parts needed for holset hx-35

[dnhieu]

alright im trying to gather some parts to bolt on a HX35 and im wondering what all im gonna need to do so. im wanting to get rid of the gm maft and go 2g mass along with DSM LINK. what size injectors should i get to handle this turbo? my buddy has 850cc i MIGHT beable to get from him at a good price.

what kind of oil lines should i get? can i get the oil supply from the head like it is stock? what kind of return line will i need???

will i need a n/a water pipe? if so will i have to dent it to get this thing to fit?

where can i get a bullseye exhaust side for the holset turbos???

thanks in advance

T3 and Mitsu bullseye housings for the holsets can be found here:

850cc would work well for this turbo I would guess. Your IDC would be getting up ther for the 40, but not too bad.

 

[dnhieu]

i dont think it will be too high with meth injection. also do you think the old walbro 255 will be enough to support the 25psi +++ that im wanting to run?????

Hey, i have recently bought and installed this turbo. U can find a bolt on kit from nick at the turbo trader and that will come with all lines and gaskets. As for injectors 850cc should be fine as long as you arent goin anything over 30psi.

The turbo trader recommended takin oil from the filter housing and it is workin great, no restrictor at all.

Theres not much point in gettin a N/A coolant line cause u will still have to smash it even though there is no fitting there, the amount i smashed mine theres no way around it.

GOOD LUCK
oh one more thing i wouldnt recommend goin internal gate, i have had nuthin but troubles with my internal 38mm gate blowing open. I have a TIAL 38mm external on the way

Ok. Let me get the correct info in here. I ran the HX-35 @ 32 PSI DD. With 1000cc injectors I never went over 66% IDC @ 11.4:1 AFR. Of course when I retuned for 11.7:1 my IDC went down. So a set of 750cc injectors will be more than enough for what you want to run. If you are going to run this with a SAFC you would be best to get 660cc injectors and even then your going to be running a ton of timing advance and not be able to run much boost. Get DSMLink or something to control your timing and fuel properly.

And yes go external gate. The internal gate does indeed suck.

thanks for the replies man. im NOT going to un-restrict this turbo. my buddy messed up his hx40 doing this. do you have a link to the turbotrader where it has the the parts needed to install. how do you guys like the t3 aspect of this turbo? im thinking of getting a threadstone t3 manifold and doing the conversion. how much better is the spool up and such. if not i will just stick with my 2g manifold/ tial combo i have now.

thanks again

The website is "theturbotrader.com" I'm not to sure about the T-3 aspect on it since i am using a MITSU inlet, on a 2G manny.

Spool time is great as i can make 20psi by 3500-3600rpm.

there is the link for further reference. im not sure if the kit comes with a oil restrictor or not. would you know? i guess im gonna stick with my 2g exhaust manifold set up. i can get a kick butt deal on some rc780cc injectors. do you guys think this will be enough to support the 20-25psi im gonna be running? DSM LINK will be here in the next couple of weeks along with meth injecton. do you guys think my unported 2g o2 housing will be enough for this turbo also? or should i step up to something like the evo III???

 

[dnhieu]

another problem that i see is the fact im getting 87% injector duty cycle from my 20g at 21psi with 650cc injectors. are you guys sure 780cc injectors are going to be enough?

 

[TealTalon]

Where are you guys finding the turbo itself? All I see are blown hx35's on ebay.

 

[dnhieu]

this is kind of a funny story. i dont exactly know how it happened but it did. when my buddy was leaving the gas station he got up on it and when i shifted into 2nd and the yoke to the driveshaft broke. well instead of us pulling the driveshaft off we just decided to call a tow truck ### his 1st gen is lowered 2". well the tow truck guy was hardcore dodge cummins and we began to talk turbos and he said he would sell us his old holset hx35 for 75 bucks with only 5k miles on! needless to say my buddy obviously needs a driveshaft pretty bad so i gave him my extra one for the holset. im such a good friend

You can get a BEP turbine housing that has a T3 inlet and the dsm flange outlet if you want a T3 manifold but still be able to use a stock style downpipe.

what is the plus for going t3????

 

[Mike1992]

Going for a replica???

I'd just run it Mitsu since you already got the manifold. I run 780cc injectors and have gone close to 30 psi not hitting 90% idc. Meth injection makes up for about 10% of that. If you plan to feed oil from the OFH use a restrictor, after 4 months with a small restrictor my turbo started blowing some oil. An even smaller restrictor fixed it up nice.

