ive heard of
1.9L
2.2L T\D
2.3L
2.6L
2.8L GM V-6
this engine could be replaced with a GM 3.1 or 3.4 V-62.8 T\D (over seas)
above are all GEN1 engines.....
3.1L T\D (over seas) as well as some ECM controlled common rail engines we never got3.2L sohc and dohc V-6 models GEN2, also a late model thats only one of the two....
and the direct injected 3.5L V-6 gas engine GEN3 only.
the only other one ive heard of, was a proto type (
that never made it to sales), it was
a 3.5L V-6 made as a V-8 back pistons had over heating issues thus it was scratched.
as to 4.3L
GM V-6 swap, or a typo
