I just wanted to share my build off of my 2011 wrx. All of the work concerning the actual build has been done by IAG and i am more than happy with the outcome. IAG will be doing much more work for me in the very near future with my wrx.
The reason for my build was ultimately do to a negative result of low oil in my wrx that yielded very bad results to say the least .
Prior build history:
Prior to this build i was a simple stage 2 car running Cobb stage 2 (catted downpipe by perrin, AEM CAI and a nameless axle-back muffler delete set-up)
Quick recap of the "bad" moment:
Driving down I81 during the first snow and the car shuts off next to an 18 wheeler forcing me to pull off and wait for 2 1/2 hours for a tow back to my house.
The Build start history:
I was debating on what to do with the car and where to take it to. After calling multiple shops and much debate on the expenses that would soon take place i went with IAG. I went with IAG after talking with Drew and Rick over the course of a few days. I felt much more at ease after dealing with Drew and Rick from IAG and i was sold. I had the car towed to IAG after it sitting in my garage for over a week. Over the course of a few weeks/ a month i had gotten funds together to start the initial process of diagnosing and taking things apart. I knew that they were extremely busy at the shop. I basically had the car towed and let the guys have at it. I called very very few times as Drew and Rick were quick to call me with updates and new findings. As time went on, my parts list grew and grew as i kept adding on goodies to ensure a strong foundation for a proper build for future modifications. These decisions were based off of the excellent help and direction help of Rick.
The car ran low on oil with no real warning signs. I ended up spinning a rod bearing in cyl 2 and cyl 2 piston had a ringland that simply fell apart upon inspection, the rod was obviously bad as well.
The parts list for the build
GSC Stage 1 cams
No actual head work as of right now other than the cams, springs and retainers
Manley H Beam rods
Manley pistons 99.75mm
Cylinders obviously machined to fit the pistons
Heat treated crank
Walbo 255 pump
Perrin Catted DP
Nameless Axleback muff delete
IAG Un-equal length headers
Perrin Turbo inlet
Stock turbo (for now)
Tial 38mm EWG (external dump)
Killer B Pick-up system
ACT clutch heady duty modified street
Odds and ends:
Crawford Air/Oil separator
Air pump delete
All race bearings
After having the car tuned at IAG the results were not what i had expected. I was expecting numbers from 280-MAYbe 300 being as i am on stock turbo.
The numbers are as follows:
324awhp at 351 torque (uncorrected) pump gas
The car is very fun to drive! AND i am glad i went with a set of cams as they REALLY helped out a lot in reaching those numbers.
My next mods are as follows:
Bigger turbo and STI tranny swap. My next goal is to hopefully be around mid to high 400's with a bigger turbo (i was thinking the 3-xtr? open to suggestions)
Well, it is now September of 2015 and i have some new updates on the car.
I went with the following:
Perrin Front mount
invidia catless downpipe
We tried to use the top feed set-up, but for w/e reason, my car did not like that and was having drivability issues, so the top feeds went.
Below is the pic from the dyno
My next big mod will be the Aquamist set-up. Hopefully this will put me closer to getting to the mid 400awhp range i am ultimately shooting for. As for now, the car is fun and def pulls hard in the top end (especially when its cool out).
