you planning on doing this your self or having some one do it for you?
cause here are the parts you will need for a "basic" swap (meaning engine only no tranny)
-engine you plan to use
-ecu that goes with it
-as complete of a wiring harness as you can find
-jdm or modified crossmember
-tbe (whether it be stock or not it will be nice to have)
-fuel pump
-electrical tape
-and alot of downtime for wiring (especially if you want to do a usdm STi swap)

Yeah, it is not a simple swap like an sti engine into a wrx is.

Most engines don't come with everything needed for a complete swap, and i'm not even talking about little things that add up real quick like MAF sensor, Boost control solinoid, various lines. Don't expect to pay under 9K just to get an engine running in your car. (and that is keeping the stock trans... no upgrade)

You can get a used Sti engine for 3-5K, if your talking 6-8K for a new engine then that sounds about right.

for the usdm sti you will also need the prdal assemb. since its drive by wire check out aerosim they will do a whole usdm sti swap with dash for 12 or 13
they say they get their sti's for around 10k or so

I did the same thing and it will go strait over. However, It would save you time and money to just buy the sti block for 1k and put all of your heads and whatnot in it. Then just slap on your turbo and all. Note, you will have to use a front mounted intercooler.

That's not true. As stated, you'd need a different crossmember(WRX, Turbo Legacy, or other Turbo crossmember...each have various issues you have to deal with, as they are slightly different). You can use a top mount intercooler, you are not forced to use a front mount.

Physically, it will swap fine, once you get the appropriate crossmember. Beyond that, it depends. If you want to swap over an entire wiring harness, you'll have to address issues with some of the electronics in the dash, but it's not a huge amount of work, but it's not all plug and play.

There's a slew of threads on this issue. The trick is not to look for one thread on the entire swap. It'd be a 30 page manual that you'd never read. You look at each portion of the swap indepedently. Look up the wiring, look up the physical EJ257 swap, etc... There's a ton of info, you just have to spend some time to look it up correctly. It also varies greatly depending on specifically how you want to do the swap.

The $13k is an approximate price. If you would like one with lower miles etc. etc. it might cost more. We just picked up my 05 STi w/ about 2k miles on it for $11,550.00. When all is said and done it should cost me about $15,000 for the entire swap. The reasons for the higher price is because i wanted the 05 for the helical front LSD, AYC, and the new 5X114.3 lug pattern which will all come with the swap . Hopefully my car will be done within the next few months so I can start posting pictures of her!!!

Oh, btw.. I have a 2000 RS coupe not the widebody GC that steve has.

Bolts right in. Just drop the engine in, plug it in, and start the car. If you have to ask these questions, you are probably in way over your head and should pay someone to do it for you...

There are about 4-5 threads in this forum that go through blow by blow exactly how to install and STi motor into a GC. Only a handful of people have done this yet, but the ones who have took the time to document it. So, get off your arse, and look through the last ten pages of this forum and you should find exactly what you need. Do NOT use your search button, use your scroll and read every title until you find the right ones. The information is readily available...
