Looking to upgrade turbo. Options?

So I'm in the process of replacing my head gaskets. Found out that the turbo is no good either. So I can either but a rebuild kit for the turbo but I was thinking of upgrading it altogether while it's all apart, without having to do too much else to the motor. I don't mind upgrading if it's not super expensive. Just looking for options to get some power,

Any ideas? Good aftermarket turbo kits for not a ton of money?

Re: Looking to upgrade turbo. Options?

Try finding a good vf39 or a 16G but keep in mind that in order to get the additional power a bigger turbo will generate you must go to a higher flow rate fuel pump (walbro 255 for example) and higher capacity fuel injectors (STi pink or 06-07 blue). Then you also need to get the ecu programed for said changes (get a tune).

Re: Looking to upgrade turbo. Options?

Re: Looking to upgrade turbo. Options?

Trouble is a turbo usually isn't just a turbo.  It's a turbo, injectors, fuel pump, tune, maybe intake/intercooler/exhaust too  smile
A good start would be telling us if you have a 2.0L or a 2.5L engine!

Assuming turbo back exhaust and solid tune you should see something 290-310WHP and 320-340 WTQ with somewhat slower spool, but stronger mid and upper range.

Re: Looking to upgrade turbo. Options?

Gonna go with an ej205, I can get for $1000. And possibly the vf39 turbo. Which if I'm gathering I would need to upgrade the fuel pump, injectors, and get a tune. Am I correct in this?

Yep, that's the minimum. I would get rid of the TGVs, replace the turbo inlet, used STI intercooler and replace the radiator while you've got it out.

Bigger turbo is not necessarily easy power. Bigger turbo = more stress on the drive train. Like mentioned above you'd need to upgrade to bigger injectors, bigger intercooler, protune, and fuel pump. Hardly an easy, cheap, or reliable option. If your car was stock before a down pipe and a tune are probably a far better bet if you plan to daily it. From there I'd move to some suspension upgrades like swaybars, endlinks, and coilovers then before upgrading the turbo brakes, clutch, and intercooler.


06' Silver Aero 5MT - Cobb Turboback, Stage II  93 octane tune, ST coilovers (KW Variant1s), Cobb short shifter, 22mm front and 24mm rear whiteline sways and endlinks, engine rebuild (Manley forged rods and pistons)
White 2015 WRX - Whiteline rear swaybar, Perrin brass shifter bushing, Cobb J pipe, Cobb Accessport, custom buzzard damage

Re: Looking to upgrade turbo. Options?

I'd suggest a used STI turbo like a VF39 like others have mentioned is a good cheap upgrade.  You can get a good one for like $400.

Oh, I have my stock 92x aero turbo laying around somewhere.  It is in good shape.  I haven't used in for 7 years now.  You can have it...say for $50?  That covers shipping, and the hassle of shipping it.  Honestly if you don't have a lot of money for modding it, that is the cheapest and safest way to go.

When I broke my rear diff, I was having thoughts about R180s, and STI 6-speed swaps.  Eventually I just spent $75 and got another used R160 off of craigs list.  Worked fine.
