Test run on the Rb bolton internally gated ATR45SAT turbocharger, the external gate has made a huge difference in power gain.  Final result of 362rwkws @ 20psi Internally gated  and 427rwkws @ 25psi Externally gated

Thanks all for all the help, I have most of the main pieces of the puzzle ready to go now. 

ATR45SAT-BB (thanks Tao, she's a little cutie), 1000cc injectors, 460l pump, HPX-N1 maf, Nistunes off getting updated to feature pack 2.1 + having the flex fuel gear installed.

Only hard bit now is the intake piping, which I'm hoping I can just get fabricated by whoever installs it to make life nice and easy. Save me doing bits, towing it to a fabricator, then towing it to a tuner etc. if possible.

On that note, Any recommendations for an installer/tuner in QLD?

Where are you located? In Brisbane I recommend East Coast Customs & Townsville either myself or ShaneFraserMotorsport. A quick google of nistune tuners is a good place to start too

i  like the way in 1000rpm an extra 350kw comes on line, that will be interesting to drive!

965Mn of torque. No traction in 4th gear. In the process of getting MT ET at moment.

Hi all, after reading 615 pages I’m still confused on which turbo to buy 🤦‍♂️ I have a unopened rb25 neo, fmic, I have a link ecu and a 6 boost manifold waiting to go in, would I be better off with the ART43G3SAT or go for the g3 .82 bb version I have my eye on 750cc injectors to go with it. 
 

cheers

Without telling us what your looking for no one can really make a recommendation. How about starting with how much power you want to make and what you'll be using the car for? Street/circuit/drift/drag/etc... 

Also if your going e85 you'll run out of injectors with only 750cc.

Hi,

I’m looking for anything around the 400-450 bhp mark.. I’m not looking to go forged yet ( maybe in the future) its a road car and the odd drift day. I won’t be going e85 as it’s hard to find in Ireland as it was phased out a few years ago, so it will be regular unleaded  for the c35 laurel ⛽️,   On a side note I have a bio power 9-5 and it’s a shame I can’t get e85 for that too

For 400~450HP mark on P98 fuel I recommend our externally gated ATR43SS2 in .63 rear housing T3 Vband. I can supply external gate exhaust manifold and turbo smart gate assembly with screamer with the turbocharger if needed.

Hi, is the engine in this test still on OEM stock valve springs? thank you.

[hypergear]

No. it had performance springs valve springs.  You can also use Supertech valve springs.  Both worked fine.

[CefiroA31]

Ok, thank you for clearing that.

[hypergear]

Pretty cool result to share. ATR43SS-2 BB on a Rb25de+T Neo cracking 390rwkws on E85 fuel on KeepRite drifting machine. Tuned at Dr.Drift.

Hi Hypergear, 

I am interested in a 600rwhp capable turbocharger for my built rb25 neo engine 9:1 compression ratio. Will be running a 6 boost manifold (would you suggest a t3/t4 or a v-band inlet?). 

What would be the most responsive turbo you have in this range? 

Thank you.

[hypergear]

Hi Blakeo, That will be a similar engine build as my R34GTT. Recommended would be an ATR45SS-1 BB in .63 rear housing in T3 Vband out let. This turbo have managed to pull 520rwkws with stock cams on E85 fuel and making almost 300rwkws by 4000RPM. 

[hypergear]

Some more results to share, R34 GTR test and tune, I've had this cars in storage for awhile,  if you did spent 250K for a fully unmolested stock one today you will be horribly disappointed with its performance. Stock twins with upgraded cooler, exhaust, and intake managed to pull 238awkws at 15psi, with help of a PS2000 it managed 272awkws @ 17psi, Not fast at all. after getting chopped by a Supercharged TRD Camry, I've decided to do some work to it. And I still believe Rb25dets/Neo are way better engines.

 

 

 

Looking into further developments in T4 printed turbos. First up is a ball bearing ATR45SS-1 turbocharger in a custom T4 .86 Vband rear housing. Stock Rb26 engine is now fitted with:

APR head studs

HKS Cam gears +9" inlet, 0 exhaust.

R35 GTR coil packs

CAS Trigger kit

Haltec PS2000 ECU

ID 1650cc injectors

Twin 540 Walbro pumps+11m fuel line

Nismo Front mount cooler

T4 high mount exhaust manifold

HyperGear 50mm External gate

HyperGear ATR45SS1 T4 .86 rear

3 inches Trust turbo back exhaust

Final result so far 425kw on all 4 wheels @ 28psi E85 fuel

Tuned at Chequered tuning

Will be testing few different turbo combinations and spend more time with cam adjustments for better response.

Great result @hypergear I also think that Trust cat back is a restriction, probably has a restrictor hidden somewhere to make it JASMA approved 

[hypergear]

Thanks for the tip. Yes I though it might be the case, so I've added a cut out on the front pipe. Highly recommended for power hunting.
