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

I was reading through the thread and was going to weigh in anyway, though looks like you're very much on the page I am reading from - so I'll +1 with with a bit more anecdotal evidence to support it

The ATR28SS15 would be a perfect turbo for your application. I didn't look into some thing even smaller as it doesn't make that much of a difference in response but did loses quite a lot of power. I'

^ lol... maybe I'll use a 3" intake pipe and add in more bends.. that usually gets the suuuuuuuuuuuuuuuutuuututuutut going LOL. Anyhow, some real world facts to back up the results.. errbody likes ti

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

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 :)

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.

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.5330FC90-D845-4773-9198-8280FDCB46F9.jpg

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.

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).

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

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

      I gotta pull you up on this. It's driving me crazy. A shutter is something that closes, like over a window or in a cmera. The word you want is shudder. That LSD is clearly f**ked. Take it to a diff shop and get it disassembled and examined by an expert. YOu might have plates welded together or something equally crazy.

      S1 rb25/s14 starting problem

      By GTSBoy · Posted

      Check the Nistune doco. There are a few assumptions being made here that might not be valid. I will list the things that occur to me: Base map. Base map for what? Base map for Z32? Then the cranking pulse width is probably wrong for an RB25. The extra 500cc of capacity might well be enough to prevent it from catching. Base map for RB25? I don't think you can load one of those into a Z32. You have to just make the settings correct for an RB25 in the Z32 base map. That is either K or the TIM to get the pulsewidth right. Loom. You bought a loom for an RB. And you plugged it into a Z32 ECU. Did you make sure that any iwre differences were swapped. From memory, there's at least a couple. And as per the others, I would suggest making sure that the fuel pressure is correct while cranking and that the injectors are actually flowing as expected. They really must come out and go on the bench, unless you do find that you have messed up as per above points. I would also suggest watching in Nistune to make sure that everything is reading correctly. That the correct binary flags are raised at the right time (like the crank signal), that there's no stupid values in K or TIM. That you have not got mismatched firmware for the ECU and/or a wrong image loaded.
