Just to start things off, I just picked up a USDM STI swapped 98 RBP RS. This is my 7th Subaru and the first time I've made a journal like I should have with the other six I've had. Purchased the car 8-26-13 from beachbum12tree. I believe I have a good foundation to work with that I acquired at a decent price. Already have a built engine in my garage and some other goodies, but life demands its own priorities so it will be a slow process to get the car exactly were I want it. Anyway on to the good stuff :burnout:

On the drive home I noticed that the front lip came loose in one spot...or so I thought. Upon closer inspection I found this :(

Yeah whats holding the other side to the bumper...a paper clamp :bitehard:

Seller did disclose that the LH fog light stopped working and I found out why.

Some of the wiring that I'm going to fix

Update 10-8-13
Have fixed all the issued pictured above and a few more I've discovered while running those down. Good news is the harness merge goods pretty good...proper solder and heat shrink...I have found several vampire connections though. I am sorting things out a little bit at a time.


one fun find

Also sanded down the battery tray and area to treat rust, then sprayed in some Dupli-color truck bed coating to make it a little more resistant to damage.

Have to hunt down some head lights soon too for when these are totally useless

Think I have fixed the valve cover gasket leak as well...hope it did anyway. If not I'll find out whenever I finally start driving it around. If it still leaks I'll fix it properly and change all the spark plugs.

Girlfriends FXT

My little helper

Just because

Small updates:
Supposedly all the car needed for cruise control to work was the GD STi switches. Well I swapped out the entire RS assembly for the GD STi assembly. Well, I still haven’t put my finger on why the cruise control doesn’t work, but I have eliminated a lot of potential reasons. Anyway pedals were installed. RS vs GD STi Pedals: GD STi Vs 98 RS Pedals Photos by tad_07 | Photobucket

Need to remove this material in red to fit:

While I was installing the pedals I discovered these lovely little surprises. One of the heater hoses was too long and was pinched off and jammed under the clutch master cylinder. Hard to see, but the starter was only held in with one bolt….:unamused:

Also managed to find these pretty rare JDM STi Recaro seats (Recaro SRD’s if I remember correctly) and I love them. They are a huge improvement. My old V4 seats I had in my wagon are a close 2nd place and my BRZ seats (except the damn head rest on the BRZ seats).

So much Fun stuff has happened since my last update and made me not even want to even talk about it. On the bright side I have collected some new parts and two 06 STi's ....ok one is my girlfriends new car :)

Any way on with the lastest awesome findings-
Driving home from work I noticed my coolant temp. gauge start to read hot, radiator sprang a leak on me...or so I thought. Scared to hurt my baby, it left me stranded on the road side after working a 12hr shift and had to wait ~2.5hrs for a tow truck. Had another shift the next day so I packed a lot of water with me and drove her as easy as possible 60miles to and from work eye balling the temp gauge the the whole time . As it turns out the radiator had already had 2 holes punched in it...yeah wasn't happy. The a/c condensor bolts were sticking out far enough to make contact with the 08 radiator koyo radiator that was in there. Whom ever put those 2 hose it in patched them with JB weld or another simular epoxy. I assumed the leak was coming from either patch so I removed the epoxy with a small propane torch and used some aluminium braze to re-seal the the holes.

As it turns out the GD STi fans that were in the 08 radiator did not sit properly and rubbed at the bottom of the rows and cause 3 holes

I made an attempt to patch those holes, but got the braze or the radiator itself a little too hot. The patches didn't hold at the pressure I tested at so I put in a V4 STi radiator and its fans since I had it on hand from my old rhd wagon swap. I do now have a back new version Koyo GD STi radiator w/their hyper v 36 core [since I have 2 GD's aswell it just makes since to have].

While I had the radiator out I made another nice little discovery that I don't know how I've missed this whole time or when I was looking it over to buy. Can you spot what is missing???

Was making a big order from the stealership for tune-up stuff on the GD's anyway, so this just added to my list. So dealing with 2 other cars now, which is why I haven't made any updates in a while. There is more to come as I finally decided on a set of cams for my engine build. Going with Kelford R-199-B cams. Now just have to decide on injector side and manufacturer, but think I have that down too. May have to ditch the MAW tgv if they don't work well with my intake mani's, if they don't the its either JDM manifold time or JDM top feed tgv's

Well found out why I didn't have cruise control after going through the harness…it was not wired in at all, as in they weren't even there :/ All fixed up now though and made a little diagram from the service manual for how it is actually run since I'm using a 05 steering wheel and cruise control switch.

I had the chance to swap out to 06 STI knuckles and wheels for my 04 stuff, but that meant the KW V3's that I loved so much had to go. I must give a big shout out to Race Comp. as I went with their Tarmac II coilovers 😊 and I actually like these a little more which is hard to believe. Luckily, the 04 tranny in the car was a late 04 and already had male/male axles with the correct abs ring; so I did not have to swap the sundials on the tranny. While I was at it I went ahead replaced the tranny and diff fluids with the correct Motul oil, put in new axle seals all around, and replace the bearing in the camber plates.

Had a bid of fun on the way to work at 4am in the morning, I threw my alternator belt and was still ~15miles from work :eek: Well, I have a good Optima battery in the car so I knew I would make it to work. After looking at things closer once I got to work I realized the rubber in the balancer separated & I needed another (and belts) to get back home without a tow. Luckily, my girlfriend picked up some belts for me and brought me the pull off the built engine sitting in my house 😊.

Now for the sad part, I will be putting her up for sale sometime soon. When I moved here to Texas I thought I would be able to hit autocross like I did back in La., but realized after going to watch 3 events that things here are not like they were there and not like I hoped for. I have played with the idea of going to MSR or similar places, but only having cars and no truck and trailer just in case killed my prospects of enjoying any track time and one of the things I love to do. Through being a father with custody in and working on my MBA and I have no time to do what I'd like to do anyway. I am not out of the Subie game as I chose my built 06 STI in place of the RS. Now I just need decide on getting a truck or import something I've wanted a long, long time…a 70-72 Nissan Skyline Coupe.

So you have to inspect the harness for areas where it's soldered? I thought beachbum12tree said he had that taken care of by Forman soooo there shouldn't be any soldered wires in the harness o_O

Believe that the are all soldered connection, but are wrapped with electrical tape and not covered with heat shrink. I have OCD bad when it comes to this and why I am usually the one to do any harness conversions and why my friends get me to do theirs or help them with theirs. I only suspect this because I know that is the way the ic sprayer pump is done in the trunk. Just hope I don't have to bust out the soldering iron to separate the wires to get the shrink on and can just de-pin them and slip on the heat shrink, but that also depends on how the connected the wires too ( Y vs. --)

how does that s201 scoop fit? also more pics!
Seems to be ok, but I didn't install it and don't have a reason to remove it yet.

Updated---pulled Bakemono scoop & fit is perfect. Also the GD under the hood piece fits just fine as well, but you have to make your own attachment points for the front side of it...the rear you can use stock mounting locations.

Had fun at Gillman Big Event 5. Car isn't really a show stopper, but put it in anyway just to get a good parking spot lol. Got a fair amount of work done to her before hand considering how busy life keeps me. Updated the first page with relavent info.

Tad! Holy crap! I didn't know you posted on here. ( I bought seats and an exhaust from you waaaayyyy back - 2013 or 2014?)

You do okay in the flood? I left Houston just before it hit.
