Yesterday I picked up a Brilliant Silver 2005 Legacy GT and traded in a 2004 350Z. Now I love my new car but cant seem to find many mods for it. NowI understand that the legacy has the same engine code as the STI and is "detuned" but I would like to get "STI like" horsepower numbers. Are the engine mods for the STI compatible with the legacy (are the engine bays different enough that some items may not fit?)? Next, Are the turbos the same in the legacy and Sti? Also, I noticed the compression, bore and stroke, displacement, etc are identical in both cars ...the legacy puts out 13.5 psi and the Sti 14.5. Question is, what on earth did Subaru do to detune the car by 50 hp and 50 lb/ft torque?? Any info is very much appreciated on current news and products or future items...thanks!

anyone?

Turbo faces up on the legacy and goes thru the intercooler from Passenger side to drivers which is a whole different setup than the STI/WRX/forester etc. Manifold is different because of the intercooler outlet to TB.

FWIW the HP is underrated

Best thing you can do is go back to your dealer and have alook at the differences between an STI and yours. Even a WRX will show what I mean.

Without getting too involved your SOL for now.

It likely has more than 250 at the crank, but never seen one on a dyno so....

Right now the only parts I KNOW fit are the headers. I currently use GP Moto 4-2-1 equal length headers that have the up-pipe integrated to eliminate the up-pipe leaks that can occur on the 2 piece headers. Plus you no longer have the "boxer rumble" which translates to "My header sucks ass because the exhaust pulses get into fights".

Some of the shortrams may also fit, but I don't know of any actualy running said setup.

Thanks for the responses. Hopefully sometime soon performance parts will become avail. for the new Legacy. For now I would be happy with a suspension that didnt float so much during gearshifts.

FWIW it is not the same engine code as the STI
sti =ej257xxxxxx
legacy=EJ255xxxxxx

Still too early dude. Your time and turn will come. So enjoy it while it's still stock. :)

We have an '05 Legacy GT as one of our project cars at my shop and a technician from AVO Japan just flew out last night to work for us for a few weeks. He will be bringing prototype parts for both the USDM STi and USDM Legacy GT, stay tuned for updates, I'll let you know what's in store. FWIW I work at Rallitek so if you want to call us and check feel free.
Cheers,
Joel

hmmm, what made you trade it in for a leg gt ??

just curious :D

well check the mid a

Ej255 is the same thing that the Forester has in it. Shortblock is, from everyone that I have heard from, identical to the 257. Is the Leg Throttle by wire or cable?? If its by wire then check and see if the ecu is the same, see if you can look at it and see if the pintouts are the same and all as the sti. If so you can probably use the sti utec. Also, if you wanted to run WRX derived parts then you would have to either 1. make custom piping for the new intake mani or 2. get a sti intake mani(if throttle by wire) and use it. That would be really cool though to have the first highly modded leg gt.

I needed something practical. The 350Z doesnt do well in the snow and I had my share of problems with it (including tranny probs at 3K miles). The legacy seemed like a good platform to mod considering it was already FI and awd. The 4 drs are nice and I finally have some trunk space. I do miss the tight suspension on the Z, but dont miss the very bouncy ride. The VQ engine was nice but too raspy at high rpn. Also, I installed a Procharger supercharger and always worried about the high compression VQ engine blowing up like many already had. I know I know tuning is very improtant. Overall I miss the look of the Z and the sporty nature, but the materials werent great on the inside. Now I am not yet keen on the look of the Legacy, but its growing on me. As soon as the aftermarket comes around I will be ready to rock and roll.

As far as modding the car, I'm all in. It looks like the internals and turbo can be swapped already. I cant wait to make this car a true sleeper (as if it wasnt one already....a friend completely dissed me when he said, "this car had alot of pickup for a Kia"...and he wasnt kidding, he really thought it was a Kia because he thought the Subaru logo was a Kia logo!!! He doesnt know jack about cars but that one still hurt).

Well, I'm no legacy GT expert, and I'm just pulling this out of my ass:

You could buy a used VF39 and STi intercooler, and mount it up, if it fits. Also get a catless uppipe (if the stock one has a cat) and a turboback exhaust. Then a cobb access port (reflash) for the sti (if it is compatable, I don't know - but it might be). That should put you at around 350 hp.

i think the legacy turbo may actually be in a different position than the STi, so just swapping them both turbo and IC wouldnt quite work but i bet if you have even some creative thinking you could make it work, i also am not positive but i think this is true.

that being said, i am sure its prob just a different uppipe and dp putting it in that position, the upipe can prob be swapped easily to move it unless there is something else in the engine bay, but the dp might be harder to do, if you want to get it to work i suspect you may have to do some fabrication, exhaust wise. then again it may be as easy as swapping in a wrx dp.

i am sure the aftermarket support will come soon, but if all it took was a little pipe repositioning so that you could use all the available wrx/sti aftermarket parts i would do it.

so far you are in uncharted territory so you will have to be the one to do trial and error, but that will be appreciated by other owners when you give the answers:)

just my opinion;)

Ben

Why didn't you get the STi instead if you're not exactly satisfied with the suspension or horsepower of the LGT? I mean the STi is almost as "practical" as the LGT at least compared to the 350Z.

