Re: What & How to do 5 spd conversion? (archive)

I just did an auto to 5-speed conversion on my coupe. It cost me a total of $1300-$1400, and a lot of time and scraped knuckles. Well worth it, though. Dropped my highway RPMs (and noise) way down! I was very happy with the results.

I went through Jim at Mesa Performance at 800-221-MESA. 4 to 5-speed should cost less, because you can use the same flywheel & clutch (I think). I had to get pedals, hydraulics, etc.

Mine is a getrag O.D. unit from a 528i, but I'm not sure what year. I'll help you with specifics, if I can.

For me to do a 5 speed manual transmission conversion from my 4 speed in a 73 3.0CSi do I need to get one of the following transmissions:

80� or 81� 528i, 635 or 735,
82� 528e, (the bellhousing won't fit, will use old 4spd housing,)
85� 535I,

82� & 85� 528e's and 85� 535,635 and 735's, as well as E30 M3's
need the shifter assembly and speedo drive from the 80-81 528i.

Should use a 80-81 Getrag 5 speed to get a speedometer drive.

I would also like to make the short through shifting conversion while I am at it. Is this possible and worth it?

Does any one have a list of what is required to do this conversion, or a how to description? Does any one have the part number or model number from the transmission so I can find one easy if it isn�t in a car? Please let me know. Let me know if you have a spare one as well that you could part with.
