Could you source some originals, even from a scrap yard, and hone & rebuild or are kits even available anymore? Or are they crap now too?
I've still got the originals in mine... but I probably just jinxed myself...

remember rebuilding them on my 1968 Barracuda back in the early 80s. Not sure what the quality of, or even availability of rebuild kits today.
Is it the metal pitting causing the seals to fail, or the seals just failing???
Ugh..
The things we do, for the ones we love.

Played tug of war with about 15k pounds worth of trash compactor, in a retirement community.... it had blown out wheels, so it was really fun pushing it back in... 4 minutes of tugging, pushing, tire smoking, turbo whining Smokey work. The crowd went wild when I finally got it in! One of the elders came up to me and said “that’s the best show I’ve seen since my honeymoon in 1958”

I just checked the lift pump. I’m now thinking of turning the pre-boost fueling screw clockwise half a turn to see what that does. I just want to try and get the turbos to spoil a little faster as sometimes I get through an intersection before it spoils. I don’t want to do this for a ton of smoke, just a tiny bit more power. I also don’t want to have egts through the roof as I don’t yet have gauges. I’m going to have to order those one at a time. I’ll order the pyro first with a 3 gauge pillar pod (glowshift), and an ISSPRO pyro with color coding for when my dad borrows the truck. Will half a turn make my egts crazy? Right now it is tuned very conservatively by an experienced mechanic on these trucks. I’m guessing egts are low as it barely hazes when I punch it.

Either way, it works out for me. Had it for a few years now, and works great.

That's what I bought, and I'm happy with it. You can configure it how you want it to be, with moving each part of the gauge to the other sector. I chose the outer rim to be the EXH EGT's, and the Fuel pressure and boost inside. Because these units have a dozen colors to choose from by just pressing a button, I can make the color be what I need at the time. Usually, at night, I run the red color, and during the day, I run the green color. I wish they were more "dim-able", but it's fine. Some colors are brighter than others, as seen here with the green chosen.

From that I would get the pod and the pyro. Then I would save up for a trans temp gauge. After that I would get a fuel pressure and eventually a tach. All from ISSPRO just so they match. Again, I have nothing against any of the brands other than I like the color coding available in the ISSPRO pyro. I wish the Autometers had led lighting without getting a white gauge face too. All should have a color coded pyro as an option in my opinion.
Anywho, anyone have an idea of how much half a turn on the pre-boost screw would affect my egts? I’m not doing this for smoke (not really into that), but simply to make it so the turbo spools a little faster. Kind of annoying to be flooring it trying to clear an intersection and THEN have the turbo spool after you’ve cleared it hoping you make it. Not going for smoke, just a little more drive ability.
P.S. Notice how much I repeated the fact I’m not going for a bunch of smoke? In fact, I would be happy with zero smoke. That just means efficiency. Here I go again repeating it. Must mean it is important. I hate people making their trucks pour out smoke like a train. Makes the green freaks whine to the EPA and put pointless systems on the new trucks

1/2 turn shouldn't be a problem if you're not planning on drag racing, full pedal, up a mountain anytime soon. Turbo lag from the exh housing being 18.5 to 21cm is the real issue. Your exhaust temps won't be that high because you're still running the stock exhaust housing. If you put a 14 cm unit on there, without gauges, I'd be worried. Just don't keep on it , full throttle, for long periods of time, as the instant you back off on the pedal, it stops rising, and starts to descend back.
The day I installed the 3200 governor spring, was the magical moment I was hooked into these engines

What size would my exhaust housing be with an hx35? It’s just a stock hx35

Should be a 12cm housing on a HX35. I have a 14cm unit on my truck now and with the NV4500 I think it would work better with a 12cm....or better yet a HE351.