If it's the STi's looks you don't like, well then, it seems easier to change the exterior (de-badge, trunk swap, etc.) than going the other way (engine internals, turbo & suspension).

keepupp,

Check out this site for some more info on the Legacy GT...

http://www.legacysti.com/

All Legacy's, all the time on there. As you have already found, mods are mostly still in development since the car is so new. But, there's still a lot of info on that board about the car in general and what options you may already have.

I didnt go for the STI for a couple reasons. Now i love the car but I wanted more of a sleeper. The legacy offers conservative looks with a pretty loaded interior for much less. I paid invoice for my 05 LGT which came to a tad over 25K....this leaves a huge cash difference of about 8-9K to spend on mods which would take care of the wheels/tires, suspension, brakes, exhaust, etc. Now what I love about the STI is ther fact that it has an adjustible diff., intercooler sprayer, brembos and BBS, etc)

Dude, for another 5K you could have gotten the STi right?
And you can turn the STi into a sleeper by
- debadging (free)
- new trunk lid
- FMIC
- new engine hood sans scoop

Turning the STi into a sleeper seems helluva lot easier & cheaper than turning the LGT into a player, but that's just me. I guess you must love that Legacy interior though. :rolleyes:

The problem that I see with just changing out the turbo and IC is the location of the throttle body in the GT. It is on the bottom of the intake manifold. It's a strange setup.

For extra power switch out the uppipe for a stainless one, and put a stealth back or turbo back exhuast on. All the exhaust looks to be the same as the WRX. That should help out alot. Then wait for someone to come out with some engine management.

I can't imagine people choosing the STi over the Legacy GT. The Impreza platform is just subpar. I sold my WRX and got an Outback 2.5 XT. It didn't take me too long to realize that the WRX was hard to live with- tiny, uncomfortable, etc. So I looked into the Forester XT- glad I didn't get one becaus ethe new Legacy platform is not only good looking, it's powerful and comfortable. I really can't imagine someone buying an STi over a Legacy- the Legacy is underrated and the aftermarket will soon be supporting it here in the US.

wow troll thats gonna make you some friends here.. your an idiot btw

allow me to summarize
#1 NO you cannot use a sti turbo
#2 NO you cannot use a sti intercooler
#3 at the moment you CANNOT swap the turbo at all.. PnP and wheel changes only
#4 investigate the use of a utec
#5 wait for a relfash from cobb or ecutek
#6 look for exaust componets from japan the jdm legacy (realeased a year ago) has the manafold layout but uses a twin scoll - which means it won't bolt on

Thanks for the responses. Hopefully sometime soon performance parts will become avail. for the new Legacy. For now I would be happy with a suspension that didnt float so much during gearshifts.
Somebody was selling a set of the Bilstein struts+springs from a JDM Legacy Spec B in the private for sale classifieds. Take a look as they may still be available.

Please.... please realize that people value different things in their cars... while we will all probobly agree on power, and performance, there are other factors to consider...

"new engine hood sans scoop"

The hood scoop is needed for the proper amount of air to get into the intercooler. Without it, it's detrimental to the turbo.

He did list a Front mount intercooler making the hod scoop cosmetic.

OK so a header fits, which means the turbo is in the same location

the intake side of the turbo is rotated a bit..does this mean we could take a VF34 or whatever and rotate the housing and it would fit?

And then would an Impreza turboback fit? going to a single exhaust instead of dual exhaust should save some weight too

I have a friend who recently bought a G35 coupe and he test drove the 350Z but didn't like it because the interior fealt cheap to him. Funny, I was at my local Nissan stealership the other day getting the oil changed in my wife's '03 Maxima and they wanted me to fill out a credit app to drive a freakin' used 350Z! I told them to go blow. It's not like that car is so exclusive they need to weed out potential buyers. It's not an Acura NSX for fvck sake. I said fine, let it sit on the lot then. They wanted almost as much for a used one as a new one. They had 4 used ones on the lot also. I hate Mossy Nissan. :furious: Glad I didn't buy my wife's car from them. Bastages.

So is even the cat back portion of the exhaust different? I need to go to the dealer and really check one of these out.

Im pretty sure the legacys have dual exhausts.

And Jim the legacy is better for some things and the impreza is better for others. They are different cars made for different purposes.

The legacy has a single exhaust and dual outlets.

By dual outlets you mean the exhaust y's off into 2 mufflers correct?

yes.thats correct.

Here's a bunch of legacy mod info one of our Mid-A folks dug up:

i can't imagine that there are people on this planet that don't realize that different cars are made for different people with different needs. :lol:

and why are we all starting a sti vs legacy gt thread? the dude asked about parts, not what he shoulda bought (in everyone elses opinion)!?!?!

i think (and this is from the brief homework i did on them) that the legacy gt and impreza lineup are just different enough that our parts won't fit without a lot of re-work. the aftermarket will be here soon enough but don't expect it to be as big as the impreza based line. no doubt you will able to get into the 300's, hell if txs puts out a utec that might even do it. :)

has anyone considered that the valvetrains could be different? Cams? etc...
