No dude, you getting me wrong. Not looking for an argument, just trying to understand how - with the amount of work involved - it is possible for such a job to be done for R5k.
That's 10-12hrs bud, I cannot understand how someone can do that much work in so little time while being able to stand behind their work? I mean, you looking at around 3 hours just torq'ing all the rod bolts (it has to be done 3 times using stock BMW rods, less time if you using ARP bolts). Then there's stripping all the bits to actually be able to remove the oil pan. And while you putting it back, you want everything to be cleaned as well while you in there and not leave it in the dirty state you found it in.
Yes, you can do it in 2 days - the dealers rebuild engines in that time - but that is a standard mech simply changing bearings and holding fingers that there's no issues. On a Blueprinted motor there's a lot more to consider as opposed to simply slapping replacement bearings in.
Like I said, not trying to argue but trying to understand what it is you getting for your R5k's worth of labour.
