Re: differences between the greddy 20G and t3/t04e? (redteg1)
Hey redteg1,
Hopefully GReddy and Mitsubishi "20G" turbos are the same... if not, excuse the following.
If so...
Here are a few answers to some of your questions.
I guess for more complete answers, you'd need to be more specific on exactly which compressor/turbine wheels you're comparing. I'll compare mine from a Drag 3 GS-R kit (which uses a T3 stage 3 turbine and a T04E "54" trim compressor wheel) to a few different combos of DSM turbos.
Here is some info I found a while back:
My T3 stage 3 turbine is slightly larger than a TDO6-8CM2 and slightly smaller than a TDO6H10CM2 turbine. Here are the specs:
TDO6-8CM2 = Turbine Exducer / Major Diameter: 2.175" / 2.560"
T3 stage 3 = Turbine Exducer / Major Diameter: 2.229" / 2.559"
TDO6H10CM2 = Turbine Exducer / Major Diameter: 2.315" / 2.650"
and my T04E "54"trim compressor wheel is larger than a 20G compressor wheel. Specs are below:
T04E "54" Compressor Inducer/ Major Diameter: 2.170" / 2.950
compared to the TDO6H20G whose specs are:
Compressor Inducer / Major Diameter: 2.075" / 2.675"
**Model: TDO6H20G-TDO6H10CM2 **
Boost Range: 10-35 PSI
HP Range: 400-550
Max. CFM: 720
**Model: TDO6H20G-TDO6-8CM2**
Boost Range: 10-30 PSI
HP Range: 300-500
Max. CFM: 680
The DSM Super 20G-H is the second step in the Super 20G series. It utilizes a TD06 turbine section to allow higher overall exhaust flow than the standard Super 20G. This larger turbine section makes the Super 20G-H a good choice for cars that are being prepared primarily for high RPM use, such as drag racing. The larger turbine section allows more HP per PSI of boost by reducing exhaust backpressure and therefore improving the delta pressure ratio (intake vs. exhaust). While this turbo is streetable on highly modified cars, one must keep in mind that it will not develop full boost pressure until approx. 4500 RPM.
