Whalen is good people. Sounds like a super fun day.

Any way you can pull your maps off? I'd love to have a look at them for science related purposes.
It was super fun. John is a really cool dude.

Already pulled the file for backup purposes. Looking for timing maps? It’s a bit different and alittle hard to compare as its speed density and all the units are a bit different, but you’re glad to have a look.

I have been driving the car purely for the fun of it. The shifter/trans still had some resistance and feedback when trying to shift and I started to suspect a bit of clutch drag. The only common part is the used jdm slave cylinder that I got with the legacy turbo trans. It appeared to be working fine but its really,really old. I put a new slave cylinder from an 02 wrx on and the clutch is smoother and the resistance in the shifter is gone. It drives even better now!

Honestly, I have no idea these days which ones have or don’t have delay valves, but I do not believe this one does. I believe this is the early 02 WRX/04 FXT part. The new one looks almost identical to the one I pulled off except for a few casting marks. The fitting is on top for a Banjo bolt and the bleeder slightly offset and angled behind it.

The one I removed:


The other 02 WRX part number has the fitting in the rear for the hard line and the boss on the top to mount the delay valve orifice (like my Baja turbo has) this new one does not have that or the removable fitting/valve in the rear like the STI 6 speed slave cylinders.

Car is parked inside for the winter. It’s waaay too cold to do any substantial work out in the garage and I don’t have the space to do so.

But I need something to tinker with over the winter so I started this I/C water spray project this evening.

I have been unable to find a Type RA shroud and I have been unable to order one from Japan because they are supposedly all gone and no longer in production. I removed my non spray shroud and made it spray.

Measured, marked and centerpunched for the nozzle holes.


Drilled holes


Used a small needle file to shape the tangs for the nozzles


Snapped the GC8 spray nozzles in place


Reinstalled the scoop backing plate and shroud


Water spray nozzles!



Over the winter I’ll route the lines, make a harness to wire everything up and gather/install the rest of the parts. I still need the auto switch so I can wire in the output from the ECU and figure out which tank I want to use for mounting in the rear since the OEM one I have goes where my ABS is. It will be fun.

I think I have the ECU figured out so it can control water spray on it’s own. With the auto switch “ON” it is set to start a 5 sec spray timer when boost exceeds 15 PSI. I can add IAT limits or whatever else I want to that later if I choose. The manual switch is set to start a 5 sec timer whenever it is pushed even if the auto mode is already engaged. Just need to hook up all the hardware, and still source the proper auto switch. I don’t think much more will get done for awhile as it’s a busy time of year.

The winter water spray project continues. In my quest to keep everything as clean and professional looking as possible, I really wanted to use the OEM switches. Finding a GC8 “water spray auto” switch proved to be alittle more difficult than planned. I ended up ordering a new one from Japan. Not cheap but really not bad for $47 shipped from Japan to my doorstep in MI.







Love the way it looks and matches the other existing switches perfectly! Next up, wiring them.

Cold weather and with a new kid as of a few weeks ago, not much has been done. But parts keep trickling in.

Decided on a tank for the intercooler spray. Mocking it up. Who else has installed the Spec C tank in a GC? How is it mounted? Trying to decide if I keep it as forward as possible or further back behind the strut bar. Forward means I’ll have to fill it from inside the car (a pain with a fixed back seat and harness bar.) and also means it will have to come out if I need to swap fuel pumps. Rearward would make the pump access easy and fillable from the trunk. Weight more rearward probably won’t hurt with the forward weight bias as is and its only about 6”. It would also mean alittle more involved mounting solution.

There was a good writeup on (i think) type-ra.com where the guy shortened the mounts and then made some holes. It looked really nice, I have it bookmarked in my build thread if you want to search haha.


I'll be doing the same thing too.. eventually.. when it's warm!

I think I remember seeing that. Last time I looked the pics were gone though. Also, I don’t recall if he had a rear strut bar or not. I know it doesnt really do anything, but it’s staying. It’s part of the car now, you know?

Weather has been above freezing so I’ve spend a few min in the garage.

Ordered some materials to fab up a mount for the water tank. Hopefully I can get to that in the next few weeks. I’m going to push it rearward a bit so I can access the filler from the trunk.

Switches are wired up and installed. I tapped illumination from the factory fog light switch. I took power for the switch and the relay from the cig light circuit. I still have to mount the relay in the trunk, run two wires back to it and the water line. I also have to connect both inputs and an output to the ecu but my garage is so tiny I cant open the passenger door inside to gain access to the ecu.

Then I still have to install the trunk full of parts waiting to go on from last year.
Also, some top feed conversion fuel rails and fuel line kit arrived. Flex fuel is in my future, I just don’t know how far down the road yet.

Also, was at my parents house over the weekend and my dad had these hanging on the basement wall.

Almost perfect condition fog covers. I think I might source the hardware and get them painted to match. Then I can just swap fogs for covers for track days to save the lights from getting damaged and drop a few lbs as well.

It’s back on the road for the season.


This water spray thing has been more involved than I envisioned. Almost there though. I am fighting with trying to get the spray timer to work correctly. I’m missing something in the settings.

For now, The manual button is a true momentary switch so it sprays as long as it’s held down. The auto button works with Throttle position, IAT and MAP currently and works pretty well. When I figure the timers out a bit better I’ll add that in.



Tank is currently zip tied into position about where I want it until I get some time to fab up the mount. That’s still looking like it’s a few weeks out. :(


Other than those issues it’s working out really well.

Had some garage time today. Went to my neighbors house and he helped me fab up what I wanted for the tank. Access to fuel tank remains clear, filler neck is clear behind the strut brace and accessible from the trunk and the whole thing can be unbolted and removed.

Replaced the seat siffener


Made some plates to mount to the tank with 1/8” plate.


Mounted them to the tank


Made some uprights to replace the mounts that came with the tank.


Put it all together




Still have to add some support, finish the welds and then clean it up and paint it. Then tidy up the wiring in the trunk. This has been quite a bit more involved than I initially planned for!

Honestly, I expect zero gain. I only hope to maintain more stable intake temps and therefor rated HP for alittle longer in sustained high speed, high temperature operations (summertime at the track)

One would hope it would do something since it was factory fitted and still is on some models today. I wanted to integrate this feature to my 24 year old L for a fun project and “cool” factor and admittedly went alittle overkill on it.

I will however be able to log IAT differences with and without it as it warms up to see what kind of effect it has. On temps and things like ignition timing and knock.

It should help for sure. My V4 TMIC heat-soaks pretty good in the summer. It's not uncommon for me to see 50C + in the intake manifold, especially after sitting in traffic.

Looking really good man! +1 for ignition map..."I'll show you mine if you show me yours" ??

Just been having fun with it. Took it to a Subaru cars and coffee a few weeks ago and been driving it around.

I have a bunch a of new parts to put on but have not gotten around to it yet.

Clean looking car and sweet build. Reminds me of my first green L ej20k swap, but all I did was disassemble the block and heads, inspect and clean and replace all gaskets. My ej20k ran great on US 93, never a problem. I took the same route, just adding wires for the boost solenoid and a few other wire mods. Then just repinned and swapped some wires at the ecu. The jdm ecu ran superb, but I eventually got a apexi powerfc so I could get it tuned after building a hybrid 2.5 later on. Seeing your pics made me remember mine, it really wasn't that horrible to do.
