Looking to spend $500 to do that sleeve insert. 

One more Tuning video to add. This is one of our ATR43G3SAT Rb bolton models. making 324rwkws on E85 fuel internally gated.

Car's an R33 GTST with:

Stock RB25DET
Stock intake manifold with FF throttle body conversion 
FMIC
Hypergear ATR Series bolt on turbo with IWG
Stock exhaust manifold 
3" TBE
Aeroflow top feed fuel rail conversion and Bosch 1000cc injectors
Walbro 460LPH fuel pump 
EBC
Flex sensor 
Haltech Platinum pro plug in ECUPrepped by Hadie from Elite Motorsport

Can you please share some dyno data of the T51r anti surge slot showing?
Specifically after before and after the slot install ?

[hypergear]

It acts as a normal anti surge slot. There is a lose in compressor efficiency. I did a comparison years ago result is in this thread. There was a lose of 300RPM and 11kws with that particular turbo used.

Tao, I have a genuine low KM Trust TD06SL2-20G (8cm) off my RB20.
Going forged RB25 and cannot seem to sell it for reasonable money to fund a larger Turbo.

Worth doing a 10cm 20.5G or similar whilst I save for a big banger 25G?

Let me know if I should PM you

[hypergear]

The SL205 makes the same power as a 25G with better response. If your current turbo is not blown I can have that modified to the same specifications as the 20.5 with a 10cm with turbine housing supplied for less then half the cost of a new turbo.

More video to share. This is an R33 GTST powered by one of our ATR45SS1 turbochargers at Hitec drift last weekend. Car's currently making 401rwkws on E85.

One more result to share:

Rb25det NEO Stock engine

HyperGear high flowed Turbocharger
ID 1000cc injectors
Walbro 460L fuel pump

Power FC + Z32 AFM
Greedy Profect B EBC
600x300x81mm PWR Cooler kit
3inches turbo back exhaust
4inches intake pipe with Pod
Split fire coil packs

Turbosmart 45mm external gate welded on exhaust manifold.

 

At higher boost level we've reached 340rwkws before experiencing ignition break down.

further update with prototype ATR45ss turbocharger. Car made 364rwkws before running out fuel.

Looks like vct really helps these turbos come alive in mid range. Even though its a .63 the torque graph looks really good

Hey guys, just sharing a result.
Stock RB25DET, recent ( late last year) 21u highflow. 98 fuel. Vipec plug-in.
240rwkw on 14.5 psi.
264 on 17.5psi.

In the interest of stealthy looks, still running airbox, exhaust with functional cat and 2 mufflers. CES split dump, and a generic China cooler with custom return flow pipework.

Engine bay looks stock.

Putting more boost in gave more midrange, but tapered off to 17-18 up top, obviously either/ all due to airbox, cooler setup and exhaust. But happy with the stealthy looks for now.

Fairly happy with the result, car drives great.

[hypergear]

Nice result. The pressure drop would mainly be restriction on cold side. A FMIC with a better cooler, 4 inches metal intake and free flow exhaust should see another 10~15kws gain. 

[Pattey21]

The stock look is my ideal setup.

 

What intake pipe between turbo and airbox?

And what actuator and boost control?

The biggest you can fit using air box would be 3 inches, I would prefer a short 4 inches metal pipe in between. that provides better throttle response over 3 or 2.5 inches. Actuators, something 14psi or one of our high pressure actuators will do fine.

Ebay silicon one, as previously tried by Tao. Pretty much a drop in

14.5 psi actuator, boost control is a 3 port mac valve controlled by the vipec (ecu).

ATR45SS Rb25det NEO round 2 with fuel pump issue sorted. Now pulling 400rwkws at 24psi on E85 fuel. Car mods are listed in video below:

What would you expect out of this same setup on 98 octane?

[hypergear]

It would be around 350rwkws

[lexxi32]

It would be around 350rwkws

Would be interesting to see an overlay with the .63 .73 and .82 housings. Id imagine the .73 would match .63 for response maybe.

Is there much lost by plumbing in the wastegate with the 3 inch exhaust?
