Rb25det S15 swap gearbox mount

Hello,

Im currently part way through a rb25det neo swap into my S15 silvia.

Car was factory sr20de auto but was manual converted previously.

I am using r33 front subframe and engine mounts and am using the stock sr20de gearbox with a rb20de bellhousing to make the box the same as a factory rb20det small box.

My issue is the gearbox is sitting around 1.5inchs further back than factory location so the mount doesnt fit and the driveshaft is too long.

Everything I read online said using this small box means I can retain factory driveshaft without mods. Was this wrong?

Is there a different crossmember I could use? How can I use factory driveshaft??



Thanks

Issue is using r33 crossmember. Thats why everything is pushed back. I know for a fact rb20 trans will work stock location/mount n driveshaft. Just use oem subframe n make custom mounts/or find some that sit in proper location
