The 6-Series was introduced by BMW in 1976 two models, the 630 CS and the 633 CSi. With 3.0 L inline six cylinder engines and coach work by Karman these were stunningly impressive cars. As they aged the coach work was moved in-house and the engines grew to 3.2 L but stayed with only six cylinders. This was odd because the competition at the time from Porsche (the front engined 928), Mercedes-Benz and Jaguar all had big V 8s under their hoods.
Over the years there were various refinements to the 6-Series, including the introduction of a more powerful model, the 635 CSi, in 1978. While engines changed some most of the changes over the life of this series included luxury and cosmetic upgrades. The 6-Series was the flagship of BMW's line from its introduction in 1976 until it was replaced in 1989.
When Nate got his 1980 633 CSi he found that the engine ran too hot. This was a complaint that plagued this model throughout its life. These engines would also run a bit rough after a cold start and would seem to be reluctant to go until they warmed up. Even warm they tended to run fast with what many thought were high RPMs at idle.
Nate found an easy solution since he was using his 633 to drive around in. What he did was find a 3.5 L 7-Series engine and drop it in. He said that it can still run a little hot when idling for a while but otherwise has been a great addition to his car.
The former police detective said that once he was driving along the highway in another state and realized he was going perhaps a little over the speed limit. As he slowed back to the legal speed he happened to come across a state highway patrol officer running radar. Nate missed a possible ticket though he would neither confirm nor deny that his car might have been traveling 138 miles per hour. Not bad for a cop's car.
