HX35 install

[coolhand_luke]

I was given some Christmas money so I decided to address my turbo situation. I was going to buy a 12cm2 housing for my HC1 but it was too much money for me. I found an hx35 on Ebay for $300 so I decided to go that route. I know its not a genuine Holset made HX35 but Im cool with that. I will see how it holds up. In a few years I will upgrade to a big turbo along with injectors and more, but for now, this cheap HX35 will do. Anyways, it came in the mail and I would give the packing job 4 stars. The turbo came with protective caps on all its openings which was nice to see. Taking my old turbo off was harder than I thought but got her off cleanly. The HX35 bolted on smoothly. Just pushed the downpipe back a bit and it all bolted it up fine. The truck feels quicker with a smooth acceleration. Has a nice whistle too. I need to buy a boost elbow so I can hook up the wastegate. I will update in a few months on how the turbo is holding up. I have some pics of the install but I cant figure out how to post them

A friend has the China knock off ebay hx40 on his VE Fummins, has seen 40psi for a couple years now and no issues. Good luck, looking to do a similar upgrade with my new found fuel

Is your truck intercooled? It might not hurt to throw some sort of screen in the intake somewhere (somehow), just in case the compressor wheel explodes. Intercoolers usually do a good job of catching that stuff but the non IC'd truck will eat anything that fits through the grids.

Yeah, its intercooled. I'm not doing competition or pushing my truck to the limit just everyday driving. I'm expecting the turbo to hold up. I haven't read anything about these turbos failing, just speculation.

I know the search feature blows here, but I know Hineman has posted up where he got his twin stuff. Turbo supply for the turbos. There's numbers floating around for HT3Bs and S475s.

The s475 you posted a link for is what I used for a primary as well, but I got it from http://www.turbosupply.net/ for $552 plus shipping a couple of years ago. It's part number is 171702. The S300g I got was $749 plus shipping at the time, IIRC. Part number 174430. Both of them together were less money than most S300 singles.

Nice little write up but that little dp has gotta be choking that poor engine.

Hello,
I just removed my blown H1C turbo on my 1992 D250 intercooled. I put on a used HX35W turbo. I bolted it up directly to my existing 12cm exhaust housing which has no wastegate. It bolts up fine with just one exception. The outside of the turbo intake (the part that says "Holset"), has a bracket that is part of the casting that sticks out about 1 inch, and this bracket interferes with a tube on the engine. Looks ike the tube goes to a small air tank.

The solution that I came up with is to rotate the center assembly of the turbo, relative to the turbo intake housing. t To do this I removed the large snap ring on the back. Tried to rotate, but would not rotate. When I pulled the assembly out, I found a small cotter pin sticking out from the very outside diameter of the center assembly. I drilled the same size hole (5/64") about an inch away from the original hold and moved the cotter pin to the new hole. Then when inserting the center assembly back into the housing, matching the cotter pin back into the slot on the housing.

The question is, that if I rotate the center assembly relative to the intake housing, does that affect the turbo's performance in any way?

Thanks

You can clock a turbo however you see fit, as long as the center (cartridge) oil inlet and drain stay near vertical...
