WIP:

Ceramic roller bearing SS-4 Turbocharger prototype 1. I've made two types of comp wheels and 3 types of turbine wheels to trail and the profile with the best result will be released. It will be running a .82 Alpha turbine housing.

I'm targeting about 480rwkws mark with the new cams and E85 with 20psi around 4500RPMs. Assume my 850cc injectors don't run out and nothing breaks.

I was reading through the thread and was going to weigh in anyway, though looks like you're very much on the page I am reading from - so I'll +1 with with a bit more anecdotal evidence to support it

The ATR28SS15 would be a perfect turbo for your application. I didn't look into some thing even smaller as it doesn't make that much of a difference in response but did loses quite a lot of power. I'

^ lol... maybe I'll use a 3" intake pipe and add in more bends.. that usually gets the suuuuuuuuuuuuuuuutuuututuutut going LOL. Anyhow, some real world facts to back up the results.. errbody likes ti

This particular one will cost $2500 to build. how ever I will have it configurated to be the most responsive turbocharger in its HP range.

He did say that's assuming he doesn't run out of injectors, so it's likely he knows he probably will and is going to see where the but stops before he outlays on new ones.

Stao just so you know I am doing great with my Five-o injectors, a set will run you under $600 for the RB25 and come in sizes up to 1200 for factory fit.

BTW I will probably be adding an external gate to my combo so will have some room to add a VNT housing if you would like me to trial. Drop me a PM.

Using these two calculators I get you would need 940cc/min @ 90% duty...

The current injectors started to run lean on 431rwkw, probably be out towards 450rwkws or might not get there. Will shop for larger injectors.

I will also be targeting response just like other Alpha series turbochargers. Its cool if I ended up with the most responsive 430rwkws.

Result of our recent high flowed R34 OP6 turbocharger. This turbocharger is using our upgraded high flow profile.

Tuned by Toshi on a Mainline roller dyno, made 270rwkws on 18psi of boost with factory actuator pump 98 fuel. By judging the shape of both boost and power curves this turbocharger is capable of running higher boost then what it has been set to. at 22psi is should be getting very close to 300rwkws mark.

Further updates. Just completed the SS3 Alpha prototype-1. There is a dealt about compressor surging using a wheel in this size with fall over blade design, specially working with VNT turbine. So I've made two set of sleeves that goes into the current compressor housing. One is anti surge while the other one is normal. If Trent has time we will be trailing the affect of having an anti surge compressor housing.

That's an interesting way to get the ported shroud in a normally plain housing . I's something that I'd like to see with T04E housings as well because it seems like HKS and Garrett are the only ones with port shrouded E housings to suit Garrett wheels .

Love the bullet nut and overall look of the turbo. Starting to put out some awesome looking turbos

I'm interested in the effects of the anti surge. Its probably at least semi useful on that turbo but I'm not sure why HKS decided my little turbo needed it.

Turbo is installed and I've taken it for a quick test drive, untuned. Well its not responsive as the other alpha series turbochargers, How ever is very responsive for its size. Even it is bigger, but much more driveable compare to the ATR45. I've taken a small footage of the turbocharger on idle then shutting down. While the ATR45 didn't spin much on idle.

Hi Stao,

Just a question about your brae manifold, was your made special in terms of the wastegate position or did you just use the normal one that they make? Also how much for one of your 50mm gates?

If you are getting him to make you one you should be able to have it where you like :)

Stao,

You should get a stencil made up and spray on your name "HYPERGEAR" on the compressor cover. Or some other way. Very interested to see the effect of anti-surge.

Josh.

Yeah I know but I just wanted to get it same as Staos run since hes tested it and shown it works well.

      Haha luckily we don't have emissions, inspections, or any laws against power adders here. They only thing they somewhat keep an eye out for are ridiculously loud exhausts.

      Just wanted to pop in an update on my setup. The CD swap has been great, I love the mazworks housing for the overall simplicity. I ended up sealing my trans tunnel with a thin sheet of aluminum reused some of the holes on the trans tunnel, and laid some window sealing EPS foam around the edges. Works great, really quieted things down and sealed up the car.  As for the power comment. Right now I am also running about 650whp. with the way the bell housing is attached to the face of the transmission I have zero doubts it would be fine, mainly because the input shaft and main shaft bearings are seated into the bell housing adapter. This means the load is NOT on the bolts to maintain the power, rather into he casing of the bell housing; Yes the bolts are doing some work there, but with both shafts locked in zero worries.  End of the day, the Mazworks solution is the easiest and safest. no need to take your trans to a shop to get milled perfectly, it fits with minimal clearancing, and you can use all your existing clutch and flywheel.  Driving wise the CD has been great compared to the big box, I'll probably swap my final drive at some point. The serial 9 shifter is gooooood, my only qualm is how tight it is, it takes a fair bit to get use to, 5th and 6th are a bit eh/hard to find at times, but maybe I need re-adjusting, and I think my clutch master is very tired and needs a rebuild.

      If you are keen, have a look at my build thread. Car is for sale for the right money or straight swap for a F80 M3 LCI.

      Welcome mate.  No point in over thinking it, buying any one of those cars you mentioned is not a smart or logical choice with the availability of many "better" (re price to performance) cars available to you.  The heart wants what the heart wants, buy whatever it leads you too.

      Hey everyone! Im so grateful to be apart of this community and ill do my best to be apart of this. Firstly, i'm not disclosing my real name due to in real life circumstances surrounding my privacy and public image (sorry lol) Secondly, The only thing personal I am willing to share is that I'm from Sydney and a descendant of one of Sydneys largest mortgage firms. I got gifted my first ever car, a 2022 Porsche Cayenne and I love it to death. Ive been driving it for about 5 or 6 months now and honestly Im so grateful for my parents for gifting me this vehicle. However recently I've been working my ass off to afford my second car (which I need help deciding soooooo community help me out please?). Once decided, im planning to try modify it myself. Recent I've been thinking about getting a Skyline, particularly a 25GT or GT-V, yes I know overrated as hell, but I'm also considering a Chaser which I recently came to love. However my dream is to one day own a 180SX (So hard to find clean versions and im not really into importing).  Lastly before I send this off, I want to apologize if I sound tacky or pretentious. I try not to and want to genuinely learn from everyone and anyone. (Im no expert in this area) Thanks for reading!
