Hi All,
Short introduction to the 40- & 55-Series Tech:
I’m Yves from the Netherlands, I’m an electronic engineer and am an electronic engineer with my own company. As most on here I love Land Cruisers and am the owner of a Land Cruiser HDJ100 with the 1HD-FTE 4.2L turbo engine. I use it as daily driver, offroad and travel/camping with a roof top tent. No campsites, only in the wild.
There’s not a lot of off road in the Netherlands, but me and my friends manage and visit offroad days and other countries. Somehow I’m always the first one through deep water and to rip his bumpers off.
I’ve always liked the older Land Cruisers, the 40 series, the 40 series pickup and the 60 series, or well, actually all of them. Recently I came across a cheap, very nice, rust free BJ42 from 1984, I bought it with a broken 3B engine, it’s seized, perfect time to swap.
The car is in good condition, I’d like to keep it just a little bit original. I’m thinking small lift, 32/33” mud tires, NOT cutting rear fenders, rollbar, original or 4 Plus style bumper and a nice soft ride. Oh, and a big engine made by Toyota.
For tax reasons I want to swap in a petrol engine. I like diesel but the road tax for a diesel is about €1800 euro and for petrol only €125 per year. There’s a bit more to this than only the fuel difference, but I won’t go into detail.
I’ve bought myself a nice used 1995 Lexus LS400 with the 1UZ-FE (non-VVTi) engine with 265hp and 190,000km/122,000miles on it. Bought it in the UK, drove it home. It’s a nice car with bad paint, interior looks like my 100 series and it drives perfect. It’s almost a shame to take the engine out and wreck/part out the car. But since the steering wheel is at the wrong side of the car I don’t have another option than to use the engine, ecu and hopefully the automatic gearbox in the BJ42. The UZJ-40 is going to be used for on- and off road.
I’ll still have to choose if I’m going to use the H55F five speed manual, or the A340 automatic from the Lexus. I would like to have an automatic and would also make a manual shift mode for the A340 transmission. That way I can just select a gear (2nd, 3rd) in low range and push the pedals. Also a replacement A340 is cheap, H55F is expensive.
Now the input shaft on a split transfer case needs a bearing (the H55F already has one. I was thinking of making my own adapter plate with one, like in these AA kits: 50-1701 : GM 4L80E 4 speed automatic transmission to the August1980-1990 Land Cruiser 19 spline transfer case,adapter kit. | Advance Adapters
Making an adapter plate with bearing for the split case is not a problem, making a splined shaft from the A340 to the split transfer case is also not a problem. I was thinking about using an AW4 tail housing on the back of the A340 transmission, mounting an adapter plate to that to accept the Toyota Split case.
My only concern is total driveline length, and related to that, rear driveshaft length.
I have no problem moving the engine forward a bit and using an electric fan on the radiator.
I could not find a whole lot on 1UZ-FE swaps in 40’s, so I want to share what I learn and how I do things. I’d also like your input and feedback and opinions on the project, helps me learn and do things different.
3B engine disconnected:
3B engine out (using forklift):
H55F and Split-case removal (don't worry, I did not spent time under there, front was raised to ride gearbox & transfer case out):
