    oil supply for a 2nd turbo

    Thanks for all your input!

    Builing a compound set up

    I got a little more done this weekend. the air cylinder that will be the actuator in installed and has the boost line plumbed to it. I put oil & coolant in it and pressure tested the cooling system. No Leaks. Installed the air filter box & intake piping. Re-routed the battery cable down to the starter (that is on this side). Things are getting pretty crowded now. I still want to install these, to cool & filter the exhaust gas that will go to the other end, of the air cylinder to push the VGT open and go to a pressure sending unit, to monitor my exhaust back pressure.
  3. I'm fabricating my own set of compound turbos. My question is, Will it work OK, to put a "T" in the original, turbo, oil supply port? Will that provide enough volume of oil for both turbos? OR should I remove the plug and use the other port that is on top of the filter head to supply oil to one of the turbos? Thanks for your advice!

    That’s a good idea.

    I didn’t know there was a difference between those ports. So putting a T in one seemed the same as using both. ??

    I got to spend some time in the garage during the recent "snopopclips". I started putting things together. As I was wrapping the heater hoses, I wondered if those hare lines were going to be in the way and present an issue. Sure enough they did. The waste gate actuator hit the heater lines and was not even close to lining up the bolt holes. My other concern was that these heater lines were going to be in the way of my final boost tube. So I moved on to installing the exhaust. I braved the icy roads to go buy 7 feet of heater hose. I replace the existing hose and hard lines with new soft hose from the firewall to the block, with some extra to allow room for the waste gate actuator. Then proceeded to continue bolting stuff together. My location marks were not quite right when I reinstalled the compressor housing on the VGT. I had to reclock it to meet the intermediate boost tube. Now, the actuator linkage hit the outlet of the compressor housing. Other than being in an awkward location to work on, this shouldn't be difficult to fix. Used this to apply shop air to the system to check for potential boost leaks throughout the whole system. It worked OKish. When I applied more than about 10psi, the rubber elbow would swell and get out of shape and even with 2 clamps on the steel adapter pipe, I got nervous about it sliding out and the damage it could do. It did show me that I didn't get some of the boost hose clamps tight enough and showed me I had a pin hole in one of my welds. Now those issues have been repaired. I'm ready to move on to the next steps.

    While waiting for the replacement nozzle for the turbo to come, and the seats & floor were out, I looked into an issue I was having, last fall, with the trany being sluggish shifting into high range. I found the equivalent of an electrical relay but for the air on the trany. up on the shifter, are skinny spaghetti noodle sized air hoses, they send air pressure down to this valve that when the spool shifts, it relays a higher volume of air to the cylinder to shift the trany from low range to high. That valve was acting sticky and sluggish. I took performed some exploratory surgery, cleaned up some gray sludge, lubed it up, re-assembled it, charged the trucks air system with shop air, and it is working perfectly again. While the seats are out, I ran some wiring and installed a new boost gauge, a 2nd one, to measure pressure between the turbos. I painted the cold pipes, compressor housings, and brackets, put header wrap on the exhaust pipes, put some reflective, foil backed insulation around the AC receiver tank too. The new nozzle for the turbo arrived, I re-assembled the turbo, and finished making the air cylinder actuator brackets. This is in the closed or exhaust brake position. This would be in the wide open or bypass position. It is feeling like I'm getting close, all the "hard to figure out" stuff is done, now it will be pretty much bolting things together.

    Sweet, that is close. I live near Huwy 512, at the canyon rd exit and work in Fife.

    Help! While making linkage for the VGT, I hit that actuator foot with a punch, planning to drill and tap holes in it to secure a bracket to it. That seemed to be really hardened, so I just welded it together. it looks like when I hit that foot, I broke one of the stems, that raise and lower the nozzle ring. Being Saturday afternoon, no turbo shops, in my area are open, to even check on availability of this part. Ebay shows a few for sale. I'm shocked at the price they are asking. They start at around $225 bucks for one that is in the USA, or a little cheaper if I want to order one from China. Do any of you have, or know of, a used HE351VE turbo that you are willing to sell that ring out of? or sell the whole turbo?

    Thanks Hoss, for offering your place again this year! I'll start negotiations with my wife, to see if she is willing to spend her birthday at this gathering.

    I finished connecting the final exhaust from the lower turbo to the existing 5" muffler. This view is from under the right front fender with the plastic inner fender removed. This is the same route the exhaust ran before (since the tranny installation). Now it was time to take everything back apart to paint some parts, heat wrap others, install blankets on the manifold and turbos and put it back together with gaskets and bolts that are properly torqued. Since the manifold and HX35 are divided, I shaped and installed a divider plate in the waste gate spacer, Wanting to allow pressure from the other side to cross over, I put a hole in my divider plate. I still have to make up new mounts for the air cylinder, I use to control the VGT, but that can be done with the turbo out and on the bench. The way I had to clock the compressor housing for this project, put the outlet in the way of the previous mount set up.

    I know a lot of people trash talk these air filters and boxes but I have not been able to prove it is inadequate. A few years ago, when I had my truck on a dyno, I ran one pass with this air box, let it cool, and another pass with no filter or lid on the air box. There were no changes in smoke or power. I keep an eye on the filter minder and have never seen it get pulled down, when towing hard, unless the filter was dirty. Another thing, is how much I don't like or trust washing filters. The possibility of getting some of the filtered dust around to the clean side of the filter. Then there is also the opportunity to put small tears in the filter element.

    Moving on to installing some of the smaller, stock parts, I hit another snag. The stock waste gate actuator for the HX35, wouldn't go on because it was hitting the new intake track. Several hours later and several failed attempts (such as slotting the mounting holes to allow this bracket to pivot) to overcome this issue. Fortunately, I had a second mounting bracket to use. The end result was a shortened bracket with the end welded back on, re-drilled mounting bolt, holes, which then required the actuator rod to be shortened and the adjustable end to be shortened and threads tapped farther down. If this was an easy project, I wouldn't have been intrigued by its challenges.

    I have made some other progress. I worked out the intake track from the air filter to the bottom turbo. Now I could see there was not going over, under or around this intake track for the final boost tube. OK, over the injectors it is. It did require a 90* boost boot at the inlet to the air to air, so this tube can come up in front of the lower radiator hose. I also installed a bung to thread in an air temperature sensor in this tube. With all the home made pipes completed. I took them back out and welded rings around the ends. then hit them with a flapper type of grinder disk to remove and high spots, and any sharp beebeees. This will help the boost boots seal and keep their clamps from slipping off.
