Here's the ones I know of....
- 89 rear-end is Torsen (that year/model only)
- there's a different wastegate that was used on later models, I'm not
sure of cutover year (see note below)
- the 180hp version started in 1988 but see note below
Note:
It's a good idea to look at the month/year of manufacture of your car. A
1988 could have been made as early as say 4/87 and may have 1987 features
even though it got an MSO for 1988 here in the US.
