Holset powered Evo IX
 

so after reading through the holset powered evo 7 thread i was very interested in the holset turbos so i did a bunch of research and with the help of revmoto and colonelfox i decided i would try it out... so rev helped me find the holset hx35w on ebay and the seller was local to me so i picked it up then bought a t3 manifold on here for 250 and got to work... all together with new oil feed and return lines and the slim fan a misc parts im into it for about 1000 bucks and it should make over 500 on e85 with a spool about that of a red

then positioned it in the car and saw what i had to fab up which was the o2 housing... very tight squeeze betweent he turbo outlet and the ac compressor

so i started to tackle the hard part first which was going to be the o2 housing... so i got some assorted bends and went to work cutting and welding heres the steps till finished housing
not finished

tight fit sor sure!

bolted up to the downpipe that i had to cut and shorten

as you can see i had to get a slim fan so i made a new bracket to hold the fan and the speed controller box...

this turbo is only oil cooled/lubricated so i had to resirc the water lines
http://i122.photobucket.com/albums/o...1/IMG_0091.jpg

i wasnt able to get a pic of the lower pil retun line now but i went to murreys and they hooked me up with all the AN fittings i need to make a 10an retun line to fit to the factory drain plug... the upper oil supply line was an easy get at murrey also

i have plenty more photos that i will be uppdating soon just have to upload them... the build is complete and the car is running great even though it is untned right now, i also had to make a new licp which i will post pics of later

here is an almost finished pic to end for now

Interesting, ive never heard of these turbos before. Is this similar to a GT 35?

its the turbos off the cummings diseils if i am correct... and no its actually smaller then a 35r it actually flows a little less then a red but for the price you cant beat it

DO you know the exact flow rating?

cant find where i saw it at but is 50 something still trying to find it

that turbo is slightly larger than a gt3076r. and yes they spool up amazingly fast - but not as fast as a red.

thank you for chiming in!

The later model 7 blade compressor HX35 since 1999 flow 60lb/min.

There's a PDF on it at post #8.

You should heat wrap that downpipe and put heat shielding on the a/c comp like the guy in the other holset turbo thread floating around. That's too close for comfort. That's a hot pipe I can't imagine it being any good for the A/c.

So cool seeing Evo guys starting to become like dsmers and actually making **** for themselves rather than just buying a bunch of parts from a name brand place. GOOD FOR YOU!

i do everything myself on this car and make whatever i can, im a budget builder so it def helps doing things myslef haha

thanks for the info but this one is a little smaller then the 7 blade... i have the 8 blade so i get some better spool but less power up top {thumbup}

and i have heat wraped the o2 housing dump tube and sheilded the ac like the guy in the other thread just havent gotten a chance to post thos epics yet

The 8 blade is 56mm, which is slightly smaller than an HTA green.

dude, seriously keep the pics coming, this is awesome. and i would be interested in reading the original thread where you heard about this. a link would be great.

what method (there are several) are you planning on using to keep the internal gate door closed? ive been reading and i like the idea of a screw pushing up against the dood to keep it closed

the original thread is holset powered evo 7 and i just welded the flapper shut and ran an external wastegate... the build wasnt difficult at all i love it and it turned out very nice from my opinion!

you must mean evo 6. all i found was this thread:

https://www.evolutionm.net/forums/ev...ed-evo-vi.html

i dont like the idea of buying a second hand turbo, i wonder if this would work. its not a holset turbo, it appears to be a knockoff. who knows. what i really want is a new hx35

http://cgi.ebay.com/ebaymotors/96-97...Q5fAccessories

Thats an interesting downpipe...

Are you running a divided manifold?

the downpipe is just a megan dp that i had on there and just cut the flange off and rewelded it lower on the dp to meet the new o2 housing i made and the mani is a t3 single scroll mani {thumbup}

a lot of them on ebay are knock offs but sometimes a legit one comes around then you gotta jump on it! haha

Interesting setup.

whats up sean, and thank you hows the tranny doing?

