My non-creampuff daily-driver 510 :)

[rnorrish]

And if you need a better clutch for that 225mm flywheel, once its all lighter and such, the S13 KA24DE one is a good solution.
It bolted up to our aluminum 225mm 240Z just fine for the ice racer.

Problem of the day 8 - the washer pump died.

Well, the original one didn't work so I put in a spare bottle from the basement. Now it failed as well. Go figure! The 40 year old washer pump died. How dare it do that to me! Didn't it know that I wanted to wash my window on the way to a lecture today?

I went to Canadian Tire and bought a SUPERPUMP! I mean a generic replacement washer pump with marketing jargon splattered on its packaging... ...another $20 to the odd altar of antique car worship we all call Datsun.

Canadian Tire didn't have any metal 16" wiper blades. Yay, wiper pump win. Boo, wiper blade fail.

Hi Byron, the term ends as of Thursday evening...

Eh Rob,

Out in Vance's bone yard may be my old red rally car. On it was a set of front 280ZX struts which I machined out the stock strut tube and inserted a tube to use the stock 510 wagon inserts. It had old school Koni inserts installed, and a coil over set up...

Sounds like something like that would fit the bill.

Byron

Do you mean the mustard car or Mark's(?) old car?? How many of your rally cars are over there!?

I'm thinking these struts might be a bit tweaked, somewhat.

Say, there's a set of lug nuts right there with 15" wheels Rob! A little short on sidewayll, but .... I like a 195/60/14 myself ...

[bertvorgon]

That "super pump" is the one I use on my inter-cooler sprayers, been good so far.

[joker72z]

I've grabbed the generic washer bottle and motor from Princess Auto and the pump motor fits like a glove in the stock location. $20 as well if I remember correctly.

[Byron510]

Geez James, is Sahara still there?

It's the Red car, the one that Mark bought from me, then flipped through a few more guys before it got VI'd and parked- that's the one withthe special front struts.

Sahara went out with the coil overs on the cheap up front. The only good thing there was the 250# springs with about 10 hours driving time on them.

Win 9 - Lightened Flywheel, Balanced Flywheel, Balanced Pressure Plate...

The flywheel on my "Craigslist new-to-me" L20B engine weighs a damn ton, approximately 30.3lbs to be a little more specific. Byron said he could tickle a few pounds off it for me, then rebalance it. I bought some lumps of metal and we went to town on it today, making a pile of chips, a balancing arbor (which is stupidly accurate like everything Byron makes), and peeling 10 pounds of mass off my flywheel...

Here are some pictures

^^ Above pic. The rather massive (>30lb) stock flywheel. Note how the iron casting protrudes.

Story within a story... ...the balancing arbor...

^^ Above pic. The main shaft for the arbor, precision turned. (note - I should have bought cold rolled, but I bought hot rolled. Oops)

^^ Above pic. Here it is getting a final tickle-turn between centers.

^^ Above pic. The flange to hold the flywheel. This lump was bored on the lathe, faced, then needed to have the 6 holes drilled. Normally, this kind of precision might not be necessary, but for an arbor going onto a milligram-capable dynamic balancer, this kind of precision makes all the difference in the world.

^^ Above pic. An hour later, six holes drilled and tapped (but they are in just the right place and oh-so-accurately located!)

^^ Above pics. Even though we put three arcs of weld (pun intended) on the back-side, we also left the arbor to soak up and wick a bit of Loctite retaining compound goop for good measure. It didn't need the Loctite, but hey, why not? We were going for lunch anyway...

IMG_1527_800x600.jpg (95.4 KiB) Viewed 2739 times

^^ Above pic. Arbor, finished and balanced to zero. Well, dynamically balanced to something insignificant like 5 milligrams. Excellently accurate, and ready to go! Alright, precision tool made, back to the job at hand...[/color]

OK, so about that ridiculously heavy flywheel... Time to make some iron chips, and a rather large pile of them to be sure!

^^ Above pic. Here Byron magically whisks the pounds off the flywheel as easily as sweeping up crap... No, this is his chip deflector for such jobs - I have one for my lathe, but my lathe is only a toy compared to this big thing! The pounds were flying off, like we were drinking Slim Fast milkshakes with Tommy Lasorda or something!

^^ Above pic. When I was cleaning up the lathe, I found an empty bolts bag so I tried to put as much of the flywheel chips into the bag as I could. Here is what 3 kgs of cast iron flywheel chips looks like.

IMG_1575_800x600.jpg (81.58 KiB) Viewed 2739 times

^^ Above pic. The happy ending. We took the flywheel from 13.8 kgs (a hair over 30 lbs) to just over 10kgs (a hair over 20lbs). Win! The lightened flywheel and pressure plate were balanced to better than 60 milligrams which is fantastic! Win!

Thank you Byron - a nice Christmas gift for me for sure!

Quality craftsmanship guys - nice job!

The last school term was very busy busy for me so not much happened on the car or anywhere else outside of school.

I had a few brief moments to:
* acquire some complete 280ZX struts & brakes, but they still look like old dirty pieces of crap so no picture. When I get into them, I'll post some before and after shots for fun.
* acquire some 6-spoke 280zx wheels; they also need to be cleaned up a tiny bit - again, pics will come...

So, the real reason for this post is the L20B exhaust manifold. What the hell kind of contraption is supposed to connect to this outlet side of this crazy thing??? ANY help would be greatly appreciated. It had to have come from a late 1970s 200SX, HL510, or 620 pickup.

To be pendantic, 10kgs is a hair over 22lbs .... Nice work though!
