2005 LGT Ltd Wagon 6sp 340WHP Build

Recommended Posts

After spending over 4 years building a 1998 Legacy GT Ltd wagon with STi swap only to have it taken from me by a 19 year old girl running a red light at 50MPH the day after I got the car finished, I decided to upgrade a bit and picked up this 2005 Legacy GT Limited wagon with 5 speed manual transmission from another LGT.com member, BoostWagon who was an excellent seller and all around nice guy.

 

Here's a shot of my 98 swapped wagon

Here's a description of the car from the previous owner:

 

The engine is dead stock except for a K&N filter in the stock air box. The turbo was rebuilt at 73,000 miles, the timing belt was replaced at that time. The heads were rebuilt at 83,000 miles, the engine has been trouble free for the last 50,000 miles.

 

The clutch was replaced at about 115,000 with a WRX clutch, WRX flywheel, and tranquil snout kit (TSK). New battery this past summer.

 

The suspension has been modified but not slammed, with Perrin front and rear

sways (22 mm rear), Kartboy end links, and Koni adj shocks (shocks at about

103,000 miles). Handles great, not punishing unless you crank the shocks up.

New front lower control arm bushings.

 

Front brakes redone at about 98,000 miles with new calipers, new rotors, and Hawk HPS pads.

 

Interior is excellent, heated front seats, HVAC, and secondary controls all work

fine. Rubber floor mats and rear cargo tray. Jazzy Engineering iPod kit.

My goal for this car is to have it reliably putting down about 340 AWHP and have all issues sorted out. I want to have this be my DD for the next 3 or 4 years. I'm planning on selling my 2006 Nissan 350Z to buy a 1968 Camaro so the Legacy is going to be doing double duty as my DD and my sports car.

 

After my 98 was totaled, I stripped it for parts and kept a bunch of stuff that I'm going to use on the 05. The parts include:

V7 STi 6sp transmission

R160 Mechanical Limited Slip Rear Differential

Exedy Street Organic Disc Clutch

Exedy Heavy Duty Pressure Plate (feels way too heavy. wish I used the regular one) - ended up switching to a regular Exedy STi pressure plate and love the pedal feel

STi Clutch Master Cylinder & Slave w/braided line

STi trans mount

STi Shifter w/K4rtBoy Busings

Megan Racing Engine Mounts

Grimmspeed Electronic Boost Control Solenoid

'04 STi BBS Goldies and set of silver STi BBS for the winter tires

Invidia Up-Pipe

Helix Crossover Pipe

Brian Crower Valve Springs & Retainers

 

Some other parts I've collected that'll also go into the build:

StopTech front 4 Piston Calipers with ceramic pads

DBA Front Rotors

Continental ExtremeContact DWS 225/45/17 Tires

Cobb Heat Shield

HID Kit - never installed this

Auto Driveshaft from 4EAT for 6sp swap

SPT Exhaust

 

Parts I've recently bought:

K&N Typhoon CAI

Gimmick Silicone Turbo Inlet Pipe

ARP Head Studs

Invidia catless Downpipe

DW 1000cc Side Feed Injectors - tuners didn't want to work with these injectors so I did a top feed conversion with ID 1000cc injectors

All CV Boots

Rack Boots

All Wheel Bearings

New 09+ EJ257

BNR 18G Turbo - wastegate actuator from BNR wouldn't hold boost so I upgraded to TurboSmart unit

11mm Oil Pump

EJ257 Oil Cooler

AVCS Oil Control Valves

Oil Pan

Gasket Set

All Rubber Hoses

 

Parts I still need to buy:

JDM Double Din Radio Kit

Window Tints - DONE!

Front Grill

Fender Repair - Found a replacement fender in SWP

Grimmspeed TMIC Kit - LOVE this piece. Wrapped it with some heat reflective gold tape and it looks great and is VERY effective. My tuner took temps and remarked about how it wasn't heat soaking

WeatherTech Floor Mats

Front Lip

Since I got the car, I had to replace the injectors to get rid of a rough idle and misfire CEL. Other than that, all I did was change the oil and put some winter rims and tires on it.

 

It's been an absolute pleasure to drive so far. I've put about 6,000 miles on it in 4 months. Looking forward to more!

Will the v7 6 speed swap into the 05? I was under the impression you needed v8+. Not sure where I heard that though. Hope I'm wrong. Look forward to the build!