Looks like you had the wire speed too high or you were moving too slow:p

Not good running a divided turbine housing with undivided mani, you will end up with tons of extra heat and stress where they meet.

yeah the welder was acting up, i hate mig need to get me a tig haha but im not 100% sure that it is truely a divided hotside, because the internal wastegate only regulate boost out of the right chamber and the rest dumps right back into the other runner so it seems like a signle housing anyways... im not really sure :confused:

you need to make sure those flanges line up 100% otherwise there will be horrible flow restrictions and egt's will skyrocket also as mentioned above.

yea thank you they are lined up to the best i can possibly imagine {thumbup}

i mean the turbine housing exhaust holes.. they must be 100% with the exhaust manifold or you're going to have big problems. not only is it going to effect spoolup, but its going to kill the turbo most likely due to extremely high egt's cause of flow restriction.

it does not look like they line up and once that exhaust hits a wall big problems are gonna happen.

does it work? doesnt seem like it from the pics...

works great been driving around on it for about a week now... like i said in the post i havent uploaded all the pics already

That press bent (wrinkled?) downpipe looks like it can handle less airflow then stock.. Good luck with your venture.

the wrinkled parts were cut off as you can see in the photo where its bolted up to the downpipe... it is a true 3" exhaust all the way through there

One more thing to watch out for is that these turbos are touchy with oil pressures. dsmtuners.com has a 7 part thread about these on top of a grip of other informative threads;
http://www.dsmtuners.com/forums/turb...-part-7-a.html

the oil lines are correct since he is not running a restrictor in the line as most thought that was the way to go in the dsm world.

yup no oil restictors 3an i believe feed and 10 an return

Wow man, I didn't know you had a thread with you progress. Great work so far. You'll love it when it's done. It's colonelfox btw. :lol:

yeah man its finished and running great not tuned yet but gonna go back and change some things, some people are saying that since the hotside is divorced and its a single scroll mani that at high rpms the egts are gonan spike nasty so im prob just gonna cut away the division! and a few little detail things then its tune time {thumbup}

I have never seen that at all personally. I run the stock hotside with a single scroll mani and I actually run too rich at WOT. No spikes of any kind. I no longer have an EGT gauge but when I did there also wasn't anything like that going on.

oo well thats good news! glad to hear that {thumbup}

This is going to be very sick... subscribed. {thumbup}

bumo for new pics coming this weekend! car has been running great so far minus a small oil leak that will be fixed this weekend and will be grinding out the division to make it a single scroll turbo and get some new injectors and tune that baby!

Lookin good. Nice to see people that still like to diy. My friend has this turbo on his talon and it rocks

I hear you on that turbo. My buddy has one on his sexy Galant VR4 all you chicago guys know who I'm talking about. It is a beast and is the loudest turbo I've ever heard. His car moves like no other. So I know yours will rock. Nice build and Keep posting up your results.

^^i do knnow who you speak of

btw does anybody know how the stock evo9 turbo flows compared to a holset hx30?

im not 100% positive but i believe the stock 9 flows mid 40's like 46ish and the hx30 flows around 52-53 if imnot mistaken will get the exact info later {thumbup}

I think the 8 blade does something like 56 and the 7 blade flows 60.

that sounds about right

looks great!

thank you

That turbo isnt going to last long not using a restrictor. Also the -10 return is a bit small....
Looks good tho

You talking about Milt?

Thats completely untrue. They do not need a restrictor. People were killing them thinking they needed one.

A restrictor is recommended.
Straight from Holset:
"Oil pressure of 150 kPa (20 lbf/in2) must show at the oil inlet within 3 - 4 seconds of engine firing to prevent damage to turbocharger bearing system. A flexible supply pipe is recommended.
The minimum oil pressure when the engine is on load must be 210 kPa (30 lbf/in2). Maximum permissible operating pressure is 500 kPa (72 lbf/in2) although 600 kPa (88 lbf/in2) is permitted during cold start up. Under idling conditions pressure should not fall below 70 kPa (10 lbf/in2)."

At idle the evo runs around 7. A restrictor would kill it there. At WOT I average around 60 and cruise is 50. Its also fed off the head which is a lower oressure then what is measured in the block. Any kind of restrictor would bring it below the very specs you just posted.

nice to see someone else doing a holset on an evo, I should have mine done in a month or so.{thumbup}

Is that manifold for a dsm? It looks as if the placement is not far enough off to the drivers side.

Good to know, my old evo didn't idle that low. Even at WOT it was higher.

I may be off a few PSI because I haven't really watched the guage but it's within spec (I have aggressive cams and no balance shafts) My old DSM's always had higher pressure. The evo has always been around the same with several motor changes and guage swaps over the years.

thank you for the clarity i didnt think i was going to need one {thumbup}

nope its for an evo sits the turbo low and to the passanger side actually but its all good {thumbup}

Buy it now for $330.

