Conversion of 540i to M5?

Hi guys i'm new to BMW M series, i don't know much about the cars but i have a quick question- Is it possible to convert a 2001 BMW 540i to an M5, or are the upgrades of the M5 engine (other than those things that can be bought) totally different from that of the 540?

Thanks A Lot!

The M5 motor is based off the 540 block, and I think thats about it...
Not bolt on mods..
If thinking of doing this, sell the 540 and buy an M5 if you can.

I would say for the right amount of money anything is possible. However in the end, the VIN will still say 540. I don't think you would ever recover the money and time invested. It would be a better option to sell the 540 and buy a M5 if you want an M5. If you just want the body panel look that would be possible. However to get the drivetrain to match an M5 would be much more $$$.

Take a look at the internal engine differences between an M5 and a 540 in this link.

You could try, but it would end up costing more than just buying an M5 to start with.

The M5 is not a "bolt on" conversion of a 540i. The engine is highly modified, as are the tranny and rear end.

The dual exhaust of the M5 requires the removal of the spare tire well (this is why you don't see 540s with exhaust tips on the right side, even the ones converted to "M look").

That's really only the beginning. Suspension, special interior upgrades, body upgrades.

Why are you looking at this option? Do you already own the 540i?

The S62 is a far cry from the M62 motor.

e39 540i/6 vs. e39 M5 - What do you get for 3 X the $?

540i is a great car, then again a blown 540i is pretty darn sweet too. That being said, if youre going to invest al that time and money, just go for an M5 from the start. find a dealer with them on the pre-owned lot and hop in. You will understand immediately. I remember when I bought mine the sales associate didnt say a word during the test drive... The car speaks for itself.

thanks for all the help!

question though, why bolt-on a vf blower and call it a day?

Installing a VF supercharger would give you the performance to match up and exceed the stock M5 is what he was talking about.
