Best turbo depends on what you want to accomplish.For quick spool up you'd want a K14, for max boost a K03, there is also the K24 which I think is sort of between the two.The K14 spools quick but is limited to 18-20 lbs of boost, a K03 will take lots of boost but spool up ~1,000 RPM later.VNT on an IDI has been done by several, search for it. There is also a thread on Jack's forum http://vwdiesel.net/phpBB/viewtopic.php?t=8065
Probably a T3 haybayian.I want to buy a K14 if someone is selling
I find T3s big and laggy with stock fueling and a stock exhaust but as I've found out mine was rather worn so that may not be accurate
i thought it went K03, K14, then K24? and garrett (which most believe is superior) T2, and T3.
