Yep ! That was extremely bad , I would edit the post but can not work out how from my I phone .

We sponsored topstages S14 for wtac this year, its an built sr20det with solid head and pro cams. Upgraded to our ATR43SAT turbocharger from Garrett GT3071. Car made more power through out the whole rev range and maxed at 381rwkws e85 fuel.

 

Red: Atr43sat

Green: Gt3071

Philip island test run:

what about the atr45sat  result on the same car...

cheers

Haha, the car had upgraded fuel pump later on so I upsized the turbo to an ATR45SAT which made 408rwkws on an aggressive tune. Backed to 399rwkws for tracks. It run 1.251 at Winston last week beating previous wtac winners result of 1.26

That torque rise looks awesome! Nearly vertical!

[jet_r31]

How much boost for 408rwkw Tao?...and did it have much left?..

I would have thought it would be good for 30+psi on a non VE  headed sr20

cheers

Was 24peek. Still using built in 20psi map sensor.

ahh so map sensor stopped you, turbo should have a fair bit left ?

I think 420rwkws is about the most this turbo can do. have to upsize wheels for more power. But Its plenty for what this car needs so far.

[jet_r31]

Same turbine and exhaust housing as RB version?

Be interesting to see a atr45sat SS version on a sr20..

 

cheers

Hi all.
I'm about to order the atr43sat for a 25. Looking to make 450-500rwhp Questions are:
Can that be had internally gated through standard dump?
If I need to change dump etc might as well go ex-gate yeah?

[hypergear]

For this power. its best order our ATR45SAT in BB CHRA. Run it externally gated with gate mounted on factory manifold.

Hi mate, what are you able to get out of a vq30det turbo hi-flow on an rb25 Rb26 etc?  what sort of rwkw can you get from it?

[hypergear]

Better getting a stock rb25 or neo turbo high flowed to suit.

Speaking of Non VCT, low cr engines, did you ever end up doing any development with an RB20 Tao?

There are so few of them around and took a while to find the right car. Picked up a 93 model R32 GTS4 in good mechanical order. Will be starting developments based on R32 Rb20det engines. My goal is to 270rwkws on pump 98 fuel with good turbo response.

Car is pretty basic with a return flow cooler, and a turbo back exhaust fitted. I will be Nistune it and drop in some ID injectors for starters. I will list prices and places as project move along.

[CEF33Y]

Eagerly awaiting your results!

Here I was about to change to a RB25..... haha.

[hypergear]

haha true, my plain is to drop in a RB25det NEO motor off a Stagea in it later on, Nissan should've done that years ago.

I will be using our ATR43SS1 as well as doing some high flows, and see if there are room for improvements.

[jet_r31]

Lol you beat me to it. Was going to say after you stop playing with the rb20.

Put a rb30 in it with rb25neo head..and a big atr45 ss 67mm turbo...easy 10 sec streeter..

Cheers

Will be moving to a new ATR45SAT Ball Bearing soon.
Will put results up here once dynoed.
Below is what im going from -> to.

ATR43SS2+ gate off housing - > ATR45SAT BB
Stock ExhaustMani - > D2 Stable High Mount + Gate of mani
44mm Tial Gate - > 50mm Turbosmart Gate
Stock Plenum - > Custom FFP + Sard Fuel Reg
Single 460 Walbro - > Probably Surge tank
Nistune ECU - > Adaptronic ECU +Wideband/Airtemp sensor
Z32 AFM - > MAP inside adaptronic
E85 - > Still E85
Stock Head - > Only doing ARP headbolts
And a bunch of other random stuff

Was ~450 hp at the rears - > Hoping for + 550 hp at the rears

Current full boost is around 3800 @ 20-21 psi
Im hoping for similar response, looks like it will be close.
