Alternative powered XT /6's collection

Postby Fury on Sun Mar 28, 2010 7:10 pm

This is a thread to document all "re powered" XT6's and XT's
A repower is not intended only for performance, but reliability as well.
This thread is intended for engine repowers, not transmissions and associated other equipment. Perhaps similar threads for other things could be appropriate if this works well.

The suggestion is to document , in one place, all engine re power modifications - Listing clearly :
(Template to copy and paste - highlight area to copy, keys ctrl + C to copy, then ctrl + V to paste)

Written in a format so that not only for the benefit of the reader ( for entertainment and relaxation ) but as a jump of point to do future modifications.

We all read from time to time, how people want to do modifications by re powering their XTs and we get a number of similar threads, most with a lot of really great info being duplicated. In a thread like this, is in my opinion, a great place to start. If a thread pops up, we can post a link to here.

Posters... If your info is incomplete, or no pics etc, a new posting such as "edited info", or "new updated info or pics added" could be appropriate and this post deleted after a few days or so - just letting people know , but not intended as a perminant reference to the edit.

Perhaps moderators can reposition postings , so similar engines are grouped together, or 6's and XT's
also, perhaps the removal of posts such as "awsome car" and "un necessary posts" after a suitable period ( perhaps on a previous page) so people can still comment, but after a while, as they just take up space, could be deleted (no malice to the poster and no offense etc) but would make searching and reading easier for a person looking to "re power"

I have been messaged many times regarding conversion details, and I am quite happy to answer questions etc, as I am sure other owners of such converted vehicles are also happy to do. However, I would also like to add that if you are considering modding your XT / 6 , repowering to a "different from original" power plant, that it is not an easy thing to do and takes time, experience and money, to make it successful. Regardless of the success stories you will see below, all the modifications are real achievements of the highest standard, that have overcome sometimes enormous obsticles and difficulties that would make a lot of qualified mechanics turn in their graves. I personally know what you have been through and salute you for your expertise, your patience and endurance. I guess what I am saying is that when considering such a conversion, if you havent done this sort of thing before, you will need help.
Pulling out the old engine and placing the new into the engine bay, is the easiest part of a precision procedure., getting it all connected up and running like it was from factory is the real trick and not something to be entered into lightly.


If you have contributing thoughts to this thread, please feel free to jump in.

Engine size / capacity : EJ20T

Installation difficulties : lol, to be edited when I have time
Performance specs and dyno results if applicable : 204Kw ( dyno) 274 Hp

Original installation just after the first test drive.

Looks a bit better than this now - well sorta..

Owner / Forum username : Phil, The Kingbobdole
Country : USA

XT6 or XT : 1989 XT-6 AX-7 FWD
Engine type and size / capacity : EZ30D 3.0 liter
Engine year : 2003
Original car it was from : VDC Legacy outback
Engine modifications : Intake? Ghetto cooling system. High flow exhaust. Replaced valve cover gaskets and spark plugs.
ECU : Stock legacy
Drivetrain and ratios : 04-05 STi 6 speed. Super racelight ACT flywheel with stock STi clutch

Installation difficulties : Wiring was huge, It takes me, Mr. wire, about 6 hours to get an OBD1 EJ harness together and running from a "full car harness". This thing took me OVER 20 hours of work. VERY complex and I even left some stuff off of it. Since my car was front wheel drive, I had to locate an AWD transmission mount... Lastly... someone moved/pilfered/I lost/rocket started the car while it was on top'd one of my FSMs while doing the build... Never found it. :( Also, the throttle cable and cooling system were interesting.. ohh and since it has an auto belt tensioner, that took some doing as well. The first time I started it, the flywheel touched the engine crossmember when I accelerated... Itmadeallotasparks :lol: The stock header really won't fit at all...

Performance specs and dyno results if applicable:
200 WHP 215 Ft/Lbs WTQ
Image

Legalities for registration purposes : Cats? I don't even need those... I live in a no test area. Car is OBD2 compliant. :wink:

Pros : THROTTLE RESPONSE! It's like my right foot is attached to a giant french war machine of old and dropping the hammer launches me all the way to Britain. It would tear the old bald tires off it in most gears... while rolling... at speed... ask Austin. Relatedly you can scare children with the size of the throttle body. It's a new engine, most of the seals are not worn out yet. Parts available... since it's a current gen engine... there are also some plug and play managements for it. Easy fit, lots of extra under hood room. It's a new engine, mine had 75k on it when I installed it and now has just over 85k... no where near time for heavy maintenance. New engines have OBD2 which is nice for troubleshooting. Fairly light weight as well. Timing chain instead of belt, according to some they take a long ass time to wear out. Gets about the same MPG as the old motor did, but with lots more hooning. Did I mention it's new and reliable? Unlearned people look at it and go "That's the XT motor?.... looks just like the Legacy motor!' :lol:

Cons : Dude! She takes PREMIUM!! Still a fairly pricey swap even now. I was thinking about doing the EG33 like Huck, and was even offered an engine and wiring for $250... I still ended up on the more expensive road. Also, it's got that stupid dual upper radiator thingy. Damn motor mounts are EXPENSIVE!

Rusty, Have you got a thread to your rear mount radiator? if not, MAKE one and post the link in your above post.. I think modifications - particularly associated to repowers would be good from this thread.


This post should self destruct in a few days... :lol:

Never weighed it, but guessed it to be about 2,900 pound.....about the same as a Stock XT6....but all the AC stuff, and Air Suspension stuff was gutted
