2G Turbo upgrade 16G x 16K X 18G or 20g?

[Dan Rittner]

Hey guys,

It´s been a while since I am looking for a direct placement new turbo.

So basically, my car is 98 GST that came with an ebay crap 16g, it has stock internals and all mods necessary (FMIC, FIC 800 injectors, DSM Link V3, Walbro 255 pump, and BOV), ima looking for that safe 350whp that as far as research is safe for the stock internals, the car is running on E85.

I´m in Brazil and lots of vendors don´t ship here. Kinugawa does, and it seems they changed a lot from being another cheap knockoff turbo to something actually pretty decent, however, they have a bunch of different options. For every single turbo, I mentioned in the title they have:

- Journal Bearing
- Ball Bearing (is it any worth a 16 or 18g with it?)
- Turbines with 12 blades, 9 blades STS, 11 blades STS 55
- Compressors with 6+6 (cast or billet) or 11 (billet)

Here is the so-called STS information: https://store.kinugawaturbosystems.com/blogs/q-a/whats-sts-superior-turbine-strike-advanced

And I didn´t even know such a thing as 16K existed. Which was the one that caught my attention.
Anyway, I thinking about either de G or K billet 6+6, not sure about the STS blades.

Please any help and thoughts here?

The company has very little information posted about itself, its products, or its engineering.

Simply put you may just be getting an ebay 16g with a kinugawa stamp on it.

They show no photos of assembly of product or quality control, or actual pictures of their ball bearing turbo. Their ball bearing turbos still need to be oil and coolant feed

Their description of a 16k turbo is simply stated as a 68mm compressor wheel


Their pricing is very very high for the product they sell, with very very little data available for their quality.

Extreme PSI ships worldwide, not sure how much you would end up spending on shipping + import duties, but they have a good deal on MHI Evo3 turbos

I personally run their 25g turbo. I believe it is td06 10cm housing but I’d have to check on the cm. I know it’s td06 though. It’s a journal bearing with the 6+6 wheel. I don’t run coolant through it.

I can say that the quality is much higher than just a cheap eBay one. It came with an adjustable internal gate that I removed and welded the housing shut where the flapper went through. I run an external 38mm on the o2 housing.

It runs at about 23 psi right now and will be going up about 5 more psi after I get my car switched to e85.

So far I can’t complain. For the money you can pretty much get a FP green but everybody runs one of them and I just wanted to be different and try it out. But seeing how you can’t get one due to shipping I’d go for it. Can’t comment on the other turbos you’re looking at though as I have no experience with them. Maybe Justin will comment and tell you they are junk. I’d take his word over mine.

That´s the problem lack of information, although at least from a marketing standpoint they improved a lot.

I was considering them until I spoke to Kinugawa and they cover shipping and any import duties which is 60% when it happens. (because not everything goes through customs due to the high volume of stuff coming to the country)

For how long have you been using it?
And most important what type of use?

It’s been about 2 years maybe 1,000 miles. I don’t drive the car often. I go for like 20 miles cruises here and there. So it does see full boost quite often when I do drive it. Last time I checked though it didnt have any excessive shaft play.

Do I consider myself one to beat the piss out of my car. Absolutely not. Time will tell how it does but from what I can tell I expect it to keep doing it’s job.

I change my oil and filter every spring too. If I was to do every 3,000 miles or something like that it would be in there for several years which I don’t like

Kinda like me, on the average I drive 60 miles per week I do some short rolling pulls and pretty much thats it. I just like the feeling of the turbo getting boost, listen that sound and the accelaration. Id day Im very cautious with my car.

No ball bearing, no 9-blade turbines. Everything else is subjective to the build and the power level desired. Kinugawa is a distributor working directly with CHSH Turbo- their products are all made in Taiwan which means better than China, not as good as MHI. I've personally seen Arashi/Kinugawa 20G units with the 9-blade "STS" turbines fail before the 1000 mile mark (I've bought two cores in the past few months which did just that), and ball bearing has no benefit on a turbo that small whatsoever....if anything it just raises the initial cost and makes the unit impossible to find parts for in the event of a problem.

16KX is likely a copy of the MHI compressor for the factory Subaru upgrade. I have no experience with that specific wheel but it's only 1mm larger than a 16G and it's a thick-hub wheel so I wouldn't expect. In reality a MHI Evo III 16G is likely a better turbocharger with greater durability and power potential.

Steer clear of anything "25G" if you can. In my experience the 25G compressor profile seems to work very poorly at high pressure ratios...I'm not sure if it's the trim or blade profile but it's a 60mm turbo that barely outperforms a 52mm 20G at high pressure. I've seen them in action on both DSM's and Evos and the result is never great compared to other options that are considerably smaller. They do seem to work well at lower boost on other platforms with larger displacement, like the Syclone/Typhoon...but for a DSM or Evo I consider them as not an option.

I tried sending this as a PM, but since I am newbie, that is not allowed.

I am doing a 4G63 Headswap onto a 4G64 block in a Mitsubishi Mighty Max. I am now looking at turbo options and I've been advised to steer clear of CX Racing. I've also heard that you are the person to contact for a used or rebuilt turbo. Do you have anything available or can you make a recommendation?
I'm running 9:1 compression with Wiseco .030 pistons and Eagle H beam rods. I'd like to see about 350rhp if possible.

Thanks for taking the time to read and any recommendations you can make.

I have a 1992 mighty max I want to do that head swap on and de stroke it could you please explain what all was involved? I want to turbo mine as well bust first want to figure out the head swap

Let's try not to hijack threads guys, but this might help with the head swap in terms of info: https://projectzerog.com/
