Default VF52 SoCal ported upgrade or New Arashi Turbo?

Was looking at getting my vf52 turbo upgraded and ported and polished one to get rid of boost creep and 2 want a little power punch.
But at stage 2 and stage 3 Iím in the price point of a new arashi turbo.

Hard to say. Never heard of Arashi turbo but doing a quick search on the forum, ppl are happy with the,m for the price. Now how long will that last is a mystery. I think in one of the reviews guy had his for 2 years or so and was still running ok.

What do you mean by "getting my vf52 upgraded"? Do you mean change out the fins and port and polish or just port and polish?

Who will be doing the VF upgrade? If it is a well known turbo shop then i would go with the upgraded VF. What is your turbo budget? Don't forget about the install and tune cost.

SoCal porting https://socalporting.com/subaru-turbo-upgrade/. Didnít really want to splurge on a turbo but saw arashi was close to the same price as getting the vf52 upgraded

Socal Porting has a great reputation and works with reliable turbos (VF). If it were my money, I'd go with them them over a lesser known new turbo company. Turbos have a rough life, I don't take chances on those kinds of parts. I skimp on parts like catbacks, or the engine dogbone. But if your turbo goes, it takes your motor with it. Not worth the experiment in my opinion.

Socal Porting and also (who I went with) Hillcountry Performance have great reputations for rebuilding and upgrading VF turbos.

I had my VF37 twin scroll upgraded with a center ball bearing cartridge, ported/polished, turbine housing coated, and compressor housing powder coated. They do 16, 18, and 20g upgrades as well. Turn around time was good.

I had a great experience with Socal Porting on my VF48. My Tuner was also impressed by the turbo as even with the Stage 1 upgrade, we ran out of fuel injector on my 05 FXT which he didn't expect. All that being said, I am sitting on a 1.5XTR awaiting install about 1.5 years post upgrade just because i've already grown used to it and wanting more.

If I wanted more low rpm boost/less lag go with stage 2 with evo3 16g style wheel or 20g?

16g will be better spool but it will drop at higher RPMs.

So would the 20g wheel be a littler slower than vf52 wheel? Should be quicker than a normal 20g turbo tho right?

You need to read up on how turbos work. There are two things that a person looks at when picking a turbo. How fast it will spool to full boost and how long will it hold that hp in the higher RPMS. There is no turbo that does both. Smaller turbos will spool up and get to full boost quicker but will not hold that power at higher rpms. Larger turbos will take longer to spool and get to full boost but will hold the power all the way to redline. So it is a fine balance that you have to take in consideration. If the wheel is larger, there is more mass to move. So it will take longer for it to spin up. But if the housings where air flows through can only push so much, no matter how larger the wheel is, it will choke on its own narrow passages and the large wheel will be useless. That's where porting comes into play. Don't forget about your exhaust side too.

I ran a Stage 3 VF52 from SoCal Porting for about 1.5 years as well. My original intent was to go with the DOM 1.5 XT-R but I was curious to give a stock framed turbo a shot.

To the OP, here is my .02 cents....

If you are on a built engine or plan to be then save a little more and go with a DOM 1.5 XT-R. from the get go. My little experiment meant paying for tuning twice which is not cheap when you are on a Flex Fuel setup.

If you are staying with a stock block then my vote would be to go with an upgraded VF52 from SoCal Porting.

in my opinion a 16g is a waste or money its too much like a vf. if you are going to upgrade do a upgrade. get at least a 20g or get a 3067 gtx from atp.

agree with gc8. either go with a 18g or 20g. But at that cost you might aswel save up a couple extra hundred bucks and get a band name 20g and be done with it.

Iím really just leaning towards SoCal ported or hill country pnp and upgraded wheel. Donít know what wheel tho. If I get something like 16g that will move the curve to the left and could I run into the possibility of have to much torque quickly on a stock wrx tranny?

How was stage 3? I assume it was a lot like turbo parts Canadaís vf20g.
Vf quick spool but quicker and carried more longer?

Have you called SoCal? They're good to talk to, and they spend all the time you need on the phone with you asking all kinds of questions. After talking to them, I came away with the impression that they're real and honest, I wouldn't hesitate to have them do any work for me.

When my turbo seals blew I had good luck with these guys:
https://xsboostturbochargers.com/col...31770491551809

I bought a reman V52 with billet compressor wheel.

I'm running a stock block WRX at 325hp/350tq at 20psi. It's a good unit for the street.

Its your money, but like others have already said, upgrading to a 16g is not worth the money in my book. Lots of WRX owners have used the 18g on the 5 spd tranny with no issues. The 5 spd is weaker then the 6 spd, yes, but its not made out of glass. If you get supporting tranny mods and not shift like a retard, your tranny will be fine.

Actually wait, do you have a 2.0 or a 2.5 eng? If you have a 2.5 then i would recommend the 18g, if a 2.0 then a big 16g would be fun. What is your plan for the car? on a 2.0L small 16g for street fun, light to light, an big 16g for highway.

But again, in the end its your money and do what you want. Just don't put in a 16g and expect to do great at a drag strip. Now if you want to do autox then the 16g might be your pick. I like my power higher in RPMs.

I have a 08 wrx which is 2.5. Talking to Eric at torque performance he says arashis arenít bad. He said td05 20g will get me to 350. I gotta guy saying get the td06sl2 20g as it more linear and not come on crazy strong with might be too much for the 5spd.
I just want a DD turbo that doesnít have too much lag but doesnít fall off so hard.
Iíve read some people believe that arashi 20g is the same as the Cobb just rebranded
