Outer Limits 4x4 Board

hi ive got a fzj75 1fz-fe and im pretty keen to swap in a 1hz. any help you guys could give would be great, the box is the h150f, what 1hz blocks fit this bellhousing? are the input shaft and ratios different? will the mounts need modifying? any other details? eg tricky wiring or fuel setups... ive been searching around and this doesnt seem to have been done much, not to a 75 anyway. trading cars isnt really an option, ive done too much to the girl and i want to keep the h150f box.
any help or advice would be awesome, cheers

whats the reason u want to do this for. as changing to a 1hz seems a big downgrade in power even if u turbo it u won't get the same grunt.

1fz 75's are rare. if it's an economy isue put it on gas or turbo it save urself some money that way too.
