Cool! Do you have an opportunity for some before/after comparisons (either dyno or 1/4mi)?

Hey I got lost while reading posts, lost where I was and dont want to start over again so ill quickly ask my question. on a 05 2.5rs are the crank and/or rods forged. Or I guess are any 2.5 (STI or others) forged. Any info would be great. Even a title for me to search or link to a thread stating so. I did try to search but came up with nothing. But that could be bc I go brain dead wen I'm on the Internet.so for searches If it ain't obvious I won't find it unfortunately.

So searching for "forged crank" or "forged rods" isn't obvious?

I did try both but put ej253 in front and my built motor thread was first, i also tried "forged internals", "do ej253 have forged parts" i have tried a few but I have never been able to find anything. But then again I just saw a thread in the classifieds and the title was 02-07 impreza WRX/STI parts. And when I tried searching that title nothing showed but wen I put in "what parts are forged" then it would pull it up. Idk if I just don't understand the Internet or what but that little problem was confusing the hell out of me last night.

So I have a few questions. In terms of swapping all the different subie engines, does anyone know all the parts that are interchangeable? Like will a 2.5 intake manifold fit a 2.2? or would it even increase the flow if it did? Also what about the intake spacer? Does that change over from 2.5 to 2.2? How about throttle bodys? Are they interchangeable, or would it make a difference? Are there any ignition coil upgrades for a 2.2? I have not seen any. Is a 2.5 coil higher output? Would these be interchangeable? Just some thoughts and questions as I have a 2.2 but dont want to swap to a 2.5. I like the reliability of my 2.2, at 260,000 it still has 185 psi in each cylinder, doesnt burn any oil, and has pretty good power. Although I do want some more Any thoughts or opinions are welcome.

As a noob, I think this thread is in need of an update. Many of the products and companies listed are no longer exist. The theory behind the mods remains valid.

srs **** that was popular years ago. maybe you can find one used. there are a handful of piggy back chips. honestly the stock ecu can handle all but the most intrusive modifcations. I had a whole bolt on set and on a stock ecu and it ran well and fine. no codes

it wasnt till i got a vipec where i unlocked the potential ( christ i sound like a yugioh ***)

You can try to find a PP6 piggyback ECU or use ROM Raider which is an open source software to tune.

Tuning is always beneficial, even with NA.. and even stock. However, with a full exhaust, intake, maybe even cams or something, you're looking at some solid NA gains with piggyback ECUs and open source software.

Keep in mind, not anywhere around what a turbo model would gain, but still gains none-the-less.

You do not need to go hunt down and old SRS tuned ECU. The tuner who was doing those reflashes is back at it on his own and no longer with Crawford. His company is Delicious Tuning. I have his stage 2 tune with delta 1500 cams in my '01 RS and it definitely woke the car up quite a bit especially over 4500rpm.

I agree, delta 1500 cams gave my car a nice punch 4500 and up. Very happy with delta. For those with non tunable ecus (non jecs ecu 03 and 04) the aem fic works nicely contrary to others accounts. With full exhaust and cams stock ecu tries to add too much timing above 5000rpm. At red line I took out 7 degrees. These are facts! Also uel headers sound awesome with full exhaust and cams.

I like this approach, building up an engine in steps. The full experience. I'm sure one learns a lot more doing it this way.
