If I'm not wrong, the 3065 turbo is a hybrid, consisting of a 35R coldside and a 30R hotside. So, anyway, my question is: are there any versions of the 3065 available from the usual suppliers, that are cofigured with a twin-scroll turbine housing? Anyone running a T.S. 3065 out there?

EDIT: I am especially wondering if there are any 3065's out there with the .78 T.S. exhaust housing on a 2 liter motor. I'd think that this would have fairly decent spoolup.

 

The FP3065 uses a custom-built hotside. The turbine wheel is a GT30, but the actual housing is completely different. Also, your use of the word "hybrid" is incorrect. Hybrid, at least in the DSM/EVO scene, means a turbo that uses a Garrett compressor mated to a Mitsubishi turbine. This allows the turbo to be conveniently bolted to the factory exhaust manifold. To answer your question about twin-scroll, it COULD be done but it would essentially become a different turbo b/c it would end up using a TS GT30 Garrett T3 housing. In summation, what makes the FP3065 a FP3065 is that it uses a custom turbine housing. Otherwise it would just be a GT35R turbo that uses a smaller GT30R turbine wheel/housing.

 

O.K. Thanks for the information. Is the turbine housing of the 3065 a one-off, custom casting, or a machining of an existing Garrett or Mitsu housing. If indeed it is a custom casting, then do you happen to know who produces it?

Yeah, my definition of the term "hybrid" when refering to turbos does not come from a DSM background or any specific DSM/Evo experience. I use the term loosely. And I'm mostly coming from a Buick(Garrett), and Dodge-Cummins(Holsett) background

 

Its not a Garrett option if thats what you mean . We are still nagging Garrett to make twin scroll GT30R and GT35R turbine housings .

 

Yeah, O.K., RSGuy, I finally understood what you're saying...What I'm asking about wouldn't be considered a 3065. It would be a 35R with a TS 30R hotside. Thanks guys.

 

Garrett makes twin scroll 30R housings, you of all people should know this

You can put a 3065 together yourself, you could then strap on a twin scroll 30R housing from ATP and call it a day.

Yeah, I guess that I just might want to add the HTA compressor wheel into the mix as well. So, it would be an HTA comp wheel with a 30R turbine wheel and a T.S. ATP exhaust housing. Maybe it would just implode. But at least I'd have a nice paper weight

 

Forced Performance designed/engineered the turbine housing and builds the turbo. Go to www.forcedperformance.net for more info

 

Sparky, I may have confused you by my use of terminology. In my first reply above, hot-side = turbine housing. I am sorry if I have confused you!

 

RSGuy the fp housing is a lil strange, seems to yield pretty decent results though. I wonder how that housing would effect a 30r.

The FP3052 would be the 3076R in FP's custom turbine housing, if that's what you're asking about. People are running really good times on this turbo. First to come to mind are two local NEDSM members (one with a 1g, the other with a 2g) running very low 11s, and both have the potential to run 10s with it.

The all Garrett version of the 3065 would be a GT3040R. Several vendors sell them. I've also seen it called the GT3082R. Since vendors are making up new names for turbos every other day, just look for the 60mm 84 trim turbine wheel with the 82mm 56 trim compressor wheel combination.

 

kjewer1, yes the FP3052 does use the FP custom turbine housing- but so does the FP3065, which is the turbo in question. I believe the 3065 is the "bigger" turbo, however, as it uses a larger compressor/wheel. You are incorrect when you say that there is a Garrett version of the FP3065. The turbo is custom. It uses a completely different turbine housing than anything made by Garrett. There is no "Garrett version" of the FP3065. Sorry to get off topic for a sec but nice times/trap speeds with your Green setup! How are you liking it?

 

I believe you have misunderstood my post. I understand the turbine housing is custom, obviously, but the rest of the turbo is available from garrett, which is what I assumed was being asked about above. With a regular T3 turbine housing, the equivalent to the 3052 is the 3076, and the equivalent of the 3065 is the GT3040/GT3082. A "3065" in a twin scroll T3 housing would no longer have anything to do with FP. I think with this clarification, if you re-read my post you'll see what I was getting at...

The 3065 is larger, since it runs the 35R compressor wheel (GT3582R). With the 30R turbine wheel though, I always expected that people would run into a restriction before reaching the maximum flow of the compressor wheel, and that does indeed seem to happen somewhere around 600 whp. I always thought it would be badass if FP offered a "3565," to use their terminolgy, but I'm not sure if they do. Actually, this is probably what buschur is using in their cast manifold 35R kits, since it looked like a FP housing last time I looked into it.


This should probably be a PM, but I loved the turbo. To be honest though, there was always something missing. Either in the setup, the tuning, or the driving. After removing it I did find some issues the car had in addition to the extreme thrust play, too late of course.
