Finally I am on the home stretch with this entire ordeal. To give you a brief history with my situation, I had thrown a rod through cylinder 1 last october. My mods were:
CPE STANDBACK, CPE CATTED DP, CPE SINGLE EXHAUST, CPE FRONT MOUNT, CPE ENGINE MOUNT, ETC.
The engine failure happened about 1 week after I installed the front mount. Not to say this was the cause, just stating the facts. The engine detonated at a low rpm, about 4k and at a low gear and speed. It was a mystery so to speak but the evidence showed a piston that had a hairline fracture all the way down the center creating 2 halves, and a rod exiting the block which is obvious in the pictures.
Since this I have purchased a brand new built block from protege garage, with arias pistons and pauter rods. A brand new head from mazda, the only one in the country at the time. The valves were damaged and I decided not to take any chances with a rebuilt head. The atp turbo kit gt3071r, upgraded fuel pump from protege garage, spec stage 2 clutch, and upgraded my standback to V2.
The car was started yesterday and she sounded amazing. Idles like stock but the exhaust you have to hear to believe. There is a gurgle that doesn't speak "I AM STOCK". And obviously she doesn't smoke like she used to because I have a very well built turbo now and not the factory K04 that i'm convinced has faulty seals on every single speed6. You are just never able to tell on stock vehicles because of the 3 cats that conceal this.
The builder is adjusting the clutch today and I should be driving this tomorrow after he takes it out and tests the AFR's so I can break it in before we slap it on his mustang dyno for tuning. On this dyno, stock pre-2008 subaru STI's put down 220 wheel hp. My car with all the bolt ons before the failure put down 235 wheel hp and 260 tq. I am hoping for 350 wheel which will make her produce 425 hp at the crank. That should be good enought to tackle new M3's, rs4's and hang with r8's and 5th-gen 420hp 911 turbos.
Any input you guys have on my build or advice, I appreciate greatly. Please reply and i'll answer any questions you may have. Thanks.

going with the new head on this build i think is critical and is something that was sadly not done on the first 'build a beast' thread. subbing for future results.
