Some other changes include 02 WRX coil pack conversion. All but ONE of the stock EJ20G coil packs were cracked and fell apart under the boot when I inspected them. Since converting, Ive noticed a lot of improvement.

I also installed two prosport gauges, boost and oil press. I used a OEM gauge pod with a custom carbon fiber gauges plate I made myself.





Ive been chasing a couple other issues with the swap. I had to modify the brake booster vacuum line out. With the way it was on the stock RS booster, the hard line comes out and makes a 45* bend to the right, putting the line directly under intercooler. This caused problems with the hose being cut by the intercooler, or getting kinked from the tight bend. I simply cut the hard line at the bend so It comes out strait. Voila! Fixed.

It recently has been going in and out of limp mode at random. Im going to do some regular maintenance tomorrow (plugs, clean maf, new air filter) and see if that helps. The only code Ive had is a MAF code...we'll see what happens.

Anyways, Ill post Winter setup pics ASAP. Im REALLY happy with how my winter look has come together.

VictoryLap...Thank you SO much! I really appreciate your kind words. This car has certainly been a journey and I have loved and hated a lot of it. It is ridiculous how attached I have become to this machine, but I feel very connected and very close to the car. It has become a part of who I am and defines who I am. Im at a point in my life now when im finishing my college career in may and will be off into the real world of work. Im very much excited for My beloved RS to help take me into the next chapter of my life.

Stew,

This was a great thread! It really brought me back to being 17 and doing my first swap. It was pretty much the same ordeal, me and my buddies,trial and error. I still remember how great it felt to have it start and run for the first time! After watching your Videos and seeing your pics, it put a huge grin on my face. Good for you guys! Congrats! You guys really made me remember why I loved doing Subaru conversions, and even got into this game.

Thanx Paul! You actually sold me the motor...dunno if you remember. It was a great experience and I definitely had some great help from my friends. I also spent several weeks studying the diagrams and reading threads. Rob also was a big help, so much thanx to him too. But yeah, It was a great feeling and I love it.

I just need to remember that when I get frustrated with it. I keep chasing down little issues with it. IT likes to randomly go in and out of limp mode. I take care of one code, it throws another. really, really frustrating.

Steven,
I was un aware that you bought your motor kit from us, but I'm glad you did! Thanks for the business. We appreciate it very much.

Those EJ20G setups are VERY hard to get running right. I would recommend changing all the intake gaskets out. As well as the fuel injector o rings. Change the plugs and gap them to .28. Thouroughly check the coil packs for crack, and then pressure test the intake setup looking for boost and vaccum leaks. If all else fails, check that the timing is spot on, and that the coolant temp sensor is sending a reading to the ECU.

Also make sure that your Green Test Mode connectors are not plugged in by accident causing your car to stay in Program mode. That will throw the whole car off as its cutting the fuel pump and fan rational circuit on and off.

I have done the 02 WRX coil pack conversion and just put 4 new NGK BK7RE plugs in gapped to .28. I still need pressure test the intake. We'll see when I have time for that...!

Wow ! So its been almost 3 years since I've updated this...Or even been active on RS25. I've got a renewed interest in working more on my RS, so I've re-upped my premium membership and returned to the forum.

In the last 3 years my life has changed considerably, most notably that I've graduated with my bachelors, moved now to the east side of Michigan and started working full time for a major automotive OEM.

In this time, my RS has sort of been on the back burner - Due mostly to time, not having space to work on it (apartment living), and not having my tools at my new home (again, no room). Little fix-it items had started to become more and more frequent with the RS, so since working full time (and having a little more cash) and needing reliable transportation, I picked up this little guy about 2 years ago...

When I Picked up:


2004 STi:
Engine
K&N typhoon Intake
Godspeed Top mount
Grimmspeed ceramic coated crossover
Megan turbo-back exhaust
MBC
Mishimoto radiator
Samco rad hoses
Gates racing timing belt
Pro-tune

Trans
ACT Street-lite flywheel
Exedy stage 2 clutch
TIC Holy shift kit

Suspension/Brake
RCE Yellow Springs
Whiteline steering rack bushings
Hawk HPS pads
Slotted rotors (front, not sure brand)

Interior
Agency power shift knob
Greddy Oil pressure gauge

Exterior
Carbon fiber front lip
JDM tail light mod
De-badged front grille
Cleared headlights

Wheel/tire
OZ Racing 17x8 Ultruleggera
Nitto NT-05 - 255x40x17

/\ This /\ Is a wonderful machine, and I'm really lucky to have it. It makes a phenomenal DD and is a complete riot to drive. It lacks however the character my RS has always had. I've been busy with work, other hobbies, life, and just have sort of let my RS sit parked in front of my apartment, forgotten.

