You need a TEC 3!




NOT!

Thanks Dean. :lol:

My recommendation would be a Haltech, as they make a plug-and-play harness for the Legacy. Of course, that would require having someone who knows how to tune a Haltech.

And don't hold your breath on a programmable ECU. I figure if that car has been around for 17 years and nothing has come out yet, I don't expect anything ground-breaking.

I was looking into engine management when I had my Legacy, but I never found an acceptable solution that someone local could tune. I had this idea of swapping the intake manifold to the 02+ WRX one, which would allow use of a WRX ECU (with some modifcation), as well as WRX fitment turbos, intake, intercoolers, etc. Just a thought ;)

Yeah, a head swap would be part of the WRX ECU bit. Not sure I want to go down that road yet.....

Also, this weekend I finally swapped the LSD back into a 4.11 diff, so I have LSD again! (not the Berkley kind)

On the downside, I don't like the fitment of the '94 driveshaft that I put on to fit the new diff, so I think I will have to swap companion flanges, which should be easy as long as I don't screw up the backlash setting.

Still trucking, I really want to do a grounding mod next.

Update -

Rear diff flange swapped, so the correct driveline and the LSD are attached to the 4.11 case and ring. All I can say is that the rear end comes out really quick on gravel!

Paint-matched the A-pillar gauge pod!

Acquired EvoScan software + OBD1 SSM1 cable and am trying to map the correct ECU addresses for datalogging!

6-gauge cable grounding mod done!

Next: Coilpack upgrade from a mid-90's Impreza/Leg

Wow, did a lot this weekend.

New coil pack.

Tweaked plug gaps.

Swapped in a very low miles suspension setup from a GC, KYB AGX's and Prodrive P1's.

Swapped in the front STi knuckles and hubs - 5x100.

Fixed a jacked wire on the TPS, had to pull a connector pin and re-solder/crimp.

New knock sensor.

Slapped on a JDM VF-8, jury's still out.

Need: all rubber associated with sway bars.

Nice work! You'll like that suspension setup for street driving. It feels firm but not jarring and won't make you prone to oversteer.

wow that is a big weekend. Bet it runs awesome.

I need to show it to you guys at some point when I am down there! It's just an old car, but it's getting more fun every week.

Please do! It would be great to see your handiwork and to catch up.

Sitting in the BCT lounge right now getting an alignment!

Done, and it drives great and straight! Can't wait to drop the summer tires on......come on Global Warming!

Cory, impressions of the car as-is?

I can't wait to see it tonight!

I must admit, it's really sweet! Drives nice, and pulls well when you get on it! I kinda looked over the chassis and suspension while I was under it, and everything looks pretty damn good, save for the things you mentioned that you were in the process of replacing, (sway bar bushings...)

I like that car...

10,000 miles since I swapped in Josh's motor! Sweet!

That's awesome dude.

Dang, I haven't put that many miles on my car in 2 years!

Yeah! Great news. Here's to 100k more! :)

Some minor news.

Put the Hancook Ventus 225/45's on there, they are freakin sweet.

Had Thomas tint everything, he did a great job as usual.

Replaced the drop-link bushings on the RSB with poly.

Put Cody's 20mm FSB on.

Painted up the cheesy black trim around the windows, I expect this will be a yearly ritual. Painted the grill black too.

Next up:

Headlight clearing, 440cc JDM injectors (being serviced right now), Revtronix stage 2 chip (have it here) with the TD-04 and a new MAF once the injectors get back.

Sweet! When can we expect you at an autox?

Heh, when I shorten the seats (helmet won't fit right now, my torso is too tall), and the calendar stars align.

Fabbed up an in-fender CAI using parts of two generic intake sets, and a flange TIG welded by a friend. Pretty sweet, I'm glad to have all that plastic out of there.

OK, made some big changes.

Installed:
JDM 440cc injectors out of the EJ20G that I bought (serviced by Witchhunter, fast turnaround with all new O-rings)
TD-04 (again)
mid-90's EJ22 N/A JECS MAF
ECU chip by Revtronix.com for above items

Results: so far, a mixed bag. Obviously, a tuned chip by mail order is not going to be exactly right, but the new parameters to utilize the higher-capacity MAF and 440's were necessary. It has two maps, one for 91 octane at 14psi, and one for 93 octane at 16 psi. So far I have gotten the same fuel mileage as the old 380cc's. However, I have had to revert to the MBC once again because the chip is designed for a 10psi wastegate (newer TD04's), and mine has the 6psi version. The ECU just could not get around that, and driveability was suffering. Things are much smoother with the MBC, but I miss the staged boost control of the computer-controlled solenoid. This may get addressed down the road, being one of the first users of a product has some disadvantages. Maybe I'll just track down a new actuator or something.

I also put on the 3" bellmouth downpipe that I've had sitting around since I bought the donor car - it turned out to mate to the catback just fine with a 3" gasket I had on the shelf. That changed a LOT in terms of exhaust note. The car sounds pretty awesome right now.

So right now I don't know if the car is any faster than it used to be, but at least the injector and MAF capacity are raised up, and the top-end of the TD-04 is more responsive than before after 5000rpm. I'm waiting for the ECU to smooth things out after a few days of driving before making a final assessment.
Probably I'll have everything figured out tuning-wise about the time this motor goes....lol.

Are you going to bring it out to an autox this year?
