I wouldn't say that I've got extensive or in-depth knowledge of turbo engines, only in the testing of turbo's on that stand. And of that, I built the stand, I only have testing experience from helping those doing the actual testing as part of my responsibilities to developing the stand.
The car came to me with the turbo off of a 3.0L Audi in the trunk. I need to build an exhaust manifold for it that doesn't have the massive heat riser hole in the top of it. The plan for that manifold is to locate the appropriate place for the turbo to sit, terminate it in a turbo flange, and then build a head pipe with a matching turbo flange. I've already sourced both flanges and have surface ground them to be truly flat. I know that welding and use will warp them a little, but at least they're starting out really flat instead of just a piece of plate cut out to the right shape. If/when it gets the turbo I'll just build a new head pipe.
I want EFI, the over-all plan is for this car to be a DD and "date night" car. I've messed with carbs long enough, I want something different. Having driven both, the best tuned carb can only compete with EFI in drivability for a short while. Then you have to tune/tweak again because the seasons changed or you drove out of the tuned-for altitude or........ I want a driver, not an on-going project. I have of the latter in this:

Current engine is a 170 and that
will not change. Lots of people have tried to talk me into a 225. They're wasting their breath, and some seem bent on continuing to do so. Current engine has a very large oil leak that is somewhere around the oil pump. Which pretty much means that the engine has to come out to get to it. If I'm going to pull it I'm going fix everything else wrong with it too, so my other 170 is waiting it's turn in line at my local favored engine builder.
IF I can't get the moderate mileage and performance goals out of the / it will get an engine swap, but not to a 225 or a V8. It will get an OM-617 or a an OM-603 Merc turbo-diesel.
I like the manual. This isn't a drag car. If anything it's to be a very occasional auto-x car, but mostly a curvy roads & DD car.
