So, I tried a search for this and after 6 pages i really came up with nothing.
 
I am swapping a 60A trans into my 1200 and almost all of the questions have been answered but one.  On the A14 motor that this trans came off of, there is a plate that goes inbetween the block and trans and it is about "1/8 thick.  On the 1200, there is just a thin dust plate that attaches to the front of the bellhousing and covers below where the block meets the bellhousing/ trans.  Both transmissions measure out to be the same length.  Once I had the original trans out of the 1200 i was thinking about using the thin dustshield that was matched to the 56 trans because it appears that some of the holes have been made larger in order for it to mount to the 60A.
 
Anyone have any ideas about this or possibly have run across this before?

The plate on the left side matches to the 56 4spd and the one on the right matches to the 60A 5spd.

As long as that bottom dust shield does not interfere with the 1/8" engine/trans plate it should be fine.

A14 flywheel, shirt collar, then use WITH 1/8" plate.

Which is good because I didn't want to change ALL that shit around.  Also could not remember what it all looked like when I took it apart back in '11 or '12.

sometimes you have to massage the side of the tranny tunnel for a sender clearance 

and you have to modify or make a trans cross member

Both of my coupes started life as autotrajics (at least that is my story and I'm sticking to it) so larger tunnel. The 60 series trans has a mounting point farther back on the tail case that I think is for a different type bracket

(stabilizer of sorts if you will) and this lines up very well with the body mount points.  The 56 series trans was installed by PO and pretty much had a U bolt over the top or the case and into the bracket that

holds the mount.  It was quite redneckian if I do say so myself.  Forgot to take an oic of it, so maybe later.  Trans was stabbed this morning and now just putting everything back together.

Excellent info! I'm about to do this upgrade and I had no clue about the flex plate or what T/O bearing was used :thumbup:

Had to leave for a couple days and was not able to complete this.  Hoping to button it up in the next few days and will post the results (success or failure).

I'm hoping for success.

 

Are you using the stock 1200 clutch or A14 or ??

Stock 1200 clutch.

 

Here is some curious info....from a Nissan quick reference book that I used in the late '80's.

1200 clutch disc: 30100-H8900

B210 clutch disc:

4spd 30100-H8900

5spd 30100-K0500

210 clutch disc: 30100-H8900

I did not look in the actual catalog that I have to verify, but I think something is screwy with the 210 listing.  It seems they should list a 4 and a 5spd clutch like the B210.

 

FWIW, the 5 spd I am using is out of a 210.

Kelmo,

Right now I have a stock 60A 5 speed (non dog-leg) in my race coupe. When I went to the A15 I was still using the 56 series close ratio 4 speeds but as is well documented they have issues behind the larger engine. The motor uses a 14lb A12 flywheel, I'm using a standard A12 clutch disc with a 550kg pressure plate. I mix and match clutch discs based on thickness, over the last 30 years I've simply gone though my box of used clutch discs and install the best one. While I'll admit it's a bit hillbilly I've also never had a failure. Granted it's a race car the miles are low and I take off from a standstill very gently.

This summer (off season here in Vegas) I'll be going through the tranny as it's got quite a few miles on it (came out of a 140,000 mile street car). The rear seal is barely leaking so the flywheel needs to come off, at that time I may remove the engine plate to shed the few extra pounds fortunately I have both style of throughout bearings.

Tom
