I'm running a GS crosspipe with manifold's I ported myself. Essentially the same setup without coating, but I'm using heatshields.

One of my injector o-rings was on its way out with a slight leak, and totally obliterated itself this morning, so tuning is on hold for the moment. While it's under the knife I'm going to change the plugs to OE heat range copper v-grooves, I was getting a little blowout at high rpm with the E85.

Very nice. That graph would seem to suggest that there's more to be had from 4000-5500 RPM as well.

I figure I'll post my build. Just wondering what numbers you guys think I'll be able to hit with my setup. I still have to figure out who tuning it?

07 WRX:
Built 2.5 EJ257
CP 99.5 8.2-1 CR pistons
Eagle rods
ACL race series bearings
Pistons have been side skirt coated as well as domes coated

05 STI heads
STI cams
Invidia tbe non-resonated
Tial 38mm vband grimmspeed ewg setup
HTA68
TGV deletes
DW750's
Perrin 2.4 inlet and afta maf
k&n typhoon SRI
STI top mount IC

running a killer b oil pickup tube, should be dropping the motor in soon, I have done a complete transformation of my WRX it now has 04 sti speed and r180 and this would be the third motor.

^^first motor popped from the tune (too much boost and timing)

Second motor spun a crank bearing due to either over revving it or wristpin clip popping out of its hole.

Im not sure the exact numbers, my buddy was open source tuning it at the time and had flashed a updated XPT map on to my ecu. a few WOT pulls later and I pop the ringlands on two pistons. cylinders 2,4 to be exact. live and learn

ohh yeah! you could feel it pull timing, and then it smelled like oil was burning and then it popped a CEL. we pulled it when we got off the HWY and p0304 misfire on 4. I'm averaging 25k per motor. I currently have 50K on the odometer. so not too bad, considering I beat the piss out of my car. My tranny held up the whole time, but this last motor I decided to pull that and go to a 6 speed.

Agreed, that's a shoddy way of ending an argument.

Yeah, I knew this turbo would be a little monster when cranked with good fuel..

For what it is, a tweaked 16g, it flat out rocks. For a street daily driver, that is a very nice fat area under the curve.. I like.. Which is why I ordered one up.. Should do nicely in my e85 burning wagon..

I just tuned one of these on a Forrester XT 2.5L and wow was this thing quick. Only running 18 PSI at the moment as he is on stock fuel system/Stock IC but car is wicked quick and spool up is like stock. Definately making 300 WHP based on AF ratios and inj duty cycles.

No, but he is correct. In the cold every single 7 cm housing I have played with creeped.

My hta68 which has about a 10psi spring in it (or something close to that) will creep to a little over 16 psi in the cold. Now, seeing as that is lower then my boost target, it doesn't really matter.

Still not quite understanding why people think it is not a good choice for the 2.5ltr. It spools like a 39 and makes 20g power. Creep is minimal. Its a great turbo.

If you can drive, high 11's/low 12's are more than doable with supporting mods (at sea level).

Goint Green on the 2.5ltr with just 93 pump, IMHO, sucks. It will make 10-15 more peak, but you will loose the insta-boost of the 68.

My Hta68 (10psi spring) ran 10psi solid, cold or not. Seeing how you mention boost targets, were you running a bcs at the time?

Absolutely wrong, creep isn't exclusive to a small housing, it's the combo of a small housing with a small wastegate port that really does it. From my experience tuning this turbo, this is not the case. Talk about spewing misinformation.
