Thanks for the info, that helps a lot. I just missed buying a 5MT STi transmission, and am still trying to figure out what to do. Are you running the DCCD as well?

What's your opinion of the drop in 12kfg and 20kfg center diff options for the 5MT transmissions?

Thanks, great video! The resolution isn't enough for me to tell what the boost gauge is supposed to be showing. Plus, I've never owned a turbo, so it wouldn't have made a difference.

How do you you have your car setup, i.e. transmission, engine config, etc?

Ouch, shipping from Portland is $1,000

Thanks! Its an automatic, but I've got the parts to do a manual 5MT swap. The price is right, though.

I'm thinking of getting a turbo Legacy for rallyx, predicated on bumping the torque/HP with some mods. (My current rallyx car has a 2.5L engine in it.) On paper the mod'd 2.2T should have better torque and HP than the 2.5L, but at what cost in lag? Are people just putting on giant turbos and waiting...

Sorry, my '93 Sedan doesn't have a passenger air bag, but have you tried the repair manual? Its got a huge amount of info.

I've got the ACT StreetLite Flywheel 13.4 pounds and can't really tell much of a difference in terms of street driving, even stop and go. (The 9.6 pound version didn't seem like a good cost/benefit tradeoff.) I do notice that under hard acceleration the RPMs fall very quickly if I don't shift really...

This car has a DOHC engine running off of a '93 2.2L ECU. Are cams still a piece of cake? If you think the PP6 has a chance of working I'm interesting in giving it a shot. Trying this sort of thing without real dyno testing is problematic, and as an engineer I hate guessing, but hey, this is a gutte...

I would love to buy something exactly like this: http://bbs.legacycentral.org/viewtopic.php?f=32&t=54599 After 3 years rallyx'ing an NA I really want to play around with the EJ22T engine. Plus I love wagons and it would be a hoot to take off-road. If anyone knows of a turbo wagon FS please let m...

I missed this thread originally, but the main thing missing is results. Did the ECUTune help performance? Fix a problem?

Thanks, I didn't think here was much benefit, but as an electrical engineer it's fun to tinker.

I had forgotten about EL headers; that sounds like a pm excellent next project, and a heck of a lot easier than taking out the cams

I've been scanning the forums but can't seem to find a stick thread on what's available in 2015. RobTune seems to be the only tuning option, but that only works for turbo engines. Are there any NA tuning options available in 2015? The PP6 seemed to be spec'd for NA, but of course that's been discont...

Softer rear springs do make the rear grip more, but under steer vs oversteer is a matter of relationship between front and rear grip. With rallyx you want a loose rear end, and the car is already really tail happy.


'93 Legacy Rallyx DIRTBOMB

Have you looked into the moores performance blast plates?? Might be an option since a lot of the 5 speeds seem the break because of the torque deflection of the actual cases. I'm on my third turbo legacy transmission. Never heard of 'em, but thanks, I'll check those out. Unfortunately the darn thin...

Just ran the numbers on a 5MT DCCD. Its 2mph faster in first, just 1mph slower than the RA I wanted, and the rest of the gears are just as close together. Gear, Stock 5MT, PPG 5MT, RA 5MT, 6MT, 4.44 5MT w/DCCD 1st: 18, 21, 21, 19, 20 2nd: 33, 35, 32, 29, 29 3rd: 48, 50, 42, 39, 39 4th: 67, 68, 57, 5...

Everything's a tradeoff. The 6MT's 2nd is the shortest, but also has a 1st that practically unusably short. That's a problem on an engine with only 160HP since 1st can lay down much more torque in 1st than 2nd to power out of corners. Going with a 6MT means giving up 1st for the most part. 2nd may w...

Those bags are really good on any coilover even if you are not rallying.

Have you used those gravel coilovers before? I'm curious as to how they're handling differs from my current setup, 2004 STi struts/springs.

Sorry, but a couple more questions:

Does it have electric windows? Did you keep 'em?
Have you replaced any glass with plexi?
What steering wheel and adapter are you using?

"Swapped out a 2nd gen 45 degree angle airbox and fabbed up a free flowing short ram style intake that goes to stock air box with a stock air filter. "

If you're using the stock filter box why bother to create a custom tube? Why not just use stock?

Thanks for posting this! Where did you get the exhaust system?

Legacy777 wrote:Why not just run your 93 Legacy stock springs?

Those are long gone The STi strut/spring swap had already been done when I bought the car. It sounds like stock Legacy springs would fit on an STi strut? The '93 springs or something from '04 to match the strut?

My '93 Legacy has '04 STi struts and springs, but I've lightened the car so much the ride is wayyyy too stiff, especially in the back where almost everything's been removed. Rally cross is much slower and bumpier than stage rally, and the back end is just being lifted into the air on many bumps. So....

Nice writeup, and a cool device. Is there any point in having one on an NA engine, or is this just a turbo thing?

Legacy777 wrote:Did you check the TPS wiring to the ECU to make sure it's good?

Hell, that was obvious, even for me No, I didn't check, but will this weekend.

After I posted I checked the oxygen sensor and that appeared to be way off of spec, putting out .01 volts instead of .1.2 volts.

Thanks!

Because of the ideal gear ratios for rallyx I'm going with the phase 2 transmission with the RA gears. Since the center diff can be swapped out later I'll leave that later. Ideally one would want to test the transmission gear swap first without throwing the center diff into the mix.
