I just got done this weekend pulling my motor out of my STI after 124,000 miles. The motor was super strong with 149-150 PSI of compression on all cylinders. The car was making 380 AWHP but I wanted more and I didnt want to blow the stock motor. So I had a motor built. I should be putting the new one in once a few little nick nack parts come in that I ordered. My new motor is made up of the following: New Track series block 09 STI Crank Pauter Rods CP Pistons, Coated Supertech Stainless and Inconel Valves and Springs, Complete Race Ported and Polished Heads by HeadGames ARP Everything with Head Studs Tigwerks Oil Pick Up Tigwerks -AN Turbo Drain Return on Block Fuildampr Dampner New STI Oil Pump Killer B Windage Tray. New Water Pump New Water Neck New Cam Pulleys New Cosworth Timing Belt New STI Red Intake Top Feed TGV Deletes Kelford Cams 272/272 Cosworth Gaskets Cosworth Timing Belt Guide Cometic Head Gaskets The clutch is a ACT 6 Puck with ACT lightened Flywheel.

Congrats on the build looks pretty sweet. A few things, I would reconsider those cams, they are a little large for that turbo. The second thing is the JDM 12mm oil pumps tend to fall off and lose pressure over 6000rpms. I would suggest the normal 11mm STI pump. Who built the engine? Matt
The JDM pump was actually changed out I just copied and pasted some stuff so my mistake there. About the turbo I'm actually using a GTX35R on this motor the aps was on the old motor. Another mistake by me. A friend of mine did the build he owns a machine shop in tenn. ICE motorsports.
Well I axed all the side feed crap for top feed and ID2000's and I axed all the stock location turbo crap for a GTX35r and a custom Tigwerks rotated kit with a custom Tigwerks FMIC and turbo inlet. I'm also getting headers from him and scrapping the gruppe-s headers I have now.
The Tigwerks stuff is awesome, Kelly does a really nice job. I'm considering having him build a kit for my car.
Finally got the motor in. Still figuring things out like where to route and mount fuel stuff. Still waiting on FMIC, Headers to be finish being built. This is where I'm at as of today. Here is the compressor housing after being machined for the V-band Here are a few pics of a few weeks ago
Headers, Uppipe, Downpipe, and Dump tube arrived today. Still waiting on delivery on Turbo, FMIC, Coolant tank, V-band clamps, Turbo inlet Sorry for the crappy iPhone pics
Go ahead and take that Grimspeed AOS back off. It doesn't flow enough air for a big turbo setup. In my experience they create extra crankcase pressure which prevents the turbo from draining and causes it to push oil out the seals. You are going to need something more like the Crawford or Moroso. I really dig your build by the way. Looking forward to seeing what kind of power it makes.
Very nice build. I could be wrong but I won't be surprised if you have issues with the MAF being inconsistant because it's too close to the inlet of the turbo. There should be at least 2 bends or 1 good bend between the turbo and the MAF.
He's really just using it for startup/break-in. We're switching over to SD after that.. Looks great Ryan- idc what that idiot Reed saysssh: lol
Thanks for the info on the Grimmspeed. The MAF is only there for start up and break-in. Car will be tuned on Speed density after that.
Stock ECM. After talking to several tuners including Doug. All said nothing but stock was needed. I was going to purchased a AEM but was told it was not needed. h23bb2 will be doing the tuning. It may make a trip up to TopSpeed at some point.
So you will be using Open Source? Digging this build. Tigwerks makes some great stuff from what I have read.
Steps left to complete before the first start up 1. Connect (1) coolant tank hose (waiting on hose will be here Thursday) 2. Connect (1) vacuum hose to EBCS (waiting on fitting and hose will be here Friday) 3. Fill coolant system with coolant 4. Hook up battery 5. Get start up tune uploaded to ECM In the next few weeks I will change out the Grimmspeed AOS for a Crawford as advised.
Well she is alive! She wasn't starting at first but after figuring out that the fuel feed and return lines were reversed thanks to this thread http://www.iwsti.com/forums/2-5-liter-litre-factory-motor/234218-04-sti-fuel-lines-what-what.html . That thread said the feed was on top well not on my car, its the opposite of what it says in the thread so I had it wrong. Once I had the lines switch all was good. I have a few things to button up before I can drive her to work and start putting some break in miles on her but so far so good.
You might be able to get the tank through Josh@ImportImage, he carries Tigwerks products just not listed on the website
Yes Tigwerks has been great to me. I have been very happy with everything he built for me! As with anything custom it takes time to build. You can contact Tigwerks on his FB and also view some of his prior builds http://www.facebook.com/Tigwerks
Car sounded good once it actually started. lol Let me know what day works best for you and I'll swing by
Hear is a quick video of it just starting up. The 2k idle was recommend for the first 10 minutes by builder. More work still needs to be done of course. Unfortunately I have to do things in steps because I don't have money trees growing. http://www.youtube.com/watch?v=YytdGEDp1hU&feature=youtu.be
Well its now on speed density and running good on 93, now time to get the rest of te break in miles done and switch to E85. It now has almost 100 miles on it
