Default Is it worth building out a 2.0 or just swap to a 2.5

I have gotten my self deeper into my Sube than i figured i would and now im looking at it as a serious project. I im in the process of doing a 1-4 PPG gear set, Cusco 1.0 and 1.5 LSD's,a stage 3 Clutch, and aluminum drive shaft to the trans and diff set up. I was building this up as a 430-450whp project but now im starting to wounder if i should just add a 2.5 swap to the project list. Tomei has a 2.2 stroker kit/ short block lit as well as a 2.6 i beliver, there both pretty expencive but i figure there are so many solutions. I really only want a realiable 450 - 500max whp to use this as a back up time attack this year. Any ideas? The rest of the car is fully built, every possible suspension option, all frame supports, doing a full cage, 8/6 pot calipers, Utec programer, Full race exhaust, header, fuel cell, and im sure the list goes on. I just dont totally know what to do about the motor.

I bought a wrecked STI for $8000. for that price I get the 2.5 engine, upgraded tranny, drivetrain, brakes, hubs and diffs. I've swapped it all into my 03. Seems like this might be cheaper than just your transmission alone.

Just something to think about.

Well I think since you already have all the upgraded performance extras on your WRX an STI donor may not help, well unless you want to take the engine, tranny, and maybe the brakes then sell everything else.

If you do that you could end up with getting some money back, plus then you have a stronger STI 6 spd and the stronger engine you wanted as well.

I would buy a donor STI now that i think about it. I am buying a WRX to swap over into my Legacy and it will be well worth it in the end
