After more than a month of prep and a two day install marathon it is in and running. The goals for this project:
2. Keep stock airbox
3. Maintain most of the stock exhaust system (to keep car quiet)
4. Boost power for hills, passing, etc
5. Ultimate winter hot air kit
6. Keep it close to $1000 (not including my own labor)
7. 5 - 7 psi target
8. No Intercooler
First observations. Hesitation is gone even with little to no boost. At idle the turbo blows enough air to help the little engine perform better from the start. Seat of the pants dyno says there is a noticeable power increase, but I'm not sure how much boost I'm getting atm as the digital boost gauge still needs to be installed. That should happen tomorrow. I haven't pushed the car very hard or for very long since I need to know the boost levels. Atm the wastegate is set at the minimum setting (low psi), but I don;t even know if it is activating, and the BOV is also set at a low level. Again I haven't heard it it, so don't know if enough boost is being generated to activate it.
The idea for implementation came primarily from Drew (aka RHD Insight). he was initially going to provide me with the exhaust manifold adapter, a down pipe, and hotpipe. After waiting over a year I only got the manifold adapter. It had to be shortened to make room for the turbo, guessing this is a difference in RHD cars. I also rotated the turbo 45 degrees with the exhaust port angled down, his install was flat. I also tipped mine forward so it is on a level forward plane. It can be seen on the attached pic. Another departure from his design was use of a GT12 turbo, RHDInsight used a GT15. The GT12 is the smallest Turbo Garrett makes and is physically the same size as the GT15 with smaller turbines. My hope is that this turbo will be more responsive (less turbo lag).
Garrett GT12 - GT1241 - 130 HP ✈ Turbocharger Specs
Essentially a simple system with no intercooler and no 4th injector. To compensate the a12:1 FMU was installed to boost fuel pressure as boost increases. The turbo has an oil as well as coolant feeds. Both are hooked up and seem to be working properly.

I'll post more pictures and observations as they happen.
edit: 12:1 FMU verified suitable into the 5psi range
edit of edit: FMU is gone, replaced with 4th injector and injector controller ~$250
Also added dedicated wideband AF Ratio gauge ~$160
