Default Hybrid Turbo

Does anybody heard about hybrid turbo???

I mean, put an hot section of a turbo "X" and the cold section of a turbo "Y" together.

I heard about a mix of a cold section of a VF23 and the hot section of a VF39 and I look to get some information about it. It seems to get some good reasult in therory (low end torque and high end hp with a ball bearing turbo)


So, can anybody get some info about it???

PS: I'm french canadian, so I'm sorry for my english, I will do my best

Just get the VF34, It's an awesome balance between all the "VF" turbos. I personally have it on my 03 bugeye and put down 340whp on 21psi. I wouldn't go "hybrid". Get the 34 and you'll be pleased with the response and power. Good luck!

Not on a 2.0L, sorry.

I've personally never heard of anyone making hybrids out of any VFxx's before. You might get better responses in the Proven Power Bragging forum.

Hum, yes I know about some of the VFxx that already be hybrid like the VF23. I also heard about the good result of that VF34.

My goal is to achive low end torque as much as possible. I actually have a 2.5L WRX with the TD04 and get 263hp and 290lb-tq on the Lachute Performance dyno (on motor).

I would like to get a good all around turbo that can break the 300 on each measure.
I like things that are not OEM and out of the box. I also like to do something first, that's why I look for hybrid turbo

Try a new combinaison of cold and hot housing of turbo.

What correction factor, and what kind of dyno? My 2.0 liter put down 350whp/350wtq on an 18g on e-85 at 22 psi. So I dont believe your numbers for a minute. My numbers were on a 1.15 CF on a dyno dynamics dyno

Can you please debate on his numbers on PM or elsewhere.

It is not against you and I don't know if you are good or not, but it may held to a long debate not related to this posts and this will not help my search.

Thanks,

I wouldn't consider that a hybrid because thats what makes them what they are. (if that makes sense?)

A VF39 with a 20G wheel would be a hybrid.

The VF23 is the cold section of the VF22 and the same hot section as the VF24.
I know that is an hybrid, but it is also an "official" VF.
That it is not what I search.


In other words, can we use any hot section with any cold section of any VF serie turbo???

You can swap the various turbine housings between some of the VF turbos.

For example you can put a p18 housing on a vf22 for better spool if you wanted.

Some exhaust housings will not fit or will need to be machined to do so.

VF23 and 24 share the same compressor. The 23 has a p20 exhaust housing the vf24 a p18 housing. It doesn't make them a hybrid as thats what manufactors do.

"I heard about a mix of a cold section of a VF23 and the hot section of a VF39 and I look to get some information about it. It seems to get some good reasult in therory (low end torque and high end hp with a ball bearing turbo)"

IMO the difference would be small and not worth doing.

I think you would need to machine the vf39 exh housing to fit a vf23. The p18 from a vf34 will swap straight onto a vf23.

All that would achieve is a vf24 which IHI already make !

A vf34 is a better turbo than a vf23 or 24.
