Outer Limits 4x4 Board

Got an opportunity to buy a good HZJ 75 4.2 ltr diesel off someone who is putting a chev 6.2 into his. I want to know about the compatability with my H55T g/box into my FJ 73 and any other info or experience anyone has.

From what I have read they are exactly the same gearbox. You shouldnt run into any problems.

awwe... hmmm good good you for see the dark side mmm good...yoda voice... what took ya so long rosco

Jake Ive always been a diesel man,dad was a truckie.The FJ 73 come a long and was such a bargain i couldnt resist it. Also I didnt want a troopie because their too big and I didnt want a ute or traytop because of the limitations. I dont know why Toyota didnt sell these in oz with diesels in the 1st place.I didnt want a 4 cyl diesel for long trips
Any way I ll have to fit filters , new power steering pump.Other things to think of Im not too sure about is radiator, aircon, air filter, some way of turning it off at the ignition switch.
Some ones got a 60000 klm HZJ 75 rolling chassis with motor , gear box t/case for $5000. Donor vehicle would make it easier .

Rosco, the gearbox will have different input shafts. See if you can get the tranny off the HZJ75 and it should bolt to your transfer.

The radiator will be fine as the the inlet and oulet are in the correct position. You will need to fabricate the motor mounts as they are different between the 3F and the 1HZ. The fuel shutoff solenoid should be simple enough to connect to the ignition terminal.

I'm sort of in the middle of a 1HZ swap into an FJ40 but I got bogged down by other projects

Dave

Thanks for that beanz . I kind of suspected the input shaft would be different.

they are different boxes. Im not sure if there is a conversion available either. Try the rod shop.

How much is the motor?

Don't they have identical gear ratios, and identical output shaft?

Yeah, identical ratios, output shaft, even bellhousing (clutch housing) bolt patterns. Just different input shafts.

Dave

H55, and R152 (i think) definitely different, one is cast steel the other is aluminium.

Maybe they do interchange!!

The HZJ75 still had the 21-spline input H55 I think. The R151 doesn't start until the HZJ78/79. Rosco's FJ73 should have the 10-spline H55.

Dave

the 3B input shaft had 21 splines right?

Do any of you guys have any more info on the R151? Im putting a supra motor which had a R154 manual into a landy with a R151 and was wondering if the R154 and R151 bellhousings are identical, so I can just buy a R154 supra bellhousing from the wreckers.

Hmmm, I don't know. Never checked it on a 3B engine, but the ones I have seen have a really long input shaft, so I doubt the 1HZ bellhousing will work. But I know you can fab anything, Rob

ROFL yeah the B series input shaft was weird cause it had heaps more splines but was way too long.....

yeah cut and weld the bellhousing

Ok will you guys stop doing piss circles on my driveway and gimme back my thread
This is the plan.Im going to look at a HZJ75 rolling chassis with motor g/box diffs powersteering suspension and a heap of other stuff . Its a 93 and the current owner has had it since the rollover and guarantees its only done 55000klm. He is a cruiser head and owns several and planned a rebuild but never got around to it .
I think this is the best way to go about it as I need the suspension and power steering anyway. Its gona hurt the pocket but my old motor g/box and t/case are still good and I hope to recoup some of the money.The cost of the rolling chassis is 5000 neg. I think I have to get new mounts huh?? or can I use the ones off the donor and reweld em on to the 73.

sorry for hijacking it. I am also looking into putting a 1HD-T into my HJ75. From what I can see in the parts books, the welded on mounts to the chassis are different between the HJ and the HZJ frames. I suspect it is also the case with the FJ73. I am planning to get the chassis mounts from Toyota if I can't get them used, but having a complete rolling chassis is the less expensive way to go. I would just cut them out from the donor and weld them in.

Let me know if the HJ73 gauges and the senders work with the 1HZ. From what I can see the HZJ75 gauge cluster will not mate with my HJ75 wiring.

I can't tell you if AU$5000 is reasonable for your part of the world, but for me it surely is.

Why do you want the HZJ75 suspension?

Dave

I glad you asked me about the suspension.Come to think of it , it might be different.Im still thinkin about selling it and buying a low klm import.Cost me the same and keep my hands clean and less headaches

The front suspension may be similar but the rear will have much higher spring rates.

If you want to sell the HZJ75 rolling chassis I am interested. I have a friend near Perth who may be able to handle the shipping for me. I'll have to ask him first, LOL.
