BMW M51 questions from California
BMW M51 questions from California
Easy power is mechanical pump from the 324-diesel (all 325/525td and tds are electronic). Then the normal, exhaust manifold, turbo intercooler and so on... You can run about 350hp, just keep track of the old EGT.
To make MORE power, wait for our m51 rotor pump delete ---> om603 inline pump conversion.
BMW has it all worked out and almost everything fits across. The crank fits from m20 --> m50 and m51 and vice versa. Now the only crank with a longer stroke than the m51 is the m54b30 with 0,01mm longer stroke witch is nothing... But to make it a bit more interesting one can machine down a s50b32 crank to fit and get the volume up in the old m51d25 =) But that's not cheap easy power.
I hope you have some usable information here any how.

I can help you out with all your manual transmission, clutch, flywheel, intake and exhaust manifold issues.
The diesel gearbox is ZF S5D 320Z or ZF S5D 310Z, that's the same as 328 and M3 5spd. M50 flywheel will work, but M20 och M30 solid flywheels are better. M20 is only for a 228mm clutch (Sachs 618 pressure plate) so the M30 is better and allows for a 240mm clutch (Sachs 765 pressure plate).