 

[Maglin]

Feed from the Head if you have your BS removed. If you have BS then either head or OFH. Holset recommends no more than 45 PSI of oil pressure. I had mine on my OFH in the begining and now have moved to the head using -4 AN line. It is a considerable amount better as far as the pressure goes.

 

[Steve93Talon]

In this particular case, there is none. The Bullseye T3 housing is identical to the Mitsu version other than the flanges. There is zero gain in flow. Normally, people go T3 or T4 to get a larger AR housing and more choices of ARs to suit their powerband needs. Incidentally, if you already have a 20g why bother going to the HX35? There's minimal - if any - power to be gained.

I'll disagree to an extent. 45psi is not the standard limit. Here's the specs I pulled right off Holset's site for the HX-35 in terms of oil pressure. Read point #13.

psh mines the real deal. you copied me first .

i think im just gonna go with the mitsubishi housing since i found out today i can get one for free. i can also get ahold of the 780cc injectors for next to nothing also. so i guess the only things i need to worry about is the LINK, meth injecton, and oil restrictor because i think im going to run it from the oil filter housing since i already have the line anyways. where are you guys getting the restrictors from?

please explain how there is minimal power to be gained? one main reason for me wanting to switch is because the 20g is getting a little old and tired...

 

[Maglin]

Sorry. I hadn't looked at the manual in some time. Just checked mine and the above is an exact snippit of it. Still under load a minimum of 30psi is wanted. I think I choose 45 PSI as a good operating pressure and that is what is stuck in my head. It's very easy to exceed 120 PSI of oil pressure at the oil filter housing. I believe it best to just take the oil from the head and not worry about your oil pressure so much. You wouldn't have to worry about pushing oil past the oil seal going from the head unless you have some serious oil issues in your motor.

As far as your water pipe. I cut it off just past the water nipple. Then used 4 ply Silicone 1.5" ID hose to attach the ends of the water pipe together and ran it just under the compressor housing. This doesn't hamper the coolant flow into the motor. The 4 ply Hose is rated to 500*F continuous use. It's not likely to exceed that where the water pipe is routed. I just don't like having to dent (crush) the water pipe on this install. If you mock it up you will see you have to really close off the water pipe to get it to fit right. Unless BEP has changed their housings and moved the turbo out some. I have the first run of BEP TH for the mitsu flange.

 

[wt71gas]

You do still have to dent the water pipe even on newer runs which is why it is a lot easier to get a bolt on turbo that is a little cheaper unless you find a holset cheap like $75

Bullseye still sells the housings but thats about it and they no longer even offer it in an internal wategate anymore because there were too many issues. If you are going to run the holset plan on going external wastegate.

If you're runnign a td05H 20G (especially w/ out a clip or an 8cm^2 turbine housign then you certainly are choked up here. Such a turbine and housing is not enough even for an EVO3 16G.

Upgrading to the tdo6H wheel or at least to a bigger turbine housing would help out a 20g set up flowing under around 40 lbs/min. A 20g compressor can support 49 lbs/min. But I've seen but I've not seen or heard of one tdo5H turbine and 7 cm^2 housing come even close to that. . .

An hx35 can flow 0.46 kg/sec at 3:1 PR (about 30psi) according to Cummins Turbo. Keep in mind that the referenced link is discussing the hp of diesel engines not gasoline engines:

Holset HX35

One who is suggesting that a 20g can flow about the same should note: .46 kg/sec = 27.6 kg/min. 27.6 kg/min X 2.2046 lbs/kg = 60.8 lbs/min.

If you are suggesting that a BEP housing will clamp the compressor up, discussing A/R alone will not suffice. Are you suggesting that the 20g turbine housing this person has allows the same flow? How do you know? Are you also suggesting that this person's current turbine wheel flows more than an HX35 wheel? how do you know? I am not flaming, I'd like to see what info or results you ahve obtained. This is interesting.

 

[Maglin]

Matt. I have to correct you here. PR is pressure ratio above atomosphere. So 30psi is about 2:1 PR and 3:1 PR is about 44 PSI.

Thanx! I knew this . I'm tired and ona break from working on a worthless econobox right now. My kids are going bonkers and I can hardly type .

 

[Mike1992]

where are you guys getting the restrictors from?

Cut the flared head off the feed fitting screwed into the turbo and install a sized nitrous jet and voila.
