datzenmike,

 

I pulled the fill plug and found it has steel syncros. 

 

Cranked the engine over by hand 10 times and found the output shaft rotated about 2.5 times.

 

Did you mean 10 crank shaft revolutions or 10 complete engine revolutions?  2 crank revolutions = one engine revolution?

One crankshaft rev is one engine rev. 2 crank revs is one complete 4 cycle.

 

10 crankshaft turns in first gear should turn the output

 

 

 

close ratio............... 3.38 times

 

mid close ratio........ 3.73 times

 

ultra close ratio....... 5.38 times

 

 

Sorry Doug the picture was from an FS5C71B competition (Nismo)unit. Corrected my text on the 5 speeds.

I am having a hard time with this, there is no brass.

I turn the imput shaft 10 times and counted 3.38 turns, I bought this from a Washington resident along with a bunch of other U20 parts and a 411sss oilpan, he expressed that he had put new bearings in it.
It has what looks like the same synchros that the R16 4 speed has(bottom access plate) that I put in backwards and had to redo 3 times before I got it correct.
I am suspecting that this transmission has issues, otherwise why would he have sold it for so cheap.

Oh sweet, another thread for the tranny whores to get there jollies off on... so jelly for your close ratio box. I've got the fs5c71b datzenmike posted.. . Wide ratio :(

 

I'm not sure mine is close ratio or not.  Based on turning the input 10 times and have about 2.5 turns on the output. That says it is not a close ratio box.
