Changing my automatic to standard

Post by Rheis » 13 Sep 2004 19:55

I have a 71 datsun 510 and am looking to convertin it to a standard. I was wondering what would be involved in doing it and what transmition i should use. I heard a 200sx tranny is supposed to be a good pic.

im in the same boat as you. except im just swapping it to a regular 4speed transmission. i have a basic idea of what you're going to need:
clutch pedal and brake pedal from a manual tranny 510 car. then the rest of the obvious things like the clutch, flywheel, shifter, clutch master cylinder, clutch slave cylinder.
i think you're going to need to cut the floor as well to clear the shifter. im gona be starting this week, hopefully be ready the next.

do not forget that you have to change the pilot bearing,when cutting the hole in the floor for BEWARE of the brake line that runs along the tunnel to the rear of the car,it is really close to the area you will be cutting.

i did it on my car. you have to take everything apart in the dash to get the new petals, in. and its a good idea to go strate to a 5 speed, because the hole for the shifter is closer to the auto hole. and you'll need a custom tranny crossmember and a shortend drive shaft. if your converting to standerd its probly a good idea to go strate to a 5 speed.

Actually, you don't have to. All the L16s had the pilot bushing whether they were auto or manual. And the bushing in an auto car would be just like new. :wink:

Actually, you don't have to remove a single thing. I have done three conversions and never removed anything but the pedals. 8)

You don't need to remove the pedal assembly, just fabricate a perch for the clutch return spring. I just got a clutch/brake pedal combo.

The only other thing I had to fabricate beside the perch and tranny mount was the flywheel shield. I did not get it from the donor 5 speed.

Here is a good reference outlining the steps;

I didn't even do that... :P

There's a hole in the pedal box just above where the perch should be, Just clip the spring into that hole. :wink:

It will make the pedal movement just slightly stiffer than stock, but I actually prefer it that way.

And to save you the trouble I had, remember this one thing:

THE BOLT HOLDING THE BRAKE PEDAL ON IS A BACKWARDS THREAD!!!!!!!!!!!!!

I broke one finding this out. ;)
