Default Question: Legacy 2.2 Turbo

Hi guys,

first i wanna introduce myself. My name is Florian, i'm 27 years old, am from Karlsruhe, Germany, and own a Subaru Legacy 2.0 Turbo 4WD Sedan.

As far as i know, the model i have was never available in the US, but you have a 2.2 Turbo, that never was available in Europe.

What are the specs to your model? It got more cylinder capacity but less power. What kind of turbo is build in it? What boost?

The EDM model has a 2.0 Turbo. The turbo is normally a VF12, boost @ 0,8bar, ~12psi, and the compression is 8.0 : 1.

What about the USDM model? Where are the differences?

Well, the stock ratings are 160hp and 180 tq. The engine came with a VF11 Turbo, and no stock intercooler. I don't know what the boost is off hand.

Best place to ask this question would be bbs.legacycentral.org

As Mark pointed out, the bbs at Legacy Central is the best place to go for info.

He also pointed out the power and torque ratings, turbo model and lack of intercooler. Boost was ~8.7 PSI stock.

The big differences are the intercooler, larger capacity and the SOHC-per-head configuration in the USDM models versus the DOHC setup in the rest of the world (and probably yours)

Hi Florian,
As has been mentioned, there are pretty significant differences between the two cars. For comparison purposes, our vf11 turbo is very similar to the smaller vf10 turbo fitted to your automatic transmission legacies. And then we don't get an intercooler. And we get heads that flow about 75-80% as much as your DOHC heads.

I am going to guess that what are really wondering is if an Ej22T engine would be a good option to replace your engine. It would not. but the block would be. It's become very common here in the states to match Ej20 DOHC heads to the EJ22T block for more displacement while getting the added strength of the fully closed deck block. As such, there is now a premium on these blocks. Blocks now go for $600-1000 each in need of a rebuild. I remember when you could get them for $150 all day long as complete engines. They are a great option, but either those that have them in their cars (like I do in my '91 Legacy turbo) hold onto them or they sell them for lots of money. If you have found one and are contemplating buying it, I say go for it...

Thanks a lot for the replies.

In fact, it's just curiosity. I'd never have a chance to get such changes accepted by our Technical Inspection Authority.

180tq, what measure is it? Something like pound per feet?
The EDM 2.0 Turbo has 260Nm (Newtonmeter)
Even i'm not sure if the HP in the US and Europe are the same. Do you use kw (kilowatt) as well?

So the Turbo setup seems to be like a softturbo. Guess it's pretty dependable. No lag, smooth acceleration.
The VF12 is similar to the TD05, big housing, huge lag, you need to pass 3500 revs to gain some boost, but then you'll have some fun!

We don't use those units (Nm and kw) but it would be 244 Nm and 119 kw respectively.

Thanks a lot.

The US HP is not quite the same as the german PS (HP).

160HP = 119Kw = 162PS

1 hp (horsepower) 1 0,745700 1,01387 1 kW (Kilowatt) 1,34102 1 1,35962 1 PS (Pferdestärke) 0,986320 0,735499 1
hp is the same as bhp?

That's correct. In Japan they rate them in PS as well. Here in the states we usually use the two interchangeably. For example, people around here always say that the 97-98 Ej20K had 280hp, when it really had 276hp=280ps...
