My GTRS turbo's arrived today. I took some snaps to show all. I am really happy with the GTRS kit, everything included.

(Sorry but I could not post up the jpg's)

Anyway, they go onto the car Next monday and hopefully the car gets tuned before the drift day.

I hope to get the car tuned thursday next week.

I will probably stop at 1.2bar as I dont drag, just track days

I'm sorry but you musn't be looking in the right places if you beleive there isn't much info on GT-RS turbines on the RB26?!?!?! *baffle*

In fact, i think there is ONLY info available from manufacturers about the RB26 and the SR20.

Freely available on the manufacturers site :(

Yeh there is info from manufacturers, but next to no feedback from owners in Aus of GTRs with these turbos fitted...i think that more what he meant. :(

Cant wait to see how your car goes with these turbos, perhaps with all this grunt its time you spend some coin on new shocks? :)

Does the kit come with its own wastegate actuators? and do these turbos bolt up to the standard HKS dump pipes or do they have there own dump pipes because the wastegate outlet looks different to all the other GT25 series turbos the wastegate does not look completely seperate from the turbine wheel

Yep, they come with their own internal wastegate actuators - as pictured set at 0.9 bar. The wastegate outlet looks different because there is a 'splitter' to stop turbulance from the main exhaust outlet. They will still bolt up to the standard T25 5 bolt dump pipe.

Well the turbo's are on and feel nice. Lots more low down torque and agressive top end. With a new set of plugs it is a new car!

I have only been to 1bar but felt very strong, I am very happy. Dyno tomorrow and check the Fuel:Air and see what power I get once the PFC is tunned. I am looking for more of a fat curve that a peak power curve. Usable power is the key for me.

The only negatives, the turbo's are a little louder that the standards and really scream once they are spooled up. Also the waste gate has a vent at about .8 Bar so I cant drop the boost when the wife drives. Oh well, as small price to pay. So far 5 star rate on the turbo's

    • GTSBoy on your suggestion on another thread I had a look at those injectors and ended up getting them because of the quality.  Got the expensive ones.  
    • Hey guys been looking everywhere to try and find the correct gtr hood latch support part number but only found the first half and when I search with that number it sends me to an r34. The first part I found was 62515. If anyone could help me with the rest then I’d really appreciate it. Or if there’s some alternative hood latch support that would work even better cause I can’t find any for sale. (Searched on upgarage, partsouq,buyee,rhdjapan) 
    • If you've only done the upper control arms on the rear, AND you have changed their length (by more than about 1mm) to set the camber you want, then you will definitely need/want to install traction arms also. Adjusting the camber arms on their own WILL introduce bump steer and make the car unpleasant to drive. Most owners have no idea that their car could behave infinitely better than what they put up with. I'm not entirely sure what the Stageas need, but I am thinking that unless you have massive front spring rates and pretty soft rear springs, you have waaaay too much rear bar. Oversteer city, in my estimation. Combined with possible excessive bump steer from maladjusted arms, that could be a recipe for nastiness. ATR43SS2 is not a highflow. It is an outright replacement turbo. It's a little bit bigger than the largest highflow profile that Tao does. Probably a solid 300rwkW turbo where the bigger highflows will be about 30-40rwkW less. Nevertheless, we're only talking about ~300 rwkW, which is well within the abilities of the stock ECu to run with a Nistune on board. I would do so without hesitation - and I will be doing so when I get my finger out and actually get the injectors and AFM installed. But, if you would prefer to drop a whole lot more money on the ECU side, then I suspect you're looking at Haltech. The Haltech fanbois here will all spout on about all the available engine protection you can have, that you can't have with the Nistune option. And they're right. But it doesn't really come for free either. You will spend more money on extra sensors and the like, plus the work to install them. If the engine was built and therefore represented a big investment to protect, then I'd say definitely do it. If you view the current (and forever into the future) shortage of replacement engines as something to prompt similar protection, then also, do it. If you see a destroyed RB25 as an opportunity to put in a Mercedes or other V12 (like I kinda do)... then your perception of the risk/reward might differ. These are good injectors. You can also get a "better" set of the same with more flow matching, for more $$. 1000cc is where you will want to be. You will need an R35 AFM and adapter tube if you want to stay with Nistuned stock ECU. Otherwise, if going Haltech, you can ignore. As for intercooler. Just about anything will do. You're only talking about ~300rwkW. Just put a big core in there. Be aware that return flows do add significant pressure drop and will cost power and will make the turbo work harder to achieve the same goals. If you can manage a proper crossflow, do it. I'm keeping my very good return flow because I'm only expecting to be in the ~250rwkW range, and will live with whatever outcome I get.
    • I have a heap that i have collected if you want some authentic ones still. Pm me if your interested!
