Has anybody worked on the m10 enough to deduct what internals are weak other than the head gasket for example ?
I am picking up an extra complete m10 in about a week or so and will start with sending the head to the machine shop for clean up new guides/valve job. Then plan is to replace every gasket and seal and work from there. I would like to stay with the original block and not mix/match the block/head just for simplicity sake.
Metric Mechanic sells a sport version of the m10 head, and I am currently trying to weight the option of going NA and shooting for about 160-170hp but most likely it will cost just as much as to turbo the engine properly. I am looking at whats available for the m10 on http://www.kormanfastbmw.com/e30engin.htm
I would like to hear exactly what area(s) need extra attention for it to be reliable at let's say about 275hp at the crank on 91. Ideally I would need to size the turbo correctly to get good midrange tq, as I don't want to end up with peaky band or no power until 5krpm and usable only for 1-2k rpm range... I don't believe I'll need more power but would like it to be reliable 24/7 pushing atleast that much. I am pretty hard on the car(s) and basically want to do it once, right. I figure injectors will also need to be replaced, along with adjustable fuel pressure regulator and most likely aftermarket ignition system with fuel and spark controlled by megasquirt. Most likely fuel tank/pump(s) will also be replaced with a cell as needed.
Goal is #1 for it to be reliable and #2 fast enough for HPDE events. 100hp is just not cutting it no matter how much grip the car's got.
Thanks.
