Guest jt240z Posted April 30, 2003 Share Posted April 30, 2003 I ordered a turbo with the following specs: Turbine: T3 .63 A/R Stage 3 wheel Compressor: T04E .60 A/R 60 Trim Center section: oil and water cooled What I got was everything but the stage 3 wheel. My question is what impact would having only the standard wheel have on the performance of this turbo? I'm debating on spending the money and getting it modified for the stage 3 wheel but the cost is a little high at around $250 just to add it. I'll need a new wheel and the turbine must be machined to accept it. I got the turbo at a great price so it's not to bad. Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted May 1, 2003 Share Posted May 1, 2003 Why are you not sending it back, and getting a refund? Who built the turbo for you? I would send it back and get a refund or have the builder make it right, or I would trash him on this forum. To answer your question. Without knowing what turbine wheel you have, but assuming it is a stock nissan one, or a small one, the 60 Trim compressor will outflow it by a wide margin, which will cause excessive backpressure, which creates heat, which will transfer into the compressor. You need turbine flow to match that compressor, and it sounds to me like you and your builder need to have a pow wow. Do we need to create a HybridZ mafia to kick someone's A$$?

Guest jt240z Posted May 2, 2003 Share Posted May 2, 2003 Looks like they didn't charge for it, so that's not to bad. Now I'm just deciding on should I go for the standard Stage 3 or the GT 10 Blade? Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted May 2, 2003 Share Posted May 2, 2003 10 blade. Quote Link to comment Share on other sites More sharing options...
yo2001 Posted May 2, 2003 Share Posted May 2, 2003 It's hard to find a turbo shop who has Garrett 10 blades but Turbonetic makes 10 blades also. Quote Link to comment Share on other sites More sharing options...
Guest Zcarsmakemyheadhurt Posted May 2, 2003 Share Posted May 2, 2003 The only real difference between the stage III and a standard T3 shaft is the exducer is a bit larger on the Stage III and it is a clipped wheel. That means it will have a little more exhuast flow and spool is a bit faster. Not that much flow and not that much quicker spool. No big deal, your going to make the power no matter what. Good luck.

That sounds like a contradiction to me. If you have a bigger turbine and clipped blades, you will get more flow, but the spool will be SLOWER.

Guest Zcarsmakemyheadhurt Posted May 2, 2003 Share Posted May 2, 2003 Ooops I am a little wrong the T3 has a 1.916 exducer and 2.320 Major dia. The stage III is 2.227 and 2.55. A difference no doubt and it will flow more but. The shorter clipped wheel has less mass and produces a quicker spool at least I found that when I swaped from a stock T3 to a E with the stage III. You'll be fine with the T3. Quote Link to comment Share on other sites More sharing options...
yo2001 Posted May 2, 2003 Share Posted May 2, 2003 I don't know, I think the 10 balde Garrett suppose to build boost just as fast as 11 blade due to more effiecient design. O Alex, Does T3 super 60 comes with stage III turbine? I was told those are 10 blades Quote Link to comment Share on other sites More sharing options...
Guest Zcarsmakemyheadhurt Posted May 2, 2003 Share Posted May 2, 2003 If you want it built like that it can but nothing comes with a stageIII from factory. Its a upgrade for Grand Nationals. Quote Link to comment Share on other sites More sharing options...
yo2001 Posted May 2, 2003 Share Posted May 2, 2003 Cool, Thanks for the info. I got me a turbo. It's just a T3/TO4B hybrid... with 2.3xx exducer and 3.0xx major trim wheel and Stage III turbine Quote Link to comment Share on other sites More sharing options...
Guest Zcarsmakemyheadhurt Posted May 2, 2003 Share Posted May 2, 2003 Your may not make 450hp that a stage III wheel with a E can produce but if you dont have large injectors and a kick butt fuel computer your not gonna hit that mark anyway. So if your looking for the big power and the money has been spent on the rest of the combo seek the larger turbine shaft. Peace out.

Lockjaw Posted May 2, 2003 Share Posted May 2, 2003 Well I got a 2.7 inducer and a 2.5 exducer. Quote Link to comment Share on other sites More sharing options...
Guest Zcarsmakemyheadhurt Posted May 2, 2003 Share Posted May 2, 2003 Looks like your closer to a stage V wheel. Turbonetics catalog shows a 2.437 exducer and 2.795 Major Diameter for the stage V. Quote Link to comment Share on other sites More sharing options...

Lockjaw Posted May 2, 2003 Share Posted May 2, 2003 Yeah and it is missing a blade too. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted May 4, 2003 Share Posted May 4, 2003 Alex, Would it be detrimental having a T3/T4E with Stage 1 turbine (11 blades) ? Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted May 5, 2003 Share Posted May 5, 2003 I would not want a stage I. That is not going to flow much. I would go stage III minimum. Quote Link to comment Share on other sites More sharing options...
Guest Zcarsmakemyheadhurt Posted May 5, 2003 Share Posted May 5, 2003 If you have your combination fully built with correct injectors and fuel computer to make 400hp+ then I would say up the turbine wheel for sure. If your car has a stock fuel computer and your not going to pass 12 to 15psi I don't think your going to need the upgraded turbine. The big qestion are you going to make the big power the TO4E can produce? Quote Link to comment Share on other sites More sharing options...
