Default STi to RS questions

I know many questions come up with these swaps, but I just have a few of em.

In doing the swap I originally wanted to do a full USDM STi swap including the Engine, tranny, rear end the hubs with the brembos. I've been told that attempting the wiring myself would end in catastrophe, and having a shop do it, would be about as expensive as buying an STi (assuming 10k for the car, 7.5k for parts and 7.5k for labor = 25k STi), but wouldn't really have a factory feeling car.

I would most likely want to do the wiring myself, but would need to read a whole lot before even thinking about it. I'm certainly not stupid, and pretty handy with a wrench, but would quake with fear as a beheld an entire wiring harness not inside the car.

So, I'm curious if you could do a STi block, or a Crawford block, a GT30r and then reinforce it with stronger gears and drive axles. Has anyone succesfully transplanted just a block and ran a turbo motor on the stock wiring harness?

Basically, is there a more economical route to doing this swap whilst retaining some reliablity? I'm thinking I want to try to get a car for less than 10k, and then maybe spend an additional 8k on the swap and supporting parts. Any ideas are totally welcome, or even price quotes on the swap, I'm all ears.

aight check this out... i was able to procure an entire car for my wrx swap, and if you do the dash swap, which requires the dash, air/heaterbox, dash cross bar, pedal box, steering column(with the wheel), and console, you can swap all that stuff in as well as the complete STi wiring harness. the only wiring necessary is to change the headlight and taillight leads, as well as a little bit of wiring for the tank, and the doors. other than that the whole sti wiring harness will work provided you have all the sti heater controls and gauge cluster... i understand that you would have to accumulate some more parts in order to do it this way, but it would cut out your wiring headache.

Call ECS. Parts + labor for the STi swap w/ dash (The way to go, I love mine) was 13k ish last I remember. You can also cut a lot of cost by starting with an L chassis and just doing the RS or v5 exterior conversion. Everything you will be swapping, its pointless to spend the money to get RS stuff then pull basically all of it out. 1200 bucks for a full replica v5 kit (fitment on mine is great) + 1500 rolling chassis L. Thats almost 7 grand cheaper than youd pay for an RS, without paint.

i second fourstrokephysics. i did everything myself, including interior AND tank, and all i had to wire in is headlights,foglights,tailights,power windows,locks (i dont have P/M),CHMSL,wiper motor, and corner,bumper and sidemarkers. a total of like <60 wires or something like that. not a big deal. if you use the sti fans you dont have to even wire that. i used spal so i had to anyway. 2 wires each (four on harness)
i recommend that.

stuff like the front lights are mostly 2 wires, youd have to be pretty f'd up to screw that up, the wiper motor and tailights have damn near the same colors, also the windows and locks. not exact, but most are. you get the point. i dotn have a radio but i suppose that would be a little more work, especially if you have a sedan, really the same either way though becasue youd have to extend the rear speaker harness anyway.

the point im trying to make is that it was MORE cost effective for me to pay for an 05 sti interior, and no merged harness. and it might be for you too. plus in the end, you have a better interior
good luck

For your info: I did a complete 04 USDM STi swap by myself. I had one or two people help during small portions of the swap but it was pretty much by my lonesome. I did everything you said you want to plus the fuel tank, harnesses from front to back (engine bay, bulkhead, front, rear), STi radiator and fan assembly. There is some splicing to do but honestly its not bad at all. If you get all the harnesses its pretty much plug and play. I spliced: Headlights, tail lights, HVAC controls, blower motor, all 4 doors, domelights/sunroof/power+folding side mirrors... and thats pretty much it. Potentially you may have to splice: column stuff, and radiator. Its really not that hard.. its definatly very time consuming.. and as much preperation & research for it as possible is a huge plus. I kind of went into it with mediocre preperation and I ended up having to order a ton of stuff and wait for parts..etc etc. Im still waiting for a new gas pedal because I FUBAR'd the last one (atleast I think I did).

*edit*

So essentially it is a very cheap thing to do. (Compared to prices of stis) 10k for the car is a bit much. I saw a rally blue 98 GC on rs25.com for 5 grand. Depending on how much into pure performance you are, I would start looking at 93-95 impreza L's. They weigh considerably less then, say, my car. a 2000 2.5rs. My car weighs in at 2800, a 93 L weighs in at like 2400 or something.

It would prolly be a pretty stripped out car with two brides and a roll bar, so I'm not looking for many accomadations, just something that can get me from point a to point b at mach speeds. It's also going to be my track bish, so maybe an L with the RS body kit would be cool. I know that a lot of the Ls are 2WD, do they still have the ability to mount up the rear diff and such?

Yep, if you do the full conversion with the gas tank, subframes, etc, itll all bolt up to the 2wd chassis, as all your using is the chassis itself. The sticky at the top of this forum explains the RS conversion, its super easy. Call james at ECS, they did my swap and I'm extremely pleased with it

I was all bummed that I wouldn't be able to do this, but the more I think about it, the more I want to. For some reason it's super hard to find RS's right now, I've been looking for a few days, and the only ones in my area area are like 9k and have like 150k miles. If I could get a cheap rolling chassis, I could just bus it until it gets shipped back with STi swappage.

BTW, where is ECS located?

I don't work for anybody now! There are a lot of reasons behind me leaving, but the biggest one was that keeping up with school and working 60+ hrs at the shop was next to impossible.

Found a cleanly installed RSTi I'm going to drive pretty soon. Let's hope the install is better than I would have done, hehe. 2 door STi ftw!
