I'm using Hypergear's SS2 in a .82 rear with a Nissan front cover making 297rwkws at 20psi full boost by 3800rpm. factory appearance, and completely bolt on.
-
I'm also running Hypergears atr43ss2 and can't recommend them enough. It might be helpful if you can indicate a HP you are chasing for and let people giving you advise based on that.

Catching up with the return flow cooler topic. Theoretically vacuum pressure at one point of exit is identical to all points of exit. I'm leaning towards manifold or gasket leaks and etc. On the same time your big cooler worked well. 1psi = 20kws
can't wait to see what it does at 24psi. -
OP's asking for a good bolt on turbo for his R32, by reading this thread there are whole lot of unrelated information that I'm confused.
The photo shopped result contain a mixed batch of E85 results, pump results, externally gated results, internally gated results, cam moded, plus results of a NA+T Rb25.
Filtering out all the unrelated. Take unopened Rb20det engine on pump fuel. I'm seeing hypergear's atr43ss has the best curve which made the most power on based boost level given. Turbo is direct bolt on that required little/none modifications, that will be the turbo I will be voting for.
-
Thats a big ass turbo. Great work. Looking forward to results.
-
Hypergear internally gated Rb turbos are definitely better, and so's externally gated. check out other member's results in their thread.
-
Looks like HG's latest TD0620G beat Kando's by 45kws. That would be a T67 power region without the lag, and better reliability.

@89CAL: From following hypergear's thread, I remember you've got one of their testing ball bearing ss2. I have the same turbo internally gated. Obviously not as responsive as the 2835 but pulled 312rwkws on 98 fuel, 20psi by 3800RPMs. Its more of a 3076 in .82 turbo. They have made an vnt housing for it, unfortunately only for external gate. Buy that housing and it will pulling 24psi on 3500rpms and that will be about the same or better to a HKS2835 ProS while making heaps more power.
-
Mine is in. still running the old .82 high flow tune on 17psi actuator pressure. More responsive and pulled HEAPs harder then the high flow. Can't wait to get it tuned. Will post up result once done.

I picked one up last week. Its about 10kgs.

Best to upgrade induction and exhaust first then play with the EBC as the end result will vary.
I'm posting up an promotion on our new ATR43SS-2 internally gated bolton turbochargers so more people can enjoy our latest development. The Retail price on this item is currently $1450, you can have own them now for $999 including braided oil feeding line. The Special offer is for 20 units only. That is currently the best performing RB25det bolton turbocharger.
Product details and Dyno results are:

Great pricing Stao, very tempted. I'm currently using one of your 3 years old G3 high flow making 285rwkws on pump, can more power can be made with SS2?
-
that sounds aright! i must look into these DIY videos, worth a watch i think.
have looked at walbro pumps too, forgot to mention. what benefits/disadvantages would i get from going to even bigger injectors?
i thought 550cc would be enough no?
The worst part was installing that cooler kit, which whole had to be cut and front bar had to be modified. Rest was pretty straight forward. You can buy no whole cooler kits nowadays. might make the job easier.
550cc is ok for 98 fuel, get ID1000 If you are looking to run on E85.
-
$5G is pretty alright. Below is what I've spent with my R34, I did all the work my self.
Split fire coil packs: $650
650cc Jecs injectors: $500
Walbro fuel pump: $210
Adaptronic plug in ecu and hypergear bolton turbo bundle: $2400
GKteck cooler kit: $400
Total: $4160
Dyno tune was $650 on top. Car made 285rwkws on 20psi.
P.s: about $100 worth of silicon hoses and a pod for a 3inch hard intake pipe.
-
Stao what about run a big compressor wheel in a small turbine housing then use a large internal waste gate to compensate heat and flow? I have seen few turbos from Euro cars been made that way like the Audi K03 and K04. Might be a good thing to try on.
-
LoL the turbo is probably older then you are so what do you think? Run it 13psi till it blows up then get it high flowed.
-
Any updates on the SR motor of yours Stao? my brother is looking one for his 180sx, tossing between one of yours, and a 3071.
-
2012 bro. I'm sure this turbo has been upgraded a million times since.
-
^^^^
I can only see boost curves. Seems like you've uploaded boost twice.
-
...
Other alternative for huge power with stock response is by using a welly tuned sequential twin system. I do have drawings to make that work and is probably the next thing on the trail list. Its going to get very expansive how ever, and I'm not sure how things might be fitted under the bonnet.
Do you mean similar to whats on the 2JZ Supras?
-
^^
Yes the ATR46 is some thing for that application.
Stock cams are back. Big thanks to: boostn0199 whom have donated a stock exhaust cam while mine broke. So factory cams are back in and working sweet.
Today's dyno run was trailing the newer version of ATR43SS4 Alpha turbocharger, not as huge as the previous one which I would like to call that the ATR43SS-5. I sort of like the power while it made based on the ATR45 (3540 equivalent) how ever couldn't get much drive ability out of it due to the lag. So this one is made to mach the HP as the ATR45 how ever with much better response, down low torque and on road drive ability.
So The final figure was 435rwkws @ 25.5psi and peeked 709Mn of torque. This is not at the maximum capability of this turbocharger how ever probably is for my current con-rods.
waoo 435rwkws with 200rwkws by 4000RPMs out of a Rb25det. Pretty crazy if you guys high flow a turbo to do this I high mount it. -
Check dyno sheet section for Hypergear's VNT roller bearing turbos. they are some thing that generates response in a totally different direction.
-
^^^
That is a very serious build for a KIA. I can imagine this kit with a ATRSS3 would be pushing towards 400rwkws on a SR20det !
-
Thats pretty decent response for power. looking forward to it.
-
just get a hypergears ss1, they comes with a nissan 6 bolt dump pattern, .64 turbine housing that makes full boost by 4k and 225rwkws internal gated with pump 98.
can't wait to see what it does at 24psi.

Turbo Options?

It didn't require a spacer. factory water lines and oil drain pipe bolt up fine.
