I'm New to the Sy/Ty world and i want to know if anyone on this board is running a holset turbo. I did a quick search and i found that most people get talked out for using them. All this talk about how there made for diesel truck and that you can't spool them. i want to put that myth to rest. the turbo is design for use with diesel but you can use them on gas vehicles and have great luck with them. the spool very fast because there are designed for use the diesel which burn at a lower temp and slower moving air. Gas burn at a high temp and moves much faster so they spool quite fast. i know this a very poor description on that subject. Is there any other reason that i don't know about you cant run a holset on a 4.3L? I going to try to out on the Typhoon if i ever get it back on the road. In the DSM world AKA: eclipse/talon/laser there are in very large demand because of the spool time and the power out put. the hx-35 has the spool up time close to a 16G turbo on a 2.0L car (ruffly 3000rpms). just imagine the potential on the 4.3L. here is a link to a site with all the info you would like to know about the holset turbos and performance on gas motors.

HX-35-compressor flows 52 lb/min
HX-40-compressor flows around 69lb/min
HX-52-compressor flows around 88lb/min

Not quite sure if they have a lot of different A/R housings for the turbine section?

I run a Borg Warner-inspired turbo (Bullseye Power). They have a variety of A/R's, proprietary race covers, and other things that make them very favorable for use in SyTy's. People on these forums tend to buy units that use the PTE-style housing due to bolt patterns for aftermarket downpipes. Personally, I think these people can make a better decision if they were willing to make their own DP (with V-band flange) and the other mods necessary to running these turbos.

Keep in mind a diesel compression ration. That adds alot to the sool factor 16:1-18:1 with boost is a LOT diffrent than 8.5:1

holset as a brand may not be bad but I dont think taking a turbo off a dodge diesel and putting it on a gas motor will work well

Re: Holset turbos on Sy/Ty??WHY NOT?

Diesel engines also move TONS of air. No throttle plates and a virtually unrestricted intake manifold means lots of airflow, even at idle. Also figure most diesels are (at the smallest) 6L, and many on the road are in the 10-15L range. One cylinder on one of those is almost the same volume as an entire I4.

Your poor grammar already proves you didn't listen in English class so why would you listen to us? :rotf:

Re: Holset turbos on Sy/Ty??WHY NOT?

these are proven turbos on gas motors guys. check out theturboforums.com lots of guys use the HX turbos and put down great numbers.

i know some people who have used the hx35 on 4.3's and they work great. good street turbo with quick spool. like qbnkiller said most guys here stick to the turbos they can easily get down pipes for. there are a ton more turbo options out there (and in my opinion better) if you could have a custom down pipe made

I have a Holset HX40W turbo that I'm planning to drop into the syclone.I'll keep you posted on how that turns out!

Re: Holset turbos on Sy/Ty??WHY NOT?

I have had quite a few cars on the dyno with Holsets on them. And many of them had already been on with Pte, etc. None have set any new records as of yet. More than a few of the owners said the dyno backed up what they already had seen on the street which was a little less than they hoped for. All depends on the setup though.

Re: Holset turbos on Sy/Ty??WHY NOT?

Compressor maps exist and are easy to read if you know what you're doing.

No need to have this discussion - post up the map of the turbos you're looking at and then use the fueling, VE of the engine and the power you're trying to make at the boost levels you're suggesting along with fuel flow and it'll be definitive rather than hearsay and opinion.

There does seem to be a number of people saying that they would work - the compressor map would corroborate that.

Yes i know there are better options out there but for $250-300 for a turbo. you can't beat that. "if you could have a custom down pipe made" any good exhaust shop will be able to fab. one up for you. There's a little one man shop in my town that makes up turbo downpipes. you just have to bring he the flange for it. the reason i brought up the holset turbo is the bang for it buck.

Somehow I have a feeling your going to end up more at the bang then the buck.

How about you list your build before you ask to many questions about a turbo? Because by your main choice in this turbo being the price, and not actual research into other proven turbos. I don't see you having a well thought out build, or rebuild by some other comments in your first post.

Its not only the DP that make people choose PTE, Yes, you can have a custom DP made for our trucks. But its going to take A LOT of fitting, re-bending, fitting again, bending and you might get it right. Its the exhaust housing being able to bolt up to the stock exhaust manifolds, have the turbo clear the AC. Accept and be built well enough to last a good amount of time without a rebuild. And the worry of that $200 turbo coming apart and going through your engine costing you $5k rather then the $900 it would have cost for a good one. Replacement parts are easily available, and numerous options on turbo sizes and styles.

And by your other thread asking to buy a turbo. That doesn't really go with your idea of a budget turbo if you have to buy a used low grade turbo in the first place that you might have to have rebuilt, or chance it blowing up within a few miles of slapping it on.

Just some turbo for thought.

Re: Holset turbos on Sy/Ty??WHY NOT?

the holset turbos are good turbos. just because they can be picked up for a few hundred doesnt mean they are the same crap quality as the china ebay turbos for instance, if buying used then like any used turbo you should budget a rebuild regardless of make

any of these non-syty turbos will require custom work and arent for the person looking to just bolt stuff on. a down pipe isnt hard to make, and there are other creative ways to get these types of turbos to work. i guess i am bias, just about every part on my truck is a custom one-off as i didnt want to be confined to just syty specific stuff

he just needs to know that he will need to have custom work done to the down pipe and perhaps a spacer/adapter to get it to work with the a/c at the least if he chooses to go this route.

I have no build going to yet just saving up the cash for it. Holsets are a proven turbo(1+ million miles) that's why i would like to use one. sorry that I'm not some rich syclone owner that just gives some shop money to build me something fast. just kidding guys but really that is cool that pte is a proven turbo for our trucks but at some point they where a new turbo to the truck and had to be proven. holset has been proven time and time again in the import world. i just want to know what you people that have many years with there trucks would think. i want to get as much info as i can get before is start a build.

sorry if thinking out side the common box here. i would like to take a step in a new direction and you have to test ideas. some times your will fail and you can succeed too, just he chance you have to take. there are around $200-300 because there are used of a truck and there are tons of them out there. more expensive doesn't always mean better. At lest that is what my mother and father always taught me.

As for the down pipe a good exhaust guy would be any trouble for him. you have bought up good ideas for me to think about. thanks for all the reply's. I'm learning a lot and that is what is all about right.

I have a new holset hy35 sitting on the bench, waiting to go in my SVO. The 2.3 Ford guys are making well into the 400 rwhp range with this turbo.:2cents:

Re: Holset turbos on Sy/Ty??WHY NOT?

As mentioned previously, Holsets, BW, etc turbos are viable alternatives to the 67GTQ's, 60-1's, 20g's technology still used by many today. Holset and Borg Warner have invested tens of millions (if not hundreds of millions) of dollars in their wheel designs. While some of them were designed for diesel trucks, they also were used quite heavily in smaller eurodiesels, making them a good alternative for some in this group.

As for the spacing issue with regards to A/C - a $35 eBAY spacer covers that and provides a superior external WG possibility.

Some will drink the Kool-aid of the flavor-of-the-week turbo (or <insert engine/drivetrain component of the month here>), but if some of us dont experiment, none of us would go faster.
