Re: Pistons suggestions for a Turbo Vortec 4.3L

Turbine wheel is way too small.:2cents:

That turbo is made for smaller engines 2.0 liter. yours is 4.3.

My stock engine made 396 HP to the wheels @ 24 psi w/a Hybrid 20G turbo, 12 CM turbine housing & a 60-1 compressor wheel. It is not much, but I am pushing it pretty good.

Ok, but it's what I have. The only TD06-20G I could find when I was shopping was a Kinugawa (whom I may never give my business to again) and another company who wouldn't respond to emails or answer the phone.

That being said, what Compression Ratio does everyone suggest to run with this turbo and front mount intercooler, mechanical boost controller and BOV?

Re: Pistons suggestions for a Turbo Vortec 4.3L

I would shoot for 9-:0- 9:2.1 for compression.

Use methanol injection because with such a restricted exhaust from that small turbine wheel, your EGT's are going to be high.

What dealing's have you had w/Kinugawa? Just curious.
Thx

I bought a stock Syclone turbo that ended up having shaft play and turbine & compressor wheel damage, so I contacted Kinugawa (KAMAK DYNAMICS Co) about parts that I would need to repair and upgrade to a 20G. Bruce from Kinugawa responded quickly (within 1 hr) and I ordered TD06 rebuild kit and the Syclone 20G kit (Compressor wheel, housing and superback insert kit) for $275.55. The items were ordered on 02/22/13 and did not receive it until 03/01/13 from mainland China. Both the rebuild kit and insert kit had the same problem. The ID of the "superback" insert was much bigger then the bushing that was supplied. Also, the stock wastegate actuator wouldn't line up with the holes in the new 20G housing and there was no tube to connect the wastegate actuator tube to.

I took a few pictures, emailed them to Bruce at Kinugawa (same guy I originally got such a quick response from) but did not a response. I tried calling multiple times, but got a "This Magic Jack number has not been assigned" error message. After a week, I tried e-mailing again and got no response. I ended up filing a dispute through PayPal. PayPal never got a response back either, so I had to pay to ship the damn things back to California (address provided by PayPal for the business address on file) with signature request and tracking number. Ended up costing me around $50 to ship the parts back, which I did not get reimbursed for and I did not get my money back until for the reversed transaction until 03/28/13. I have not heard from Kinugawa or Bruce since and will never do business with either of them again.

Thank you for the response, BTW. I looked in the TD06-17c and it has an 8 stamped into the exhaust hausing. So 8cm2. My TD05 is bigger that the stock TD06?

No. 10cm2 is larger than 8cm2 housing but the td05 wheel is smaller td06. The td05 is usually used 4 cylinder motor. Our 4.3's are a relatively large v6.

No luck, even though they are based in Griffith, IN, the woman that answered the phone said "we no have flow map for turbo." in a thick Asian accent.

That seems hard to believe. Is this a common practice with turbo manufacturers?

Yes. The issue is that Mitsubishi is the company that development the part. The manufacturer assembled/machine and mixed matched Mitsubishi's parts. If you call PTE they usually don't have the maps unless Garrett or Turbonetics has released them.

That turbo is way too small. Personally, Id sell yours and get a bigger one.

OK, I'm not opposed to that, but I have not been able to find a TD06-20G with an internal WG and a T3 style flanges (stock replacement). Any suggestions and please don't recommend Kinugawa.

Is this your bush?
Re: Pistons suggestions for a Turbo Vortec 4.3L

I'd roll with kinugawa! Haha kidding I thought our flange is a t4? Correct me if I'm wrong, I found my 20g with a 10cm housing on here , they are like unicorns they are seen every once in a while used unless you wanna go new , then conact Hahn racecraft or roll with a stocker and do the billet wheel from sportmachines.

I would think Kinugawa has better quality & work better than the cheap $ & improper sized turbo you have in your possession . http://www.speedyracer.com/Turbocharger-TD05-DSM-20G?filter_name=TD05

At least Kinugawa has the correct sized turbo for your app. If you are going cheap, you should get the correct sized turbo.:2cents:
I know you had a bad experience before, but maybe they will make up for there bad?


