty stout... I'm sure it would stick. I probably won't though as I believe the texture will show through. I'm leaning towards sticking it to an aluminum plate and riveting it on... unless someone has a better idea?

Wow. Glad you're ok. One thing that bothers me about the design is the insertion depth of the threaded bung seems overly short. Not implying a longer one would have completely prevented it, but it would seem logical if it were longer and properly fitted, the stresses on the weld might be more manageable. Actual thread engagement might be an issue as well. I would not normally run less than at least 1.5 times the diameter of the thread engaged. Is this area bent?...

I decided to bite the bullet and have an actual sticker made. Signs Now did a nice job, affordably... I designed the label on CAD, printed it actual size, they scanned it and reproduced it verbatim. Doing a single costs a bit... $15 set-up and approx. $4.5 each sticker made, thereafter. The results were worth it, IMO. Testing the waters, I also had them do a small batch of interior window stickers... this could get addictive...

In most cases, you should be adjusting it to run the car properly, with little regard for 'book resistance'. I bet if you spend some time searching, you'll find a good deal of info regarding adjusting AFM's.

2+2 b4?

...and he gave it up for golf

I've done return-less systems a couple times, but they still require regulators. The only way you're going to skip the regulator is by modulating fuel pressure electrically, via the fuel pump. One example is this car... It doesn't appear to be regulated, but it is... its remote mounted.

Drill them out from the front side and re-tap larger for re-assembly.

Best... HybridZ or Zcar.com?

Z32 CAS... look familiar?... . . Tamper resistant screws....

A good way to attack this is what Wolf call's Reference+Sync. This involves running a crank and cam sensor. The crank sensor provides the accuracy, while the cam sensor provides the sync pulse for which event cylinder one is on. For example, running a 12 or 36 toothed wheel on the crank damper with a single tooth on the cam... the single tooth has no direct influence on timing, so it can 'scatter' to some degree, while the crank sensor is providing accurate positional information.

From what I can tell, that one is built identically to the Z32 CAS.

Your story is all too common... welcome to the 30+ year old Datsun.

240 tach is current triggered (pos. side of coil) and 260/280's are voltage triggered (neg. side of coil), as are most aftermarket tachs.

Hang tight... we're discussing it.

Stirring the pot, eh? I'm not in a position to guess if that count and geometry will work with AEM... maybe someone can confirm/deny. Also, functionally, its the same as the one I posted previously... punching a .100" hole yourself saves $30. The hardest part of this mod is getting the wheel out. If its anything like the Z32 CAS, you have to drill out the tamper resistant screws, press out the bearings to remove the disk, re-tap, and re-assemble.... If you're capable of that, you're capable of punching the requisite hole, me thinks.

Thanks. You'd have to add about $500 or so for the Caprice (wasn't much of a car) and add a bit for cost-of-living... I think that car could still be done under $4k, today. Nope, long gone. I don't tend to 'sit-still'. One of my abundant character flaws

Exactly. The manufactures don't give a hoot if you split your block becuase you were too ignorant to use antifreeze. Core plugs are not there for your protection... or theirs.
