hate to tag along but i have a m10 and am doing the 2l bottom end conversion, have another block and crank and am now working on the pistons, need a set of m10 2l pistons not flat top or dish, any ideas.

The 316 and 318 are same blobk crank pistons etc. but its the injecton or carbs that alter the power, esstially its like modern engine where you spec what PS you want, its all the same stuff just with a different mapping on their ECU's,

just bought another m10b18 engine mostly complete but in bits, also have a m10b20 crank and the 1.8 head has bigger valves and flowed, i want to put the 2.0 crank in the 1.8 and make a stroker, however not sure either what con rods to use or what pistons to use. have seen that you can machine the m1...

ive got an m10 engine with a fuel pump relay that's becoming a real issue, its getting worse. the relay seems to be making good contact with the holder pins but will not prime sometimes, just pop it out and in with ignition on and it will prime fine and run fine, but this is becoming an every time s...

The M10 DOES NOT suffer from the worn top end issues that plague old M40s BUT there are plenty of other things that can cause similar issues :( First thing I would check is ignition timing,not necessarily because it will cure your problem, BUT because it will be incorrect ! It should be 30 degrees ...

wow thanks for all the help, yep definitely not the cam had a good look with a mechanic, planning to do the ignition timing soon so maybe that's it, not of the ignition hardware seems to be faulty and is all in good condition. i had a thought that it may be the ecu playing up at high revs any ideas ...

had a look and it dosent have that, had a good look at cams aswell and they dont look too bad, maybe its not that afterall

also if the cams are wearing what should i be looking for, and what price bracket are we talking for fixing it.

i would never have considered that as it is so immediate at 4200 rpm, it's an 1984 Baur TC 318i, cranking is 3to4 turns to start and idle was roughish until new plugs and injector cleaner helped it. is pulling really well, torquey and smooth until that magic number. it has done 135k but had a lot of...

i have an m10 318i that is pulling really well up until about 4000rpm then it feels like I've hit an engine limiter, it shakes and rumbles and looses power, i can rev it past it but it doesn't seem to want to, any ideas. has had a recent service with usual maintenance issues fixed, we changed the pl...
