Porting pr0n:
Yup, that's a pretty big gaper.
2/14/11:
Fun ported bits from Mil.Spec!
brand new 64mm ported throttle body (stock is 58mm)
majority of plenum ported
majority of runner ported

Sad sight:
The car is currently on the lift getting inspected.
Transfer case started howling and puked it's fluid all over the road last night.
Eby (Don's service manager) confirmed the transfer case was overfilled with fluid and documented the fill and drain were untouched with factory paint seal intact. He also said this is the 2nd they've seen like this this week.
I just off the phone with them again and they're saying they filled the fluid to the proper level, cleaned everything up, and it appears all seals are intact and the fluid was coming out of the top case breather tube. After test-driving the car they're saying everything is functioning OK and not making any whining or howling noises. A case has been opened with Mitsubishi with everything documented in case a problem arises in the future, but for now they're saying the car is ready to go. I'll of course listen for any noise very carefully and if I don't feel it's 100% I'll be leaving it at the dealership.
2/17/11:
Just a small detail I've been wanting since I bought the car since my IX had it too.
2/21/11:
My coated PPI Extreme ported exhaust manifold from SPC in Arlington, TX is done! Should be going on this Saturday...I plan to get the initial pre-manifold baseline dyno done on Friday.
2/25/11:
Well, back to the dealership the car goes tomorrow morning. On the dyno tonight the transfer case started screaming something awful.
3/1/11:
They got approval and a new transfer case has been ordered!
3/4/11:
WOOOOOOOOO! Actual cost to Mitsu after parts, fluid, labor, rental car, etc. > $4,000! So happy to have it back after nearly a full week. The dealer also got a brand new transmission approved and shipped to them "just in case" so that was pretty damn cool too! I kept the stock tranny since it's perfect, but I think that was awesome of the dealership to go above and beyond like that.
3/5/11:
It got fresh rear differential fluids today 
Diaqueen 90W LSD & Diamond ATF SP III
Also noted that after 4k miles these Hankooks are wearing very evenly even with my -2* camber up front.
3/12/11:
New exhaust manifold is installed! I'm just waiting for the dyno to open up to get it back on to see what the gains are (should be around 4pm).
Baseline from yesterday:
I made 342/360 last November when I got tuned, the only thing that changed was Magnaflow ---> Cobb catback:
Stock vs. ported:
Some self-porting (gasket-match) to the turbine housing:
Installed:
Dyno results are in...unfortunately they are less than impressive 
Charts coming soon.
I picked up 3whp but lost 3 wtq (peak). Above 6,800 RPM power is noticeably increased, but that's about it. Boost stayed the same, but AFR's did go a bit richer so more power will be had once it's leaned out a bit again. It also lost a bit of spool which seems odd, but Calvin (tuner) thinks he can get that back with MIVEC tuning.
Next up is the intake manifold and throttle body, might do these tomorrow and see if I can get it for a retune sometime this week or next weekend.
November tune vs. ported manifold run (for some reason the dyno database won't show my AFR from the pre-manifold baseline, but at the time we compared it vs. the November tune and it was nearly identical):
Nice read!
