datzenmike Posted September 5, 2017 Report Share Posted September 5, 2017 Welcome to Ratsun Karroulias. I'm aware of the J15 engine being in other models of the 620 sold elsewhere like Mexico. I was not aware that the F4W71B was ever used in them, are you sure? Usually an F4W63 was used. If your transmission has a removable pan with a drain on the bottom it's an F4W63, like this? Let me know what you have. Maybe a picture? If you do have an F4W71B then yes, an FS5W71B five speed should fit right in as long as the lengths are the same. I don't know what would have one in Greece. Maybe... '78 and up 280z '79 and up non turbo 280zx 910 Maxima '80-'83 S110 200sx '84-'86 S12 '811-'86 720 The top two have six cylinder engines and would most likely have the 71B transmission. The other four might have smaller less powerful engines in Europe and have a lighter transmission. I don't know. . Quote Link to comment
KoHeartsGPA Posted September 5, 2017 Report Share Posted September 5, 2017 Doesn't have a "B" from what he wrote, don't know if that changes anything though, just figured I'd point it out so you can guide him correctly ;) Quote Link to comment
datzenmike Posted September 5, 2017 Report Share Posted September 5, 2017 He might be assuming, he may have been told that's what it is, who knows. That would still need the front J series case swapped to what ever 5 speed he finds. Quote Link to comment
