Maybe this one?

It has a 60-1 compressor wheel.
But it has an 8 CM turbine housing.
This turbo should hit boost really fast & hard,,, but will be restricted by the stock sized 8 CM housing.
Here is a 20G w/a 8 CM housing. It also has the standard TD06 turbine wheel which IMO is too small to begin with.

I had run a 10 cm housing w/my 20G turbo, & I would think there is not much difference in performance from a 8 CM housing. The 10 CM housing was pretty restrictive IMO. The 12 CM I had machined to fit the larger 20G turbine wheel seemed to have more of a mid end to top end power increase,,, but not by much. A little looser converter I would recommend about 2400 when running a 12 cm housing. I am using a stock converter & am getting by with it, but I know my Sy would most likely drop 2-3 tenths in the 1/4 mile w/a better converter. That would put me in the 11.70-11.80 range w/my stock engine. I can only hope.:roll:
My current turbo is a 60-1 compressor wheel, 20G (H) wheel & a 12 CM turbine housing.

Re: Where to buy a 20g10cm turbo
I have no first hand experience, Mike tried one, he said the turbine wheel was too thick so it would not spool up & make boost. Forgot what the actual specs were on his turbo? Mike ?
Problem w/Mitsubishi turbos, they do not offer any good upgrades, a 20 G is a poor upgrade w/a 14 CM turbine housing & running a stock converter IMO.
For the price & offering different sized turbos for our Sy/Ty's I would try them out if I could not have machined my own parts I needed to make my current combo.
They have a 99% feedback of 16989 transactions. If I bought a crappy turbo from them I would definitely give them bad feed back.

Re: Where to buy a 20g10cm turbo
Problem is, I believe the PTE turbo smallest A/R for the Sy/Ty turbine housing is .85?
If they made a smaller A/R, like a .63 or so, I think that would work better for a stock torque converter.

Re: Where to buy a 20g10cm turbo
Lets see a video of how fast your 20H turbo spools w/a 14 CM housing & a stock converter.
What you say of no problem spooling your 20G could be a laggy slow spooling turbo to another.
0 psi @ 2100 RPM, are you kidding? 10 PSI by 2800, horrible IMO.
When my 20G was standard but w/a 12 CM housing it would get 2-3 psi in neutral by 4800 RPM
My current 12 CM housing can grab boost 5-6 psi by 4500 in neutral
When I used a standard 20G turbo ,but w/a 12 cm housing by 2100 I would see 20 PSI +
Like I said, it's all in the eye of the beholder.
So in my eyes, 0 psi @ 2100 is a major problem.:2cents:

Re: Where to buy a 20g10cm turbo
You have posted a few times about having a stock TC but yet it stalls to 2800 rpm. I dont remember but i dont think i ever saw more than about 2300 rpm with my stock TC, and that was building 10-15# boost on the brake with the stock turbo.
Are you sure you have a stock TC? Just asking, because 2800rpm seems really high.

Re: Where to buy a 20g10cm turbo
I could see the brake is on & TPS %, I find it hard to believe your 20G spools as fast as your stock turbo, unless you had problems w/your stock turbo?
I do the same , hold the brakes, give a little throttle & watch the boost come in. I do not need to floor it by any means, not even close.
What times do you run w/your 20G? 60 ft 0-60 MPH 1/8 , 1/4 mile?
What times did you run w/your stock turbo as a comparison?
You are the only one on this board that says your 20G turbo spools as fast a stock turbo.
Is everyone else wrong saying bolting on a 20G turbo w/a 14 cm turbine housing onto a stock torque converter Sy/Ty (regardless of what wastegate actuator is installed,) causes the boost to come in slower?
The only way I see your 20G turbo spools as fast as a stocker is because you are hitting the nitrous button, or you have one of these turbos w/a 8 CM turbine housing , http://www.ebay.com/itm/Kinugawa-GM...Parts_Accessories&hash=item232b706194&vxp=mtr (BTW, not really a true 20G turbo)
, or you machined a 8 CM turbine housing to fit your 20G turbo. Or even a 10 CM turbine housing will spool quickly.
BTW, having L35 heads & a 20G turbo is not a good comparison, as to stock heads & a 20G turbo.
I also have a stock TC & have brake boosted to 19 psi, no wheel spin & noticed my converter actually brake stalled to 3025 RPM. I watched it many times when I recorded my runs while tuning w/TP5, & I did not believe but the recording proved it.
Normally if I brake boost to 5-8 or so PSi, I see the RPM of 2100.
If your 20G turbo spools as fast as you say it does, good for you, all I am saying is, that's not the norm.:2cents:
Peace!

0966Sy - What is your top end of the engine? I thought I read you had vortecs/L35s. If so, it's hardly a fair comparison.

Code what?
Stock l35 heads, stock cam. I know it's a 14cm housing because its stamped onto it. And yes I'm sure it's a stock TC.
I cruise at 65 on the highway at 2,000rpm. No hard feelings, if your going to upgrade from the stock turbo you have to have at least a 2800 stall convertor. I'm looking into a 4200 so I can get out of the whole really fast. Should shave seconds off my ET
