Discuss: FJ62 5VZ-FE Conversion

filling in the blanks.......

i know that a lot of my previous replies to this topic have been fairly generalized and i left out some engine groups. i did this on purpose as to not get too long-winded with my replies.
if you need any more detailed info i'll be happy to provide it given that i know the answer.
one of the engine groups i purposely left out are the toyota 4 cylinder diesels, turbo or non.
i have only ridden in one bj60 with the 3B. i don't think i'd ever convert a 60 from any other engine to a 3b. you won't gain anything but possibly a little fuel economy. hope you're not in a hurry.....
i am currently working on a "BTJ60" ( 13bt into an fj60 ) conversion along with an h55f and vacuum shift split case. the truck came in with a tired 2f that would'nt pass smog. i know we're going to gain some fuel economy for sure, possibly even some performance. if not, then we're going to add an intercooler. i also rebuilt the solit case while we were at it and converted it to mechanical shift from the vacuum shift. i plan on doing a write-up for this conversion and did take a lot of pics while going thru the rebuild and mechanical shifter conversion.......

once i get to drive the BTJ60, i'll have somehting to base my opinion on. until then, i can't really pass judgement on this engine group.

two main options

when it comes down to it, i think there are two very logical options for your fj6x powertrain transplant:

1) toyota turbo diesel 6 cylinder with the h55f or r151 and toyota t-case

2) gm vortec series V8 with the 4l60E and either the stock split case via an AA adapter or a stock gm np241 t-case, which could "require" a centered rear diff ( see above ).

if i were you, i'd try to find a few guys who have 60s with conversions and drive them if at all possible. you can read about this stuff all you want but until you've driven one, you just don't know how they perform and behave on the road and off the road.

best of luck!

more 241 info.....

the np241 t-case was used from 1988 and up in gm 1/2 ton trucks, full size blazers, thoes and suburbans.

for the first few years, from 1988 thru 1991, they came in two basic styles: driver and passenger drop 9 front drive shaft output ). the solid axle trucks like K5s and suburbans had the passenger drop front output which lends itself to a conversion in a cruiser. the pickups and tahoes always had the driver side drop front output due to the IFS front axle.
the cases also came with a mechanical or electronic speed sensor. they can be retro-fitted for each other by changing the gears/reluctor wheel, extension housing and sensor/speedo bullet. it's a simple job.
the bolt pattern on all gm 241s is the same, so a passenger case can be substituted for a driver drop case and vise-versa.
as mentioned before, i have rebuilt several of these cases. we even ran one in a tube buggy for a while until the owner could afford an atlas and it held up fine. better than the stock d60 shafts anyways. :nuke:
