4bt in a fzj80

[fernandol]

I am swamping the 1fz for a 4bt and have various questions.

First I am currently looking at 2 4bts. One has the factory aftercooler which will make the swamp easier but is 2 or 3 inches taller than the regular 4bt so am not sure if it will fit under the hood of the 80 with a 4" lift. The other is about 750$ cheaper but it's not aftercooled so I would have to fit an intercooler which will probably mean changing the radiator.

Any one has experience with aftercoolers? I like the idea of not having to change the radiator. The engine is rated by Cummins at 120 hp just like the intercooled version.

I am also swamping the auto for a NV4500 mated to a split transfercase from an fj60 so there will be nothing requiring electronics. I guess the ABS, cruise control, and all other ECU controlled features will not operate any more or will they? can I hook up some of this things with out having the engine or transmission hooked to the ECU?

I feel pretty comfortable with the fabrication work and with the mechanical part of the work, but I have no experience with electronics. How much trouble can these be? should I really worry about it at all or should I just forget about the ECU all together.


thanks

Yes, the 4BTA will fit even though it is a little taller than the 4BT.

If you plan on towing a trailer or turning up your fuel, it would be a good idea to intercool it. Lots of different options. You can aftermarket intercool the 4BT.

Don't know if you know or even care but from a legal factor, the new engine must be of the same technology (read....year) or newer than the vehicle that it is going into. If you put an older 4BT or 4BTA into a FZJ80, it is considered to be for off-road use only. You may have problems titling/registering/smogging this vehicle.

Good luck. It's a helluva motor and works great in the 80 series.