But now is the time, and although I don't yet have a garage (Yet...) I've started gathering parts to fix some little things, improve others, and get my RS back to daily driver+ status - This I'll begin to document on the following posts/pages.

Thanks for reading, it feels good to be back on RS25.

First things first:

Items to fix that keep me from driving the car:
Leaky, broken intercooler piping. Anyone who's familiar with older JDM swaps, particularly the V2 ej20g, knows that any plastic components aren't long for this world. I've struggled with the intercooler piping - charge tube - It tore at the flex joint, I've patched it, and fiddled with it, but it just needed to be replaced. It would boost leak like crazy And eventually the TB coupler dried up and the intercooler would fall off.

I ordered a Samco IC hose kit for V1-2 WRX. This set required you to cut the stock tube back and slide on the new unit. You can see it installed below. I cut the stock piece about 1/4" in front of the first hose clamp. Its a good fit - and so nice and flexible and should be able to be installed and removed several times without breaking.


I haven't yet installed it on the car, but I'll be sure to update when I do.

Next up - intermittent limp home mode due to suspected bad MAP sensor.

This bastard - New from Subaru is ~$350 :eek:mg:

I've got a used one on the way from a member on NASIOC. Will update when installed.

Gauges

I had previously posted my gauge setup. Both sensors - boost and oil pressure - failed. They didn't last long at all really. I'll never buy cheap gauges again. It's so depressing getting in the car for a drive and these two useless, glowing gauges staring you in the face to remind you how broken your car is.

Not for long!


:banana:
Greddy electronic boost and oil pressure. Really nice quality, small sensors (can fit the oil press. sensor in the dummy light sensor position), doesn't cost a million dollars, doesn't require a controller and reliable. The Greddy oil pressure gauge in my STi is going strong for almost 2 years. They are, however, discontinued so these were hard to find. Oil pressure gauge is still in transit. I'll update when installed.

I also made a new gauge face plate, as the old one was warped and broken.


Hoping to install soon - !

Samco Sport IC hose set installed:



This solved a lot of drivability issues, including the MAP code I thought was a bad MAP/vacuum sensor. The car now makes full boost (11-12 psi) and holds it, no limp in mode.

New boost gauge is installed. Again, GReddy gauge quality is fantastic. The sender is really robust and comes with a nice mount. All sheathed wiring with a weather-pack connector at the sensor - really makes install easy. Just have to connect power/ground/ign/illum. in the cabin for the meter itself. Its a shame they're discontinued.




The gauge face itself is a perfect match for the stock 98 cluster. The amber backlight doesn't really match at all, but no big deal for me. Only have this daytime shot now, will upload more and day/night photos when the oil pressure gauge arrives and I have a chance to install it.



Tried to fix a couple other issues today as well - blown out bushing on the wiper motor with Autozone wiper repair kit. Also trying to repair the windshield sprayer - seems as if there's no power at the connector. Was a little too cold today to finish these though.

One other issue - driving around Monday I got a CEL. Checked it out - Code 22 - Knock sensor. The current one is cracked in two places. Resistance through the connector to ground is also really high, according to my FSM. Will try to get a new one tomorrow at dealer.

More tomorrow, I hope.

looks great. love the progress, and absolutely gorgeous STi you have now as well my friend. Always loved the peanuts with the STi spoiler.
Thanks ! I already feel really good about the progress, even just this week.


Called my local dealer this morning - no knock sensor. :( ordered it online, hopefully have it in a couple days

OEM knock sensor came in. I found the old one had cracks in two places. Was setting code 22 and giving a lot of knock retard. Popped this new guy on and power has improved - car pulls pretty good now.

I've been sick the last week so I haven't been able to work on the car, BUT! my oil pressure gauge came in and I got time (now that I'm feeling better) to install it tonight.

I figured out with these GReddy V2 gauges that if you just wire the red to switched 12v, the gauge does an opening sweep on start-up. So after re-wiring that circuit, I added in the oil pressure wiring and mounted it up.




again, the black face, white font and red needle match the 98 cluster perfectly. I just wish they were back-lit Green!

My favorite part about the GReddy gauges is that the pressure sensor is small enough to fit in the dummy switch position. Just unplug the dummy switch, pull that bastard out and screw the pressure sensor in.

Alternator out


Sensor installed. Use Tef-tape. I think my PS pump is leaking :D


Alternator back in - You can see the sensor peeking out there.


Ran the wire through, connected and done. Voila.



Again, lighting doesn't match but they're quality, Japanese made pieces and I got them both for about $300. Since they're discontinued, a lot of places are blowing them out.



All done for now. I've got some fresh Rotella-T to change oil this weekend, otherwise she's ready for the ~700 miles We'll cover going to Sno*Drift 2013. :D

Until next time...
