Pretty sure they are all based onE85 runs are on External gate with high mount manifold.

Recent results are, yes.

But the G3 is an 'old' design. Original results (the ones I used when I bought my turbo) were on the stock manifold, internal gate, and 98 pump fuel. Just wanting to see if I can compare my turbo to these results without estimating, I don't think I can.

Highmount/external by looks, i want to see internal gate 56T vs 58T on stock manifold, thats what most people have/buy..

Also going back to the 56t, originally you where saying the 58t needed cams for more power from memory,

but going back to 56T and still giving samish results, have you actually run out of turbine flow?

cheers

Doubtful... Its close to a 90 trim 60mm wheel.

Just want to give Stao some props on his turbos. I recently installed an ATR28G2 SS1PU to my sr20. Car has 180k and is unopened with all the usual bolt on's. I was running 18 psi and getting 226rwkw, no cams and it felt pretty good. I just whacked on a bellmouth dump and upped pressure to 20 psi and the car pulled 236rwkw.

What really blew me away was the change in mid-range from about 4500rpm, it feels like a different turbo, noticeably more torque. I winder what it will do with cams, New HG, head studs and 24 psi?? All I can say is great product, great performance and great price,keep up the great work Stao..

great to see another good SR SS1PU result!

who tuned it Morgan?

Tom at PZP. That guys awesome, knows his stuff and always has the time to answer questions.

I cant recommend him enough.

The turbine can flow plentiful, it is a larger trimmed turbine originally engineered to use with small housinged high flows.

With the stock exhaust manifold, I can't get any thing pass 322rwkws on e85 (-40kws=98 power), and that is a SS2 turbo making 375rwkws on a proper high mount externally gated. So there isn't much more I can do apart from modifying the actual manifold or build turbos that shifts boost curve band n forward.

To compare result with pump 98 internally gated simply:

Power:

High mount E85 result - 40Kws from E85 - 15Kws External gate

So the new G3 would make:

376 - 40 - 15 = 321rwkws On pump 98 internally gated with a free flow exhaust manifold and exhaust setup.

Using factory manifold it will cap maximum power output to the 280rwkws mark. But

Factory log manifold produces better response, in comparison by 150rpms. So G3 can do 280rwkws @ 20psi by 3750RPMs.

Latest G3 results look unreal... :woot: are ther still plans for a 73mm comped td06 l2.

Nice work Stao

Probably a 76mm wheel with complete G3 housing assembly. If I can get the SL2 to produce 376rwkws without revving passing 7000rpms with 20psi by 3500rpms would be pretty sweet.

Thanks for the feedbacks. Will be looking forward to see you results with some cams.

That sounds good.cant wait

Didn't that fab dude that does all the lobster pipes, go a a easy 350rwkw on 20psi on standard mani on a G3 on E85

ages ago?, now he has a ss2 , and he wasn't the only one?

Out of interest any thoughts why do you think the 56t performs so well compared to 58T if your not out of turbine flow and theres no restrictions else where?

cheers

Yes that is Abe. He's spent lots of time die-grinding all the ports of the stock manifold. Can't get his result with a stock manifold.

58T in theory should be making more because it has larger inducing area. How ever the car was out dated for a service using 8000km old engine oil. Recent runs were done straight after a service. Have to admit my car drove heaps better with fresh oil too. That part is arguable.

My main concern is better transition and throttle response, and the current version satisfy that criteria.

I'm going to try out the atr28g2 soon on my sr20det soon once I get a fnt housing off stao big boost 22 to 24 psi e85 Poncams

Just want to have one more run to see the best time I can get with the kando and Ill do the turbo swap over

Hopefully it will make similar power than I am now on less boost and better response cause the fnt and bigger compressor than the tdo5h18g

I'll get Unigroup to print me a back to back comparison and post it up once done and I'll be testing it put at wsid aswell

Yeh i 100% agree you've done the right thing, just had me a bit puzzled on the outcome really

Ok. as already been posted in the 400rwkws group, I've also trailed the ball bearing ATR45, or also called the ATR43 G4 profile for the Rb bolton series. This turbocharger is not responsive but ended up making 431rwkws @ 26psi. Pretty scary, foot down in 3rd and 4th, feels like the incoming air resistance is about to tear the whole car apart. It jumps from 120km/h to some where around 210km/h (stock cluster) in a blink of an eye. The RSR tyres held pretty wheel with a little wheel spin in 3rd and held all the way through 4th. mid top torque is crazy. I think this turbo can pull some series quarter mile times.

Tuning video:

I've pretty much decided to go with a Hypergear highflow service for my car, but wanted a bit of final confirmation/recommendation before I proceed...

The car:
'99 C34s2 RS4-S Stagea

Mods:
Greddy Front Mount Intercooler
3" Full stainless steel Fujitsubo exhaust and stainless steel front pipe with 3" Venom 200cpi hi-flow cat
Nistune ECU
Turbosmart Boost Tee
Nismo High-Flow Volume Fuel Pump
HKS Panel Filter

Possible future mods: Z32 AFM and larger injectors

My thoughts are to go for the PU Highflow service, to give me some headroom for future mods. Is there a better option?

I'm looking for good response and useable power. The car is my daily driver, not a track car.

See below the graph from my most recent tune...

Also - I'm on the look out for an OP6 to send in for this, so that I can keep driving my car.

I think the SS1PU is abit small for the Stagea as the engine is tolling a much heavier car. I think the billet SS2 or the roller bearing G3 would be a perfect turbocharger for this vehicle if it has to be a brand new turbocharger. Alternatively highflowing standard OP6 turbocharger is also a good option.

I'm in a similar boat (geddit, boat? :D ) and will go the SS2 or, more likely, G3. It's not a daily so I'm not concerned about lag which is why I'm leaning towards the G3.

I just need to sort out my injector choice before buying the turbo. My kingdom for a simple 1000cc injector solution for a Neo!

What's so hard to work out? The Neo is already 14mm topfeed.

    • Yeah i found that alot of parts can be wrong or "very" hard to get the real right one. I already bought some brakes years ago on me "old" GT calipers and they were wrong too 😄  I told them too. Even send them pictures...but they said "EBC catalogue has them on my car... So i dont know what their answer will be. I call monday them and let them know that they are really not on my car. If they were they would be already on a car...
    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
