This is the basic idea, use a proven system. Cable to mechanical. This is a MR2 system.
(IMG:http://www.914world.com/bbs2/uploads_offsite/members.cox.net-3782-1306300496.1.jpg) (IMG:http://www.914world.com/bbs2/uploads_offsite/members.cox.net-3782-1306300497.2.jpg) (IMG:http://www.914world.com/bbs2/uploads_offsite/members.cox.net-3782-1306300498.3.jpg) I am running a 930 transmission and its shifting characteristics are well known, it's a heavy slow gear change motivated me to try something else. The system works much better than the straight cable. My "H" pattern is flipped as I need to install a new shifter unit which matches the back side. I've only driven the car one day and I love the direct feel. It feels like a modern transmission now, well real close for sure. The 930 transmission shifts like a tractor LOL. I'm going to remove the transmission brace tomorrow, sand down everything and put a fresh coat of paint all around. |

Cool fabrication, "Drive-ability." (IMG:style_emoticons/default/driving.gif) Is it written "tailshift," or "tail-shift" transmission? (IMG:style_emoticons/default/agree.gif) with "DB cooper" (good handle BTWT) Converting from tail to side shifting requires wasting some otherwise fine parts. Transmissions to make the conversion are not abundant, etc. I dealt with my 1972 "tailshifter" by tearing apart a perfectly good carpet and spending a lot of time replacing bushings and adjusting the linkage, but the performance is still pretty lame --even when compared to my '71 VW (albeit a 4 speed). (IMG:style_emoticons/default/hissyfit.gif) The problems with the worn ball and cage linkage in back remain unaddressed, and to my knowledge, unaddressable. Looking at the manufacture charts for years and models, the 1972 four-cylinder was the 914's biggest production run at @ 25K units (all from the top of my head so please forgive if those stats are inaccurate). Each one of those was a tail shifter. Anyhow, I've been thinking about this since I realized the difference between tail and side shifters (about 6 months ago) and although I am not an expert in any part of the automotive process, I've got a welder and a lathe and know how to use them. (IMG:style_emoticons/default/welder.gif) It would be fun to develop a fabrication procedure--though now that I've said it that sounds too ambitious for my skills. "Drive-ability", Those are nice photos, thank you for sharing them. (IMG:style_emoticons/default/pray.gif) Would your MR2 styled system be the best analog for a 901 tailshift conversion? Has anyone else done another kind of homemade cable shift conversion (I recall an older thread that used a heavy piece of plate steel under the car as a platform for various cable stops and pivots for a 901 cable shift conversion. but I can't find it, nor do I remember if it was applied to a side of tail shift car.) Like I tried to convey above, I'm a 914 novice, and know this has been tried, talked about and discussed at length. Having said that, it is my feeling, based on looking around the net, that it takes longer to find the parts to assemble the side-shift conversion and they are more expensive than they used to be. Am I mistaken about this. E.g., Im guessing it requires about $500 and a bit of looking around to accomplish the typical tail to side conversion -- starting from scratch -- moreover, after assembling it, you still need to go through a fairly laborious process to dial-in the linkage. My goal for this post in reply is that omeone who knows what they are talking about is inspired to pass along some more information or links about side and cable shift conversions for either the 901 or 930 transaxle. That would be much appreciated. Thanks again to "Drive-ablility." (IMG:style_emoticons/default/aktion035.gif) |
