02 WRX vs 05 Legacy GT

[phobiarg]

Tonight was by far the closest race Ive ever had, I raced a stock 2005 Legacy GT with my 02 WRX with a TBE. We went from a dig all the way to top end, literally a all out drag until we both hit top speed. I got him off the launch by a half car and he kept me there until 3rd when I missed it and he jumpped ahead by atleast 2 cars before I got it sorted out. It stayed this way until ~110 when I started to gain again, by 130 we were side by side again and we both let off. I know I know those speeds are way too fast for public roads but no one else was around us and how often do you get to race a LGT against a WRX?

i've never raced one.

fine by me.

nice kill...er....death....eh

[John M]

LGTs are quite fun...

[DTR rex]

Never really had a chance to run one. I played with one a while back when I was making stage2 power and I was a bit too much for him to handle. I envy his interior though

[Flat 4]

There's a real quick LGT out by me and I got smoked.

I have an 06 Legacy GT as well as an 04 WRX stage 4. My legacy is very comparable to my wrx at stage 2. The wrx is currently at stage 4 but has a bad tune, so it still probably wouldnt fare very well.

The legacy is refined, quiet, rides nice, actually has real paint and has every amenity. The wrx has its boy-racer looks and low cost, so I dont mind nearly as much modding the sh*t out of it.

The GT has potential to be an animal, as it has the STi engine which is essentially detuned and very easily upgraded.

Sorry for bringing this thread back from the dead, but is that true? Does the LGT have the same engine as the STi? I thought it was something more similar to the 2.5L WRX engine with a slightly bigger turbo.

i'm pretty sure your right. yes it has a 2.5 like the sti but i'm fairly certain it's a differnt block.

# 2.5 L, DOHC, turbocharged and intercooled four-cylinder engines are available in North American market GT models, beginning in 2005. This engine shares many parts with other versions of the Impreza WRX STi, Forester XT and Baja Turbo, as well as the Outback XT which are available only in the North American market.

from :http://www.motortrend.com/cars/2005/...ons/index.html

- Turbo compressor
- 2,457 cc 2.5 liters horizontal 4 front engine with 99.5 mm bore, 79 mm stroke, 8.2 compression ratio, double overhead cam, variable valve timing/camshaft and four valves per cylinder
- Premium unleaded fuel
- Fuel economy EPA highway (mpg): 25 and EPA city (mpg): 19
- Multi-point injection fuel system
- 16.9 gallon main premium unleaded fuel tank
- Power: 186 kW , 250 HP SAE @ 6,000 rpm; 250 ft lb , 339 Nm @ 3,600 rpm

Compare those numbers - namely bore, stroke, and compression ... to this pages description of the EVO vs STI : http://www.motortrend.com/roadtests/...ecs_price.html

Looks to me like they may in fact be the same engine. Might be a simple matter of adjusting the tune and changing the I/H/E to match or surpass.

For 05-06 models, heads, cams, block are identical. Differences are with the turbo (STi-VF39, LGT-VF40...smaller), catted UP on the LGT, plastic intake manifold on the LGT, smaller but more efficient (for it's size) TMIC on the LGT, slightly smaller diameter exhaust piping on the LGT but with dual exhaust ends (twice the cost I might add ). STi has stronger R180 rear vs LGT R160, and the STi's torque sensing diffs front and rear as well as an active electronic center diff are vastly superior to the LGT front open diff, rear viscous, center viscous.

Of course, the suspensions are different, but believe it our not, pretty much the same mounting points. And last but not least, the STi 6 speed is much stronger but LGT gearing is better (IMHO) and the STi has the god-almightly whoa peddle due to the incredible Brembos. The LGT brakes...quite simply suck.

and there you go folks. you da man.


ok did i just say you da man.

And the LGT's unique turbo-to-TMIC connection makes it much harder (expensive) to upgrade the turbo and/or the IC. To top it off, the throttle body mounts on the intake not in the center but at the rear drivers side of the manifold. This makes it ideal for flipping for a FMIC install but it makes it impossible to upgrade using WRX-spec TMICs.

The turbo connects to the IC with a flange instead of a coupler, further complicating aftermarket parts. Right now the only LGT-specific TMIC upgrade is $700 and I won't pay nearly that much.

The first company that makes an upgraded TMIC that fits a WRX-style turbo and the LGT's intake manifold will make a killing, especially if they bundle it with say a VF34 or VF39.

Oh, and since this thread was created, I've since gone Stage 2. It's even more fun now

heh....I know some things about what I am interested in, so thanks . Now...no clue for other manufacturers tech specs (unless you count Mopar as I've also got a 70 Cuda 340 6-pack, 727 slapstick parked away for my kid's college fund... )

Too bad its not a 440 6 pack. I saw one get bid up to $225,000 this weekend in AC and still din't come close to selling. Just rediculous.

I figure I've got about a decade before I sell it. I'm hoping by then it is somwhere around the same price. The 340 6 pack was a fairly rare build...and mine is 100% stock with 46K miles on it. Prisine in and out. Never been restored or repaired and it appears these type of vehicles are gaining ground over the concourse-ready 100K+ frame off restoration sales due to their ability to actually be driven on roads withought imediately loosing significant value. Only time will tell, but I'm confident I'll be able to pay for a least the 1st year of school for each kid. After that, they are no longer "kids" and will have to learn about working. After all...thats what parents are for, the broad objective "catch and release" program
