Im just sick of wearing the outside edge of my tires. Im at 4.5/4.75 at the pinch welds, NB hats, and cant go any lower without high centering on the speed bumps in my neighborhood. Well maybe a 1/4", but yea.

Tire pressure has a lot to do with this, and not necessarily in a way you might expect. I lowered the pressure I run on my current set of RC-1s by 4-6psi (targeting 30-32 hot) and am seeing much better outside edge wear. Apparently, the 36psi hot I was targeting before kept the contact patch too small. Lowering the pressure increased the contact patch but really didn't increase roll-over much if at all. The trade-off is that on hot days I can see some chunking from higher temps with the lowered pressures. So many factors . . . .

<p>I tried it, worked, but doesn't protect from the right UV freqs. My hf helmet broke literally today. So I went out to HD and bought one of the non-auto-darkening shields. I like it a lot.</p>

Why would even attempt sunglasses when the risk is retina damage?
The weld imperfections in the first pic are from impurities in the crack. With TIG welding, clean all the things! Not just the outside.
Not bad otherwise, practice practice.

<p>Because it was funny, and made me laugh <img alt="" src="https://www.miataturbo.net/images/smilies/smile.gif" title="" /></p><p>Yes, I know. Mostly laziness because that is not a high stress part. I need some better wire wheels for my dremel, and a stiffer brush.</p><p>The settings are all pretty confusing, so more research will help.</p><p>I do have quite a bit of TIG experience, (whole manifold) but now that I can do it on my own time I think things will only get better.</p><p>Next up is a master cylinder brace.</p>

Last aluminum weld before the argon left. Continuous, 120amp. It finally blew the 15amp outlet fuse right at the end. Need to use a kitchen outlet next time.

Fuel pressure question.
<br />I kinda want to tinker with my AFPR and whatnot. How exact is the 43.5 NA regulator. Can I just set my AFPR to 43.5 and not need to retune or anything? I also need to install my DW200 but a good AFPR should keep it at 43.5. Of it changed at all it would be richer anyways right?

As for retuning, my guess is that the fuel pressure is unlikely to be completely consistent across the range between the two regulators, so it'll vary a bit. Shouldn't be a big deal, just run the autotune algorithm for a bit.

<p>Well ****, if I'm not AN from the hardline no point in going an at all to the fuel rail. Just need an NPT-an for my fuel rail adapter. Need to see what fittings are on the regulator I got.</p>

Only other options are to flare(unlikely to succeed) it or braze a fitting on.

What do you mean 'routed the same' ?
NB is non-return, so the fuel line routing is obviously quite different. They use GM "push-on" quick-disconnects, which is basically a hard line with a tall ridge at the end. The fittings have a plastic insert that slides over the ridge and then clicks into place, you get them off with a special tool that slides over the hard line and then goes underneath the plastic retainer to release it.
If you really want to get rid of the barbs, it might be possible to put an NB fuel pump bracket thingey into an NA fuel tank.
