Yes, to my knowledge I can. I'd gut the power windows at the same time and leave them stationary (could always switch it back when I got back home. It will only have the drivers seat during the competition.

As you stated, you just purchased this car, and you obviously just joined this forum...so maybe you should actually listen to those of us whom have been modifying these cars for quite a while...
Your example of the Impreza is irrelevant...as it was with a different engine and in a lighter chassis...
In some cases, our cars our as much as 500lbs heavier than an early GC Impreza

Yes...my car does have full interior...but I still don't think that taking out 100lbs of interior stuff will get you into the 13s

Depending upon how long you stay around here, you will find that we are not like NASIOC or any other forums.
And I dont think Nick sharing his opinion can hardly be considered flaming.
Anyways... Have you considered a head swap? Its a lot more work... But if drag times are you goal that may be a solid option.
And a vf-39 ought to be able to get you there. Assuming you have fuel, intake, IC and other basic supporting mods.
The thing with the td04 is that its not that much of an upgrade from the stupid stock little vf-11.
Just a friendly FYI

Yeah, I don't think Nick meant to flame you. It's just that many of us have found that results didn't always match our hopes with the simple kinds of modifications you're talking about. If the car you're referring to is an automatic Impreza 2.5RS, you should remember that it was lighter, had more displacement, had a higher compression ratio, had better-flowing heads, and had a more drag-suited transmission than your car.
That said, I'll second the suggestion of a head swap and a VF39. It is a lot of work, you might find it'll get you where you're trying to go. And if you have to pay someone to help, labor isn't counted in the challenge budget, right?
Another thing that could get you a lot further is switching to the stock engine management from an early overseas model that made a lot more power. Our stock engine management isn't especially aggressive or precise when you start pushing past stock power levels.
Another thought would be switching to a transmission with a higher final drive ratio, and/or switching to tires with a lower overall diameter.

I work for Subaru, the GC cars are on the 90-94 legacy chassis. Outside of the 1.8 liter enigine models, the weights are with in roughly 200 lbs.
His car had a full interior. I have the heads and engine to build his same engine, a Phase II bottom end with Phase I heads. But the 2.2t is a much stronger bottom end.
I've owned eight subaru's including two prior 90-94 models. I may be new to this forum, but I'm not a newbie.
That being said thanks for the input. Sorry, I am used to NASIOC and I-Club forums, been a member since back when they were one in the same. I don't spend much time there these days. Prefer LegacyGT forum.

I have a pair of 2.5 DOHC heads and another 2.5 DOHC engine lying around, but the space between the larger heads and smaller block would concern me running higher pressure.
The TD04 was cheap with low miles, so that's what I'm going with for now. I don't need a drag monster, I'm just trying to get into the 13's, which should put me in the top ten for this low buck competition. If I'm not making enough power, I'll cut the fat.

check out the thread "ej25 SOHC heads vs ej25 DOHC" in the engine forum...
there is some info on there regarding head swaps... what works... whats extra work...
You could consider an ej20g head and mani swap. Thats less complicated than an ej25 head swap.

For the record, It was a 97 or 98 base 2.2 liter with an engine swap, running a Forester auto tranny and rear end (4.44 gears) it was a 60ft beast. Though it actually ran larger diameter tires than stock. It had a TD04 and WRX TMIC with a RS hood. He used a solenoid out of a nitrous kit to dump in fuel under boost and an Sti fuel pump.

That sounds... um... interesting... and kinda complicated...
AND an auto with 4.44 would be quite the drag setup...
we have a 3.90... Hmmm... Maybe just a wee bit different?!?!?!?!?

I think that's pretty awesome. Seems actually very simple. Aside from part swapping, there wasn't a whole lot of complexity.

Oh i didnt mean non-awesome...
But it would be a large undertaking for me... thats all.

I'd have to buy those, I have the 2.5 heads and manifold.
I don't have the experience with modifying the 2.2T as I’ve had with the 2.5T and other swaps, that’s why I’m here.
What have people obtained with the stock block and heads?
Anyone have success porting and polishing?
I’d assume messing with the stock cams is not a worth while undertaking?
Labor, if paid for, does count, but I have access to more than one Subaru dealership, so labor is not a factor.

He ran wide high tires, nearly outback profile, but wider. You could run smaller tires with the 3.90's and have a similar effect. My 2005 LGT has 3.90’s as well, and larger 235/45/17’s. It goes pretty good.
It really was a pretty simple set-up that worked really well.
I'm not saying it is the same. But the TD04 was a capable pump in that system. I don't want to go too large with the turbo and deal with a lot of lag.

You are correct:
3.272 Auto (VTD)
4.111 Manual
The Na cars were:
4.111 Auto
3.90 Manual
The Outback XT's had 4.444 with the manual.

Kool... that makes sense.
I'm not trying to hijack... But can you swap a LGT tranny into a 1st gen? I mean without all the axles and rear diff but only the actual transmission?

I have the data dvd on the 06 and it does say 4.111 for the LGT, I could have sworn my '05 had 3.90's, I'll have to crawl under there and check.
You could swap the tranny and rear diff, but you'd probably have to mate the inside LGT CV's with your axles.
The trans itself has basically been around since the 80’s, though the newer ones are stronger, they’re the same design. The LGT is supposed to have the strongest 5spd, it’s listed as reinforced, while the WRX is not.

However, take a look at the gear ratios from the '06 model Year:
---------------2.5i-----LGT
1ST GEAR: 3.454 3.166
2ND GEAR: 2.062 1.882
3RD GEAR: 1.448 1.296
4TH GEAR: 1.088 0.972
5TH GEAR: 0.780 0.738
The LGT has talller gears, so it is not as big of a difference as would 1st appear.

I think your 13 second goal is possible.
If you have DOHC heads slap them on, they should help get you to your goal a little easier.
I sort of see where some of this comes from as some SSs with upgraded turbos ran in the high 14-15sec range in the past.
I have a TD04 on my full weight (heavy...) 4eat SS now - it pulls pretty good & responds very well on a DOHC 2.0l (its on a EJ20G) .
My plans were to put a 16G on the car straight away, but the TD04 @ 16psi steady (18psi .5 second spike) made my want to see what could be squeezed out of the car with the little turbo (alky injected of course).
Track opens in March I'll see what my car does then.
If it is slower than I think it is, a ported 16g, a VF23, & a Turbonetics T3/T4e are all waiting to get put on a car....
Mission will be accomplished for me either way as I'll know how the car runs with the Baby turbo.
Traskw (& olny traskw) - let me know if you could use a EJ20G ECU/Wiring harness or EJ20k intake manifold complete.

Is your alky injection your only form of "intercooling"?

In 1st the 2.5i's engine has to rotate 13.47 times to rotate the wheels once, the LGT 13.015.
The LGT has the taller overall ratios even though it has 4.111's vs. the 2.5i's 3.90's.

Na, I have a FMIC + alky injection on the SS.
I had good luck/gains with alky on my Impreza so I'm hooked on it now.
The SS & our "Welfare-Racing" 9.97s 1/4 mile drag car both have alky injection.

I was considering alky, which system (brand) are you using? I was actually considering using it if I went with nitrous, to handle all the heat. If I could set it up for use only when I was on the bottle, I could tune the car with just the turbo for autocross, the bottle and alky for drag. Though I would have to sacrifice elsewhere to stay under budget going that route.
