Final Dyno Sheet:
How fast are you doing the downshift? 4th gear was revised multiple times until 1998 to fix this issue. Synchro clips can fall out, synchros can wear. Most likely you're looking at a new transmission unfortunately. If you need to limp it until then double clutch downshifts into 4th.
Sorry I was being harsh there, but am I wrong? You can buy a M340i easily, and there's loads available second hand. A lot more workshops modifying them as well. How about getting parts for them?
Don't get me wrong, I'd love a 400R, even a 4cyl (I looked at a few V36s before buying my shitbox BMW). Sadly Infiniti died in Aus and we're stuck with importing them as niche vehicles.
