my friend just got his car tuned by jason hunt tonight, b16 stock bore/stroke with hx40. 424whp @ 18psi. As you know this turbo loves high boost 20psi+ but they were having problems with the timing/stock ignition and didnt want to push it any higher till the problem is fixed.
i know I always interject totally random **** into this thread, here I go again..has anyone done any research into the HE451CW as an alternative to the hx40?
I also have to write my thoughts about this whole idea of decreasing an engine's volumetric efficiency to get a turbo into a more efficient part of its compressor graph. The compressor efficiency graph represents the % of energy going into compressing the air vs heating it. 70% 'adiabatic' efficiency means 30% of the energy is going into heating the air. A higher pressure ratio requires more energy, and even if the % of efficiency in compressing the air increases, the total amount of energy increases, and therefore so does the amount of heat put into the air. I realize that with certain turbos, the % increase in efficiency might come close to compensating for the increased heat normally associated with increasing the PR, but I doubt it would ever exceed it. Another side of this is that with a higher PR, what happens to your exhaust backpressure? And what is your normal ratio of backpress to IM press? More than 1:1. Upgrade your cams, IM, turbo manifold, exhaust, and watch your hp increase.
PLEASE, I know I don't know everything, if there is something I have overlooked in my analysis, correct me..

Cool, thanks.
squad_7, I found a guy on ebay who said he would be willing to do one of those for ~$550. His name on there is bladetwister if I remember correctly.
On a side note I flew up to Sacramento this weekend to pick up my 96dx coupe and my neukin manifold. Tried to fit that hy in my bay today and was really surprized at how much **** I will have to cut out! OMG, like drum said, I will deffinately have to cut the lower driver side mount (@ the block) but because if the strange compressor outlet I will have to cut a lot of other stuff as well. I can't even bolt the turbo up to the manifold much less figure out where to route the charge piping. There is NO room for a filter on the comp inlet, so screen here I come (which can't be all that bad at least it will raise my pr's a bit). Damn this is gettin kinda crazy. Why the hell did I have to get an hy35 for free? I have to use this turbo, after all it was free. What would the "free 99" gods think if I shunned their gift??
Anyone rotate their comp housing. When I took the comp and turbine housings off I noticed that there was a little pin designed to orientate the housings. Maybe I should get rid of my makeshift int wg holder closer and just do a couple of quick hits with a mig to hold it shut from the outside. Then I could cut that little pin and rotate the comp housing however I see fit. What do you guys think?

on my hx35, i ditched the pin so i could rotate the compressor housing, i dont have the issue with the odd discharge that you do, but if it will make things easier do it.

Yup I don't know if I could've got my turbo to fit without a custom mani; that turbo is a monster.
For a filter I'm using a K&N RU-2510; its only 3.5" long.
That pin just pulls out so no need to cut it. I cut the wg mount off my comp housing and put a bolt through my dp flange that held the wg flapper closed.

i had to rotate mine quite a bit...because im a/w i had a lil easier time gettin it all to work...i ran it similar to that of a backdoor intercooler....charge pipiing straight out into the bumper....between the bumper cover and bumper support.....then hacked the other side up a lil bit to squeeze it back into the bay on the other side of the radiator....then into my a/w intercoooler then to tb...all in all about 3' of charge piping vs the usual 5-6'......be careful when rotating the exh turbine...you need to make sure its centered when bolting everything back up....if it isnt it will bind and damage some fins....it will be easy to tell but just be careful....
glad to hear some great #'s on the hx40...hopefully i can come close to those next spring w/ just my hx35 and the bigger motor

So what are all you 'w' housing guys doing? Simply bolting the internal WG shut? I'm taking my hx40w apart to do all the seals, so figured maybe since I'm there, to weld/machine it all shut permanently.. I can get it done by a friend at his machine shop (don't worry, this wouldn't be a slag job at home

Thanks for the suggestions. I prolly wont even rotate the turbine housing at all, just the comp housing.
As for holding the wg shut, check out page 16. That is what I did, many are using different methods. GL.

anyone know anything about the holset h2d? i thought i had a h1c which is similar to the hx35 but from seeing other turbos on ebay, i think its the h2d. will this huge *** turbo ever see boost on a internally stock b20?

no, i was looking at it for my car... but who is that expletive tard bidding it up??
its a t4 flange, but the housing is way way too big for a stock b20

i really wanted a hy35 but i thought i found an h1c on ebay, but the ******* selling it doesnt know that its really a h2d. i just want something that would spool nicely on either a stock b20 or a built ls-v (built block, not head).

I don't know alot about it, but I have a line on a really nice one, I wouldn't mind picking up.</TD></TR></TABLE>
my friend tried mine on an LS while he was building his hx35w, said it sucked.

I had an H1C on my LS/VTEC until the ringlands broke. It ran a 12.88 in the 1/4 at 110 on a bad tune. It spooled kinda slow, but my exhaust housing is in pretty rough shape. It makes good power if you don't mind a little lag. It is the predacessor to the HY and HX series. For the price they work pretty well if you have a ported head.
not the h1c i have, my friend took them apart, and said his hx35 compressor wheel was alot bigger.
i put a 12cm gated housing on my h1c to get rid of the 18.5cm i had before, and i dont think the turbine wheel fits the 12cm housing right. my friend said boost came way later.
he spins through most of second and into third some. he said with my h1c, boost came way later and didnt spin the tires nearly as bad, i dunno maybe he had a leak.
also i must make the statement that my h1c has a 3" inlet and a 2" outlet on the compressor
his hx35 has a 4" inlet and a 2.5" outlet on the compressor.

si i bought this oil feed line from a 92 Dodge Ram cummins
but it doesnt fit the H1C...
..what size thread does the turbo have for the oil feed line???...stealthmode told me i had to find out and tell them...then they could hook me up with a kit....
does anyone know that fitting i need to buy for the oil feed line on a H1C????

My local diesel injection shop has the 2003+ HY35s in stock brand new for $575
Diesel Injection Service in Cincinnati, OH.
The 05+ HE35 that have the HX40 wheel but smaller turbine are closer to $1200.
HX35 are closer to $500 if I remember right.
NEW.
