Selector rod differences

[thatphysicsguy]

Hey all,
I'm going to be doing a 5speed swap on my m20b25 pretty soon and I have the ability to make my own dssr. I have an old regular selector rod, but since I don't really have a car to do any test fitting on until I do the swap, I was wondering if anyone has tried to make their own DSSR and what kind of fitment troubles (if any) they encountered.

I have a photo for reference from uuc:


but the regular selector rod they have looks a bit different than the one I have(mine has two different sizes for the dowels. Also the fact that certain selector rods don't work with certain motor combos concerns me a bit.
I just don't want to blow $$$ on aluminum when I already have a pretty tight budget for this.

Any help or insight would be greatly appreciated. I might even make a couple extra to sell if there's any interest (I don't have the capacity to mass produce these, though).

I have a uuc dssr sitting in the garage....

In my opinion a DSSR is just another way to make your wallet lighter. It simply isn't needed.

Not needed, but it is an improvement. The difference between a UUC dssr and one you make in your garage for 10 bucks is negligible however.

I actually just finished taking measurements from a stock rod to mill a DSSR on the cheap. I think it will be pretty straightforward once you get spacing and measurements right

Yeah that's the big question I'm wondering. Because if some of the clearances are off, there will be bad shifter feel or interference.

I ground shims so I have the perfect amount of clearance between the dssr and the rose joint/shifter. No side to side slop and still freely rotating. Used shoulder bolts and nylocks to attach both ends of the dssr to eliminate any possible slop in the pins.

The UUC advertising cracks me up.

"double shear".

The early 2002 HAS just such a feature- and BMW figured
out it really didn't matter enough to spend all the effort on, so the later version is what
they've used ever since.

In my (not unlimited) experience with BMW's, the biggest advantage of the early 2002
shift linkage is that the bushings were spaced farther apart, and thus had less force on
them. This lead to less wear, less deformation, and slightly better shift feel.

Let's face it, how much twist do you REALLY put on that rod? How hard do you shove
it? How long do your aluminum 3-4 shift forks last?

Save your pennies for better speakers....
