stangracr Posted December 30, 2007 Share Posted December 30, 2007 I know a guy that has a H190 rear diff. Can anyone tell me what this might be worth and is it a bolt in for a 76 280z? Thanks ed bettis Quote Link to comment Share on other sites More sharing options...
Vintage Posted December 30, 2007 Share Posted December 30, 2007 Never heard of an H190. If its an R190, I believe those were Datsun Comp. differentials. Quote Link to comment Share on other sites More sharing options...
Guest TeamNissan Posted December 30, 2007 Share Posted December 30, 2007 There IS a h190 but its a complete rear with axles not for use in a 280z without SERIOUS modifications. If your going to go with a solid rear instead of independent rear like found stock there are far better options. If you search you will find a few members have swapped solid rears in there s30 for drag purposes. Quote Link to comment Share on other sites More sharing options...
Vintage Posted December 31, 2007 Share Posted December 31, 2007 Oh, is that one of the solid rears from a smaller Datsun? Quote Link to comment Share on other sites More sharing options...
Guest TeamNissan Posted December 31, 2007 Share Posted December 31, 2007 I'm not sure about the H190 itself but I believe the H series is found on roadsters, 1200's and the such. You never really hear much about it here because z's have always had independent rears. Installing a solid rear would really only be beneficial for dragging and at that there are so many better options usually domestic. Quote Link to comment Share on other sites More sharing options...
stangracr Posted December 31, 2007 Author Share Posted December 31, 2007 Guy told me it was a H190. It must me a R190. It looked like my R200 he said it was a comp. rear end from datsun with a locker. Quote Link to comment Share on other sites More sharing options...
Guest TeamNissan Posted December 31, 2007 Share Posted December 31, 2007 Ok, well if that is the case you need to find out which model r190 it is. There are weak 2 bolt ones and stronger 4 bolt one. Should be about 600+ depending on that and condition. I believe it is a direct bolt in with 240z half shafts as a r200 like in your 280z uses 2 dif sized axles. Knowing now its a R190 you really do need to search, there is a sticky with all nissan difs covered within, including the r190. Quote Link to comment Share on other sites More sharing options...
stangracr Posted December 31, 2007 Author Share Posted December 31, 2007 Okay I just talked to the guy. He claims to be a datsun Z person. He said this is a competition datsun rear and that it is a H190. He said all the competition rear ends from datsun were H rears and he never heard of a R190. So who knows. He says this thing was from a race guy that only raced Z cars. I have looked at it put not close. I do know it didnt look like anything special but it did seem to be a locker type rear. Just a quick question. I noticed when my 280 is on jack stands and i turn the right rear tire it doesnt turn anything. Driveshaft doesnt turn and it doesnt turn the other wheel. I also tried to see what the gear ratio was by counting the driveshaft revolutions with one full revolution of the tire. It did not work. I have done this with ford 8.8 rears all the time. All of this is what made me wonder if my R200 was hurt. Quote Link to comment Share on other sites More sharing options...

Dragonfly Posted December 31, 2007 Share Posted December 31, 2007 Here is a link to Les Canadays website http://www.classicdatsun.com/. Les is the owner of classic datsun and the guy who purchased all the remaining stock of R190's and parts for them from Nissan, Les also probably knows more about that particular diff than anyone else. I did notice that he doesn't have anything about them on his website but if you were to call him or email him I am sure he could enlighten you quite a bit.

All of this is what made me wonder if my R200 was hurt. He must be confused or misinformed. H190 are live axle diffs. R190 are IRS Diffs. R190 were fitted to cars like the Z432R and the works rally 240Z cars. Which is probably why he's never heard of them. H190's were fitted to cars like the Cedric, Stanza, Silvia (200SX) etc. H190 will not fit in a Z, and if he got it from a Z guy that only raced Z's then its probably unused, unless he used to race other datsuns.

johnc Posted January 2, 2008 Share Posted January 2, 2008 As posted above regarding the H190 and R190. The live axle rear diffs for Nissans are sold as a pumpkin without the whole rear end housing, the same as Fords rear ends. The seller is mistaken and the H190 rear end cannot be installed in a S30 or S130 unless you're going with a complete live axle swap.

JMortensen Posted January 2, 2008 Share Posted January 2, 2008 I'll add that if it is an H190 and it does have a detroit locker or an LSD, it probably would have some value to a guy like Les Cannaday, because the locker can be installed on the R190 differential and used on a Z in that way. On a side note, it sounds like your R200 is SERIOUSLY busted if the power can't transmit from one side to the other. Quote Link to comment Share on other sites More sharing options...
