OK, I know the 914-6 came with a 914/01 transaxle that was of course a tail-shifter. I know the 4 cylinder cars came with a tail-shifter too, but not a 914/01.
What was the difference between the two other than the serial number? I have a non-six transaxle in my car and I believe I want to find an original six transaxle for my car and then have it rebuilt with the proper gearing for a 3.2 street driven car. I also want to upgrade to a nice shifter system to make driving more enjoyable. JWest shifter? I already know their shift linkage assemblies are no longer available. Should I then have the six transaxle converted to a side shifter? Should I just use all stock six shifting hardware, rods, etc. with the exception of the shifter assemble itself? Should it remain a tail shifter or would I be better served to convert to a side shifter? (I would keep the original tail shifter stuff just in case). I really don't have a clue but know that I want to do this right the first time and not regret spending $XXXX and then changing to a completely different system later. Thanks for any advice, suggestions and/or personal experience. Michael (IMG:style_emoticons/default/popcorn[1].gif) |

BTDT - it is simpler to just go buy a sideshifter
& don't worry about the gear ratios - you will just lose about 3-5 mph on the straight at Thunderhill by running a late sideshift - and I never could get over 100 there anyway, so it was irrelevant - you will need to also get the entire late shifter, rods, etc, and a adaptor bush for the firewall, (i have 2 sets if ya need one) AND - importantly - a special-made aft shift rod - GPR used to make & sell these, and I have had one in my car since it started racing in the early 90's; worst case - I successfully bent & twisted a stock late style aft rod a long time ago to make it fit around the exhaust, and I still have it in the shed - no work of art, but it worked regarding the oem sixer tailshifter - I had a lot of trouble with the puny lever that goes up into the trans - it ain't a very strong component, and more than once i found myself under the car manually shifting into 3rd so I could limp it home back in the '8o's LarryM OK, I know the 914-6 came with a 914/01 transaxle that was of course a tail-shifter.

Yea the 6 has a lower 5th gear, which translates to higher cooling fan speeds for the 2.0 6. I had a stock 4 cyl side shifter with my 3.0 and (for me anyway) the gearing was perfect.
I make conversion shift rods for 6 conversions, but it's not rocket scienct. There is a bend and angle to it that makes a difference from just a straight bar that some people have sold, and FWIW I made a bunch of shift rods for Dave at GPR back in the 90's. |

If you can get/borrow a copy of the Tramission rebuild video that Dr. Evil and I did, he shows the difference in the tail cone.

I agree with sixnotfour. you will regret keeping any remnants of tail shifter. I think a 3.2 would be hapier with taller -4 gearing
I would go side shifter with a jwest. the upgraded linkage joints have no play makes for nice positive shifting feel |

I'm running a stock 4 side suffer with a 3.2 and have no complaints at all. I only use 1st gear on a hill, and for street gearing I think it's fine.
FWIW, if you get the right shift rod, bushings, and a well built tranny, your car should shift fine. I have zero complaints about how my car shifts, and for me anyway, upgrading to a $500+ shifter is a waste of money. |

you are correct Jim , however the 914-6 does not utilize the cable guide as do the 70-71 901 pull clutch cars do.