I have not used there products, but Don is going to use there turbine wheel, should be interesting how it works out for him. Go Don go!:tup:

A new real (authentic Mitsubishi) 20G turbo is going to cost you $1000+

T3/T4 are the same on the turbine inlet for what I can tell. I purchased this for the final install, but I have test-fitted it on the stock manifold flange.
http://www.summitracing.com/parts/SCE-9428

I have also talked with Hahn racecraft about their super 20G but it is also a TD05 turbine

Super 20G

Model: TDO6H-20G-TDO5H-10CM2

Maximum HP Capacity: 500

Optimal HP Range: 300-450 HP

Mounting (turbine inlet)*: T3 style

Exhaust (turbine outlet)*: 3-bolt flange, part number H TZ-7180

Compressor Inlet: accepts 2 ½” hose

Compressor Outlet: accepts 2” hose

Oil Inlet*: 12 x 1.5mm straight thread

Oil Outlet*: 2-bolt flange, part number H TZ-7190

Optional water-cooling ports: included

Super 20G is a ‘hybrid’, similar in concept to the T3-T4 but vastly superior for street use due to its modern and efficient design. We use a TDO5H-10cm2 turbine section mated to a TDO6H-20G compressor. The result is a unit that will support up to 500HP, yet delivers the best low-speed street characteristics available for such power capability. Like the Super 16G, it’s also a good choice for stock engines that will be upgraded internally later, as it can be run at low boost levels safe for a stock engine (typically 5-8 PSI), then turned up later after you improve the engine’s internals. The internal wastegate is super-effective, and can be ordered with your choice of adjustable wastegate actuators (click here). These actuators are also available separately should you decide to change boost levels in the future.

I am a little lery of using Kinugawa again, but it may be my only option. Which of these would be the best option?

Understandable,
this one looks better, http://shopping.kinugawaturbo.com/kinugawaturbohyundaigenesistd05h16g300ps-3-1-1-1-1-1-1-1-2-1.aspx but, it appears to have only an 8CM turbine housing.

Ask them if they have different turbine housings like a 10, 12 or 14 CM.

The 8 CM housing is restrictive, but since it has the larger "H" turbine wheel, it will breathe better than a stock non "H" wheel.

I have used a 10 CM turbine housing on my stock 20G turbo. It would spool just as fast as a stock turbo, but once it saw boost, the boost came in faster. I never tried that combo @ a track, it seemed a bit faster top end, but not sure if I would have been faster than my previous times @ a track of 12.29 & 12.31 w/the stock turbo.

I now use a TD06H turbine wheel w/a 60-1 compressor wheel & a 12 CM turbine housing. Current best of 12.0 stock long block, stock torque converter.
I use the 12 CM turbine housing because I still have the stock torque converter. I also have a stiffer wastegate actuator 15 psi base boost pressure. This helps tremendously!
IMO, it (the 12 CM housing) is the largest turbine housing to use (w/stock torque converter) & still have great street ability & not have bad turbo lag as you would when using a 14 CM housing.:2cents:

Later,(who knows when:roll:) when I change my torque converter to a little bit higher stall, I will use the standard 14 CM turbine housing.

Question, what stall torque converter do you plan on using, refresh us on what are the specs on your new build?, camshaft specs? Vehicle it is going in, weight etc.

When you say you want 450HP that is at the crankshaft?
My 396 HP was @ the rear wheels.

Undetermined
Pistons (I'm open to suggestions)
Cam will be custom ground Comp Cams (I'm open to suggestions)

My goal is to make ~400 RWHP

Sure thing, you are welcome, I try to help out if I can.

I would like to see Kinugawa sell a 60-1 turbo w/an "H" turbine wheel, but w/there higher flowing 9 bladed "H" wheel http://shopping.kinugawaturbo.com/t...sl220g11bladesubarudsmlighter9blades-1-1.aspx & they should offer different sized turbine housings, like a 10, 12, & a 14 CM, that would be great!,
But it seems they only have 8 CM turbine housings.
I believe you also can have a choice of different psi wastegate actuators also. You would need to tell then what psi actuator you want.

Who knows, maybe Kinugawa reads from our forum?;)

Re: Pistons suggestions for a Turbo Vortec 4.3L

I sent an e-mail asking if the SyTy TD06H 60-1 (0100-837-524) can be ordered with a 10-14 cm2 housing and the 9 blade turbine (406-02015-003).

I guess we'll see if they will reply back.

Re: Pistons suggestions for a Turbo Vortec 4.3L

I received the following today via e-mail

Hi Kenneth,

I can offer the turbo with 9 blades wheel but I just have the 8 cm turbine
housing.
The turbo with T3 / v-band 10cm is available if you need it.

Regards,
Bruce
