Let's see...VNT15/15 is gen1, GTB is 2nd gen...I like the idea of the GTD1752VRK for a lightly modded BEW. I like the quick spool of the BV39 but it is still boosting properly...
For the Gottuned stuff, I like that they have tied it all together, and among other things shortened the outlet spigot. It is a moderate upcharge, and the most troublesome bit seems to be the inlet hook up.
Then an ALH IC, a 1.8T pancake, and something to do away with the rest of the BEW clip on stuff. Not a weekend project for me...but I can always drive the Cummins whilst waiting for some bits to arrive.
cheers,
Douglas
