Hey fellas, im after a 3.7:1 diff centre.

It must be a H145 (i think) - Well it must fit in my Sunny

I am unsure what they come out of but i know they were made as i have come accross some in the past.

Please comment or PM me asap.

How much you looking to spend?

depends, firstly do you own one?

I wouldn't speak if I didn't own one. It is in superb condition. In fact, it's brand new, in it's Nissan box. So I ask again how much are you looking to spend?

Reason I ask is they are difficult to find and exceedingly hard to find brand new. Kindly answer my question and I won't waste any more of your time.

no worries, sorry mate didnt mean to upset you lol.

i would spend what it would take to get one!

how much do you have on it?

H145 did not come in 3.7 ratio.

H150 did, and was fitted to some B210 and some B310 Sunnys.

DD - What does the H145/H150/H165 stand for?

Is it something to do with the axles or crown wheel measurement.

Just curious.

And in that case, what would my 1981 Sunny Sedan have in it?

It fits 1000 Centres if that is any help.

Thanks.

H stands for Hitachi. The number following is the diameter of the ring gear (crown wheel) in millimeters.

B310 all come with H150. There is no other that I know of. B210 sunny came with three different types, but B310 only came with H150.

Okay mate.

Are 1000 Sedans, Utes or Wagon diffs able to be used in the H150, as they are a H145 arnt they?

H145 can go into H150 and vice versa.

The only combination that can be corrected (relatively easily) so as the axles are turning truly concentric (?) is the H150 diff centre into H145 diff axle assembly + diff spacer.

I think with the H145 into H150 you end up with very very slight toe out.
