Why the Holset HX35 is the BEST budget turbo! 

Link to T3 housing: amzn.to/3gtL7SG

As a design draughtsman at Holset in Huddersfield UK, I detail designed the HX35 along with the Midrange engineer. It's my baby. Holset Engineering Co. is now Cummins Turbo Technologies, I worked there man and boy for 32 years, my son is still there, it's a great place.

This is great info and exactly what us car guys look for "mo power baby" and still being affordable. That's smart👍

Bro this is a great video, well done 👏🏼

what exhaust housing did you buy and where

I've been running a hx35w... Same one you have since the early 2000s. I recently went from a 12cm housing to a 10cm housing. I was originally going to do what you did but then I'd have to remake my exhaust and I have a Turbo support bracket. And I haven't had an exhaust leak in 6 years. I didn't want to open that can of worms. Anyway, I bought a rebuild kit and a billet compressor wheel at the same time. I've probably got 6 or 7000 miles on it... it's on a 2.8l. Spools around 3k. Sounds amazing it's a 5x5 design extended tip 54x78 Extended tip to 81mm. I highly recommend the bullet compressor wheel. If you're after spool go with a high blade count compressor top end 5x5. I did everything myself and didn't balance it. I run it a 17psi.

So what's your opinion on a power stroke turbo ? Road kill had a 7.3 turbo with a smaller banks exhaust housing and ran it on a stock 5liter ford and it seemed to be a real beast didnt have much lag

Great information.

I’ve got this turbo at home with me right now and I’m wondering should I be able to use this on my truck? It’s a 2011 GMC Sierra 5.3L V8 and idk if it would even work or what

I'm thinking of using a Holset Hx35w turbo on my 5.9 Magnum build...Do you think this would be a good fit?

Nice video, what do you think about put one hx50 in my 351w v8 ford

Hey man. Have a question. I have a 1992 D350 Cummins and I want to do an upgrade on the turbo. What I need to make a 2nd gen HX35 fits my truck.

This has convinced me that this would be mint for my 2.4 l5 volvo build.

Where did you install it? Is there already the video of comparision to GT35?

What sort of spool rpm do you get with the 0.82 housing mate about to build a rb20 with a hx35 I have but want it to spool up good and get boost all the way up in the ramp going for around 450bhp do you think this size would be my best option thansk

did you ever make a dyno video to compare it to Garret? i couldn't find it in your channel

I have a HX40 twin scroll t3 to go on my 1jz GTE, what do you recommend doing to get good spool on it?

So is a hx30 similar to the gt30? And would be more suited to my 2.0 over the hx35?

The Holset HX35 has been the secret budget turbo for decades now. I figured everyone would have found out about them by now. I think if you're laying money down for a brand new turbo, you should buy the best you can afford. If that means it costs $2000, so be it. When you get up to that range, a lot of times the differences come down to things like ball bearing CHRA, which technically might not make a huge difference, BUT when chasing down that last extra bit of power, you really do get what you pay for. I loved it when Cleetus put the ball bearing Precision turbo on his auction Corvette, and seeing how when he shuts the engine down that thing spins for DAYS. I personally have my eye on Forced Performance's Xona Rotor line of turbos. I'd love to try running one of those. That said, for budget builds, you can't go wrong with a quality used turbo. I'm partial to Mitsubishi myself, because I've used their turbos and loved every one of them. My first turbo swap was a used 14b that I bought off ebay for $80 (this was back when the cheapest new turbo was a small 16g for $550, nobody knew about Holsets, and Chinese turbos didn't exist). I was rather disappointed when it arrived because the turbo was coked, so bad that it wouldn't even spin freely. But I was able to take it apart and rebuild it just by thoroughly cleaning it out, no parts needed replacing. The previous owner had ported the exhaust housing as well, so that thing RIPPED! Taking a turbo apart is not that big a deal, just make sure you mark the alignment of everything and put it back together the same way. Loctite that shaft nut or you'll end up with a smooth compressor wheel (don't ask me how I know this)! This is why I love Mitsubishi journal bearing turbos, because they perform well and are super resilient. Even if you abuse them, they're easy to clean and revive. I would buy a used known turbo, like any Mitusbishi or Holset, long before I'd ever buy a new Chinese turbo. Why? Because you know what you're getting, and they're quality precision parts. I think Holset is probably the better way to go as they're cheap, and like you said, they're engineered to last a long time. A Mitsubishi turbo is more likely to have been abused and subject to extreme conditions like my 14b was. But I'd still rather buy a coked up turbo for $100 than spend more on a Chinese turbo. From what I've seen, a lot of these turbos seem to be a mishmash of whatever they have laying around. That might work out fine for you, and they might be assembled and balanced correctly, but it's an absolute crapshoot as to what you're getting. That's not to say that parts made or assembled in China are automatically bad. Good manufacturing CAN be found in China. I know nothing about CX Racing or their turbos other than what you stated in this video, and if they're doing it right, their turbos are probably great for the money. But there's a reason why new turbos cost as much as they do, so I personally wouldn't buy one. I'd rather stick to a known quantity, whether that's a new FP turbo or a used Holset.

