Hybrid still king?

[John B]

A couple or so years back, conventional wisdom regarded the T4/T3 S50/.63 stg. 2 hybrid as about ideal for a good breathing 2.5 8V engine. Does this still hold, or have newer turbos put the hybrid on the "flog on Ebay" shelf?

[Juggy]

id take my GT3076R over a t3/t4 journal bearing anyday....

it just really comes down to your HP goals, if your looking for a good street setup or track setup, or soemthin in between....yada yada....and of course, PRICE.

i think its funny how everyone jumps ship. most people are afraid to try new things but when they find out what works they are quick to go and copy....

[John B]

By the time I figure out what to copy, it changes.

i'd personally go DBB over a journal bearing t3/T4...and holsets also have a become a very good alternative for those on a budget!

but like juggy mentioned, a lot of variables come into play when choosing the right turbo

I thought u had a S50 t3/t4 judging by your sig??? i can spool my bigger turbo just as quick or faster (in some cases that i read about some setups)

DBB FTW!!!
they spiiin sooooooo nice tooo. they are a much better choice for a street/auto x cars as well. as they spool approx 500rpm faster then a same turbo but in non ball bearing config...
not to mention the reliability....

if you went with a DBB turbo, id honest suggest the "disco potato" its the GT28RS its pretty much an improved S60 turbo, but will spool better and make more top end (have been pushed to 350whp) which im pretty sure the approx range your looking for? its seriously overlooked by turbo mopar'ers. id love too see someone use that turbo on a 8 valve setup....

Just for the hell of it I typed GT28RS into google and came up with a vendor selling it, 1100 bucks!!! ouch! no wonder people dont go that route lol

Spool and turbo response is 90% dependant on tune and properly set-up supporting mods, 10% turbo config. You can spool a journal turbo just fine IF you set things up right.

[John B]

Yes I have the S50/STG2 hybrid. I just notice that no one discusses them anymore; it's all GT this, GT that, Holset, etc.

It's also funny how some make that dated 50 trim outperform much better turbos..... (mostly due to the setup and tune)

Look at Pat's #s in his GRM Shadow (high tens on just boost) Mathwise... he's probably pushing it around 470whp... which is supposed to be done at 380-410whp.

My opinion: if your goal is 350whp, then a 50 trim would be a great choice.

edit: (even though you could find a more better suited turbo combo that is exotic I'm sure, for more $... Ondonti would be able to chime in on that topic)

I still love my S50 hybrid. Still a great bang-for-the-buck turbo for 400hp.

That said, if I had to replace it, I would shop some of the newer-tech turbos. I don't know much about the Precision or BW turbos myself, but friends and fellow racers rave about them.

Somebody recomended the Disco Potato... that is a pretty specific turbocharger... GT2860RS if memory serves. That has proved to be a great turbo for 2.0L DOHC engines that breathe really well, namely the Nissan SR20 family that want ~300hp, and don't run a lot of boost to get there. Like under 20psi. I don't know for sure, but I don't think it would be a good turbo for our 8v applications that need to really have the air SHOVED into the intake port to make big power. The GT2871 might be a better combo.

[Vigo]

Im putting a gt2871 comnpressor side on my vnt. I guess we'll see how that pans out. Ideally one would want a higher-flowing turbine side to go with it, though.

You get what you pay for, a decent hybrid is $800, so is it really that much difference?

I love the DBB's, but I also never got to try the HE351, so I can't compare back to back but the GT35R is totally different animal than my old 50 trim Stage III.

John, what are you goals? The new crop of turbo's are unreal but also the 50 trim does the job well.

Proven performer, not much more to talk about.......

[unluckyty]

I think it is dependant on specified use of your car. I have run T3/T4. 63- 50 trims stage II on a couple cars ( all 2.2's and 5 speeds), and is what I like, for an upgraded turbo.

My cars are street driven with drag strip fun. The slightly slower spool up helps with street tires and has an impressive top end, but put a set of slick on and leave at 5k and your still good for a track day.

One of the biggest advantages of the DBB turbos is reliability. Lose oil pressure for a fraction of a second and you can kiss your journal bearing turbo "good-bye". DBB turbos can survive sans oil long enough to get through those long sweeping turns where oil is pinned up against the side of the pan and not around the P/U tube.

I've got that jim-dandy deep sump pan with windage tray and trap doors you made for me, so no problem on the sweeping turns...I hope

Good point Chris on the DBB being good for cornering, and Simon you are right for 300 bucks more really isnt that much and to think that it would be a better designed turbo. All very good points, Wish I had the money to go DBB, 500 less rpms, yes please!

Of course I say that buying a used GT35R, lol.

But if I had to, I probably would go DBB again, it really is nice,

Cheap Holsets ftw!

[OmniLuvr]

Cheap Holsets ftw!

yup, and the hy35 is very similar to a T04E 50 trim, i believe you can put the better flowing he341/351 turbine housing on it and have a 4" dp