Do you think this thing would be way too much lag in an evo? 72lbs/min flow.

:confused:
The 8 blade hx40 does not flow 72lbs, they also dont have vband exhaust housings. Unless this is some sort of modified one I wouldn't trust it, especially from eBay.

This.

I'd scrap that manifold, find one that positions the turbo closer to the drivers side and one flanged for the twin scroll and get a larger better flowing o2 housing. That o2 housing is going to be a huge flow restriction as well as the turbine inlet.

if you read my response to this you wouldve seen that it does not in any way keep the wrinkled portion of the exhaust it was just a mock up and the wrinkled part was cut off just not pictured thank you

yeah i agree i wouldnt trust a new one like that from ebay, i found a used one on ebay that was local so i could check it out... and my hx35 had a vband exhaust flange so idk why the 40 wouldnt?

Got ya, missed that part.

There are quite a few Holset knock offs floating around on ebay.

Excellent job, I'm really happy to see more and more of these turbos making to the Evo world now. They're still a pretty much unknown turbo to the average Evo owner who never had a DSM/Honda, but the potential from them is phenomenal for the price.

I actually have a Holset build as well coming up soon, should be very interesting to see once I have all the necessary little pieces in order. I have a slightly different turbo though, the HE351CW which is a T3 9cm^2 open housing, HX40 7 blade compressor wheel, and a 4" V-band exhaust. I'll be using it on a sidemount/topmount equal length manifold with a 38mm Tial wastgate and 1000cc injectors. From everything I've seen and from the very few compressor maps available it looks to flow around 68lb/min. The DSMtuners Holset threads have some great information about these turbos on there, any quick search will bring it up.
Most HX35's that I've seen are said to flow a bit more than a 50trim, somewhere in the neighborhood of 53-55lb/min depending on the compressor wheel (6 blade, 7 blade, 8 blade). They're a great bang for the buck ranging anywhere from $150-400 depending on size and condition. Many DSM guys now are using the HX35 exhaust wheel and 12cm twin scroll housing with the HX40 compressor to make well into the 550awhp range while still having full spool by no later than 4000rpm.

Sorry, I thought you ment exhaust outlet, my hx40 came with a weird flange, plus it had internal wastegate. Anyways, heres my holset that is currently on my DSM. I have a hx40 with the .70A/R T3 housing

yesssss there are so many i almost made the mistake of buying one also till was told about them haha

oo thats awesome someone else doing it also we gotta get more evos to do this... i spent all together like 600-700 bucks for everything to get this put on including the turbo so you cant beat the price... im excited to see how your set up does with the top mount mani that should be nice! and when time come i plan to switch mine out for the hx40 and make some bigger power.... you going ot be on 93 or e85?

nice pics! thats a biggggg turbo haha ill be there one day! but did you keep the internal wastegate?

I'm going to run 93 octane, probably shooting for at least 25psi depending on how it reacts. I'm going to tune it with EcuFlash to make good use of my Speed Density conversion on the stock ecu, and I have the ability for dual maps in the rom I use so I might even add water/meth to the mix too. Shame I didn't have a built motor, I'd see what I could crank it out to lol. :D

nice! im gonna be on e85 so im hoping for just under 500 but we'll see, got a few little things to fix before the tune and need some bigger injectors

Nope, the wastegate is external. TiAL 44mm

Yes sir I'm talking about milt.

nice! im running a 38mm on mine but my step up to a 44mm soon{thumbup}

Milts a great guy, Ive met him at a couple of local DSM meets.
Awesome :D, you'll enjoy it.

yeah its coming along nicely now cant wait for it to be 100%

What ever happened with these turbos? I'm contemplating going this route and looking for some more info on the fab.

I know it's an old thread but hopefully it can be brought back to life ha.
I just got all the parts to do a unique turbo swap and worried bout the spool time on a 8 blade hx35. With a cast t3 treadstone
Searches are coming up dry.

Can you keep oem radiator+fan and ac and ps with treadstone t3 and hx35?

I do have a aftermarket radiator so when I start fabbing things up I'll give an update. It should be in about a week or two. Have to find the time.

Any updates? I wanted to run a hx35w
