915 gearbox rant

Question here: am I the only one that hates the 915 gearbox with a passion? I have one in my '84 Carrera. Now before you say "oh, you just didn't set it up right", let me list the things done: Jwest shift tower, Wevo short shift kit, Wevo coupling, new OEM synchros on 1st and 2nd, fresh Kendall oil, relatively fresh shifter bushings, recent coupling adjustment. So I went the whole 9 yards. Shifts way better than I got but still far from good.

Now, I maybe spoiled by the modern gearboxes since I've owned nothing but manuals since 1998 including multiple NA Miatas, Integra GS-R, WRX and even a '72 Beetle. The latter is what got me into Porsches. The 4-speed box on the Beetle is a lot easier to live with. It doesn't require rev matching and only minor issue has been a bit of a grind on the first on a standstill but I can live with that. I won't mention others because the Miata and Integra boxes are in a whole different league compared to the 915. They're not even the same sport really. The only one that was just as crappy was the 901 in the '75 914 I owned for a few months a few years back.

Enter 915. That thing just seems to get into 2nd gear whenever it feels like it. Rev matching or not, even with a new synchro I can't get it in some of the time when not upshifting sequentially. 3-4-5 gears are somewhat acceptable providing some rev matching is happening but the first two are absolute horror. Even the first gear won't always engage despite a new synchro prompting my getting the horn from behind more than once.

I haven't driven a G50 car but I imagine it's a lot better. Have driven a 993TT and obviously that gearbox was working fine although the clutch was admittedly rather weird. Still it wasn't too bad and I learned to drive it smoothly quickly enough.

So I'm curious, any other owners who dislike 915 or is it just me?
