So I had an 85 535i blew the head gasket over time and just decided it was time to try out an e30 so I got an 85 325es and put a little money into it but I've decided that e30's arnt my style if you will, I love the cars but there not for me so I'm buying another 5 series. I have an 83 533i at the shop that needs the basics (timing belt, water pump, shifter bushings, coolant flush, crank sensor and break job) but the problem is that it won't rev over 3k and dosent have all the power, could it be just the crank sensor or something else?
