Which 20vt motor is best??

[R. Mair]

I'm once again, in the early stages of planning my 20vt swap into an earlier
car. Due to an accident in my beloved 87 4kq, I'm using a 90 90q as the
platform for a turbo swap. I'm wondering the following... Which 20vt motor
is the best for this swap? I'm going to assume that the latest S4/S6 engine
(1995?) would be best, no? Funds are not an issue, I just want to make sure
that there isn't anything wrong with the later 20vt's or anything that would
prohibit a proper install into a 90q. Any advice would be appreciated!

PS. Any idea what the URL is for Nates 90qt page? I've been looking all over
for it.
