Put her down for a week, did timing chain, oil pump chain, intercooler pipes (turner), diverter valve upgrade (GFB), replaced the turbo coolant and oil return lines, oil pan gasket, VCG, spark plugs, coil packs, and re-tuned the motor, and transmission, also put a  magnetic oil filter cap on it from Paradigm.

Experience: the timing chain wasn’t that difficult, if you have the mechanical knowledge go ahead and do it. It’s worth the time. I got the timing chain tool off of amazon (big no no in these subreddits😂) saved myself about $200 and the till worked great. No failures at any point. If you’re thinking about doing it, just stop procrastinating and get it done. My experience might differ slightly because I have access to a two post lift, and more than the average collection of tools, but as a BMW owner you should have most of the tools needed at your disposal anyways.

It took a week because I work in a shop and was just doing it a bit at a time when I had down time. No excessive hours were put in at any point. With the addition of the performance mods and the maintenance the fun little sport display on the I drive maxes out to the 320hp on the dial. Just wanted to share my experience because after the timing chain I feel like I own a new BMW again.

One week later…
