TD05H, is this a 16g big turbo!

[Talontid21]

Is my TD05H a 16g big turbr is it just a TD05H stock turbo.whats the difference?

 

[Eliminat0r]

turbine housing is how you tell the difference

Also look at the compressor wheel. 14b = single vains 16g= double.

WHat other ways to check?

That's pretty much it. You have to look at the compressor blades.

This is a 16G.

Here's the best comparison I could find of the compressor blades with a shot of the 14B. The 14B has flat blades, 16G has stepped, as stated earlier.

It looks like the 16G and 14B have the same size compressor housing. Is the interior of the 16G compressor housing larger in diameter than the inside of the 14B compressor housing?

Thanks for the pics. A little turbo 101 please...so the 2vain fins have better flow than the single vain? But the single vain has more fins.

14b, s16g, and b16g share the same compressor housing. The only way you are gonna tell the difference between a s16g and a b16g is to take the compressor housing apart and measure the compressor exducer diameter. Here's the specs:

No. They are both TD05H compressor housings, exactly the same internally. The only difference being the size of the compressor wheel - the small 16G is larger than the 14B, the big 16G is larger than the small 16G, etc.

It looks like the 16G only has 6 fins, but actually, they both have 12 fins. It's just that some are smaller and some are larger on the G-series Mitsubishi turbos (13G, 16G, 20G, etc).

Also, most 16G's are equipped with Mitsubishi 7cm2 turbine housings, while stock 14B's have 6cm2 housings. This allows more exhaust flow (and therefore is less restrictive as far as top-end power), at the expense of a little more turbo lag.

The 16g housing has to be machined inside because the wheel is a little bit bigger.

Interesting! You know, I actually wondered about that after maybe 10 minutes after I posted that. Thanks for the info and clearing that up.

the 16G has a larger turbine wheel to accompany the larger turbine housing, compared to the 14b turbine wheel.. correct? or are they the same turbine wheel?

 

[psychlow]

I BELIEVE they are the same turbine wheels. Can anyone verify this?

 

[seth98es]

Yup, on the turbine housing there will be a 060 or 070(6cm2 and 7cm2), pretty sure all big 16gs are 7cm2 like mine