Do you have a link to the turbine housing you used in this video? Having trouble finding it. Thanks in advance!

Does anyone know if these diesel turbos are rated at lower turbine speed? That's the only thing I could think of besides the (addressed in the vid) extra big hot side.

Can’t wait to see how it goes! Will you guys offer a whole swap package? Will it be a limited production run?

Totally agree about the hx35. Its pretty much my favorite budget snail. I've used them on a few different builds, my favorite being a top mount setup on a N.V. m50 with a Cometic/ ARP'S running on MS3. Put down around 450whp RELIABLY, and still had quite a bit more to go. These compressors can be had for as little as $100 or so in used condition, and you can get a rebuild kit for around $100 as well. They also come in both I external and internally gated versions. The letters on the end denote that. I believe they are either denoted as a 'Y' or 'HY.' They are also plentiful too which makes them great to use. Good video, some nice info on the Holset. We definitely think alike both liking these turbskis 😎👍

Kind of wish I bought an HX40 instead of the GT35R I bought. I justified it because $1,000 used seemed like a good deal next to the new price, but I could've had the whole setup instead of the turbo alone

Watching this video in 2022 and I'm about to go hx35 on my 1hdfte What's your thought about my plan boss??

Might wanna put a v band on your screamer pipe so you can clamp a little bike muffler on if needed, or have a capped off, v banded hole in the downpipe, and a little pipe to let you take the screamer off and feed it into the exhaust without much hassle. Not sure how it is in the states but a lot of tracks here have decibel limits, and screamer pipes tend to set the drive by decibel meters off like crazy!

Hi bro, which is a good turbo that will match my 4.2L Y60 Nissan Patrol petrol engine ?

Been thinking about putting a hx30 on my 1.8T Avant. Also been thinking about putting a 07k in as well so we shall see what happens Chinese turbos are good for a fun 15k miles or so in my experience but my intercooler hates me.

What size wastegate do you use on the car?

Going Holset HX40 Super or Competition on my 2jz soon. Can get a brand new genuine one for 400$. Can't beat that

I can't wait to see how much power this packs with that 5cyl wail

VSRacing and FP…Robert from forced performance famous for dsm stuff and the creator of zonal rotor etc are both company’s making there own USA assembled budget Chinese import turbo parts right now and impressive is an understatement for the price range. Really like the vid am messing with a couple hx40 hw myself. Boost on bro.

oh man i love holset got myself a brand new holest hx40 super with a #18 twin scroll housing for 500€, but it was 37% off on a swedish website

being a diesel guy (specifically 12 valve cummins) its crazy to me that gas guys love this turbo. for our application on our cummins trucks this turbo is tiny and cant make more than 300hp. for us to make big power normally around 1000hp we run 70+ millimeter turbos

Question trying to do the same going to buy a smaller turbine housing for my garrett gt37....right now it has a A/R .65....what would your recommend. Going to add to a 4cy 1.4

Does it need to be .83 ar or can it be .63?

Very nice. What turbine housing would you recomend for use on a 1JZ VVTI engine?

Saw an ad pop up locally on Facebook Marketplace for HX35 turbos for cheap. I thought he was scamming so did some research only to find out they just are that cheap. Changed my plan to swap a 1JZ into my E36 and going M50B25 with an HX35 instead.

I’m building a Volvo 242 5 cylinder with the same turbo, got it for a killer deal. What ecu are you running?

Hey can you link up where to get this housing. And will it fit any Dodge cummins HX35 and HX35w ? Thanks

@boostbrothersgarage would you recommend for a L6 4.0 (jeep) ?

That HX on a 5 cylinder is going to sound bananas. Big cams, long tubes...yeah buddy!

I will subscribe mate

Do you know if you can mix and match Garrett parts with Holsets?

Do you know a link for the exhaust housing?

3582r is a 62mm compressor wheel... Thought Hx35 were 56mm

I'm in UK and not got round to the turbo yet forged build AGU 1.8t now a 2008cc Stroker with tfis Crank etc etc would this be a good match for my engine thanks great info love ur vids

I have a Golf V6 2.8. Can the HX35 produce 600hp at the crank? or better the HX40?

Can you send me the link for the housing? Cant seem to find one.

Being a smallish turbo, doesn't take as long to spool up either. I've seen these things as replacements for the stock GM turbos on 6.5's, which, let's face it, Holsets are a huge upgrade. Two of these can generate the same amount of boost as a gigantic one, and for an engine governed at 3600 rpm, plenty of meaty boost to work with. I'd say that's where smaller turbos really shine, getting that initial spool up at low end rpm, damn near idle, great for autocrossing, corner acceleration, and of course Diesel towing.