 

I don't know anyone else that's done it but I don't see any reason why it shouldn't. The cases are the same size. The only difference in the V7 6sp is lack of DCCD, which I don't want anyway, and the closer ratio 5th and 6th gears. I'm going to lose an MPG or two but I really don't care. After driving this gearbox in my 98, I LOVED it. Can't wait to get it swapped into my 05.

I saw your part out threads on other forums. I was wondering what you got to replace the 98. Looking forward to your progress.

 

Thanks man! I'm going to have a few part out threads starting on this forum too. I'm moving away from the WRXs and into the Legacy GTs now. I picked up another 05 Legacy GT Ltd 5sp wagon that I'm fixing up a few things on and reselling, picked up a 05 Legacy GT sedan with some nice mods that I'll be poaching for my build and then parting out the rest, also picking up another 05 Legacy GT auto with a rod knock that I'll be fixing and reselling.

 

I'm really gonna get to know these cars!

Looking forward to your build Sir, good luck. I'm also looking into doing a EJ257 build. My motor has 90k and all cylinders are good with the exception of cyl 2. It's starting to go, need new piston rings. So I'm thinking of just either swapping a 257 or buying a built 257 short block, then finding a solid Sti long block and doing the internals then swapping everything over from mine. Any thoughts or recommendations? Suspension and brakes have been fully swapped and about every bolt on installed. I got my hands on a BNR 20g 11 blade that I'm holding off on installing until I build the motor. Looking for around 420whp.

Even though I read the first line and my heart dropped through the floor for you, I'm looking forward to seeing the build on the new LGT. It's super pretty. Love the LGT in white.

Personally, I'm a fan of using a stock OEM Subaru built short block because you know what you're getting. I've heard so many horror stories of built short blocks going bad very quickly. Unfortunately, you're capped at about 350whp with an OEM 257 block if you want to run it safely. If your car is a daily driver that you need to rely on, I'd suggest this route. If your car is more of a toy, weekend driver, track car, autocross car, then go for a built block and crank up the boost!

 

If you need a short block for the foundation of a build, I may have one for sale. I'm picking up that 2005 Legacy GT sedan later today with a lightly spun bearing. The short block only has 2800 miles on it and I'd bet that the crank and block halves are still good. I need to pull it all apart to inspect everything first though.

This is my exact car and I just picked it up a few weeks ago. Just bought the BNR 18G today! mine has 136k on orig turbo/clutch so I am not driving it much until i get the turbo and all supporting mods on. I'm hoping to avoid a block rebuild for a year or two, but am interested in going 6 spd when the tranny goes. I haven't found any threads on that swap but maybe I missed them.

 

I'm open to any suggestions you have, this is my first subie.

Wow, you're a brave man slapping an 18G on a motor with 136k and original clutch! Best of luck with it. I absolutely love mine.

 

Here's how to do the 6sp swap: http://legacygt.com/forums/showthread.php/6mt-master-swap-thread-107137.html

There is a fine line between brave and stupid. I only meant that 135k orig is my starting point. I get a compression test next week to decide what needs be done to support the new turbo. Hopefully #'s are good and they can drop in forged pistons, rings etc. already purchased: Cobb cai, 740cc injectors, fast motors tmic, boost solenoid, invidia catless up/down, killer b oil feed, exedy stage 1 clutch, Cobb AP3, full tune by IAG perf,bc coils, white line adj sways, kartboy end links, kartboy ss/bushings.

 

What am I missing? Bov? Oil/tranny cooler? New tranny/motor mounts?

 

Thx!

:mad:My motor just started knocking the other day. Looks like I'll be doing the new motor and build sooner than I had planned.

 

Just ordered 4 new hubs, all new axle boots, rack boots, 6sp shifter arms so I can use an STi shifter, 6sp axle seals and sun dials.

 

Next I have to cough up about $3k for the ej257 short block, gaskets, BNR 18G and CNT down pipe. Ouch!

How did you catch the knock?

^I started noticing a very light noise when I would rev past 3200 RPM. It also did it a bit on startup when it was warm until it got oil pressure. It has sat for about a month and I just started it the other day to move it to where it will sit until the motor gets pulled and it didn't knock when started cold. I guess the oil was thicker or something.

 

Anyway, I ordered my parts today. Put in the order for:

EJ257 short block

BNR 18G Turbo

IPT Oil Line Filter

Engine Gasket Set

Gates Racing Timing Belt, idlers and water pump kit

NGK Iridium one step colder plugs

AVCS Oil Control Solenoid Valves

Oil pump

Oil pan

Oil cooler

All vacuum hoses

All coolant hoses

PCV valve assemble

DW1000cc Injectors

CNT catted downpipe

 

Now I'm broke.
