Oil Pump Upgrade

Post by joe boston » Thu Mar 05, 2020 2:44 am

I was searching this forum but have not found any info on later M30 Oil Pumps from 82-89 if they can be retrofit on M90 engine 3.5L 1980 ?
Not sure if anyone here has any info, if they have upgraded to the newer Oil Pump with relief value...if so would the sprocket and timing chain match up..
any info is appreciated.
thanks Joe

Have a look here. This is set for my car (84/85), but plug in your own model. Shows ineterchangeability ... Id=11_0485

If still stuck, contact Carl Bennet at Korman Autoworks,
