Yup, I've done this bolt-on conversion and it's very straight-forward
Interface a turbocharger to the factory heat exchangers via a J-Pipe, locating turbo on the side of the engine
Use a custom Motronic CHIP
Use a Wastegate preset to 0.5bar (non-intercooled), or 0.7bar (Intercooled)
Use a blow-off valve
If intercooled, fabricate the appropriate intake plumbing
Use a rising rate, boost sensitive fuel pressure regulator
No need for electric scavange pump, use gravity oil drain to lower cam cover
Plumb intake straight into the Air Flow Meter and away you go.
Mike, Juan and I all had the same system on our cars running 0.7bar at factory 9.5:1 Compression.
My engine has just been torn apart to go to stage 3 power levels and everything internally was in perfect condition (bearings, piston rings, valve guides etc).
If you have a Euro spec 10.5:1 Carrera Engine, you have no option but to open her up to lower C/R, but for the US spec model, it can be a bolt-on conversion.
U need the right CHIP though!
Hope this helps!
