Let's keep it that way.Im amazed this thread has not developed into an arguement yet
you mean will they last longer? not really should be about the same life as a stock ct9.
if so its debateable. depends on the quality of parts used and how well it was balanced. most will use standard bearings too. in theory though if a turbo is well built, balance and is well looked after it shouldnt fail at all. regular oil changes, good engine breather sytem, warm up and cool down ect. ive striped down many 12 year old ct9 and the bearings are like new inside after all this time with no wearing at all.
if you think about it though when people buy hybrids they run them at higher boost and close to there limits. so thats maybe a reason they will not last so long.

The difference is spool/lag is minimal, hardly noticeable especially with the hybrids using a modified stock size compressor housing

Off topic mate, this is about CT9 hybrids, best to start a new thread
@timmy, the Tongs-turbo's also look new. Don't know if they really are new or...
I believe that the compressor housing of the GT-spec comes from a Toyota diesel that has another kind of outlet. That's why it shows the "weld".
@Turbodave, Chanced the post and did some research.
Some info I gathered:
The CT9 is a journal- bearing turbo and it uses a 270-degree thrust-bearing washer (at left). The 360 degree washer is on the right. It provides better oil disperse.
Little side note: The journal bearing is the bearing that support the shaft and allow it to spin. The thrust bearing is what takes the side loads of the shaft. A thrust bearing has no impact to spool time.
Second part from the right is the journal bearing.
@Turbodave & keirz about the the larger waste gate flap. How could you say it's not needed? Ok, it's not needed on the standard CT9. But the turbo could simply be "hybridized" so much that the maximum size you can get with the standard flap just doesn't cut it anymore. I believe there are 2 options in that case, enlarge the waste gate flap or go with an external waste gate.
Anyway, I hope the traders that sell these turbo's can get us some more info.
For example:
Dave: Can you get us more/any specs of your hybrid?
Toby: Do you got a photo of the intake side?
Enzo / Tongs-turbo's: Are the turbo's new casts or refurbished units?
Sam: What kind of trust bearing washer does your turbo use? Can you vouch for the quality of your castings to be as good or better then the genuine stuff?

If you are not suffering with creep i.e. the wastegate is large enough and cut on the optimum angle for the release of the exhaust gasses then there is no need to weaken the turbine housings wastegate by un-necessary porting and the addition of a larger flap.
Cut back turbine blades will increase creep as it will allow the exhaust gasses to escape the housing quicker and spin the turbine wheel faster at higher RPM.
I know the difference between 360 and 270 degree bearings and i know that Tobys turbos use the 360 degree bearing setup.
I dont think I can read anymore of your posts you clearly havent got a clue what you are talking about when it comes to turbos.

good info lads i would like to point out one small thing.. from all the above mentioned turbos not one of them is a hybrid.. they are all in fact HIFLOW not hybrid turbos..
a hybrid turbos is 2 completely differnt turbos mated together.. say for example a ct9 with a ct20 compressor housing
if the housings remain the same yet they have bigger intake trumpets & uprated internals they are known as hiflow turbos.
just my little input

If it has modified internals than the phrase Hybrid is good enough for me. Perhaps it is different over with you though?

hybrid is right. hybrid by definition means its made from two different things to create a new thing (very simply)
Not being picky but how come compressor and turbine housings class as different "things" to create a hybrid but different turbine and compressor wheels dont? Why some partsand not other parts?
TBH its a load of tosh to me, hybrid, hi-flow its all the same, a turbo which has been modified using different parts to create a better overall turbo.
this seems to be getting out of hand with some people i did choose to go with dave burwsh hybrid purely for the warrenty and have dely with him before and have always been very happy with the way he does bussiness great man to deal with even if there is a problem with anything he puts it right straight away
but lets all face facts the only way to solve this debate is to have all hybrids to gether with identical set ups and put them to the test but lets face it even after that some may argue about tollerance of different engines ect PERSONALY I DONT THINK PERFORMANCE WISE THERE WOULD BE MUCH IN IT AT ALL.
and one massive point i would like to make out its all right makeing your opinions on calling the turbos dave burwash and toy tuning ect but do many of you acctally no the companys that do the work to the turbos there lies the key to the best reccomended company in my eyes
thats my 10p worth lol:homer:

agreed, any turbo that has had its internalls 'enhanced' from its standard form, to increase performance, to me is a hybrid unit.
to add to the discussion i have no experiance with any of the mentioned hybrids, although i do no who makes Dave b's turbos as they hybridised my k24 and they are a very very good company.

well ive got a toy tuning one and im on my 2nd turbo
the first one went due to sand getting in some how
now on my 2nd one and it seems to be fine
when i changed it from standard to hybrid i noticed a difference

In that case the one I got from Ganni was the best, although I know feck all about it.

when the compressor housings remain the same & u uprate the internals the turbo itself remains the same exteriorly, so its known as a hiflow turbo as uv increased the flow of the turbo by increasing turbine & compressor wheels.. thus it has a higher flow capability hence the name hiflow turbo..
now a hybrid is a hybrid coz ur actually changing the compressor or turbine housings.. thus increasing the flow by doing exterior modifications as well, ie by changing housings as well as internals.. hence the name hybrid.. ie 2 different units mated together to create a new turbo
