Re: My 2005 WRX STi - built motor, dom3, meth, fmic, plus 4 other subarus
An update for anyone who's interested, the car is up and running. I trailered it up to Buffalo to have the break-in tune done at the end of July and have been working out a few kinks since then. Overall the car runs really well, I've put about 1500 miles on it since first start, although I'm still on a break in tune with low timing, electronically limited to 5000 RPM's and wastegate pressure. I'm driving it back up to Buffalo in a few weeks to get the 93 octane power tune done. I wanted to do e85 this year as well but the stations here are already on their lower ethanol transition blends and I want to have the tune done of the highest ethanol content possible so that will wait until next year. Cobb is supposedly releasing full flexfuel integration by the end of 2015 anyhow, which will be really convenient it that's the case.
Anyhow, here's some pictures (lighting was very harsh):
I'm already wishing I would have gone with a smaller turbo, but hopefully with the cams and head work I can run it out a bit further before power starts to drop off. For now I'm looking to change up the wheels and pick up a factory wingless trunk. We'll see.
Here's the full mod list from the engine build. I added some other things as well, some more suspension/chassis stuff and I'm sure I've forgotten some things. I tried to do it all right, but staying with a stock location turbo was a mistake. Rotated offers better fitment and faster spool, but it's all together now and I'll run it this way for a while.
