Subaru Stars Socal Porting V3 FA

To those who have Socal Porting V3 Port:

1. What are your supporting mods?
2. What type of power are you making?
3. Do you track the car?
4. Would you recommend this for a street car?
5. Was the early power band loss as bad as it looks?

That early powerband loss in the image might actually be intentional on the tune. Trying to keep torque low at low RPM to keep the rods reliable.

That might not be indicative of the turbo itself, but of the tune.

Good thoughts. I have done this myself, I have a track tune to keep everything cool and in one piece. The WTQ is still well above the OEM 350-370 WTQ con-rod capacity. They would have to have built the bottom end to support the 460 WTQ.

It seems to be a common theme across MFGs that a larger turbine wheel doesn't play well with the twinscroll design.

You're always going give up some low end torque and gain top end power with a turbo upgrade. IMO giving up some of that low end and properly managing torque in the tune can help with reliably.

I don't have experience with socal porting...I'm not sure if they do anything to the turbine wheel itself. They say that they port the turbine housing. I don't know if they install a more efficient turbine or clip the blades?

Yes, they install a larger compressor wheel (inducer=52mm, exducer=72mm) and clip the OEM turbine.

I was looking at going for this upgrade next year, along with the KillerB dual EWG header. I'm at 400/400 on e85 with a fully built block that's built to handle 600.
I was weighing the SoCal option or a Tomioka turbo as I'd like to get close to 500whp. So, definitely interested to hear more from other folks.

I intend to go to track days when things open back up, and this is one of the last power upgrades I was looking at. Thanks for starting the thread!

I would recommend either Socal Porting or go with an XR FP Blue with EWG... I hit 511whp with the FP Blue XR w/WMI... (I don't have access to eFuel here so meth must do) .. boosting my custom closed deck block with Pauter X Con rods.. (Prior to FPBlue, I ran a GTX3584RS with custom headers and it netted pretty much the same at a much greater cost.. limited by HPFP cams and finally $$ I decided to spend elsewhere! biggest limiting factor = cash!! LOL

Really curious what your build would produce on some corn. 511 is solid. Im set for tuning on dec 3 and will report what my Flex + socal V3 + EWG header set up produces. Ill be spraying M1 but only 1 jet this time around -- will act more for cooling than supplemental fueling.

I also wonder that.. but to no avail, stations are too far away and lately I've gone bonkers, bought a Ford Transit Van with an Ecoboost 3.5.. gutten it and have a fulltime project to make a "tiny home" on wheels (going full off-grid mode, with solar, kitchen, bathroom, bed, fridge ...... ) I can tow the Rex around now

I have decided to go with the Socal V3 Turbo Port pathway.

UPDATE: Parts are on order, others are on backorder. I will keep everyone updated (w/pics) on the build progress. I am hoping to have everything installed & tuned by February.

FWIW I get protuned on thursday. I can report back with results based on mods + my socal v3.

What other mods do you have besides what is mentioned? Do you have a built block?

Built block (manely conrods, iag pistons i think?) ((I think its basically an iAG stage 2?))
Stock heads -- just refreshed with new seals and what not.
crawford V3 AOS
cobb FF
aquamist meth kit (1 nozzle) (trunk mounted 3 gal tank -- M1)
GS TMIC (Bung by throttle body for meth nozzle)+ charge pipe
GS intake
perrin turbo inlet (for the swagz really)
GS 3 port EBCS
killer B header + 2x 38mm EWG
killer B jpipe
Stock cat-back
killer B oil pick up
Group N trans mount
Perrin motor mounts
cobb AP3 -- protune incoming with mikey botti
AEM oil pressure gauge
socal v3 turbo

Firestone Firehawk indy500 tires + enkie rpf1 (gold for the old school soobie swagz)

For those who want to know, I have been running rotella t4 15w40 with good success changing every 3-4k miles -- will monitor tighter OCI when running E. Shop uses T4 in their FAs for a while and recommends it. Pretty sure its just for the zinc additives in diesle truck oil... whatever. It's working and nothing of concern has manifested itself.

pretty sure that should cover the gist of my set up.

Well how did the day turn out? Pretty stout setup you got there. Very similar to my previous setup minus meth, FF and built block. I was etuned on 93.

Final numbers: 410 whp & 400 wtq

Ran into heat soak issues so we kept it at that but cleaned up across the board. I gotta go back with a thumb drive to grab dyno plots since their computer for the dyno is not connected to internet for exporting files.

Boiz, the car rippps. Feels super smooth on the power and just PULLS.

Why do you think you ran into heat soak issues? Doesn’t the meth spraying into the intercooler help with that? Where are you located? Was the weather warm? Were there fans set up in the dyno?

South florida. Weather wasnt too bad --nice actually. Meth is spraying into the throttle body end tank of the IC, so rest of the IC is cooled by dyno fan and some water we would spray over in between runs to help. Intake temps were fine but hot turbo air heating up the IC seemed to be an issue. TMIC probz i guess. Tune was cleaned up nicely at the power level achieved.

Im thinking front mount would help mitigate heat soak by not sitting ontop of the motor and generally bigger core. But I dont want to mod any more for now at least. Car is fun as is by a lot more than i was used to driving and now im doing big boi adult things like remodeling the house everything cost money boiz...

I’m in NE FL and the above is one of the reasons I went with FMIC.... spent 3 years with TMIC. Loved the responsiveness but heat soak was an issue on hot summer days. I’ll know more this summer but I expect that issue to be solved

How much cooling can an air to air heat exchanger do when you are breathing in 100f air, compressing and heating it up and the trying to cool it with same 100f air flowing over heat exchanger? Its one of the reasons i did not want an fmic, because i think it wont help with that type of heat soak. It also blocks my radiator, impedes flow to it at least. Not to mention other less important nuances like piping in the way and more car modifications to install one. Not worth it imo when you compare pros and cons.

I may be wrong but i would not expect much of a difference on hot summer days. It will be different on cold days when you drive somewhere then park for 30min then get in the car to drive again. It may eliminate the latter type of heat soak. I expect you to tell me how i was wrong if wrong, but i can logically square it cooling 100f+ air with 100f air flowing over it, just dont see it happening. Where i live it gets to 110-120 daily in summer, so no way without water cooling for me to get all my timing in summer.

My other induced car has a separate coolant system cooling the exchanger, now thats a proper solution. No heat ever.
