Swapping RB25DET auto trans with RB20DET manual

[Jost]

Does anyone know what kind of problems I am likely to encounter swapping an R33 RB25DET auto trans engine with an R32 RB20DET manual trans? It looks like the next shipment of clips from a company I've contacted, are going to be auto transmission equipped R33's. The chassis that I want to make the swap in is a '95 MT S-14. I'm not sure yet if the instrument cluster is included in the R33 clip, or not. They offered to throw in an R32 RB20DET manual transmission with the clip. I'm thinking I should probably steer away from this deal. What do you think?

Thanks in advance,Randy
