E46 B3s manual conversion?
So following my purchase of my b3s (004) she had her inspection and health check at BMR Performance. Needless to say that the Service was excellent and Barry was very helpful.
There are a couple of areas where work will be needed and one main area is the gearbox. Apparently there is likely some significant wear which likely would require a replacement of the box. Now I understand that this is the weakness of the car anyway.
Barry raised the prospect of a manual conversion. This really intrigues me as I do like 3 pedals and for a 3 series size car I think it suits the vehicle quite well. I don’t dislike the automatic but I do know that there is a significant performance difference between the manual and automatic. (The manual is faster).
I would be interested in your thoughts.

Whatever you decide I know BMR have done a few now with very happy customers and great reviews.
I am slightly alone I think in preferring mine as configured by Alpina and will do all I can to keep it that way.

Re: E46 B3s manual conversion?
Personally would get it done on a coupe saloon or touring..
As you say a weak part of the car and known to sap power! Mines a vert so suits the cruiser appeal! Interestingly the z4 roadster alpina is a manual but I would guess the chassis is stiffer then the older e46 roof chopped off design..so suits the car more..

I had the conversion carried out by BMR on my B3 Touring. I didnt mind the Auto but the manual suits the car and is more fun!

Re: E46 B3s manual conversion?
My B3S touring is manual 6 speed. Much better car. BMW UK fixed all cars as autos for some reason. Theres plenty of LHD manuals in europe though as they had the choice when new
Re: E46 B3s manual conversion?
I owned a 335i se in manual and that’s was the combo it needed.
If the B3s was available in manual I would’ve had one.
We only live once!
Not sure anyone can say they own a manual B3s - now that sounds special indeed.

Re: E46 B3s manual conversion?
Thank you for your comments! I bought an original Alpina Wooden Gear Knob so I think it's fair to say I have decided
Now I cannot wait to get it sorted!

Re: E46 B3s manual conversion?
I wouldnt hesitate if its the way you want to drive it, and if the current auto box is on its last legs there's the perfect excuse!
Also its nothing that cant be undone by yourself or a future owner.

Re: E46 B3s manual conversion?
I'd say do it, the engine is wasted strapped to an auto box. They rev really well. You'll notice all that extra low end torque the auto box saps aswell. I went 6 speed but you can go 5 speed like Elan. The 5 speed box is much cheaper way but the factory manuals were all 6 speed
I've got a quaife in mine. I'd say also an LSD helps too.

Re: E46 B3s manual conversion?
I’m a fan of keeping cars as stock as possible with “tasteful” upgrades suiting the character of the car. I can therefore justify both the LSD and the manual conversion. The latter, however, only with the six speed, because that’s how it came from the factory.
Ps. Re Tasteful I accept depends very much on the car; my sunset orange m2 is soon getting a GTS Bonnet (body colour sprayed) and carbon splitters and spoiler. I think it works on the m2 because it’s an angry machine. The only exterior mod the b3s is getting will be the deko set.

Are the 6 speed boxes m3/z4m parts?

Re: E46 B3s manual conversion?
yes, the late 330i's also used the same box. If you can find someone breaking a 6 speed 330i this is by far the easiest way
I've got a converted SMG e46 m3 box and a custom propshaft as the B3S uses a 330d prop. So my prop is half M3 half 330d. Some 3.3 cars also use a large case diesel diff as well off a 330d to keep you on your toes!
B3S seems to use a medium case diff which is wierd as they make more power than a 3.3!
