3-Series (E21, E30)Chat relating to the BMW 3-Series from 1975-1983 and 1984-1991 line. Specific models: BMW 315, BMW 316, BMW 318, BMW 318i, BMW 320/4, BMW 320i, BMW 320/6, BMW 323i, BMW 320i. E30 Family models include: BMW 325e, BMW 325i, BMW 325is, BMW 325ix.
Got an 86 325e. Transmission is removed to replace flywheel that lost it's crank position/timing sensor magnet pin. Will be replacing clutch. But, since I'm already halfway through the worst part of pulling the engine anyway, I'm considering going all the way. I've rebuilt more than a few motors out of domestic cars, this would be my first foreign, but I expect, mostly, "parts is parts" as they say. I've already talked to the shop where I usually get my machine work done and they gave me a warm fuzzy feeling about doing the work. Question is, are there any specific things I should keep in mind, tips and tricks to make the job easier/better. I'd appreciate any advice from anyone with experience. TIA.
shave off all eccess metal that you don't need. When i did mine, i shave everything, inside the intake, the center of the throttle body, the exhaust manifolds, anywhere that would restrict airflow. Shave the head, boost compression, i went 30thou, but you could go more if you wanted to. Have the whole head done, by a machine shop, cost me about 250, but it was better then new. Match all the gaskets to the openings, if the gasket doesn't cover the whole surface, shave the surface till it does. While your down there, strait pipe the exhuast. I put a hollowed out flowmaster right after the o2 sensor, then 2 1/2 inch pipe all the way back. It breaths like open headers and sounds pretty mean. I don't ever remember what else i did to the motor when we put it back together. The key is to make it breathe. These engines really need to breathe. My stock 325e is now faster then an E30is with just these simple things done. I'm pretty sure it's faster then my mom's e46 325 too. Close anyway.
