TD06 20g?

Just wondering if this will fit on my 08 wrx as a direct replacement? Also I dont think the intercooler to the turbo is a direct flange bolt on so how would I bolt the intercooler on? Any more info on the turbo would be great. Thanks

1) No, its not the same turbo layout as your car.
2) Why are you looking at a 20G? Are you planning on upgrading or just want to a new turbo to replace a broken one?
3) You will need some add ons to make the turbo you choose to run vs your stock set-up. At the very least you should get a Process West TMIC or FMIC, TBE, and a fuel pump. But, I'd say injectors and a 3 port bcs would be added onto that list as my bare min. Might as well get the most out of the turbo if you are going to put it on.

exactly....point proven...research! research!! research!!!!

Just ### a 20G is a nice big turbo doesn't exactly mean that its the right fit for you either, its a sweet upgrade dont get me wrong but you would maybe benefit from many other turbo options(or maybe not even a turbo swap at all). It just really depends what your trying to do in the long run i suppose.

If you just jump into something you may be doing more bad than good.
if I had to guess, I would say your probably not quite ready yet anyway...no disrespect, but thats an upgrade you should graduate too. . . .But like I stated earlier keep doing homework...GL

It'll work, it just requires some modification to the set-up to run it. You can't just slap it on and walk away. Biggest reason is this.



See how different the layout is? The 2008 WRX and up layout is on the left and the 2002-2007 WRX/2004 and up STI layout is on the right.
Like, I said. You can use the 20G turbo. It just requires some extra work and changes.

I already got a turbo back exhaust, I am planning on buying a front mount to go along with the turbo. After I install them I am gonna get a bigger fuel pump and injectors which should do the trick.

At least if you get an FMIC you can run any turbo layout you want so yes the 20g will fit.

Just know if you push the 20g you will be at the limits of the stock block and you could pop it, and most likely will after some time.

As long as you're aware of the risks go for it.

Just to clear things up and since your mod list isn't filled out here's what you need:

Must Haves:
Fuel Pump (walbro 255 or deatschwerks 300)
Injectors (min 750's for pump, min 1000's for E85)
Turbo
FMIC or larger aftermarket TMIC
Aftermarket Intake that works with whatever FMIC you get (consider KSTech 73mm big MAF, you'll probably max a stock diameter MAF quickly)
TBE (you already have)
Pro-tune for this setup

Optional:
EWG Setup (since the turbo is out it's an easier job)
3-port EBCS such as GrimmSpeed (Not 100% necessary but I would do it)
Turbo Inlet (may want to while the turbo is out)
PnP stock exhaust mani OR aftermarket headers
Another Tune for all the above if done at a different time

Oh and expect to replace your clutch within a year.

That is a bare minimum right there.

A 3 port bcs, intake, turbo inlet, EWG, and whatever headers or PnP exhaust manifold option you choose would be all optional. But, a lot of those are highly recommended upgrades. You probably would be pushing the stock engine to its limits and the stock clutch will probably die out after some hard thrashings.

You can do your project at whatever pace you want. But, it will require a protune and some people save up all the parts they want installed in batches. That way they are not running back to get a protune each time they put on one part. Good Luck with the upgrades.

Brakes, suspension, engine mounts, definitely clutch, good tires (not all seasons).

I already got the parts that are required but I am looking at a set of headers. I know I need the tune but the best shop around is 8 hrs away in minneapolis sio i will have to take the car to them to get work on it done.
