This is a review of the http://on3performance.com/ billet Ball Bearing 67mm turbo.

I picked up a set of these turbos after having good luck with On3's standard bearing turbos in the past. I wanted something affordable, but with some modern amenities and updated aero wheels. I sold PTE, Turbonetics, FP, and Garrett turbos from 2003-11 so I saw the huge improvements turbine and compressor wheel designs have made over the years in moving air with great er efficiency. On3's billet line up on paper gives a great gap between improved efficiency and cost. Similar turbos sell for $2200+in ball bearing form

These are the turbos I have purchased

It came packaged well with super janky instructions. Really, if you need instructions you should not be buying a turbo at all.

Turbo was perfectly clean and preoiled.

The Compressor is obviously machined billet AL and not cast, as is the backing plate which is a great sign of quality. Both Compressor and turbine wheels were balanced (I verified the rear of the compressor was balanced with material removed) I did not check the dynamic balance of the assembly as I don't have the $250k machine to do it.

Wheel specs were sent as follows

Compressor:

Inducer: 66.6mm
Exducer: 84mm
Inlet: 100mm
Outlet: 62.5mm

Exhaust:

Flange: T4
Outlet: 3” Vband
A/R: .81
Inducer: 74.2mm
Exducer: 64.5mm

And checked out





The Compressor is definitely updated tech with a thin center shank and much larger, longer, and more swept blade area. It also has an airfoil profile unlike most cast turbos which are just a uniform piece of material. Compared to the GT45 everyone loves


And a GT42


It does not take an engineer to see what compressor is going to move air more efficiently.

The turbine wheels looks more like the Aero shape of Garret's GT turbine, which is GREAT news! This is compared to a China GT45 (top) and a Garrett T31 turbine of a 60-1 (left)




Most people don't realize when the GT35r came out and crushed everything in the 6xmm arena, all they did was change the turbine and used the same compressor (very, very slightly reworked) as their previous T-61. People were bolting these on and gaining 60-80whp all from turbine efficiency. So, I am happy to see that technology used/mimicked here.

You can hear and feel the BB CHRA. Its not as loud as a Garrett CHRA which uses steel BB's, but its obvious especially when compared side by side to a STD Bearing unit.

Another nice touch is a true unique identifier. I dont know if anyone is actually keeping track here, but again its nice to see!


All and all, I am 110% happy with my purchase. These are by FAR the nicest "Chinese" turbo I have ever seen, and I have had 100's pass through my hands over the years. You can buy 2 for less than one of its competitors, all with a true BB CHRA. Also, its interesting that these wheels seem to be true one-off units, as they don't match any of PTE/COMP/FP or Turbonetics wheels I have seen or can find in the directory, and are obviously not BW/Schwitzer copies.

Funny thing is, this is about the turbo I asked PTE to build in 2008 (6762) for a TT Supra set up and they would not do it. Glad Chad found someone that would!! With the turbine wheel/housing sizing, I think this would work great on a 4 banger as well and will test one on a Mitsu or Honda in the next few months hopefully.


I have about 300 miles on these now, and the still have ZERO shaft play, same as they came out of the box. The are very responsive and I can see full boost in all gears on a stock 5.7 (twins), and positive manifold pressure @1600 rpm in 4th. I will be installing the rest of my fueling soon, and will have dyno charts available as soon as I build an intercooler set up.

Any questions feel free to ask. I hope this helps some people considering this option since its a new turbo to the market.

 

On3 starting making Mustang turbo kits 5-6 years ago. You could get the standard Chinese junk or upgrade to Masterpower for a little more money.

There are quality things made in China. We used to work with a Chinese pipe mill and imported 10's of millions of dollars worth of product that was half the price of domestic, had superior metallurgy, and tighter tolerances.

Nice to see On3 has stepped their game up.

 

Yes, its nice to see such a quality turbo @ a great price. I think power wise it will make 6266 Numbers with slightly better spool. I think Maxed out a 6766 will make more power, but for the $1400 discount, I'll stick with the Billet On3!

 

How much is this turbo?

 

check the ebay link in my OP

 

If only they made smaller turbos...

AKA GT28/30

 

I'm pretty sure they make Billet BB 58 and 61mm turbos as well. You'd have to call them about that though.

 

I second the need for a smaller frame turbo in the 2871-3076 range.

It would be interesting to see how they would perform.. especially with the price point.

 

He does sell 30 and 35r clones now-with V band turbines!!

As an update the set up has been sold. I was made an offer I could not refuse! The new owner will be keeping up with the thread here. Hope to see one of these on a Honda soon hurting some feeling in the dollar per HP catagory here!

Nice to see them go beyond the typical china effort