Will the HX35W work as well? Is there a big difference between the two?

where do you accumulate all this knowledge? I have a 944 I'm thinking of 07k swapping with some help this winter. I have been watching this series and have been fascinated by all your knowledge and tricks for a good affordable build Are you a mechanic by trade or just a hobbyest. Keep up the good work!

do you know if this would work for a 08 tiburon 4cyl?

Can i get a link to that exhaust housing

Do u have link that turbine housing ?

I got mine in a garage sale for 20 bucks and it is a very good condition basically brand new the wife sold it to me

Take the silencer ring out. There IS a whistle difference. If you wanted to really go nuts, send the compressor housing off to get a 51r mod. That mod makes the turbo spool sound insane.. turbo labs guy is a turbo genius if you have any questions on your center cartridge.

Hx35 is great . Have a video of one I setup I did with dsm in my channel . My fav budget turbo is slightly more money . 580.00 borg Warner s366. Genuine . But I love hx35/hx40’s ! Great vid . Cool comparison coming . Subscribed !

How much boost are you going to run with that turbo? Im thinkin of droppin one of these into an e30 at 8.70psi, im not sure if this is too big tho.

What transmission are u guys running with this turbo? I heard the 944 na transmission is not very strong.

Good mentioning hx35, it's literally the only Holset worth putting in a car for its value. Other than that one, go Garrett or BorgWarner all day.

Holsets are best,mercedes guys running these all over in europe. My friend has the hx40 on his om606,i have an hx30 on my 1.8 m111

What oil feed fitting did you use for this turbo? I have the same turbo and want to adapt 4an fitting hose to the turbo.

Waiting for Dyno testing like a kid for Christmas.

What happened with the upcoming HX35 G25-660 comparison?

I have a supercharged 3.4L v6 I would like to add a turbo, I have an HT60 is it possible in any way shape or form to run this thing?

On a 12 valve that silencer ring kills all the noise

12 cm turbine is a .76ar, youll also benefit from the twin scroll over the open, the comp wheel in your unit isnt rated that high, still love your approach to what Holset offer.

can you post links

Where are the Holsets made in? And are Aliexpress Holsets genuine or bad quality copies?

Where did the exhaust housing come from?

Is it good for desile 50 hp tactor 2950 cc

can i use any gt3582 turbine housing to hx35?

You know if this would work with the engine in an 06 rx8

I boost this with stock turbine housing to 40 psi on my 5.9 Cummins .

If its got 4 bolts then it sounds like a WH1C off the 94/95 cummins. Same thing as an hx35 just older

Would you recommend for 2010 camaro ss?

I have toyota 2l turbo engine with ct 20 turbo i want to upgrade need more pickup power.which turbo is good for future.

i think full boost before 3500rpm and having 600hp on the same turbo is a bit optimistic

Ebay 110 bucks shipped hx40

The H*Y*35 is the best-kept secret....same compressor wheel and airflow potential as a HX35 but comes from the factory with a single-scroll T3 turbine housing so there's no need to purchase anything additional except maybe a v-band adapter for the outlet ($25-$50 on eBay depending on the size needed); just weld the flapper shut and you're ready to go. Airflow-wise neither of these units are comparable to a GT3582R....that would be the HX40 instead. The HY35 you'll want is only found on 99-01 Cummins-powered Dodge trucks with an automatic trans.

so I heard this Turbo is too small for anything more than 3.0L

While I do agree holsets are the best budget turbos, 600hp is a bit of a stretch for the 8 blade hx35 you have. 500 is about max for the 8 blade. The 6 and 7 blades can flow enough air to support 600hp. Also, gt3582's are like a 700hp capable turbo, so they would be better compared to a 6 or 7 blade hx40, not an hx35.

best for what? when rock crawling with a diesel, you want boost down low and its not needed at 3500 as much.

Well Mike Holly fuck some bargain there look forward to seeing how you get on with it 👍🏻. Yeah the China turbos hard to know if you could trust them and risk making shit of your O7k 😵

VSRacing sells better turbos than CX. The owner Viren stands behind his products 100% and lives here stateside.

I just got one for $50.

So this telling me... Buy 10 ebay turbos and sell it 3x more price and ppl will think hey... This is 1200$ turbo it should last better then 200$ ebay turbo.... Mann... Thanks for advice... Im ordering 3 turbos atm... Hope they sell fast for 1200$ each

Now there gunna be hard to find over 46k people know the secret now haha

dont be telling our secrets, haha. It is indeed the best budget turbo for sure, but by the time you make the manifold, downpipe, it gets very expensive.

So its best because its cheaper than your friends billet ballbearing garrett?

best bugget turbo its a China one ! ahaha

Sell it to me for 500$

This turbo is junk save your money
