I have had an S&S system in my '84 (1.9L) for a couple of months now.  Only
problem that I have had was caused by my negligence in not assuring my
mechanic had his Wheaties the day he installed the new system resulting in
one of the bolts coming loose.  With regard to distance to transaxle
housing, one would hope that mass of the housing and lubricant inside would
minimize effects of the close pipe.
