Who has done a 540 Manual Conversion

[bmw540]

Hello I am wanting to do a manual conversion to my 540iA and was wondering if any one out there has done one.

Need advice...

[BillionPa]

no... but the only advice i can give you is dont cheap out on parts!... oh you will need new halfshafts, might as well get new rear wheel bearings if you havent done so yet.... and throw in an LSD or Quaife diff @ 3.25 ratio while you are messing around down there.

the 540 has serious tourque and power.Its why the M5 and 540 share the large case diff and gearbox and is the reason the 540 and M5 are heavier than the 535.My indy reckons the gearbox is twice the weight of a 535 gearbox!

SEARCH. I hope you have a lot of money.

Yep, you'd know once you have to pull one out. Most of that would be as the 540 auto is also a 6 speed (oftentimes). Not sure about the manual- is it a g280?

Weird piece of trivia for ya: Eibach specifies the same springs for both cars- and lists the same 'overall drop' when installed. The tranny in the 540 weighs more, the engine less but i guess they position it to balance out with the additional diff weight. Ask me how I know- I have factory 540 springs on my 535, and they work just fine. (BMW parts lists spec different ones though)...

Hmmm. weird.

Ive been looking into it and dont have any hard figures yest, but I think it could easily be done for about 2 grand.
Ive found a couple trannies from e39 540's for $1000.
Either a dont car or sourced parts for the pedal buckets master/ slave etc for about $500.
Used D-shaft for probly $200.
-Clutch kit could range from $300-$1000 based on what you want to spend.
Of course this is not taking into account labor as Id be doing the work myself, that would add substantial cost in the event you have to outsource the work.

JohnTee540 had his done a few months back.

It's been done for $3000... if you do the work yourself, you may save $1000.. it's a lot of work for a DIY mechanic though... a pro is worth every penny

I done it 4 months ago but I used the 530 manual tranny which come 5 speed manual, everything was great exept the shaft I had to do some work on it, but I didn't change the flywheel, and the clutch kit coz the last is 50% of tis life but I ordered a new clutch kit and flywheel for the 540 and not the 530 tranny and it will work just fine.

diff. didn't change it and happy with it with 2.93 non lsd. but not happy for the speedy highway drive coz i tried at 200 km and the RPM was at 5500, so if I upgraded the diff. it wanna be more than the rate.

from stop to 100 km was very fast I didn't try to check time by # but its really great.


this is what I did


it costs my the tranny with all needed parts 1000 US$ imported from Lebanon to Dubai.

thanx

M5 will be a G280 as mentioned above. I have a G290 which is even stonger than the M5's G280, and it weighs pretty much in the same ballpark as a 535i G260 (~50kgs). The box'es are all pretty similar size and weight wise.
