1 - IMHO that is a bit over-priced considering intercooled kits to do Grand Prixs are like in the $3900-$4500 range. DIY brings that down to around $2200-$2500, if you can believe that.
2 - That is THEORY. No one has stepped up and said that they are offering anything for any price... yet. All those amazing pics that SC2150 showed us are all rear wheel drive vehicles, I believe (Camaros, Caddys, etc...).
The front wheel drive is no different with the turbo, and were doing a 2014 right now that is AWD.
The cost comes down to we use the Borg Warner EFR turbo...the most technologically advanced turbo system in the world currently and the turbo alone is nearly $2000. You can get a $150-$250 ebay cheapo, but when they come apart the engine usually goes with it as they don't do well ingesting the metal pieces.
So yes, you can find complete turbo kits online for even under $2k total....but you have a china BOV, waste gates, etc. so you get what you pay for.
Add just a few of the parts used in the systems I do:
Turbo: $1800-$2000 plus (same turbo the Indy cars most use the past 3 years)
BOV: $250 plus
And all hot side pipes are mandrel bent stainless (not exhaust shop soft steel). All cold side is mandrel bent aluminum. The tig welding and fab work alone takes 40-50 hours....
The wideband is $350 plus, Boost gauge $100-$150
Were using all top quality parts that can easily be substituted for cheap china stuff if that's the route someone wants to go, but we wont scrimp at the expense of longevity and the engine.
We get a steady stream of blown up cobbled together systems to redo correctly and replace engines in. Turbo charging a car you value is not a place to scrimp and cheap out on.
As far as FWD, we turbo charge most any vehicle as long as we can tune it......just very few FWD GM owners stepping up.
But yes, someone with the skill and time and fab equipment could do their own in the $2000-$3000 range with cheap parts for sure, and just searching the internet I see some pretty dang good examples of DIY builds that do last and make good power. All in the persons ability.
Same with an engine repair done by someone themselves may cost $1000 or less (depending on the repair) where a dealer may charge $6-8-$10 k for the same thing.
So correct, no specific kit for these yet as the demand would have to be there to invest the amount of $ and resources for jigs, etc.
The ones I do are all custom one off for the non-mainstream systems.
