for advice, you posted in the wrong section.

that siad, if you are aiming for 380whp, what fuel will you be running?

 

[Karlot]

also, i noticed you didnt say you have any injectors. you will need these. so far as which. let me know what fuel you plan on running, which will tell me what turbo to suggest for 380whp, and then i can more easily say what injectors you'll need

 

[robautuori636]

93oct no injectors yet

 

[Karlot]

to make that power, you'll need injectors.

for that goal, i'd personally go with a blouch dom 1.5xtr with the 10cm hotside option. i dont think you can get the 3' inlet unless you delete tgv's, which you can not tune for on cobb with the greenspeed update. so far as injectors, i'd suggest id1050s.

if you dont already have it, a 3 port ebcs would be something i would add. and above all, pickup a killer b oil pickup/baffle combo, a quality AOS (killer b or IAG), and a cylinder 4 cooling mod.

IHI VF48 Hi Flow stock replacement with 10% extra boost, bolts right in place of stock. same manufacturer as the stock turbo. just an idea. the picture/chart claims up to 390

Blouch says none in stock place order to secure your space in line . Fock. What about precision turbo?. If I go with something like a 6266 will there be sufficient lag?

Want something with good spool that pulls top end but reliable

Just a heads up, you're going to want to be realistic about your expectations. Anything large enough to get you to 400whp is going to introduce some form of lag. It may be so minimal that you don't notice it. The DOM 1.5XT-R @Karlot was mentioning is basically the go-to. If I wasn't an auto-x junkie that would be where I'm heading. You can also experiment with Precision's bolt-on upgraded turbo. MotoIQ tested it in the past, and recently and the results were good on paper.
That said, you should talk directly to someone who can calibrate or tune your car in about specific setups. @yamahaSHO is solid and can help you out. Again, you need to be realistic, and realize that when you're talking this power level on 93, you're starting to get close to the limit of what's reliable on the stock block.

Has anybody heard of a guy named luigi from Olympic motorsports he tuned my car a local mechanic said beware of him not sure why but he's close to where I live

Why would you put a turbo good for 700 whp on car you aren't looking to break 400 whp with? You're going to have so much lag the car won't be much fun on the street until you hit 5000 rpms. If you can't find a dom 1.5 then get a 20g and call it a day.

IAG has just released complaint tgv's that function like stock yet flow better than their v2 tgv deletes. No idea the cost though.

Thank u thsts what I was worried a about

My reccomendation is also a 1.5XTR. But it will only get you to 380 if fully supported. Add at least an ELH. Will a tuner provide you a dyno sheet that shows 380 regardless? Plenty of people have em . . .

Also the 1.5s I'm familiar with are external waste-gate so you'd need that and an up-pipe, and something to deal with noise. Mine is routed back in to the down-pipe. The EWG may not get you more power, but it will help the tuner (especially if you have a cat) and allow the car to respond better - Oh add an EBC.

ok, so none are in stock, i had them rebuild my 20G, aka not in stock, and it took them like 2.5 weeks. i'm sure it wont be that long to wait. a 6266 will NOT be stock location, if you are going to go rotated, i actually ahve a different suggestion on what turbo to run, rotated, go either efr7163, or garrett gtx3071r gen2. but keep in mind both will cost quite a bit more than a dom 1.5 or a 20g. the 6266 will likely add approx 2500rpm worth of lag when compared to a stock turbo, meaning you'd be able to make full boost in the 4800-5k rpm range, giving you 2k rpm of actual power band. will you be able to make a high peak whp with this, yes, will it be fun, no, it wont.

^agreed here. OP you need to do more research if you are going from wanting 380whp on a stock location turbo and suddenly jumping to a 6266 which is a 700whp capable massive turbo that is certainly NOT stock location. precision is a quality brand, and does have a bolt on turbo for the subaru, but it's nowhere near the size of the 6266, which, unless you are either drag racing or chasing numbers just because you want to say you make xxxwhp, i would NOT suggest the 6266 to anyone. it's simply too big for our cars.

^exactly that. if you cant find a 1.5, a blouch 20g xtr will get you in the 350whp range, which,if you have not driven these cars at that power level, it's wayyyy more fun than you'd think. i have a 20g xtr that is fully supported with bolt ons, i made 377whp on pump gas (after new tune that added equal length headers and a built block). my oem header power number was 343whp i think. still it was fun.

IAG has just released complaint tgv's that function like stock yet flow better than their v2 tgv deletes. No idea the cost though.

yes, but to fit the 3' inlet, you need the motors on the tgv's deleted, meaning even with their new compliant ones, the inlet would still contact the tgv motor/connector and would not fit.

A well supported 1.5/20G is night and day from any stock turbo. The numbers are almost meaning less. Though many are inacurrate in magnitude the full dyno has meaning and you need to have experience to know what to expect from viewing one that is accurate.
