  1. I will take the flywheel off your hands if you have no luck ;) went from a dual mass to a m20 lightened fly on m50 and was an unmistakeable difference, particularly on decel, e36 now has a dual mass and rev response is very very slow in comparison, i would suggest you have some other issue.


  2. I have both and a M52B28 and the M50 (325 non vanos) performs a lot better at high revs than both the m52's - the b25 and b28 both outperform the m50 lower in the rev range (but a 4.10 diff sorts that ha ha), you can make a few changes to all of them to acheive what ever it is you want to achieve.

    the M50 is 192bhp which is the same as the M52b28.

    A manual conversion is simply the best mod for any of these engines and in that form you will not be dissapointed by any of them. In my veiw deciding between them is like splitting hairs and is all down to your application.


  3. I had a similar issue with the camshaft sensor on the m52b28 similar symptoms but intermittent - the diagnostic machine found nothing when the car was going fine so I had to drive it straight to an auto electritian when it appeared and the diagnostic found a fault with the cam sensor - replaced at huge expense from BMW and problem all sorted.


  4. if the smoke is blue then it is oil burning, could be valve seals but if it is heaps of smoke continuously I would suspect other problems, the only way to check I guess is to pull the head off. You will then know if the gasket is a problem and you can then turn the engine over by hand and get a feel for what else is going on.


  5. Normally there is a little metal tag that is attached to the rear cover by one of the main bolts, these are normally pretty rusty but will have the ratio stamped on them, the other way is to mark the out put shaft and the diff case then turn the drive shaft and count how many turns of the out put shaft to one turn of the drive shaft - crude but will get you pretty close, its easy to tell the diff from a 4.1 to a 3.46 for instance.


  6. do you mean top or bottom end? bottom end relates to bearings , rods, crank , pistons etc and if it is smoking as bad as you say then I would say you have some issues here. A blown head gasket could show some of the following symptoms, water in oil or vice versa, loss of power, poor idle, steam from exhaust, obvious over heating. From the symptoms you describe I would suggest that your issue is a bottom end one, this will cause overheating also as if something is crook friction will normally increase burning oil and raising temps. Is your coolant just rusty brown?

    I think a head gasket would be the least of your worries from the sounds of it, I would drain the oil and have a look for either water in it or bits of your engine!!, flush your cooling system until the water is clean, replace the oil with some cheap stuff, go for a drive then inspect both again, will give you a better picture of what is going on. Any strange knocking noises from the engine? Compresssion test will also give you some info.

    Good luck


  7. gidday Gus, Nope didn't try for long though, I decided to race it in the winter series, This car just goes and goes - ultra reliable and just keeps getting quicker, finished third overall for the series, no race wins but a couple of very close seconds, feilds of up to 30 cars (some of those were hq's though haha) found myself in the fastest half dozen all series. For someone wanting a great car that could still benefit from a bit of cash spent on it this is perfect.

    I am looking for a sunday drive now that I can share with the family - so will consider trades (240z, 2002tii ,m325 etc etc)

    price also ono.

    Cheers

  9. A press is fine if you can get it to your subframe or the other way round I just burnt mine out with a gas torch, if you replace with poly items or similar then you often do not need to press them in I didn't with the powerflex ones, it is a whole lot easier to drop the whole frame diff etc included - it is a good few hours to do the job by yourself with a hoist though, i couldn't get the bloody subframe to drop out took a bit to work it loose.


  10. Had the same issue withthe racecar, hex bolts had come loose, tightened them up - noise still there and really apparent going around left hand corners - turned out to be the CV it was trashed, car is lowered somewhat and the angle on the half shafts is probably contributory. I would still pull of the CV boot and have a look see, you will see if it is worn.
