Rb25T Gearset Is Not The Same As Z32Tt

[tm_r33]

so after every one telling me that the 25gtst box had identicle gearset to the z32 tt i have since bought a z32tt box for the gearset in the hope to use my 25 bellhousing and extension housing..... BUT....

the z32 is shorter.... the main shaft seems to be 80mm shorter than the 25gtst. SO bellhousing change will be fine... but if i put the 25 extension housing on the back it will be too long for the main shaft if that make sense??????

wtf.

and if i leave z32 extension on the back which appears to be shorter then my tailshaft will be too short???

Who told you that? The cluster and mainshaft gears are much the same I think. The shafts themselves could be another story...

i have both boxes and they are not even close to the same lol. a quick measure up gave me the figure of 80mm difference......

they are not the same gearset.... they have the same sandwhich plate and the input shafts are the same length so i can use my my 25 bellhousing on it and ill just get a single peice tail shaft made up to make up the 80 mm extra length i need for it to be long enough
