Hello everyone. Long time since I posted something here.
The story is that i might finally get a complete dissasembled hdj80 for my project.
The idea is to get the 1hd-t into my bj70.
I friend of mine got an 1hz on a 75, so I definitely know that mounting the motor on the bay is very easy (plus a lot of information about 1hz onto bj75 on the web, but not a single bj70 to 1hdt info i could find).
My main concern is what to do with the tranny, since i read different oppinions.
One alternative is to mantain my h55 and get an 1hz bellhouse and source other parts in order to adapt the 1hdt to the h55 (there is quite a lot of information for this)
The other alternative is to put the h151 from the 80 onto my rig
At the moment I like more the idea to use the 80´ h151. The main reasin is that I dont have to source the part to adapt the 1hdt to the h55, and we all know that the h151 can manage the 160 hp of the 1hdt. Cons for this alternative is that, since the gearbox+transfer is longer than the h55, the angles of the ujoint from the rear driveshaft will be high (remember than de BJ70 is the shortest of the 70 series). I might solve this using double ujoints.
The other alternative (mantaing the h55) has the advantage that I dont have to modifiy anything in the driveshaftn (neither front nor rear one). The cons is, firts I have to source everything in order to make the 1hdt to match the h55, which here in Argentina might get tricky. The other thing that worries me most is that I read some time ago in pirates4x4 people saying that the H55 could not handle the 160HP from a 1hdt (which make sence since h55 was used at max with the 130hp 1hz motor).
So this is my dilema right now.
Any imput or information would be very appreciated!
