Holset Turbo Install FAQ, and Holset Info w/ Maps

    If it's anything like the VGT turbos on the Ford Powerstroke's then it just has a simple .5-5v control silonoid that could easily be controlled by something like a standalone or AVCR.

    Also I just have to whore a pic of my new toy :P

    Thats nice!
    I'm keeping an eye out for holsets. I want to get a rebuildable core for cheap.
    But they are getting more and more expensive. So far I'm seeing holsets that are completely
    screwed…the wheels are chipped/broken and have hit the compressor wall gouging it…or the shafts
    are broken or there are missing parts or the compressor housing is cracked or bashed or twisted all
    going for an average of $200 on ebay. It's pretty crazy.
    I couple days ago some dude listed a BRAND NEW HX35 on ebay. Strangely it was a 1 day listing and
    when I found it the bid was at $87. I freaked. I knew it was worth atleast $900 but all I could possibly afford
    was $200 so I bid that. I was on top until literally the last minute. When for $350 and something like 13 people bid within that last minute. It was still cheap though.

    I'm trying not to get desperate but I need a Holset turbo for my 88T motor :cry:
    I like your turbo though, mnakes me drool

    Babydude, I understand the differences, if you didnt read this thread which is my FAQ, it states the differences between the HY35 HX35 HX40 H1C and H1E. I am well aware of the differences. Yes the compressor flows the same between the HX35 and HY35 however it doesnt matter how much the compressor flows if the turbine housing cant support it. You can make more power on the HX35 than the HY35 PERIOD because of a slightly larger turbine. I was just not impressed with the HY35 dyno i saw, 328RWHP on 16psi. My HX35 would hopefully do close to or more than 400RWHP on the same boost level on a stock longblock. The HY35 is a fricken sweet turbo for the street im not going to lie. The hx35 only spools a little slower and has more room for top end flow and better power on higher boost. And what i have noticed is the HY35 is more popular than the HX35 because it does have a smaller turbine making it very popular for 4 cylinder guys. I see HY35's go for $400 used alot, its crazy. I think a Holset is worth $400 compared to a garrett $600-800 turbo. Its funny though, only a year ago they were like $125 and 2-3 years ago they were going for $60-80 on ebay in GOOD shape, i cant believe how they have gone up so much in price!!! I got my HX35 you see in the pics in great shape for $230 shipped on ebay less than a year ago....

    Yes they are definately worth it! Only problem is I'm so freakin' poor man. I wish they had these in the JY because they'd go for $40-$60 ea. Then I'd rebuild them for myself.
    As far as the prices now…yeah people are catching on thanks to people like you telling everyone :lol: j/k.
    If it werent for you I'd be investing in a stock T3 for my 88T motor so thanks for write ups like this.

    I guess it would be worth it to get one of these so I can go back and get some HX35's for $60-$80!

    Maybe I'll play some lotto numbers while I'm there....hmmm I guess I would be rich then. Which means I wouldnt need the fluxcapacitor to go back in time for cheaper turbos....which means I never would have played the winning numbers which means I wouldnt be rich which means I would still need to go back in time for cheap turbos.... :? someone help me

    That's the HE351 I believe. Great turbo as it's slightly more efficient than the HY35.


    Does anyone know what I need to feed oil into a HY35? I just bought a used a new one.

    Great thread btw.

    get an adaptor to fit the holset threads on the center section with a -4AN fitting on the other end. Connect that to stainless steel line, and connect that to fitting thats a -4AN on one side and the stock nissan oil feed threads on the block which is like 10 or 12 X 1.5. I still need to figure these threads out for everyone, i already run this setup, purely sweet! about $40 for everything locally!

    the stock oil return outlet flange works perfect, bolts right onto the center section and lines up with the oil pan, at least my HX35 did!

    As for the oil drain flange, will any one with 2.0" between bolt holes work?
    that fitting is 12x1.5?

    What is the thread measurements on our banjo bolt on our block?
    Sorry for the wrong info. It is 12x1.5.

    For all you holset guys…hows the space between the compressor housing and the frame?
    Are there any signs that there is rubbing going on down there?
    It looks really really close…like a hairline space.

    Yes it fits, you have to clock the turbo so the center cartridge has the oil drain and the inlet on a vertical axis. The oil is drained by gravity mostly so it it important to have the line pointing directly down. If your turbo is used, it is a good idea to gently separate the turbine from the center cartridge and clean it so it will turn easily when put together and then tighten the clamp. Also the compressor has a large spring clip to hold it to the center cartridge. It might be easier to go to a garage that has a large clip remover. This spring can be a bear, especially if you don't have the right tool.

    That's no closer than mine is. If you're concerned about the movement, get some poly engine isolators in there. They redcued engine movement by a measured factor of three on one modified car.
    Yea I think I will be purchasing some when I install mine one day :wink:
