I bought the car brand new in March of 2007. I have a long list of stuff I have done, so bear with me as I build this and post all ECU logs (for tuning purposes), pics and stuff. This will be made so people can get an idea of what the stock limits are on an 07 STI and how to build it up after you break it.

Update:

Mods when engine went(316 WHP, 352 WTQ):

APS 65MM CAI
Full TBE (Catless Agency Power D/P with SPT 3inch catback)
My modified XPT Stage 2 mapping (the failure was due to previous abuse and a casting flaw in the #3 piston compression ringland, not the map)
LC1 perm WB w/ Red BD gauge
Gaugepod.com a pillar pod
Autometer boost gauge

Done building engine (on breakin tune):

Homebrew block with forged and ceramic coated CP pistons
TD05 20G 8CM^2
08 STI TMIC
Snow performance meth kit (need to get safe injection still, but I have a safegaurd solenoid for low level indicator), plan on getting the digital controller and safeinjection from Labonte
750CC DW injectors (balanced well)
WB Fuel pump
Gates timing belt
Samco turbo inlet pipe
Samco MAF tube
Samco radiator hoses
Samco IC hoses
TXS dual catch cans
Grainger BCS
TBolt clamps
TGV weldless deletes (Weldless TGV Delete Kit - '07+)
Smog pump delete (Subaru WRX/STI Air Pump Delete - Driver Side Block-Off Plate)

TODO:

Tune it w/ Meth on.

NICE CAR GABE

good luck on your rebuild man, i went threw the same thing but at 1100 miles and no help from SOA

btw i will be contacting you to get a good idea of what you are going to run caue we almost have the same setup

[valleySTI]

btw that pic with the piston brings back alot a memories

[gabedude]

I updated my build list.

I remember about your STI failing.

yeah

but i am thinking of going your route, just need the turbo and injectors, but i will get in touch soon so i can get some info on how to run the meth

Good luck with you new build. I never heard how your first one went but my symapthys go out to you.

Good luck with your build...I am particularly interested to see how the 08 STI intercooler performs for you.
Do you think you will have issues maxing out the stock MAF with the APS 65mm? Any thoughts of going with the 70mm instead?

sooooo, why did the 3rd piston ringland broke ???
lean air mixture ?, detonation ?, knocking ???

Take a look at the pic closely. (bubble - casting defect)

Thanks, I am excited to see how well it performs.

The stock MAF goes up to 400+ G/S flow and at 280-290 G/S I get 310-320 WHP. If I run out of MAF I can just halve the load values (and everything else that has to do with the MAF sensor) to get 2X the airflow measurements but at the sacrifice of table resolution. Scaling an APS 70MM is a PITA. I have done a few and by no means is it any fun as it is non linear (you have to rescale every cel in the MAF table which is much harder that upgrading injectors and changing the injector scaler and dead times / (lower portion of the MAF for non stock intakes which throw off the MAF because of bends in the tubing)).

I suppose if I do go over 400 G/S I will be getting the larger one and doing the work to rescale the MAF (upper end).

I have a whole bunch of pics to add and build instructions. I am going very slow to do it right.

[gabedude]

So I broke one ring after realizing I had the gaps on one side on the piston skirt (Helps to read the manual) and I broke a ring trying to put a piston back in. Had to order a whole new set (4) of rings, so I have 3 unopened bags. Anyone want them?

Next is to finish assembling the engine (manifold, etc) and drop it in. I have to wait till the 1st to buy a hoist so it is going to be ready to drop in then.

The Gate's timing belt has great markings and was easy to install (after I figured out I had to turn the LH side cams to get them to line up). Engine turns fine, no hitting of valves against pistons (that is always good). I am getting excited now.

What type of gates timing belt are you using? i know they make 2 types the regular black belt or the blue one that has kevalar lining in it so it won't break, and stretch as much.

[gabedude]

It is the Blue one.
