89 Carrera 3.2L at 0.5Bar Boost

Hey guys, I'm still doing my research into how to properly and safely turbo an 89 carrera 3.2L at 0.5Bar.

My dilema now is to decide which turbo to go with. This is street only, limited highway so I probably want a turbo with around .70 AR that can spool up fairly quick around 2600 - 3000 RPM.

Options are:

1. K27-7200 or K27S - Around $1400 new including shipping, etc. Sounds like this is a good fit but may need more oil requirements? Would I need a scavenge tank and pump for this one? What is the inlet/outlet size on the compressor side? Rarly8?

2. Garrett GT3076R - Close to $2000 new. Looks like also nice fit, and may not have as much oil requirements, but all I can find are with 4" inlet at the compressor side. Any sources for these other than ebay?

3. Looks like Precision have some decent prices $600 - $800 for 0.6 or 0.7AR. However, oil requirements are unknown and compressor maps are not available. Anyone using these here? Which model should I be looking at?
