I am wanting to know whicj tranny is a better performing tranny. The GSR or the SIR II tranny. If the GSR tranny is the better what Axles,tranny mount, and shift linkage would you use if you were to put a Sir II engine with GSR Tranny.

 

axles/shift linkage/mount are all the same.

which engine is it going in?? and what are your mods....the SIR tranny has really close gears...as does the GSR, but not quite as tight.
