[s-cars] Turbo....anyone have a loaner or one for cheap?

[Mike Miller]

Following on what Dave said, if you DO get boost, it could be the WGFV. 
That was my problem in 1996 when I went thru this.

With the previously mentioned vicegrips, you can determine if the turbo is bad in about 1 minute.  If you clamp that line, you will immediately enable the turbo to develop about 15psi with no possibility of engine management interference.  You will either get boost or you won't... period.  If you do not get boost, either you turbo or your wastegate is shot.
