Auto to 5 Speed Manual Conversion
or .. so, you'd like to convert an auto to a manual?
by Stuart Mollart
Yep that's what I said to myself. So after
quite a bit research I decided to buy another 928 a 1980
928S 5 speed and transfer the whole drive train (less the motor)
into my car, sounds easy... HA!
Info about auto bodies.
If your car is pre 1986* you have the clutch master cylinder
mount on the firewall. This is good - as all you have to do is drill out the
holes that were covered up. If your car is post 1986* then you don't have the
mount on the firewall, and you must do a firewall transplant - cut old one
from manual donor and weld into the auto body - well I'm not going to get into
that process - check out
*RHD cars - don't hold me to
these dates - due to variations in production runs etc. - check the
firewall on your 928.
What's required in parts?
Pilot bearing for rear of crank
Clutch assembly inc. clutch fork
5 speed box
Gear shifter & boot, facia etc.
Clutch master cylinder with connection rod
Clutch slave cylinder with push rod & hydraulic line/flex hose
Clutch/brake pedal assembly
Micro switch for cruise control, rubber stopper for clutch pedal.
Reverse switch/speedo pickup
Wire link to bypass auto lockout relay
Well what a fun job it's been, it's not a difficult job. If you have the space,
tools and patience.
Cost: about $7,500(AUD) - most of that's the cost of the
car and a handful of minor bits and pieces. Second hand parts come to about
the same cost - if you can find them.
Time: that's a hard one - estimated 30 hours of no mucking about - otherwise
about a weeks work.
Can you see the difference?
