Am yet to experience the ball bearing effect. For some reason after I took off my td04 don't seem to want anything else but a ball bearing turbo. I will be getting a steam speed 20g too for my 07 wrx. I bought one from them great fitment but sold it after my 2.0 motor spun a bearing during a road tune.

There is a similar thread to this about steam speed turbo's performance and results. 75% of the people in there with the steam speed turbo say they are underperforming versus the competition. If you go through the proven power bragging I'm sure you'll find it. But if you're happy that's all that matters right?

If I could afford a GTX line turbo I would definitely be getting one. The GTX 3584 RS is a monster of a turbo. I know the fella in south Florida who did some testing for steamspeed. He wasn't too impressed and went to a precision.

I definitely need something reliable. My 07 don't need to make over 400whp since my 92x build needs to break the 500whp mark. I also need a turbo that has potential to perform good at all times spools good and keeps going. The gtx I s a pricy thing but definitely a contender and ball bearing is a must. Be waiting too on holiday discounts see which vendor I can combine coupons lol! One thing about me I never pay full price for anything I do my home work.

FWIW I remember Killer b talking about the built in EWG versions and commented that they aren't as efficient (lots of turbulence) as regular stock flange turbos. They suggested the traditional ewg in the uppipe is going to be more beneficial.

I have not come across that but again I wasn't looking. I can stick with the uppipe ewg set up for this car. The gtx one just seemed differently unique compared to regular set ups. And I like that edge. Do yu know of turbine housings for a stock location turbo that do t even have the opening of the iwg Eliminating the need to shut it with a bracket or welding?

Maybe it's just cheaper to shut it with a bracket.

What they said for stock location.
Although Borg Warner Airwerks turbos have what you describe (rotated).

Here it is.

BW SXE S300 T4. 80 something lb/min with a spool valve. Bought the turbo over a year ago donít remember the specs anymore lol

We stopped around 20psi because I was getting some spark blowout and the pump couldnít keep up in the higher RPM. Nice and conservative. I also am only using a MBC on the spool valve and we just eyeballed it (went full tight and then just loosened I like half way; nothing scientific) for now since it was ****ing cold and I was having those couple of issues. Iím going to sort those things out and come back in spring for more power and then tune the spool valve.


My buddyís on a 7cm FP green on his sti and heís making the same power/torque as I am at 4K and my power keeps going where his stays around 400whp.


Iím overall extremely happy with the setup and Iím glad I went this way. Iíll check back in a few months when I tune the valve further and add more power.

What's the lower pair of curves in that chart?
Old turbo (what kind?), or pump gas, or...?

Lower is pump gas, less boost

Yes I bought it from AGP.
I have a close deck block, o ringed, Manley I beam rods and Manley ext. turbo tuff 9.8:1 compression pistons. (99.75 bore)
04 sti heads with BC 272 cams and springs ret.
Perrin big tube headers with their rotated t3 up pipe.
Tvg del with the stock intake mani
Aem 3.5 bar map
Fid 2000cc injectors with a relay wired in tank w450 pump
-8an feed to the rails -6an return
And will be on e85

I was hoping to get close to 600whp even with taking this to 33lbs if I had to, but iam stating to think Iíll be falling short with this turbo.

I have the 252, somewhat wished i went with the 257. I also have the .82 a/r t3 open AGP housing. The lag is real, 30 psi around 5,000 in 3rd. Fortunately AGP housing are pretty cheap so i might try and swap it out for a .63 to see it changes anything

Yea Iíve heard you can gain only about 30 hp on the big end with the .82 housing. Iam glad I went with the .63 t3 on my 257 sxe but I was simply hoping for a higher output of the 257 and not loosing that spool time. Iíll have to just see what my numbers look like. I know itís kinda of a trade off but I always think spool is more usable power.

Look at some pte5858 graphs. Should be in that area but you should have more top end because 2.5L like big turbines. The 257SXE is basically a journal bearing EFR7670.

You can here when i hit peak boost when ewg starts screamin. This is a 2.2 with stock S20 heads. Pretty basic. I actually dont know the boost it was at. I had it tuned to 28psi the day before in 80 degrees. Dyno day on the way there it was 60ish and started over boosting and hitting boost cut. I did a couple road flashes to reduce WGDC and still over boosting, eventually i just cut WGDC way down to get it under boost cut. So this is anywhere from 24 to 28psi.

My torque drops like a biotch, Dont know if its boost related or too conservative with timing





I havent gotten to tune it at all yet this year, since i pulled the motor out of the forester, and built this for it. Im waiting on my PA Title & Registration
