I'm dead set on putting a diesel engine in my 1991 FJ80, but which one? At first I liked the 4BT until I went for a ride in a friend's FJ60 with a 4BT; power? A lot, would never call it slow. MPG? Unbelievable! 23mpg. But it rattles bad, like someone shaking your seat. And the noise, oh the noise. It sounds just like a tractor with no muffler revving to 3k. Ear plugs, a suspension seat, and it would be ideal.
Next was the 4BD1T which is a LOT quieter because it's a highway engine. Other attributes that are nice about a highway engine are the mounting brackets for accessories, you don't have to reinvent the wheel. It's also 4" shorter from valve cover to oil pan than the 4BT, and its sleeved, and there're quite a few experts out there who are willing to help get the most out of them.
I also saw a build thread for a 4D34T, and I liked the idea of it being a near drop in; bolts up to the A440, uses stock mounting location, just minor mount modifications for shape and strength. Also 4" shorter on the vertical and I saw one with 30psi in an 80 series do a 0-100mph run and it looked like it was hauling the mail.
Toyota engines are out for me because they're hilariously expensive and I've never heard of one making 500ftlbs, I'm sure it's possible, but at what cost? I don't want a $20k 1HDT that I can't get parts for.
I'm really curious about two options that I'm still learning about;
The first is the HINO; its owned by Toyota, but they don't seem to translate to passenger vehicles. Wondering if anyone has put one in a Cruiser and what goes into it.
The other is the QSB 4.5; from what I was told, they are converted for automotive applications a lot in Brazil. it's common rail and computer controlled, but its quiet for an industrial diesel engine. Like all industrial applications the power rating is all over the place, but I've seen quoted power and torque figures of 170 and 440 respecively, I've also heard of 300hp tunes but don't really have a way to confirm that (although it would be epic right up to the point that it broke everything its attached to lol). If I went the QSB route, I'd want to go full tilt; get a trans and Tcase from a pickup/truck with a 6.7 Cummins. I'm sure that Advanced could spin me up any adapters that I might need, Painless could make me a harness, the difficult/interesting challenge would be to find an ECU to run it all. Holley, F.A.S.T, F.I.Tech, and Haltech all make products that basically do what I'm asking for, but there's the diesel factor, and the Tcase to consider.
I'm also considering C303 portal axles, but that might limit highway use.
And before the money issue comes up; a friend of mine owns an equipment rental place and can get any of these engines, so the cost breakdown works like this; the 4BT, 4BD, and 4D34T all cost about the same, $3500 for a good used one.
The HINO is closer to $5,000 used and $7,000 new.
The QSB 4.5 is about $6,000 used(when they can be found) and $8,000 new.
What direction should I go? Don't say 6.2 or 6.5 GM, I blew up one of each in my K5; the block of the 6,2 cracked and a hole was punched in the number one piston of the 6.5, both were too expensive to fix.
