Looking to put an ez30/EG33 into an xt6

[natext6]

So basically I'm curious as to exactly what steps might be required to bring this idea to fruition. My xt6 is completely stock ATM, except that the air suspension was converted to coil a few years before I obtained it. It is a FT4WD 5spd

 

So what I would like to know is:

Where is a good source to find a used ez30 engine (I live in western canada)

What else will I need to convert? (suspension, transmision? etc.)

 

Also, any tips that people who have succesfully completed this conversion might have for me

And additionally, are there any drawbacks to this conversion? The benefits are obvious

 

Sh*t's about to get fast .......hopefully

I believe the 04 and up got the AVCS w'ever it's a called and a few more ponies.

 

And all-weather package (maybe others?) Outbacks got a limited slip rear diff too IIRC. Don't know what years, but my wife's 03 has one. dig around at cars101.com for features associated with the H6. subaruoutback.org, and NASIOC might be good resources too.

 

this sounds like a wild transplant!

phil - kingbobdole has done it, he's got more info and pic's and information on subaruxt.com about it. he also dropped his into a manual trans as well.

 

there's a few other H6 (EG33) transplants and a few turbo's as well into XT6's.

 

getting a wrecked vehicle is a nice way to do a swap.

You'll need the engine, engine management, and the exhaust header.

 

Then from there, you have 2 or 3 choices on how to install it.

 

1) Redrill your flywheel and use an adapter plate EJ to EA style, with you're existing trans, and trans mounts, etc....(most "bolt on", simple method)

 

2) since your XT6 trans is single range FT4wd , split your existing FT4wd case, and then transfer the guts into a standard EJ 5spd case from 90-98 model. Then use standard EJ flywheel and clutch choices(best offroad option)

 

3) drop in a complete EJ tranny (AWD) and modify crossmember, shifter, and driveline to fit (best performance option)

Which is a better swap? EG33 or the ez30?

 

I'm also interested in putting a turbo into it, which engine is the easiest to put a turbo onto? (also, any recommendations on turbo make/model/year/etc?)

 

I've heard that the ez30 doesn't need an adapter plate, and that you only need to alter the drive-shaft lengh to apply it?

 

I REALLY would love to keep the push-button hi-low 4wd (if that makes any sense ) is there any way to keep it as-is? I love the way it drives! not that AWD wouldn't be great as well :-p

pro's and cons to either.

 

the EG33 is an awesome motor, very reliable and few issues.

 

if you're really doing a turbo then i would look into which is the best for turbo applications since that's a high demand use of it.

Uh......pushbutton? Hi/Lo?

 

Though you said it was a Fulltime 4WD, which in an XT6 should be single range?

[natext6]

I'm probably just mis-describing it. While running normally, the car distributes 90% of the torque to the front wheels, and 10% to the rear, but there's a button in my center console that changes that to 50/50....or at least that's what I was told....

XT6 has a FT4WD transmission. they do not have hi-lo, and it isn't "pushbutton" in the normal sense of the word. XT6 is full time 4WD the button is to lock the center differential.

 

pushbutton transmissions typically refer to the PT4WD, the part time 4WD transmissions that are in FWD until you push the button (which is often, or always) on the stick shift itself.

[natext6]

Thanks for the explanation! Now I feel like a moron But back to my question, is there any way to preserve the lockable differential, while applying a new engine?

 

On another note, I'm going to have a look at an SVX in the PnP calgary, what parts would I need to take from it for this conversion, should the mileage be acceptable, and the engine in working order.

See my first post.

 

Option 1 or 2 would both leave you with the FT4wd, with lockable center.

 

BTW....You do no you shouldn't use the Diff lock on pavement. It basically locks you in 4wd, allowing no slip in the center diff.

[natext6]

I only ever use it while off of pavement, only when losing traction on snow covered roads and such.

 

The first option sounds best to me, as I'm not planning on doing much offroading if any at all.

 

Do you know of anywhere where I might be able to procure diagrams that would help with the flywheel drilling and adapter plate creation? (I'm assuming I have to make/drill this myself)

 

Will I need a new radiator? and will I need to extend my engine bay at all to accomodate either the EZ30 or EG33?

i would say post this thread on subaruxt.com i have done an eg33 swap along with two other regulars on that board

this thread in particular should be helpful

I don't know anthig about the swap but I do know if your going to turbo it go with a remote mount turbo( inplace of the muffler) because the xt6 has a very tight engine bay already and with a swap like that I can only imagine it getting tighter.
