I think I've cracked the VF38 problem on the JDM/ADM GT's..
After months of reading and research I can tell you all the VF44 and the VF47 are direct bolt ons, but they are just as expensive, and no bigger, than the VF38. They do have the same compressor and turbine housing though.
What I've discovered though (and it's a bit cheap and nasty..but do-able)... is that Kinugawa can match up a TD05H twinscroll turbine housing with a MY08/GH8+ TD05H compressor housing...
Now.. you need a TD05H DP bellhousing such as..
You have a TD05H-16G, 18G, 20G on a twinscroll, equal length header and up, with a modified down pipe. Don't even have to change the intercooler.
That's the closest I've found for a 'bolt on' upgrade for the 2.0L JDM/ADM Legacy/Liberty from a VF38.
I'll be trying this concept out after xmas. Should cost about $1100 + getting the flange welded on the down pipe, above the cat.
How bout that?!
