Basically what you guys are saying is that the H165 can not cope with sustained 200BHP+ action.

Thats a shame, what else can be used that can cope with about 250-270BHP? Rememeber, I am in UK, so maybe all alternatives suggested may not be avialable to me.....BTW, the H165 is in a Datsun Stanza

I am seriously considering buying the H165 LSD that TopGear from this forum is offering. However, i would like to find out what people's experiences are with the sort of power that a H165 can handle.

Presently, my car has about 200bhp@fly and 210lbs/ft and it has an open diff H165 from a stanza. Future mods include a Ca18DEt, pushing around 250-270Bhp. Can the H165 cope with the increase or will it snap halfshafts?

As I am in UK, we do not have H190's easilyavailable, nor for that matter other bigger/stronger diffs.

Thanks
