hey everyone, just been reading about holset turbo's and from what i can see 99% of the review are good, and they dirt cheap. you can get a turbo similar to a gt30r or 35 for like $400...
just want to see what anyone here knows about them and if any1 has used them or knows of some1 using one
just gathering info
they are good turbo's from what ive seen.. they have wide aplication in industrial and agricultural machinery, they are def not like chinese knockoffs 8)
the more i look into them, the more promising they look, i would like to see if any1 here in S.A has used one. i think that any1 looking into getting a turbo upgrade should consider one...
where is the info about them being comparable to the GT30's?
Im in the market for a GT30/76, need it within the next 6 months..
need one of those 30s this week!!

sh*t sorry, dont know exactly where i had seen the comparison, was just searching on google and a whole lot of forums etc, search for the holset hx30 or hx35 turbo's and look at the specs, very similar if i remeber correctly, i'l have a look again and see if i can find it
if you search around and google holset turbo specs and reviews, you can find out quite abit

Be our guiney pig bru!! 🙂
when it comes to the time i think i mite
just not there yet...
oh ya one thing, the holset is journal bearing not ball bearing like the garret...
there so many forums and such talking bout holset turbo's, i think it would be best to just google
truck turbos, LOL, if you want to use a cheap one then rather look into Borg warner turbos, if you have the extra money then the Bullseye (modified borg warner)
I was told the Bullseyes are the next best option!
they are pretty good, specially for the price.
whats generally is a good, most importantly reliable option other then garrett?everyone with experience in their opinion.
hehe.. aint nothing in this world wrong with truck turbo's, ever stop to think how hard a truck's turbo works??
holset, kkk, ect all good turbo's.. (ANY chinese manufactured turbo is crap, i dont care what anybody says)
the MAIN reason people use garret is because they have so many frame, blade, ect. options and because spares are easily avaidable, not just because they are the best turbo's out there
i must say, i dont mind what the turbo comes of, its beens tested and found to be reliable, and makes good power, so what it comes of is the least of my concern really
my opinion
... niether do i, but i doubt a truck turbo will have BB responsiveness though.. and thats a big factor
turbo's are like the story "animal farm", any turbo will work but other will work better.
The big thing about Garrett turbos are the ball bearing center and being water and oil cooled.
The ball bearing versus the journal bearing difference is huge! You really cant compare the two! For one the responsiveness of the ball bearing is ten times better than your journal. In other words you can go much larger turbo with garrett and recieve allot let turbo lag! Thats a huge bonus! GT28RS turbo is larger than a stock T28 turbo, however the gt28RS will be spooling allot quicker...ballbearing versus the journal bearing.
Reliability also comes into play! garrett ball bearing turbos can handle huge amounts of boost non stop! And Im talking about boost here...2bar plus!
Journal bearing cant take that type of punishment! They just wont last as long on high boost applications. Fitting a turbo and be able to make good power is the easy part....getting it to make power reliable is a whole different story!
I spent R50k on a plain motor swop....not making huge power but making it reliable 200kw on the wheels everyday.
Im not saying other turbos are crap. Go for what suits your pocket. If you go for the "truck" turbos dont go for a high boost application, keep to 1 bar boost. Also expect to have allot of lag if you go for a large turbo, otherwise stick to a smaller turbo with less lag....
In the long run I just think saving up and bying a proper Garrett will save you money on turbo rebuilds.
I didnt have the money for a garret so I stuck with the stock turbo untill I could afford it....unfortunatly the car was sold before then! 😂

im sorry, that simply is not true.. example, garrett plain journal turbo's fitted to bmw diesel turbo's typicaly run 22psi day in day out..
there is no denying the responsiveness of a ballbearing turbo though.. i agree, go with what suits your pocket, but do remember you get what you pay for.. a cheap knockoff turbo is going to last exactly as long as you think it will 😉

Come on....22psi = 1.5bar boost. As it stated...2bar plus boost is the issue at hand. Show me a journal bearing turbo that will boost 2bar and up just as reliable as a ball bearing turbo? You wont find one.
Thats why I said, play it safe and boost a journal bearing turbo 1 bar to ensure it lasts. You can boost it more however that will shorten the lifespan of the turbo by allot.
Also BMW turbo or modern world turbos (especially diesel turbos you cant compare to the truck turbos we are talking about. Tecnology with these turbos are past what we are discussing).

haha good reference 😂
i must admit that i dont have the hard evidence to back this up, but some rebuilt journal bearing holsets that i have been researching apperently can run over 2bar boost, ive read this on a couple sites, but since no one here has tested them who knows...
it also depends on what application u looking at, im building a dailly driver so im not gona be driving on 2bar boost all day
not saying that i will be getting a holset and only looking at a turbo upgrade after my motor swop, but the holsets are cheap, reliable, and can make good power, and depending on size ive heard that the smaller ones spool relatively well and quikly.
at the end of the day i think i would rather chance a holset and if it f*cks out buy another or even ANOTHER again, and it would still work out cheaper then a garret
(but if i had an endless budget i would go garret 😛 )
