Well, a couple things have changed.
Due to the stock injectors giving me problems (leaking/hard-as-a-rock o-rings, and I believe one or two are clogged leading to a some cylinders being rich and others lean) I've gone ahead and installed:
- ID 725cc injectors
- VF28 out of the V5 clip
- Koyo radiator with WRX fans
- Retrofitted GR TMIC
From there I took it to Mann Engineering who had Bill come out from Delicious Tuning (skywalker on here) to tune it.
On an ECUTEK dyno I'm making 232hp and 210tq. According to Bill and Gary from Mann, that's about 20hp less than a comparable (2004/2005 non-AVCS) STI. That means I'm making 92% of the power of an STI with only 80% of the displacement, not bad.
I am seeing the turbo take a while to come on full boost and it sounds like that's caused by the stock USDM up pipe and down pipe. I'll be swapping those out for the JDM counterparts hopefully within 6 months, I just need a break for a little bit to focus on other projects.
Side note: The ebay special front strut bar doesn't really clear the GR TMIC - it rattles when at the right RPM. I've removed it and will be buying a GC8 carbon front strut bar as it looks like it'll clear much better.
