Default Need help subie newbie.

Hey guys, first off must say love the subie car scene (coming from the ignorant honda game) it's more of a family rather than my cars better then yours . Anyway I have an 05 Rex 2.5 swapped basically my vf48 turbo gave out on me yesterday (did all my research I know it's the turbo). So long story short I'm on of a budget not trying to spend over 600 on the turbo would like to go bigger if possible. Would like to know the best/most reliable way to go. Here's my supporting mods

-Ej257 long block
-DW650cc injectors
-Walboro 255 fuel pump
-3" Perrin bell mouth dp to 3" straight pipe
-Godspeed turbo inlet
(Evap system bypass)
-eBay FMIC and piping and BOV
-K&n typhoon intake
-Grimmspeed EBCS
-Semi deleted TGVs
Thanks in advance guys.

thats not much $ to get a replacement turbo. You could probably get another used VF turbo for <$600 but your not going to get ANY new turbo for that cheap. (I suppose you could get one for that cheap, but i wouldn't touch it with a 10ft pole, much less put it on my suby)

i suggest you start combing through the classifieds section, specificially the engine power and exhaust.

I think Godspeed makes a 20g in that pirce range but as stated above I wouldnt touch it with a 10 foot pole. You may want to consider a lightly used vf 43 until you get some money and go for a larger/quality turbo.

got it stay away from eBay crap. ya get what you pay for guess it goes for turbos too. I could wait and save money to get bigger turbo but it's more then just the turbo correct? (Obv gonna need a new tune if I go bigger) but would I need more supporting/fitting mods? And as far as vf models vf48 is the best of em without having to change the flange? Like I said I'm new to boost any opinion is appreciated

You are pretty much there on supporting mods. The injectors may have to go based on the turbo you select, and yes you will need a new tune if you go larger in the turbo and injectors.

For reference I have a similar setup I.E. hybrid on cosworth 272's, ID1k injectors, walbro 255, DOM3XTR and I am making 351 hp 336 ft lbs on E85. Capable of way more but will need more fuel soon.

Search around on here, talk to a tuner. get a good pairing for your power goals. In the mean time like I said a lightly used replacement turbo could probably be done within your budget.

you cant put the turbo on yourself? i think its a total of 12 nuts/bolts total and a hose clamp for the inlet hose. its pretty easy, especially if you're not pulling the up pipe.

The down pipe has to come off too. There are some good write ups on here for turbo swaps. A tune would help you take advantage of the billet wheel.

Okay guys helpppppppp😭😭 so I replaced the turbo started driving it and the car is having a lot of the same problems( once it starts spooling it cuts off, when I get off the gas it makes a horrible almost suction noises (as if you sucked something up a vacuum) and just doesn't sound good). The old turbo was shot though. So first thing I did to make sure I'm not gonna kill my new turbo is make sure the oil is getting fed to the turbo and it was. Then I checked by the fmic to see if oil was pooled up from the old turbo going and it wasn't. frankly guys I ran out of ideas i was maybe thinking bov I'm not sure how to check that though. I just want my car to run right again any help is appreciated.

Look in your regional forum. Others can recommend local Subaru shops. You need someone to look at your setup. You may have boost leaks and other setup issues. If everything checks out then have your engine tuned.

Check fer boost leaks. Is it slow to spool up? I'd also check the gaskets turbo to dp and turbo to up. Go over everything you did including wastegate lines.

Banjo bolt screen. Blew three turbos on mine before good people here told me to remove the screen. You'll still get oil in your turbo line but it won't be enough

You probably cooked another turbo. Best thing to do right now is take it out and check your banjo bolt. Follow the turbo oil line down where it connects to the head. Take the bolt out and see if there is a screen inside. Take it out and smash it repeatedly and curse it's makers. You'll be ok once it's removed and new turbo is put on. It's not hard to take the turbo out. Should take less then an hour and a six pack for the whole thing.
