I thought auto ZHPs were 3.64, and regular AT330s have a 3.38. On a 3.38 you still have to swap output flanges, just not the input.
Maybe a stupid question, but can you move all the innards from a non-330 into the 330 pumpkin as a workaround for the input flange swap?
Well I guess I have a flaw in my own plan! I'll have to swap output flanges then - luckily they just pop right over.
As far as swapping "innards," that would be more difficult than swapping the flange. I believe you'd have to swap the pinion in order to change the ratio, which I can only imagine is more involved than just changing the pinion flange. Such a swap would also require you to really know what you're doing when checking (and potentially having to change) preload/backlash post-swap.
Touché. Really I just need to decide if I want to dump $1k into a track mod for a car I don’t plan on tracking that much longer (I’m never going club race this car, which is ultimately what I want to do).
I know in the past people have sent a full diff to the vendor and they cleaned it, installed the lsd and did a rebuild on it, and shipped it back.
i never got to the track with the Touring, but i enjoyed the hell out of the LSD. and the 335i, making another 66hp and 90ft-lbs of torque, needs one even worse.... i can spin the summer tires through 2nd gear, the winters through 3rd gear. wheelspin in 3rd gear is a little unnerving.
Ah, I thought the 800 included the diff, I didn’t know you had to source a used one/remove your current one in order to have this done
