The Turbonetics kit uses a Stage 5 turbine with is a T3. The exhaust housing is also a T3. You can clearly see it because its tangential with a 4 bolt pattern for the downpipe. T4 exhaust housings only come with a Vband on the tangential housings. To get 4 bolt on a T4, you have to run an on center housing.

If you don't believe me, look at the parts list for the kit. It uses a 30263 gasket, which is a T3 turbine inlet gasket.

 

Thats interesting....read this:

Furthermore here is a picture of a 4 bolt T4 exhaust flange form their page:


Now given all of that and the fact that I'm pretty damn sure I asked and they told me it was a T4 I think its a T4 turbine bro...

 

Is that guy for real MIA

Considering all this time and all the threads on here along with the other Z sites, I can't believe someone would "question" such a thing now


Also projectsherv congrats on being in the 400 WHP club, though I think the quicker the better on getting those bigger injectors and a tune

 

Shervin that's awesome bro. Can't wait to see the car this weekend. Maybe we can get out for a quick Turbonetics group drive after everyone leaves! You'll just have to wait up for me!

My car goes to CPRacing next weekend for AAM Fuel System, Injectors, Emanage Ultimate, Blitz Boost controller and Sharif's magic-touch. I won't catch up with you for sure, but I'm really excited about the outcome anyway.

 

Well think of it this way, at his current set-up I would be hesitent to push her... Well you will be in much better position regarless of your motor not being built for higher boost IMO... Chances are you will not need it, let say you are low 400's coming out of CPR/Sharif like me (also from a brief talk with Sharif, we could have gone farther up in the boost but I had said closest to 400 WHP so if you feel comfortable enough Sharif could tune for 10-11 PSI which could put you above the 430WHP mark)... 20 something more HP really isn't going to be something to serious to consider between you and him... Drivers race I say

 

Give Turbonetics a call and see what they say. When I called, they said it was a T3/T4. T3 Turbine, T4 compressor.

 

MIA, talks to the Vice President regularly... He was a vital part of the kit major production and distribution.

 

I agree, the last thing you want after getting your 350Z back, is to have it mess up again (I would hate to see a forged blown motor).

Just a recommendation to reconsider the tune you are currently on and tune it down until you can get those parts.

 

Not trying to participate in an argument, but i'm just trying to make sure any potential customers are not misinformed.

Turbonetics clearly states that they use a Turbonetics T60-1 on the ST kit for the 350Z. Here is the information on the 60-1 on another link from Turbonetics...

"The 60-1 Performance Turbocharger
Representing the careful marriage of a unique high flow/high efficiency compressor section teamed up with a T4 turbine section the 60-1 has proven itself in every competitive motorsport application from drag racing to bonneville. Available with either the standard (4” inlet, 2.5” discharge) compressor housing or the 60-1 HI-FI ( 2 3/4” inlet, 2” discharge) compressor housing, the 60-1 will outflow any standard T04B with ease! (The 60-1 HI-FI will deliver approximately 90-95% of the flow capacity of the standard 60-1.)"

 

I will most certainly do so tomorrow morning. I assure you that whoever you spoke to must not have been thinking of this turbo. Turbonetics cleary states right here http://www.turboneticsinc.com/ts_overview.htm that it is a 60-1 which is most certainly NOT a T04 compressor. I looked it over again tonight and talked to two seperate shops that have installed them as well as had a buddy who has been playing with and designing turbo kits for years confirm that it is a T4 turbine. I can tell you for a fact that the compressor housing is bigger then a T4 and the turbine housing is damn near the same size. I even pulled my heat shield off and looked at it. Both shops said it was a T4 turbine flange on the feed pipe. And furthermore they all said it was an on center turbo design. But just for grins I will contact Brad and Reggie tomorrow.

 

Sherv, I spoke with your tuner the other day, and it sounds like he has mad skills. He will love tuning with the return system

 

Sherv what shop did your motor build? Are they the same people dyno tuning the car? I really look forward to seeing what you rcar can do properly set-up. When do you get full boost?

 

Ok, as for the shop I used to build the motor I went through Ultimate Performance for my motor build as well as my tuning. Excellent shop with 100% top quality service. As for upping the boost, I have decided to go all out and buy the new injectors and fuel return system(shopping around for best deal at the moment). So you can look forward to seeing some updates within the next week or two. As for video footage ill get some footage of my car, but it wont be any hard driving now that I know the risk involed with the setup im running.

 

For those interested, I called Turbonetics again and confirmed that it is a T3 turbine and exhaust housing.

 

Actually it is a T3 wheel design although the exdcuer diameter is actually larger then a T4 exducer... so from what Turbonetics says its exducer is actually larger then that of a T04 and its major diameter is about 2/1000 smaller. The housing is actually damn near the same size. In other words its a 2/1000 smaller then a T04 but for arguments sake yes its a T3

Edit: There would be zero improvment in flow by going to just a T04 turbine and leaving the 60-1 compressor. Turbonetics suggests going to a larger compressor and maintaining a Stage V

 

The nice thing about a T4 turbine housing is the much larger inlet. If you've ever compared a T3 inlet to a T4, you can see the difference. For guys with built motors, they could benefit by going to a T4 housing with a P trim and a larger compressor wheel. That was the whole purpose of my post originally since the starter of this thread has a built motor.

The T3 wheel in the 350Z kit is a great fit for the car. Keep in mind tho that the size of the wheel is not the key indicator of flow. The shape and number of blades are of huge importance.

I'm looking forward to seeing somone expand this kit with say a 62-1 with a P or Q trim exhaust on a built motor. They should be able to make 600rwhp easily.

 

Dyno sheet yet?

 

That is true...however the Stage V housing is only 1/10s of an inch smaller then the T04 it the Z kit uses a .73 A/R..when I asked them what the benefit would be of going to a P trim wheel maintaining the 60-1 compressor and the said that there would not be any unless the compressor was also upgraded. They did say however that the 60-1 w/ stage V wheel would flow for 500 HP as is with a built motor and that going with a T61 and a P trim would give you the air for up to 600 if need be. A 62-1 would not flow enough to get you much past the 60-1 according to the kit designer...

Edit: They are doing a Stage II kit with this in mind and are going to be using either a T61 or T66 with it...

 

Will the stage II kit with the T61 or T66 install in the same spot? Also I just purchsed a TN single turbo from Avalon and I am also going with a built short block later this year. Will I be able to just upgrade the turbo from my original kit? Thanks.

 

Yes it will...and yes that is the plan...if a T4 turbine ends up being used Turbonetics would include the piping necessary to make it work...although it is still on the drawing board and no actual work is going to begin until after SEMA it has already been set that theStage II will have the turbo in the same location and it has been measured and will fit.
