I have a Y1 cable tranny with LSD and also an S1 cable tranny.

I would like to build a hybrid transmission with the LSD and 5th gear from the Y1 put into the S1. Is this possible?

Yup.

 

Without carrying over the(undesirable)taller 4.266 FD of the Y1?

 

I have an S1 tranny on my b16 right now but the revs are killing me in 5th gear.

How advantageous would it be for me to use a Y1 5th gear? or is it the same as the S1 5th gear?

 

Haven't actually worked with the trannies myself but perhaps this site will help y'all out..

What is the FD on the US SPec S1/YS1 from the 90-93 Integra LS/GS.

one site says 4.4 http://tiiite.b16a.com/GearRatios.htm

one says 4.266 http://www.ff-squad.com/Bgears.htm

which is it?

 

S1 = integra xsi = 4.4 fd
Almost identical to the YS1 cept some gears are slightly shorter.

 

there was also a US version S1 and YS1 that was on the integras with different gearing than the JDM S1 and YS1.

Does anyone know what the FD is for the US integra LS tranny?

 

straight from my 92 Integra Helms manual.....

the 92 LS trannies come with a 4.266 FD
