I have a 2004 cavalier,
Hahn Stage 2
I "think" I may be reaching the limits of my 16G How do I tell? How far have these been pushed?
Contacted HRC, seems ever since the old man left town things are a little wired there... i.e. slow...
They quoted me $550 to do the conversion...
My question, is this even worth my while? Could a different turbo suit me better?
Is there a less expensive route I could take?
The 16G is good to about 350 horsepower on the Ecotec. Not much more after that, it starts to lose efficiency. The 20G will go in excess of 500 horsepower.
Currently #4 in Ecotec Forced Induction horsepower ratings. 505.8 WHP 414WTQ!!!
Currently 3rd quickest Ecotec on the .org - 10.949 @ 131.50 MPH!!!
will you hurry up and do your wierd ass conversion so I can tell if it works?
Haha, it'll be a couple weeks at most!!! Patience, young grasshopper.

paitence I have...
Please PM me with the results
The 16g and 20g are similar but still very different.
I am running a MHI (mitsubishi heavy industries) Big 16g on my setup, not a hahn kit.
If I were you, i would find out the exact model of your 16g and look into the DSM FP Sleeper 16G Turbocharger.
Its $1170 dollars but I believe you do not have to change anything at all what-so-ever.
That will be my new turbo once I max mine out.
Here is their website. They are a very reputable company, not an ebay know off seller.
Forced Performance
I think $1170 is kinda steep...
For $550 I can convert my 16G to a 20G that will flow enough "according to Hahn" for 500hp
I would really like to know how your going to "convert" your 16g to a 20g?
The impellers will not fit correctly in the opposite corresponding housings.
And if you use the 20g housings you will need to re-do your charge piping and downpipe.

47 year "old man" here...man you guys are hilariously pessimistic about getting older!I Dunno, you sure don't have a lot to look forward to if you think you're going to be "old " in your 40's. I sure ain't! Cheer up. It gets better, not worse
As for our current inquiry response time: you'll have to deal with the effects of the economy and our ongoing move if you want us to take care of you on that turbo. We just don't have the staff currently to treat every inquiry as if our lives depended on it. They don't, and our customers who appreciate quality don't seem to mind a bit.
I think what you'll get for $550 is the most value of anything you could do. It will be a freshly remanufactured Super 20G that has gone low 11's @ 125 in a J-body, and can make 500 HP...and will bolt into your existing system perfectly. If you can beat that, you have my admiration. I don't think you can!
Now if we could just work on your impatience and ageism, lol!
KIDDING. Take a joke, fellas. Jeeze!

Here's how he does it: He puts it in a box, seals it, ships it to us, then re-installs it when we ship it back converted to Super 20G specs. Yep, it's just that easy
What we'll do is disassemble, inspect, machine, rebuild, and reassemble the unit with a Super 20G compressor section (wheel and housing). The 10cm2 TD05H turbine section is retained.
No piping or downpipe will need to be changed. It's a direct bolt-in on a Hahn turbosystem.

So you machine the 20g turbines?
Because from what I know, they do not just drop into the 16g housing!?
You may not be completely aware of what the term "20G" entails. It is a compressor section, not a turbine section.
Our Super 20G turbocharger (a Hahn RaceCraft exclusive) carries the designation TDO620G/TDO5H-10CM2. It is a hybrid, not unlike a Garret T3/T4. The designation braks down like this:
TDO6 is the compressor family.
20G is the specific compressor.
TDO5 is the turbine family.
H is the wheel series.
10CM2 is the A/R ratio of the turbine housing.
Let me know if you have any other questions. As the largest turbosystem distributor of Mitsubishi turbochargers in North America, we have considerable expertise at our customers' disposal.

Well in that case, i just might have to talk to you in the future about that.
Do you have a compressor map for it, or is it the exact as the TD06 map?
Does 550 include a rebulid too, seals, thrust bearings ..... ect?
Or just the compressor swap out and balancing?
BTW did you see the intercooler I ended up making, the same side enter exit one, we were discussing a while back?

I presume you mean the same as the TD06-20G compressor map, and yes, it is the same (there are many TD06 compressors, 20G is the one we use).

Yep. For longevity, we always rebuld with new internals when we upgrade. The turbo will be in like-new condition.

No. I did not. Sounds fun, got a link?
