    i have the 4.10 with an s52/zf and its a nitemare. Im scavenging the JY looking for a 2.93. i have plans for boost though. 3.25 would be sweet with the 260

      Actually the 240 has longer upper gears (not by much) i had a 4.10lsd with my g240 and wasn't impressed. Switched down to a 3.73lsd and it's a much more civilized gear, and still plenty fun.

        started out with a 4.10/G260/M50TU. Fun, but annoying at the same time. too much shifting, but the car accellerated like a fuckin rocketship. swapped to a 3.73, better mileage, not as much fun. Now have ZF320 and 2.93. civilized, good mileage and can break loose when I WANT to, as opposed to ALL THE TIME.
        I saved 15% on my Bimmer parts by switching to ...

          hey man, come take a ride in my car sometime. I have a m50/g260 with 3.25 rear end.

          I had a 3.73, which was way more fun, but was bad for highway driving. I swapped to a 2.93 for a little bit, pretty boring. The 3.25 with the m50/g260 is almost exactly the same as a 3.73 with m20/g250, just perfect for everyday drive-ability.

          the 2.93 is going to get you great gas mileage, but not be very torquey. i guess it depends on how much highway driving you do. if you can find a 3.25 i would recommend that.


            I will roll down soon!

              M50NV + G260 and a 2.93 LSD = 60MPH in 2nd gear.

              I just got my car together and I am in disbelief at how tall the gears are with this rear end in.

                    In looking at this thread again I find it funny,
                    You guys are saying that 60mph in second is bad.
                    My 318 with a 4.10LSD rear is 60mph in second, and pulls well through first and second.
                    Its also my daily, so the m50 will feel like a beast regardless, especially because it is turning into a 3.2l most likely.

                      What is 1st gear "crawling" traffic on any regular gearing, you're shifting between 1st, 2nd, and 3rd with a 4.10. Gets annoying QUICK. I can stayon 1st gear with my 2.79 in traffic with no problem and no annoyance.
                      I can't fucking stand doing that with tall gearing. Buzzing on the highway was annoying, but otherwise the gearing was great. What's the point of driving a manual if you don't want to shift it?

                          I enjoy zf 6 speed and 3.15-3.46 gearing.

                          any ratio between 3.15-3.46l is great for everything- gear 6 is overdrive for anti-buzzing and 1-5 are close spaced for fun. If you hate shifting in stop and go traffic you can just start in 2nd gear and use a 3.23 or 3.46 final

                            I have a 2.93 in my boosted E30 - works great. Still wish I had a 6th gear though for highway cruising.... Haha
