How much is too much?
How much power/torque could an SJ80 gearbox be reasonably expected to handle?
Re: How much is too much?
SJ80 being the first coiled zuk after the samurai? Same gearbox/transfer as SJ413 and leafsprung samurai (t/c was chain driven in jimnys I think). Ive read the gear driven transfer cases are good for 200hp pending on mountings. If no one else answers, I read in latest 4x4 action mag, Nathan Fogden (ex A class nat champ) is running 1300 gearbox with what I assume is rockhopper t/c (written as cowper special gears) someone correct me if Im wrong, In front of all this is a supercharged J20 (2L zuk engine) which must be 150 plus hp). Its geared down through 4.88 hilux axles on 32" simexs. If your set up beats that, it would be interesting reading

That's the one.
I have a 410 transfer that can replace the chain driven one but that poses the next question...are the diffs up to it

If I were to put hilux diffs under it how would they go with the offset transfer output?
Don't really wont vibration issues.
