I originally posted this in the 60 section, but didn't recieve any help, so I'll try here. I've been trying to decide what I should do with my FJ60; engine wise... Keep the 2F and convert it into a 2FE, go with a 2UV or try out a 1FZ. (I don't really want a chevy engine) I would like to keep it a manual with a part time transfer case and while fuel economy is what I'm going to say i'm looking for, I secretly desire power just as much as the next person, but I have no need for anything above say 400-500hp. I also am trying to keep expenses down. Lately I have been researching into the possibility of a 1FZ-FE engine, but there is the problem of sourcing a H150 (151) Tranny and the almost non-existant H1FA transfer case, however, some of my digging in the forums has led me to another possibility... Looking through the threads I've ran into: The 1HZ engine used in Prado's was mated to the H55f transmission, the Bellhousing for this (Part#31111-60230) will also fit a 1FZ-FE engine. (I don't know if that is fact, thats what was stated) Then it gets a little murky: A 300mm Isuzu Clutch (Part#8-97389910-0) can be used. The fork assembly, release bearing assembly and release cylinder from the 1HZ/H55f setup has to be used but the pressure plate and flywheel would have to come off of a 1HDT. A longer 21 spline input shaft is needed. Or: The fj60 clutch can be kept, if the spigot bearing is removed from the crankshaft and a bushing is machined to make up the difference in length then fit a new spigot bearing in the end of the bushing. Most of the ideas I found about mating a 1FZ to a H55 have been in the Diesel Tech area. I was wondering if anyone has been thinking about how to do this conversion that may have come up with something, what way to deal with the clutch, and the different lengths of the input shafts (and possibly different number of splines) or if there is something that makes this totally impossible. Thanks for the input.
