TD05 20G vs Garrett Equivalent

[VIN18M]

Anyone know what the 20G is comparative to in the Garrett range of turbos?

I know most of the Garrett turbos around this size are ball bearing so spool time is slightly better, but in regards to size/hp output what would be similar?

 

[EV0300]

Gt3071 I would say

 

[VIN18M]

Really? That big??

 

[evopwr]

I always thought td0520g was just a 'small' upgrade from the standard e2-3 td0516g. Whereas the td0620g was more like a gt30?

Really need to compare turbo maps.

I would have guessed a gt25 or something.

The garrett turbo app is pretty good. All the maps.
For post code in the app I use 90210 as its the only us postcode I know off by heart.

Na beverly hills 90210 reruns on now.
Oh valerie is still hot.

 

[VIN18M]

Hah 90210, love it!

I thought the 20g was more around the gt28r size?

 

[EV0300]

Td05 is bigger than a t28 so ibfigure the next one up is gt30

 

[EVOCPE]

TD05H 20G
Compressor Wheel = 52.8/68mm (Inducer/Exducer)
Turbine Wheel = 49.2/56mm (Inducer/Exducer)

GT3071R
Compressor Wheel = 53.1/71mm (Inducer/Exducer)
Turbine Wheel = 56.5mm



Pretty sure the standard TD05H has a .56 AR

So they are quite close I size then?

No, I ignored it.

this is interesting i'll be following this. because ill be throwing on a gt30 on the jummy. but not knowing too much about it but i though it was bigger then the 05-20g's

 

[evo-gsr]

No, I ignored it.

dont be like that now...

 

[DOUGMO]

the much bigger turbine wheel makes a huge difference to top end, it wont choke up top as much.

 

[VIN18M]

So the 20g just has some minor porting and larger wheels and it brings the output up around what a GT3071 would produce?

Because the physical size of them is quite significant from what I've seen online.

Thats because mitsubishi made a good turbo , look at a ct26 of a toyota they are huge but are crap compared to tdo05

^^ True that.
