ski racks help especially if you have the deflector on the front of they it helps channel the air up and away

You couldn't be any more backwards. Ski racks add a fair chunk to the frontal area. More frontal area = more drag. Generally speaking, someone with a ski rack mounted on their rails will get up to 4mpg LESS than those who dont.

they you probable dont have it set up correct. I know this cause ive seen the wind tunnel tests if you have the install done right it allows for better are flow over the top of the vechicle much like a big rig wind deflector. now if you ski rack has room for the air to get around it then yes your getting yes mpg because your creating more drag

Dude....just dont.

And for the record, big rigs use air deflectors over the cabin in order to smooth out the sudden transition from the roof of the cabin to the taller roof of the trailer. They do not add any frontal area. Key term here: frontal area. Please dont make me go all engineering nerd here. I'm asking nicely.

Go bigger turbo. This way the turbo doesn't spool up so quick. Running my TD04L on my JDM 6spd sucks on the hiway because the moment you give it some throttle the turbo rolls into boost.

The VF43 wont be terrible, but you may find yourself boosting undesirably high when going uphill.

20G or FP Green should do the trick.

This is a very interesting thread but I only read the first page.

I just lost second gear in my EG33 swapped 97 Legacy Outback with 140,000 on the original tranny and 1000 on the new engine so it destroyed it pretty quick. Engine puts out about 230 ft.lbs I think.

So I have to do something about this, probably get it rebuilt rather than throwing in another high mileage box. Ratios seem fine to me except if 5th was way bigger that would help getting to events. It seems to have the 4.111 LSD in it. stock center viscous and open front. I do have a brand new KAAZ diff sat on the shelf. Should I throw that in? Car is used for autocross, rallycross and track days. If I'm going to rebuild it what should I change while I'm in there and can I get a much bigger 5th gear out of this job?

Not looking to spend a fortune either.

so Im i need a little advice, I finally got my WRX back on the road after an 04 STI 6speed swap. I love how the car just wants to get up and go threw the lower gears but up top when im in over drive (6th gear) @ 80mph the drone from the exhaust reminds me of my old 5speed when i was cruising in 4th gear before hitting 5th.
I was wondering could I do a hybrid set up where i keep my 1-4 gears stock and have my 5th and 6th gears a little longer? or should i look for a 07 and up sti gear set?

Shipped it off to Thompson Racing Fabrication for a tranny rebuild and KAAZ lsd after breaking 2nd gear.



Still would like a taller fifth when all is done. Easy to swap in or do you need a whole gearset? How tall a fifth can one get?

Is the JDM STi 6 Speed the same a USDM STI in the way that is compatible with USDM engines upgrading to a 6 Speed? or do I need something different using JDM 6 Speed? Can I use USDM diff, linkage, crossmember etc..?

as long as you have the matching final drive everything bolts up the same.

Ok, at present this is hypothetical, so please don't be cruel in responding.

I want to build a second gen LegacyGT for autocrossing. This is a project car for fun because like to tinker with cars, however, I'm no cone carving guru, so I'm not planning something that will get me to solo nationals. I've been autocrossing for many years, off an on, so I know the general idea, but I've never run a can with a swapped engine, so I'm kinda starting from scratch.

What I'd LIKE to install in the car is one of the following: EJ22(t) hybrid (EJ205 heads), EJ205, or a EJ255/57. Of those, I think the closed deck block with WRX heads is the most interesting, followed by the 55/57. It's not that I want to build something that will take 30psi of boost, but I don't want to worry about block strength ever, should I decide to get crazy someday. I'm a Cali guy, so it would be nice to have a smog legal car, however, if that's even remotely difficult, I"ll trailer the car's to events.

That said, the REAL point of my post is about gearboxes. I want to install I decently close ratio gear box with a 3.90 or 4.11 FD. 5 Speed is perfectly ok, as I rarely get passed 3rd gear with my '06 LGT when autoXing. My concern is about gearbox strength.

I know the USDM '02-'05 MY gearboxes had some design flaws the manifested themselves if the power levels got above stock levels. Is there a particular JDM box that would be ideal for what I'd like to do? I would really like to avoid things like DCCD. In other words, what OE gearbox has the best case strength that might also have ratios that would be helpful to me?

I know the search feature is my friend, and I used it quite a bit before I decided to post, but I never zero'd in on what I would like to know.

Thanks in advance

Sounds to me like you want a JDM STi 6-speed. Short ratios, all the beastly strength of the 6-speed, and available with a non-DCCD center diff.
