Tragedy!
We took the van on a 2100 mile roadtrip last week. It and the Bolt are our only four door cars (the dog had to come with us) and EVs aren't exactly great at driving 1050 miles in one day. The drive there was great, except that the volume buttons on my radio have stopped functioning. The Volume Down button sometimes turns the volume down but usually does nothing. Volume Up does nothing. Attenuate one singular time turned the volume down and otherwise did nothing. So that was a pain. But the drive back was the issue. I was suffering a bruised tailbone and the stiff springs were not helping, so we opted to stop in Nashville for the night and resume driving in the morning. That's where the fun began.
Within three miles of our stop in Antioch, the van experienced a hard stutter on the highway and would continue to do so any time it built more than a few pounds of boost. I got off the highway, confirmed that no fluids were leaking and there was no physical damage, and we continued on surface streets trying to keep it out of boost while I puzzled through the situation. I eventually decided that this must be a disconnected boost controller triggering overboost and fuel cut so I hopped the back wheels up onto a curb and inspected.

Sure enough, the vacuum hose had slipped off of the nipple on the compressor outlet.

The nipple isn't barbed and I didn't have any hose clamps, but at least I knew that it would be an easy fix when it happens again. However, I only made it about a mile past that when the turbo blew. The rear of the van erupted in a cloud of oil smoke and any time the boost got above the "3 LED" mark it would erupt again. On the highways of Indiana that wouldn't be a big problem but in the hills of Tennessee and Kentucky I found myself slowing to a crawl to get up some of the inclines. I adjusted our destination to the nearest car parts store (a NAPA) so that I could stock up on oil that I knew I was burning off. 40 miles away. And Google took this opportunity to adjust my settings to allow highways without me noticing. Turns out that NAPA was out of synthetic 10W30 and the Advance next door no longer carried it. I had to stock up on some store-brand conventional, but I guess it would be leaking out/getting burned off regardless. With the destination now set to home once again, Google used its newfound conviction to return us to the highway and took us on the Western Kentucky Parkway. Whose speed limit is 70. Through hills. The next exit was 10 miles away. So on went the hazards and I could JUST maintain 100kph without blowing smoke.
The rest of the drive was miserable. With these horrid springs, the roads got unbearable as soon as we entered Indiana. Our 4 hour return trip extended to 9.5 hours and when we got home I couldn't even walk. I had to have the husband pull me out of the car. The dog hates me. No one wants to unpack the van. We got back on Saturday and I am still exhausted.
So the turbo is blown. I haven't looked into RHB3 rebuild kits but I have low expectations. I could take the opportunity to upgrade to a GT12 but I don't have a way to tune it. And I really don't want to put much money into this SOHC setup since the DOHC swap will be happening and I'll likely just scrap this engine anyway. I don't know what I will do about this, so in the garage it sits. Leaking a little puddle.
Also the bearings that I ordered to replace the steering bushing were the wrong size. My parts order that I placed in April arrived while we were gone. They finally announced the lock set discontinued and shipped me everything else, nearly 5 months later.
In reply to Superairwill1786 :
Every and Scrum vans were offered with tachometers on the PZ, PS, RZ, and PY (Joypop Turbo) trims and the clusters are intercompatible. They're not super common but they do show up on Yahoo from time to time. I don't see any on there right now, though. New from Suzuki they're all around $600 so you're definitely better off waiting around for a used unit. There is a part number change in 1993 but worst case scenario you can swap the tach and combined fuel/temp gauge into your existing cluster along with the plastic circuit on the back. I know that the vans came wired for all of the available features, so while I can't speak for the trucks from experience, chances are good that the connections are already there.
I hadn't really considered restoring the black plastic since it's a work truck for us, but now that the husband is considering selling it (for another Jimny. Again) I might have to look into that. Certainly as-is it looks pretty crappy. I am VERY jealous of the fog lights, though. One of the KS3s that we looked at had selective yellow fogs and I was all over it, but it got sold out from under us and then broke the allegedly brand new timing belt before it ever left the dealer lot. That red valve cover was offered on some of the trucks and commercial vans and allegedly indicates more robust internals, but I have not seen any proof of this. Either way, it looks super cool.
