400hp?

[InspectoRob]

I recently saw some parts on ebay that were removed from a "legacy e-tune". I tried doing a search and very little came up except a used car dealer in GBritain that had a wagon (01 I think) and in the description it said that it was twin turbo with 400hp! Does anyone know anything else about these? Are they really that powerful and are they common in other countries? Are the parts compatible?

We don't get alot of the really cool cars here. The JDM twin turbo engines stock run 280bhp. But that's because of the old non-written rule that no cars should come out with more than 280hp. There's always rumors that this engine and that engine stock can handle this and that, like an EJ22T can handle 500hp, or a stock EJ20T can handle 500hp, or that the EJ257 (semi closed deck turbo 2.5L) can only handle 400hp internally... ect.

 

The thing to do would be to get a JDM twin turbo 2.2L. The 2.2L is the best engine for reliability every designed *from* subaru. (I'm not talking about TWE or Cobbs fully closed deck modified 2.5L engines) I would rather build the CRAP out of a 2.2L (money being no option) than a EJ257 merely for the fact that the 2.5L is semi-closed deck, and is also overbored. (the more you bore out, the less cylinder wall space you get... and the less reliable too)

 

So grab a JDM 2.2L twin turbo motor. Put on some VF34 turbos, new exhaust, some insane injectors, chip it up, cams, ect. and you'd be waaay able to get 400hp. Check out www.nasioc.com . they have posts all the time of people dynoing their STis and stuff. (500whp!)

 

yeah, it's possible to get 400hp. How much money do you have? And yeah, twin turbo EJ motors do exist.

That is excellent info. although I do not have endless money to do any of those modifications. Fun to think about though!

 

The impression I had from the "e-tune" cars was that they were the european release of the legacy GT, but one step further without going aftermarket. (similar to our impreza group( L, WRX and STI). They were selling a stock exhaust manifold that was set up for the twin turbos, etc. Do we have any British people on this board that might know if I am correct?

[InspectoRob]

I just found another site with a little more info. and it shows the Legacy GTB etune II Touring Wagon has 280hp. stock. (twin turbo 2.0 liter).I imagine that the one I saw for sale with a claimed 400hp was modified.

I still would like to know if parts are compatible with any of the US cars. Anyone?

same here,i'd love to put twin turbo on my legacy.

yeah, except for maybe the fact that there's no such thing as a JDM twin-turbo 2.2l. The only turbo charged JDM 2.2 is in the 22b, and it's a single turbo. It's a lot easier to find a USDM EJ22t out of a turbo legacy, as it's pretty much the same block. The 22b block is the phase 2 EJ22t block, and basically, the only difference is that the phase 1 has oil squirters. All the TT JDM engines were 2.0.

 

Want to learn about the EJ22t and what it's capable of? Read this.

 

Here's a little excerpt from the thread:

4. The T.Legacy engine failure experiment I refer to invloved my attempt to find out what the limits of the engine were. It started with a T.Leg engine with 150,000 miles from the junkyard. First, I ran it for weeks at 27-30 psi. Second, I over-revved it to 11,000 rpm twice, by shifting from 2nd gear redlined, to first (by the way, this shift can only be done with a dogbox). After having no failures, I finally took it to Second Creek Raceway. This track is a 1.7 mile circuit track, with hills, chicanes, all kinds of turns, and so forth. I drove the piss out of it for 20 laps straight (over twenty minutes straight), shifting at 9000 rpm, heating the hell out of it, and pummeling it with tons of boost. Eventually, I spun the number 2 rod bearing. After tearing down the engine, inspection of the engine revealed that other than the bearing, the rest of the engine was in perfect shape. Furthermore, the failed rod bearing was more than likely caused by damage sustained from the 11000 rpm incidents.

then how come i have seen ej22tt ( thats right twin turbo) engines on ebay?

[mattocs]

Oh man...i'd love to have a twin turbo in my Outback...people would laugh at me when I wanted to race...then i'd hand them their rump roast

Glad someone else knows that there was (is) no twin turbo 2.2. Also, be aware, not all EJ20 Twin Turbo create 280hp, the early ones were less then that. Getting 400hp out of an EJ20 is not hard to do, but doing so also reduces the reliability of the engine because doing so creates more heat and heat is the killer of all engines.

ooooh, and one more thing about TT engines. They won't fit in a LHD car. Well, unless you moved like the steering linkage and the brake booster I think. Of course, there are a few RHD postal wagon Legacies out there.

Dr RX, I thought you had a 2.2l twin turbo longblock for sale a while ago. I was musing about TT's and saw your ad on you page. I'm probably wrong again though.

Old boy you're quoting has it wrong... overrevving will cause piston-valve contact if it's going to destroy anything. I'm pretty sure that the rod bearing let go due to culmulative damage from detonation, and the rest of the bearings would show it if you know what to look for. The top bearing halfs should have interesting wear patterns.

 

Just a fine point I wanted to pick at, the EJ's are still wonderful engines.
