Default 02RS25's BRP 2.5 RSTI swap

Good Day Iclub!


So the time has come! I bought a used EJ25 Shortblock from a supposed 2006 STI. Im still doing the research as to how to properly verify engine via numbers. The seller is a good friend of mine and has agreed to return all my $ should the tolerances be out of spec or if it’s not the block he thought it was. Its simple, I have a bugeye BRP RS and want to go faster, but want to built it myself on the way. My original plan was to do a custom build with 500+ but now im thinking im just going to build to OEM STI specs. Im in no rush to get this built. I anticipate and gave myself 2 years or so for the build (engine,tranny, diffs, hubs, ECU, wiring) everything! Same chassis, different car.


So, the reason for this thread?
1 )I want to open a thread up so people can throw down their ideas/comments/ suggestions. YES, I have been doing lots of research on the web and with fellow STI owners. I just want as much input as I can get.
2) Me being on a bit of a budget, I am going to be using used parts for different sections of the car/driveline ie:
WTB:
Stock TMIC, stock BOV, stock turbo, stock external engine/ tranny (mounts, shifters) parts
Stock 6spd, stock hubs, etc.

I will be using brand new internals (pistons, rods, bearings, valves, springs/retainers, also will be doing a thorough inspection on used OEM STI 6 speed.

I will keep this thread updated with pictures, comments, parts as I continue the RSTI build.

Im really looking forward to this build!






shortly after picking up the 2.5 STI shortblock, my headgaskets on my RS blew

now i have 2 engines to rebuild. LOL

Picture update. I am still having some trouble loading pics on this thread. ill have to re direct you guys to my Iclub thread where all the pictures are. sorry guys!

Nasioc,
I have a question for you experienced Subaru engine builders out there. So, my HGs on my RS blew a week ago and I will be pulling, R+R HGs, and also replacing water pump, oil pump, timing belt, tensioner, idler, as well as a complete gasket replacement. heads will be machined and given a valve job. Now, my question is: Should I rebuild entire longblock at 255,000 miles? i understand its recommended to rebuild longblock when rebuilding heads on a high mileage engine. Is this still true for our flat 4s, where our pistons seem to net eachothers force? as opposed to a Vtype or Itype engine that has all its cylinders pushing down on one crankshaft and its bearings...

nice! ya im still at the measuring of tolerances and clearances. but pretty soon here im going to be looking for maybe a set of STI heads, up pipe, turbo, headers.

I have a WTB: STI parts thread on I-club, but i will make one here as well. Im looking for mostly used parts, with the exception of the obvious stuff (bearings, crankshaft maybe, gaskets, bolts, etc.) I will use that FS thread to update my build on what im looking for next. Thanks bro!
