I have helped build some other race cars, and have a friend with a machine shop and much more experience helping, but neither of us have built a BMW before, and I was hoping for some pointers to help avoid some headaches. Nothing big time, just things like what do you do about thermostats? Will I need a restrictor plate if I toss it? How do LSD dependability compare to open Difs? What kind of oiling problems do you have? Will I need an accumulator for certain or will a scraper suffice? What kind of range should I shoot for when I build camber plates?
That should be plenty to get a discussion started, and sorry if this has been covered elsewhere but I couldn't find it in search.
Thanks in advance for your help.
Gibson,
Welcome.
First,
If your plans are to build a car and get into this venture go for safety first.
Second, a BMW is a pretty good starting point.
Third, spend your money on suspension, tires and brakes. Leave the engine alone. A diff is a GREAT purchase for a BMW, depending on the ratio it will do more for you than an engine build with a stock ratio will. A stock LSD is almost bullett proof. You can get into those other things later. Is it an e30 or e36? Both are ITS not ITA. Don't lower it if it is an e30 the roll centers go below the race surface and handling goes away quick. Close to stock ride height is about right.
Hope that quick post helps.
Oh yeah...ask me how I know those things........
