I got a series 5 turbo swap in a 91 gxl just blew up my na tranny... and I want to know if a ribbed tranny out of a rx4? will work without modifications to the drive shaft.... I heard theese trannys are almost as strong as the turbo 2 trannys....

 

No. Bellhousings are different, you wouldn't be able to get a starter to fit. You need a TII tranny, S4 or S5.
