1990 FJ75 Troop Carrier Drivetrain options. Poll.

[MES]

Hey Everyone,

Finally finishing up a house renovation, its time to get back to work on the Troopy.
The 3F runs great, but It just has no power. I don't mind the bad MPG, but the power to MPG ratio just doesn't make sense.




Im replacing the 3F with a 1FZ-FE CoilPacked engine from a Saudi spec FZJ100 5spd. ( purchased from a forum member.)

Here is the dilemma... Do I keep the swap simple and keep the H55f and Spltcase and just use a FJCO 1FZ to H55f adapter... or do I swap in a H152 ( which I already have NIB sitting in the garage), and source a HF1A , along with all the crossmembers, linkages , labor, etc.


Will I really be gaining anything by upgrading to the new trans _ Transferase? Max tire size will be 35".

Will not be adding a turbo or power adders. I want a smooth running, simple reliable Toyota gasoline engine.

I will not be doing the swap myself. Don't have the time or space. So Labor cost is a concern.

Any Input will be greatly appreciated.

Thank you!

do what Toyota did. H55 might hold up pretty well, but Toyota spec'ed the other trans, must be a reason.

H55F is ancient.

H152F all the way.

H152F all the way.

Hello,

x2.

Is the 1FZ from a manual transmission truck? Automatic transmissions use a different ECU.

Get an HF-1A transfer to suit the H152.

H15x/HF-1A is just great. Swap it in and do not look back.

H152 1 million percent.

Dave Stedman has a list of the HF1A T case linkage parts all set to go. I just bought three sets from him.

Get a VDJ78 crossmember and frame to crossmember mounts.

Go.

Try these...verify fitment before purchasing:

HF1A 36120-60351
Gusset, crossmember 51321-60090 x2
VDJ7x crossmember 51202-60270
Boot, shifter 58280-60150
VDJ 7x floor plate 58013-60071 (HDJ 58013-60011 is NLA, VDJ seems to fit)
bolts for shift boot to plate 91673-80616 x6

That should get you started. I just went though this with my 79 builds.

Thanks for all the input!!! The people have spoken.

Ordering parts now.

1FZ did come with the Manual Trans ECU. No O2 censor required either.
