Hey I have been searching and there are so many possibilities for mounting this swap im having a difficult time putting together all the info.

I'm swapping an rb25 into my s13. It has an rbb20 trans and r33 front crossmember with stock mounts.

I know I'll be able to use my s13 driveshaft but im confused if the transmission mounts will line up and if it will clear the sway bar. Can anyone speak on this exact setup? Oh and will I have problems with the shifter position?

Thanks

Just to make sure your saying
Yes driveshaft
Maybe swaybar and transmission mount
And shifter will sit 1+ in forward

Does anyone know defiantly about the sway bar and transmission mount?
I'll find out soon enough when the motor goes in but I was hoping to get some parts ordered if I need em

Shifter is easy to fix if you have a mig welder, just cut the shaft and put it at an angle.
The mount is not as easy, you pretty much have to make one. You can start with the stock mount and weld a plate on it, it is not that hard to make. Please do not do the one bolt per side trick, it does not work out so well.
