THIS IS SOLD... THANKS FOR LOOKING

I bought a version 8 EJ207 engine and went for a larger than stock turbo (Full Race EFR6758 kit). I had done an oil pan swap on my EJ205 to run Perrin headers, so now I have all these leftover pieces that happen to make the perfect 2.0L twinscroll upgrade kit.

I'm including:

From the ver8 engine:
stock version 8 twinscroll turbo with all hardlines still attached (except oil feed line, which won't fit any USDM Subarus.)
stock version 8 twinscroll manifold and uppipe (never unbolted uppipe from manifold.)
stock version 8 twinscroll downpipe
all OEM heatshielding, brackets, nuts and bolts for the above pieces. There are 3 brackets and 4 heat shields. This thing is FULLY heat shielded.
stock version 8 tubing from turbo to boost control solenoid (including restrictor pill)
Twin scroll oil cooler (bends and hoses are slightly different from stock oil cooler, so you need to replace it)
STi pink injectors.
Used gaskets
stock version 8 turbo oil drain line (looks to be the same as an EJ205 drain line) with spring clips.

Parts from my EJ205, I don't know exact mileage of these parts, ~30k ish on the oil pan swap, probably 50-70k on the walbro. My engine did NOT spin a bearing, so the pan is in great shape:
06+ 2.5L oil pan to fit the twinscroll headers
oil baffle needed to fit the oil pan
dip stick
dip stick tube
Walbro fuel pump

Brand new:
Oil pickup tube to fit the 2.5L oil pan.

I am asking $1500 firm picked up for the setup. This is roughly equivalent to vf39 performance, but twinscroll.

The full OEM heatshielding makes this very stealthy for anyone concerned about that, as well as keeping the valve cover gaskets and passenger side axle & joints protected from the turbo heat. It looks OEM and makes great power even through the stock cat due to the bellmouth design of the twinscroll downpipe. This is a really awesome street setup for an 2 liter.

As far as I know (but I will not guarantee) there's only a few additional pieces needed:
1) You will need an exhaust pipe fabbed that's a few inches long, as the JDM downpipe is a tad shorter than USDM. This pipe will fit between the end of the downpipe and the beginning of the USDM catback section. It's only like 6 inches or less.

2) It's very likely the stock turbo oil feed line doesn't reach this turbo's oil feed hole. I do not know for sure that you will need one, but I think it's very likely that you'll need an aftermarket WRX stainless braided oil line. I am including the bolt for the banjo on the turbo, which appears to be M10. I have the version 8 hard oil line, but it's useless, since it bolts to an AVCS line that's different than the USDM AVCS lines. Obviously you'll need new crush washers for the banjos.

3) You need gaskets for head to manifold. You "should" get new gaskets for turbo to uppipe and downpipe, but I've included the old ones if you want to try to get them to seal. Injector o-rings look in good shape.

4) You will need a tune, if you want me to tune it for you after install, I will do so via open source for an additional $200... only for the purchaser.

Here are the pictures of what I have for sale. Again, asking $1500 firm picked up:




only items included that are not pictured are the dipstick and tube, because I forgot to put them in the picture.

Thanks for looking. PM if interested,

This might be a stupid question, but what kind of performance gains would one see on a ej20? What is the benefit of the twin scroll vs a 16G?

 

I never installed this so I can only talk about the theoreticals:

1) Twinscroll is equal length by definition. So it gives all of the benefits of equal length headers with all that good heat shielding to keep things warm. I'm sure it's not stainless steel, but it is tubular like aftermarket headers.

2) twin scroll will give better spool up when you're over the boost threshold (boost re-builds quicker after a shift, for example.)

3) off-boost torque is better on equal length headers and twinscroll takes that a step further. So cruising around is a little more pleasant.

Overall power and spool won't be too far off a vf39 / small 16g, but there's not a lot of concrete data out there with this setup on an EJ205. If you already have a turbo this size, I don't think it's worth considering. For someone that hasn't done much of anything to their WRX and considering a turbo upgrade, this is a great size turbo for the EJ205 and they are going to want an uppipe and downpipe, pump, and injectors anyway, this gets them all that and a proper equal length header setup that's better than the Perrin header setup I ran. The EJ207 begs for more turbo, with AVCS giving so much better spool-up, but the EJ205, not so much. I think this is near the ideal street setup for an 2.0L WRX.

Interested in selling just the 2.5 oil pan set up?

 

Will a USDM-fitment downpipe, stock or otherwise, fit the turbo?

 

Flange is totally different, you can see the gasket in the box in the third picture that shows the flange outline.

There is also less need to go with an aftermarket DP, the stock twinscroll DP is a bellmouth design. Going aftermarket 3" and cat delete will help, but I don't think it'll do a ton at the HP level of the stock turbo.

I think IAperformance sells a flange that with a good welder can be used to adapt a USDM DP to the twinscroll, but like I said, I'm not sure how worth it that is.
You can also get full cast bellmouths that can be welded onto a USDM pipe. Cut off the bellmouth and get a welder to put the twinscroll bellmouth on there.
So there are ways to adapt a USDM DP, but they aren't easy.

 

Copy that. If nothing else the DP will let me pass smog/po po popping the hood (yet to happen, but as is I'm pretty stock), which is a nice convenience, while still making a load of power. Going E85 too, so all the faster (and cleaner).
