Hey guys,
New on this forum and was hoping someone may be able to help me out.
Looking to swap a 4jb1t into my upcoming fj40 project, but have been unable to find a part time manual 6 speed gearbox to suit, or find anyone who has mated a 4jb1 (or similar) to one.
This is the last thing I need to sort out before I can get all the engineering, etc sorted so I can start the project.
Also I haven't been able to find much about the differences between the old and new engines other then a slight change to piston design. Is there any benefit to the old vs new or vice versa. Engine age shouldn't be an issue as it should fall under the year of the 40 series body (pre 4jb1t production)
Fyi the plan is a lengthened fj40 body on a cut down j90 prado chassis (~100" wheelbase) with a 4jb1t engine and some kind of 6 speed gearbox with a part time transfer case.
Thanks
Luke
